Over the years weve consulted on dozens of pneumatic conveying systems and seen project leaders make every possible mistake. There are lots of variables, as weve shown here, and mistakes can be costly both at the outset and down the line. Our Supplemental System works with an existing blower control panel to modulate blower speed. The rating of the blower is signified in terms of required pressure and volume of flow. Pneumatic conveying equipment is no different. Other mechanical devices may offer some relief, such as flexible screws, Z-type bucket elevators and aeromechanical or tubular drag conveyors. Poly Discharge Cyclone - installs on the bin lid and gently decelerates grain and vents the air stream outside the bin. These systems can be complex, winding and task-specific. Issues like limitations in ceiling heights, costs of large structures and access platforms and raw material access can make the best process diagrams impossible to implement in pure gravity flow alone. For conveying fragile or sheer sensitive products. But whether that material is produced in 24 hours (1,000 pounds an hour), or in 8 hours (3,000 pounds an hour) makes a big difference in rate required for proper system design. They are often very cost competitive for these rates and distances and offer a number of advantages in terms of flexibility, cleanliness and low maintenance. Sterling Systems specializes in designing and developing the best system for your unique applications. It always works (Or at least, if it stops working, you probably will have more pressing issues than your material handling system). Its still the same car either way, but design parameters of how you operate it allow it to operate more efficiently in one mode than another. Extruded shapes like pet food and breakfast cereal maintain their desired shapes for packaging and dont wind up with less product as dust in the bottom of the bag. Pneumatic conveying refers to a type of system that uses compressed air or another gas to transfer bulk materials like powders and granules from one process area to another. In terms of a conveying system, the size of a conveyor for moving 3,000 pounds an hour, over 100 feet, of 100 pound per cubic foot cement may be very different than the size of a conveyor moving 3,000 pounds an hour, over 100 feet, of 6 pound per cubic foot fume silica. That gives you a fair amount of flexibility, which is the second advantage. Make sure each is called out and accounted for in your scope so your system is complete and your pricing is true. Mechanical conveying has advantages in the following scenarios, given the general information already discussed: The reason for most of these limiting parameters is not engineering design or capability, but rather efficiencies and costs. There are lots of variables here, including pipe size, line layout, product density and particle size, to name a few. In addition, the slow velocities of dense phase conveying offer advantages to abrasive materials as well. What are the advantages of pneumatic conveying? If you would like some additional information regarding the most advanced and effective blower conveying systems that we manufacture, Sterling Systems would like to invite you to visit our web site. Heres what to avoid (and what to do instead) to achieve a successful install. The higher velocities usually mean some product breakage during transfer, however in many applications, this is not a concern.Consistently metering the product into the blow line is very important with dilute phase systems. The control unit can integrate to automatically run with the dryer including fail safe features. Every panel is customizable with VFD's, bin level sensors, NEMA 4 enclosure, remote monitoring and control, and can be interfaced to work with your dryer. Designing a conveying system can be a very nuanced endeavor. Vacuum systems still have a place though and can often present advantages over pressure systems in different situations. Dont let inexperience or lingering questions keep you from getting it right. If the same park is two miles away, you may want to take a bike. Pneumatic conveying is about moving dry bulk materials with air. Provides long wear life for horizontal and vertical runs. By controlling the positive or negative pressure and the airflow inside the conveying line, the system can move materials very successfully with very little damage or loss. With this system youll also have the ability to switch bins without shutting down the system. Pneumatic systems arent the best for wet and/or fragile products. We also employ a full staff of highly valued technicians that have spent years in the development and utilization of our systems, and have passed on their knowledge within their work. Because there is less product friction with the pipe and you want the product to be suspended in the airstream, the velocities are high and the pressures needed to counteract friction are low. The motive force for this transfer comes from a combination of pressure differential and the flow of a gas, such as air or nitrogen. Blockage can occur where the active air or gas pressure in the system is at its minimum value. That means maintenance is quicker and downtime is limited. The conveying of material-laden air with fans involves determining the bulk density of the material to be conveyed. Poor piping design can lead to a host of problems. Pneumatic conveying equipment is no different. Take your time. The higher velocity means a dilute phase system is not ideal for fragile or sheer-sensitive products, which can break, coat up and potentially plug the line. Integrate seamlessly with your GSI dryer or expand your system by laying more tube. The higher velocity and sharp turns can damage more sensitive materials and impact the end product. Flow-Command automatically makes adjustments for different bins without any user input. So be sure to design for peak capacity. There was an error submitting the form. Taking the kids to a baseball game across town? Kongskilde Industries offers effective conveying equipment: some blowers are designed for clean air transport, others for ventilation and many host centrifugal units for the handling of material. What are pneumatic conveyings disadvantages? Conveyair's Flow-Command works with the control panel to automatically control the flow of grain to maximize system performance and minimize system wear. Blower conveying systems transfers powders, granules, and other dry bulk materials through an enclosed pipeline. . There are valid reasons to do each. They also dont take up a lot of floor space, so theyre easier to locate. Backward curved fans produce medium to high airflow and produce the highest operating speeds. Our complete system components include: a tri-lobe blower, rotary airlock, and PSI-based control panel. The more information gathered about these factors allow for a more complete and accurate recommendation in system design. The conveyor equipment facilitating the material handling can be composed of various equipment. Comes with a rain cover and replaceable stainless steel wear liner. These materials are usually fairly dry materials, and if they were in a slurry or paste form, they typically wouldnt be suited to pneumatic conveying. - Remember that there is a pressure gradient across the conveying system. That way youll wind up with a system that doesnt just work for your process, but for your budget and your boss as well. Copyright 2021 Sterling Blower | All Rights Reserved. Historically, weaker fans were used to provide the air to the system, limiting conveying to light materials in low quantities. Systems that are extremely short or low rate are usually not cost effective to purchase because the fixed cost of buying a filter and a blower versus the variable cost of the pipe distance, makes pneumatic systems with pulse-jet filters, positive displacement blowers and rotary valves inefficient by comparison to a simple screw conveyor or bucket elevator. This requires lower velocities and higher pressures. For further information contact us or select your product below. Pneumatic conveying equipment, for one, is used to create cost-effective material handling systems. Need to make a cross country trip from New York to L.A. for a meeting tomorrow? If you need to get material from a mixer to a truck load out silo that is 100 feet away, it is also important to remember that the silo is 60 feet tall when you get there. Selecting the right industrial blower is an important decision in the area of material handling conveyor equipment: errors influence material flow rate and may necessitate changes to system sizing and design. For over the last one hundred years, Sterling Systems has been providing the most effective and cost efficient blowing systems and equipment that have served thousands of our highly valued clients. Deflector - 90 degree deflector with adjustable angle. You must also look at the pipe size, distance, and the weight of the material being moved. Particle size, density and length or run all factor into the ratio of product to air. On vacuum and closed-loop systems, any product thats corrosive (e.g., dry salt) or acidic (e.g., biomass) can damage carbon steel, so make sure your contact parts are stainless. If particle size is important to your process or breakage is a concern, incorporate wide-sweep elbows in your system design. Learn more about GSI products and specifications in our brochure library. Centrifugal units designed for handling of material through the blowers. (rate), 3) How many people are going? 286 and is ready to be installed by your electrician. We have many different angle options available for different installation scenarios. This is especially true in routing. When this happens, you probably need to flatten out your stack-up and put in a conveyor. The circumstances of these devices often make a vacuum system more attractive than a pressure system may otherwise be. Dense phase uses a pulse of product pushed by a pulse of air, then another pulse of product followed by a pulse of air. Proven Engineering. In terms of conveying, distance is the first consideration. our Wide Range of Industrial Fan Offerings, Select an Industry Type from the Drop Menu Below to View GSI supports agriculture around the globe with the most extensive global manufacturing footprint and dealer network in our industry.

AMG Custom Controls is a full-service UL 508A panel shop built on 25 years of controls engineering excellence. AGCO Corporation 2021. A third major consideration in pneumatic conveying is the choice of whether to design for a dilute phase system or a dense phase system. If you need more than 300 horsepower from your blower, this may not be the system for you. A short summary of those is below. A wide range of equipment manual, semi-automated and automated is used in bulk material handling, involving consideration of the storage, control and protection of conveyed material. Many of our models are even equipped with self-cleaning rotors. Installing a Pneumatic conveying system in your facility? Galvanized steel tubing. Rotary air lock accurately feeds grain into the system by locking pressurized air in the system. Practical. This is useful in product transfer systems where additional cooling might otherwise be necessary. Directly coupled centrifugal units designed for handling of material through the blowers. Selecting the correct blower is the most important decision when designing a blower conveying system. While some of the most common materials transferred by pneumatic conveying systems are flour, cement, sand, and plastic pellets, many hundreds of chemicals, food products, and minerals can be pneumatically conveyed, too. The difference in prices of these items is usually significant. Thats not to say they cant work for higher volumes. Dilute phase conveying is about suspending materials in an airstream and moving them from point A to point B relatively quickly. These systems have a number of applications including conveying long distances, batch-weigh systems, or multiple pick-up and discharge points. Copyright 2019-2022 Thor Manufacturing Ltd. All rights reserved. If you put in a dilute phase pressure system with no venting, theres a good chance your system will airlock and you wont be able to get your product to fall out of the bin. They also tend to have lower noise levels, weatherproofing, and it is possible for certain models to either be placed inside or outside the production area. There are lots of ancillary components and equipment involved (material storage, loss-and-weigh system, feed system, piping, venting, dust collector, diverter valves being some of the bigger items). The conveying distances are less than 80 feet or more than 600 feet, The instantaneous rates are less than 2,000 pounds per hour or more than 100,000 pounds per hour, There are fewer than 3 or fewer changes in direction required. Blowers can also be used in cleaning and exhaust processes. Installed inside the bin keeping the bin accessible for top loading. Quickly and easily select which bin you are filling from the ground with the CA-Select valve. The positive displacement blower is the engine of most dilute phase pneumatic systems. When conveying dry bulk materials pneumatically, the system designer has to also decide if the system is going to be a pressure system or a vacuum system. A pneumatic conveying process is ideal for fine, dry powders. Does Your Plant Need or Need to Upgrade an Automated Conveyor System? is pretty long, which is why this type of system is very popular for certain processes. Fragile products can also fall victim to the speed and creative routing these systems allow. This is another way of saying you can haul a lot more pounds of bricks than feathers in the same wheel barrow. A properly installed rotary airlock or other metering device with appropriate venting will ensure that the system is reliable day-in, day-out. Gravity Conveying versus Mechanical Conveying versus Pneumatic Conveying. Different hopper and tank options exist to suit your needs. Every PTS system uses our own Thor airlocks, which are precision machined and built from heavy duty components for a long life. That saves plant space and money, and removes a number of potential construction challenges. These systems use high velocities to fluidize the product in the air/gas stream and use a higher ratio of air to product. Correctly specifying the volume of flow rate and pressure levels needed to move the material will determine your systems reliability. Front End Loading (FEL) & Preliminary Studies. These challenges do have design options that can be instituted to allow a pressure system to still function if needed, but may come with additional costs or restrictions. Much like planning a car trip, in order to begin to get a handle on the best road to take, you must answer a few questions: 2) How long does it take/how fast do I need to get there? A pneumatic system works by moving the material through an enclosed conveying line using a combination of pressure differential and the flow of air (or another gas) from a blower or fan. Sterling Systems is the most widely known innovator of the most durable and long lasting blower conveying systems that are on the market today. We know what works. Industrial blowers have centrifugal fans, with forward or backward curved blades, that increase the pressure of incoming airstreams using impellers- accelerating air radially and altering outward flowing air direction. (volume/density parameters). hbspt.cta._relativeUrls=true;hbspt.cta.load(1963460, 'b3ca36f0-e6b5-429c-979d-9de96312e1ce', {"useNewLoader":"true","region":"na1"}); Innovative. Judging by this fact, it easy to see that a large number of people believe that getting from point A to point B often requires direction and planning. While a pneumatic system often may be cleaner, more self-contained and require less maintenance, the sheer costs of running a 500 or so horsepower blower that may be required to make this large of a system work, tends to make the operating costs impractical. These conveying systems are certainly beneficial to a plastics manufacturing plant that must deal with tons of plastic scraps and debris that can easily be converted back into usable materials that can produce new products. Solid cast iron rotors that never go out of balance and maintain their tight tolerance, superior taper lock timing design, and helical hardened gears reduce noise and provide many years of trouble-free service. Grip Coupler - provides extreme holding power. And if one part of the system cant do its unique job, it wont just be the system that breaks down it will be the entire process. What are 10 of the biggest challenges in system design and scoping? Dilute phase conveying sand, for instance, is essentially sand blasting the interior of your equipment from the inside out. Consistently metering the product into the blow line is very important with dilute phase systems. What are the ideal materials for pneumatic conveying? Kongskilde Industries can and will assist in the consideration of all these factors and more, ensuring that the right decision is made. Finally the transport itself can be important based on how many people are going. Safety guards and electrical disconnect. Your privacy is important to us. Author: Larry Eagan | Regional Sales Manager for Magnum Systems, This article is published on POWDERBULKSOLIDS.COM, Choosing the Right Bulk Bag Filling Equipment in the Chemical Industry, Using Robotics to Overcome Manual Palletizing System Challenges, Troubleshooting a Conveying System? If the pipe is sized too small, it will incur a high pressure drop. If you are making a product into a pellet, flake or shape, and want the product to hold this form, banging it against the pipe (especially the elbows in a turn) can be problematic. We painstakingly design, develop and manufacture our most prestigious line of products and systems that can easily process all of your material handling needs. Any mistakes in determining this will result in a conveying system that is either oversized, or isnt capable of achieving the material flow rate required. An added advantage to fan type systems is that the conveying air can be used to cool and aerate the materials being conveyed. These units can operate in either positive pressure or negative pressure mode. In other words, its not what is possible to do, but what is practical to do from an efficiency standpoint. That being said, there are often times you need to go the other way for differing reasons. Like all designs, it is important to know that these are generalizations that are true in most cases, but have exceptions. you want your system to function at peak flow. AMG is a National Minority Supplier Development Council certified Minority Business Enterprise. In terms of our travel scenarios, if you are in St Louis on Wednesday and need to get to Orlando by Friday, you may have plenty of time to drive there and see sights along the way. But which conveying method should you choose? Dont let inexperience or lingering questions keep you from getting it right. 2021. . Check this area often for updated manuals, software updates and limited time offers. Rate also needs to be defined closely. How do I choose between pneumatic conveying system types? Your password must contain at least 7 characters, with one lowercase letter, one uppercase letter and a number. If you are going by yourself down the block to a park, you may walk. But the list of advantages is pretty long, which is why this type of system is very popular for certain processes. GSI reserves the right to change designs and specifications without notice. Our prefilter is built with industrial operation in mind, with an easy air flow path. Conveyair has been building quality pneumatic grain handling equipment for over 35 years. Every airlock utilizes a fixed bearing design, which prevents end play as the bearings wear and allows for tighter endplate tolerance for improved performance and longer life. If you would like some additional information regarding the most advanced and effective blower conveying systems that we manufacture, Sterling Systems would like to invite you to visit our web site. Here are some of the most common, along with a few specific suggestions for how to avoid them on your project. High-velocity air is used to carry dirt, weld fumes, grain, plastic materials, wood waste and paper trim from a process to a collection point. Here are some of the key disadvantages with pneumatic conveying: Now that you know what these systems are (and are not) capable of, how do you decide which type of system will work best for your process? General Information Required Thats bad for business (and for you). Conveying of dry bulk materials can largely be broken into two categories: Mechanical and Pneumatic. The New York Blower Company offers literally thousands of different types, modelsandsizes of air-movement equipment that can be customized and tailored to your specific application. You can move a lot of things with air velocity and power, a tornado is proof of that. A couple can easily enjoy a road trip in a two seat convertible, but if you are taking two kids and Aunt Edna with you from Chicago to Wally World, you may need a sporty new station wagon. A system like this isnt always the best option. Provides the best performance and simplest design for the nearest bins. Then loading up the minivan is a better option.
