Cement Screw Conveyors
As you may realize, there are an abundance of conveyors in the world. They help industries around the globe with production, assembly, distribution, loading and unloading, and an assortment of other processes necessary to keep businesses running. Belt conveyors, gravity conveyors, low profile conveyors - all of these and more keep boxes, parts, and scrap moving and getting where they need to go. What about other materials that aren't so solid? There are solutions for that too. Cement screw conveyors are designed just for dealing with cement and various dust and powders.
Cement screw conveyors, while handling cement, can also manage dry, dusty materials and wet ones. Screw conveyors have a long history, dating back to the third century B.C.E., where they were originally used for irrigation of farms and removing water from ships. In the United States in the late 1800s they were still in use on farms, being used in feed mills where they are still an important feature today. Beyond the farm, screw conveyors are found in most major industries and processing plants around the world.
Just like all conveyors, cement screw conveyors are purposed to get the product, in this case cement or another similar material, from one point to another. Unlike belt conveyors or gravity conveyors, screw conveyors work in volume. The screw revolves, and with each turn a certain amount of cement or another product is released. Where does the material come from? Like all conveyors, there is something at one end or another feeding it. In this case, screw conveyors are usually connected to another conveyor or metering device of some sort, which feeds it. Belt conveyors and screw feeders are among the things that may be attached to the screw conveyor's inlet and feed material into it. In the case of a screw feeder, it itself may be attached to a hopper, bin, or silo and meter out the respective materials into the screw conveyor. The amount of material fed at a time is controlled. There are standards for the amount of material that should be dispensed at a time and these differ depending on the material.
To choose the appropriate screw conveyor for your application, including heavy-duty conveyors like a twin screw, you should first and foremost consider the material that's being conveyed. Standards for sizing and flow rate, among other things, are set out by The Conveyor Equipment Manufacturers Association (CEMA). Any quality manufacturer of cement screw conveyors that's also CEMA approved will adhere to these standards and have the calculations and guidelines readily available. When considering flow rate, for instance, the material conveyed (measured in cubic feet per hour) and the hanger bearing (used inside to support the screw) are the main concerns.
Cement screw conveyors are used by a range of industries, including concrete, food processing, petroleum refining, and wastewater treatment to name a few. Look to different manufacturers to find one that sells what your industry needs. From standard screw conveyors to twin screw conveyors for heavier-duty action, the right conveyor for you is out there.
