Use of Conveyors for material transfer in Industries is popular from centuries. It is an easy and convenient way of moving stuff from one place to the other. In various production units, conveyors are an integral part of the manufacturing process. The technology has greatly evolved over years from mechanically controlled conveyors to sophisticated and intelligent pneumatic controlled conveyors of modern industrial units. However, mechanical controllers are still widely used. Among various mechanical versions, screw conveyors are most versatile and cost-effective. They are ideal for dry material movement. Due to relatively simple design and less maintenance, it is a popular choice. How does it work? A screw conveyor has a screw mounted on a tubular housing or U-shaped trough. There are one or more sections with a flight mounted on a pipe. Bearings are installed at both ends of the trough so that the screw can be supported. One end of the screw is connected to a drive shaft that rotates, and the other end is connected to an end shaft. In long conveyors, hanger bearings are installed for a better support. They are suspended from the top of the trough and connected to the screw between two sections. A screw conveyor is among the popular Conveyors for material transfer in Industries because it can deliver material from a single or multiple inlet locations to a single or multiple discharge locations. It can move material horizontally, vertically or even in an inclined direction without any trouble. It is capable of delivering challenging dry items in bulk quantities. It is available in a variety of configurations. Hence, one must choose the right construction material and components while deciding a screw conveyor. Choose the right conveyor based on product category Product category is an important factor while deciding Conveyors for material transfer in Industries. · Free-flowing material: Material that is solid but flows freely like liquid while mechanically agitated needs a large diameter screw and short pitch (it means the distance between two flights should be less). It regulates the flow of the material. Run it with a slow speed. Cement, powdered cocoa, skimmed milk powder and fly ash are a few examples of free-flowing material. · Non-free-flowing material: Viscous or sticky material gets accumulated in the joints of the flight surface. Hence, use a single-flight ribbon screw or shaft less screw so that there is no accumulation. Talk to the engineering department of the supplier and explain your requirement precisely. It helps in deciding the right choice of conveyor. The conveyor systems are the important elements of any industries for the transfer of goods within the plant. The conveyors can save lots of man power and time.
