Useful And Essential Facts About Screw Conveyors

By Diane Perry


Conveyor systems refer to mechanical devices that are used to transport materials from one point to another. They are heavily used in production plants and other settings where materials are handled in bulk. These systems are used a lot because they require minimal effort to move materials. This helps to save time and effort that would be involved in the process of moving materials around. Here are facts regarding Screw Conveyors.

Conveyors of different kinds have been manufactured over the years. This means that the available conveyors also vary in the way that they work. Therefore, the kind of work that a conveyor is designed to perform determines its suitability to be used in certain applications. The application of a conveyor system greatly depends on how it works.

Some basic parts of conveying systems tend to remain the same even though conveying systems differ in design. One of the features that is common among conveyor systems is the frame. The frame supports the belt, wheels, and rollers that move the materials. Another common feature is that different means are used to power the systems. The powering can either be through gravity, a motor, or manual means.

The kind of conveyor system to be used may be determined by the kind of material being moved. It can also be influenced by the working environment of the machine. One should have several factors properly considered before purchasing a conveyor system. For instance, one needs to consider the specifications of the system.

The first specification to consider should be the load capacity per unit length of the machine. This specification specifies the amount of load that should be transported on the system per unit length. Exceeding this capacity will usually damage the system. This value is usually indicated on the device or in the manufacturer manual that comes with it. Closely related to the load capacity per unit length is the maximum load capacity.

The rated speed also known as the belt speed, is another important specification that one should learn about. The system being discussed will determine the units that will be used to describe the rated speed. The speed is normally calculated in feet per minute when dealing with screw or belt conveyors. This speed normally specifies the material that can be moved over a certain duration of time

Since screw conveying systems handle powdered materials and other bulk materials, it usually has a specified throughput. The throughput is usually calculated in volume per unit time. For instance, the throughput can be specified in form of cubic feet per minute. Besides screw conveying systems, there are also other types of conveying systems that have the throughput value specified. These include walking beam, vibrating, vacuum, and bucket conveying systems.

It is also important to check the frame configuration of a conveyor before purchasing it. The frames are normally straight, curved or at terms they can be in the shape of the letter Z. Similarly, the location of the drive mechanism is important to consider. This is usually at the center or at the rear end of the system in most cases. It can also be located at the end where materials get fed onto the conveyor although this configuration is very rare.
