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.

Over the years, several different types of conveyor systems have been designed and are in use. The mode of working in the various types of conveying systems is different. As such, the suitability of a conveyor system in a given application usually depends on the kind of work it is meant to do. How the system works will determine in huge part how it is applied.

Despite the fact that different kinds of conveying systems are made differently, these systems share some common basic components. Most of the conveyor designs have a frame which provides support to rollers, wheels, and belts which move materials. Additionally, conveyor systems are powered through a number of ways. Among the mechanisms used to power them are gravity, using a motor, and 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.

Maximum load per unit length of a machine is the first specification one should consider. This specification normally specifies the amount of material which can be transported on the conveyor per unit length. In case the weight is exceeded, the system can be damaged. This value is normally written in the manual provided by the manufacturer or indicated on the device itself. The load capacity is closely associated with the maximum load per unit length.

Another useful specification to learn about is the belt speed also referred to as the rated speed. The units used to describe the rated speed usually depend on the type of system being discussed. In the case of screw and belt conveyors, the speed is calculated in feet per minute. This speed specifies the distance that the material can be moved per unit 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.

The frame configuration is another useful specification to know about when buying a conveyor. Frames can be designed to be curved, straight, or shaped like the letter Z. Where the drive mechanism is located on the system is also an important consideration. The drive mechanism may be located at the discharge end of the system or in the center. In rare cases, it may be found at the end where materials are fed into the system.
