Advantages Of Using Screw Conveyors

By Kenneth Olson


Many years professionals have accumulated enough experience in designing tools to perform various tasks depending on the work to be done. The design and application of the screw conveyors has led to the refinement of the best conveyor design. One should keep in mind how to calculate the speed, size and the required power with the minimum mathematical calculations as much as possible.

Horizontal conveyor is the mostly used type of this tool. They are used to carry one bulk from one process to the other and comes in different sizes and length. It also ranges on the material of construction and also configurations. They are controlled by other devices such as screw feeder and, rotary air clock and volumetric feeder.

Horizontal conveyor is designed to perform task of 15, 30 or 45 degrees of the loading when incorporated with other devices. Each session should be put in tension as the bulk materials is carried to the other end to reduce the wear and fatigue of the tool. The advantage of using this machine is that it is cost effective and less hazardous to the environment because it is totally enclosed from dusty.

Inclined machine is another type of tool in this category. They operate in a slightly more that horizontal position, this means the bulk should be not inclined less than 45 degree. The machine should be incline to 10 degree from the horizontal position. In some cases it can be adjusted to between 10 to 15 degrees to perform other functions. This machine is highly efficient because of the position of the pitch.

The conveyor can also be sealed to avoid dusty. The dusty or fumes will not enter into the tool thus avoiding the possibility of wear and tear. This tool is also friendly to the environment because it is usually in the closed seal such there is no vapor released to the environment. They can also be utilized by using it either horizontally, vertically or inclined.

Other important step is to check the torsional ratings of the components. These type of tolls are always limited to the in the overall size and length and the amount of torque should be safely transmitted through the selected components. One should increase the revolution per minute of the component in orders to acquire the smaller and inexpensive tool. The cost and design is the important variables should be considered.

The last step involves checking the shaft end angle, abrasion, and the screw deflection and conveyors thermal expansion. All the features should be checked before completing the task of the tool. The shaft end angle and the deflection should be directly proportional to the tool useful life. Also the screw conveyor should also be able to convey hot or cold materials. The screw and the trough expand and contract at the different rate.

Therefore, it is advisable to choose the correct tool depending on the work one is handling to avoid low efficiency. Tools have specific function especially the screw conveyor and should not be mistakes, the feature are seemingly the same thus prone to confusion. Each tool has its own configurations and different horse power.
