Maintenance and Advantages of Screw Conveyors

Screw conveyor is widely used in building materials, chemicals, metallurgy, coal, food and other industries. The normal operation of the screw conveyor is inseparable from the daily operation and maintenance. Therefore, proper operation and timely maintenance are critical to extend the life of the equipment and increase productivity.

First, check before starting: check whether screw conveyor machine parts are tight or not; feed mouth, the outlet is smooth; reducer oil is normal. Driving sequence: first start the motor, to be normal after the operation to join the material evenly. Stop the order: first stop feeding, to be screwed material after the air and then stop the motor.

Second, often check the working status of the parts, pay attention to whether the fasteners loose, such as loose should immediately stop, so that re-fastening.

Third, pay attention to the operation of the process of abnormal sound, with or without friction rub the sound, if there should be immediately stop processing.

Fourth, after parking should carefully check the bearing wear and tear, as well as the ministry of lubrication, lack of oil to be added in time.
5, reducer winter with 30 # mechanical lubricants, summer with 45 # mechanical lubricants; hanging bearings and front and rear rolling bearings with calcium-based grease.

Advantages: simple structure, low manufacturing cost, easy maintenance, better tank insulation, multi-point feed and multi-point discharge, one screw conveyor can be transported to the two directions at the same time, in the transport process can be carried out material mixing, mixing, loose, heating and cooling process.

The screw conveyor is suitable for conveying powdery, granular, and small pieces of material. It is not suitable for conveying long fibrous, hard chunks, agglomerates and fragile materials. It is mainly used for conveying at a very low level, Inclination.
