Never Do like this, or Screw Conveyor will be Scrap Iron

Never Do like this, or Screw Conveyor will be Scrap Iron

Are you still complaining about your screw conveyor? So do you still think you buy a inferior machine? After having read this article, I believe you will change your mind. Based on our survey, we have found that many users adopt wrong operation method, it will not only damage screw conveyor, but also harm person safety of operators. Therefore we hope you can adopt right operation way.

Wrong operations are as follows:

1.Open the upper cover during operation

It’s forbidden that open upper cover during operation even if in order to observe the running conditions. If there are foreign bodies falling into screw conveyor, it will damage the screw blade, shaft and casing.

2.Doesn’t clean the rested material after having used screw conveyor

If the rested materials has property of stickness and corrosion, they will corrode screw blade and shaft as well as shorten conveyor lifespan.

3.Much overload on motor

This kind of situation will cause motor has high temperature even damage motor. Thus please strictly control feeding quantity.

4.Seldom add lubricating oil into bearing

Dust will make lubricating oil thickness so that can influence the rotation of shaft. Please add lubrication oil timely.

5.Force to stop screw shaft rotating after turning off machine

It’s very dangerous to do like this, otherwise it will make a great damage on screw shaft and motor. Therefore, we should make the machine stop naturally.

Why does Screw Conveyor Occur Material Backflow

Why does Screw Conveyor Occur Material Backflow

As we all know, screw conveyor has widely application in various industries, such as building materials, chemicals, power, metallurgy, coal carbon, food and other industries, and could be suitable for horizontal or inclined conveying. During operation of screw conveyor, once there are materials blocked in hanging bearing, which is called material backflow. If screw conveyor always occurs the phenomenon of backflow, then it will cause screw conveyor throughput greatly decrease. With regard to large capacity screw conveyor, the material backed flow is likely to undermine reducer, and result in reducer overburn as well as economic losses.

If it is seen from transportation process of screw conveyor, the speed of controller and slipping material determines the speed of material which is conveyed from screw conveyor. What’s more, conveyor filling coefficient determines the discharge time, and the speed is large or small depends on the size of screw arbor and motor. Therefore raise these two components size can successfully address the material backflow problem.
