Causes of blade failure of screw sand washing machine

2019-03-12

Screw sand washing machine, also known as spiral stone washing machine, is usually used in the sand machine production line, our common spiral sand washing machine is a kind of sand washing equipment, when we use in the process of the blade failure, so what is the reason, today by LZZG to explain causes of blade failure of screw sand washing machine for you.

Blade abrasion failure

This is a very common phenomenon of sand washing equipment, usually the reason for blade wear is mainly caused by long-term grinding of materials and strong impact force, especially for some often used for grinding the larger size of ore sand washing machine, its wear speed is faster.Wear on the blade surface will cause its size to decrease until it no longer meets the normal production requirements of the sand washer.

Brittle failure of blades.

There are three reasons for the occurrence of this kind of screw sand washing machine blade :(1) Sand washing equipment will also be subject to external force and material caused by the temperature change, resulting in the spiral sand washing machine blade internal stress is constantly increased, will eventually cause the carbide crack phenomenon.

(2) When the screw sand washing machine uses heat treatment to process the casting, it often produces some tiny cracks on the surface. When the cracks are constantly expanded, it will cause the failure of the blade.

(3) If the screw sand washing machine is stuck by metal objects such as bolts in the process of work, the sand washing machine will generate a greater force and thus brittle failure.

The above is on the spiral sand washing machine these two kinds of blade failure to make some simple introduction we hope to help you.However, you should pay attention to the sand production line, whether it is sand washing equipment or sand making equipment, you need to carry out maintenance and maintenance in the daily work, if there is a problem should be resolved in time.
