Spiral sand washer is also called spiral stone washing machine, the blades will be failure during use, then what is the reason? Now Luoyang Dahua will explain in detail from the following two causes. In fact, the blade failure reasons of spiral sand washer are divided into the followings:
Firstly, the blade abrasive of spiral sand washer is worn out.
Secondly, the brittle failure of blade. There are three reasons to lead the blade failure appeared:
(1) The sand washing equipment also will be affected by external forces and temperature changing caused by materials, which leads to the internal stress of the blades are increasing, eventually causes carbide cracked.
(2) When the spiral sand washer process on casting with the heat treatment, often produce some tiny cracks on the surface, the cracks continual extension will cause fracture failure of the blade.
(3) If the blades of sand washing machine got stuck by bolt metal objects in the process of operation, it will produce greater forces to cause brittle failure.
