Sand washing machines require maintenance, which means it's necessary regardless of the extreme heat or cold, in other words, it's akin to the preheating stage.

We all know that machines need to be preheated before they can start working. The working principle of the sand washing machine is actually like this:## The material enters the sand washing machine through the feed hopper and is divided into two parts by the distributor. One part enters the rotating impeller from the middle, where it is accelerated to a speed that can reach the acceleration due to gravity. It is then impacted against the material lining, sloping upwards towards the top of the vortex chamber, and changes its direction, moving downwards at an angle. The material emitted from the impeller forms a continuous curtain. In this way, the material is subjected to two or more impacts, abrasions, and crushing actions within the vortex crushing chamber. The crushed material is discharged through the lower discharge outlet. Throughout the crushing process, it does not come into direct contact with metallic components but is impacted and abraded by the material lining, thereby粉碎ing, which reduces angular contamination and extends the mechanical wear time. The vortex chamber features a clever airflow self-circulation.
