If the material hardness over limited, even harder than the material to build the grinding mill, which will definitely increase the wear rate of the grinding mill, and resulting in some parts of early retirement, more harm than good. Users should also refer to the process of using manual stone grinding machine operating at a reasonable working environment. 
 

      Also, if some of the more difficult materials which contain contamination of ground where it can not be crushed in the grinding mill interior circulation is bound to continue to accelerate the wear rate of the grinding parts. Therefore, before feeding the material must be screened to weed out the impurities. 
 

      It must adapt the best quality steel to produce grinding mill ring and roller because inferior steel to build the parts wear faster, the user may use 1-2 months to go before its replacement, which will inevitably result in property damage users . Manganese is to create the most suitable steel mill wearing parts, good performance milling equipment currently in use. 
 

      As long as noticed these points, we can effectively reduce the speed grinding mill parts wear, greatly extend the life of stone grinding machine. Not only to reduce the frequency of replacement of wearing parts, but also bring economic benefits to the user directly. If any question of grinding mill, please feel free to contact me.
