aug 18, 2019 In general, the ratio of ball mill ball is a complicated technical problem. each concentrator must carefully analyze its actual situation. through long-term research and accumulation, you can find the right match ratio for yourselves. besides, the ball ratio also includes the size and quantity of grinding balls. ball mill grinder
selection chart for ball grinding mill for cement. the type of mill also can affect the selection of grinding media ball mills use very large media while attritors employ media ranging in size from to horizontal mills require much smaller media, as small as mm to mm to read detailed specs and submit a quote, click here for our metallic media or here for our nonmetallic media
calculation of reduction ratio ball mill. this indicates that the rod mill reduction ratio is much larger than those at normal condition, and ball mill reduction ratio is much smaller more detailed standard number of reduction ratio of grinding mill where rro optimum reduction ratio for the mill size long and tedious and requires a standard set of grinding
It changes the grinding product fineness and even influences the grinding efficiency of ball mill. therefore, the operators of ball mill need to check the steel ball situation regularly, adding steel ball reasonably and ensuring the stable production of ball mill. 5.strictly controlling the grinding concentration of ball mill. generally, the
