In aerated concrete equipment , ball mill is mainly used limestone, gypsum, sand , slag and other materials grinding . Only these equipment and materials after grinding . Stir before they can be mixed . Only those of the mixed concrete is consistent with the standard of work . Aerated concrete crushing in a mill is an important process , it is the largest energy consuming work of one machine .Ball mill is a simplified level depend simplified , hollow shaft and abrasive material consisted of a long cylindrical simplified , grinding cylinders, bottles made of steel , coated steel and simplify outer sleeve , steel grinding balls systems in general , depending on the diameter, the load certain proportion of the role of steel may be different, which can be used abrasive particle size , the material of the fuel from the hollow shaft end of the cylinder , energy ball mill grinding plant simplified rotates due to inertia and centrifugal force , the effects of friction , which is in close proximity cylinder cylinder leave taken a certain height , because of its own weight , the ball selection switch , the height of the object to fall due centripetal force , to achieve the crushing effect.
Ball Mill in the process of turning , grinding media have dropped the phenomenon of process in the fall material to abrasive action , in order to effectively use abrasive , the mill body plate cylinder with a compartment separated as Sec , becomes two-position the material into the first position when the ball was crushed , the material into a second position when the steel side of the material for grinding, grinding the material passing from the discharge end of the hollow shaft is discharged , the feed material for grinding small particles time , such as sand on the 2nd slag, coarse fly ash, mill shell or not to set partitions, a single- chamber tube mill .
