What S The Difference Between Sag Mill And Ball Mill
mill is a grinder used to grind and blend solid or hard materials into smaller pieces by means of shear, impact and compression methods. grinding mill machine is an essential part of many industrial processes, there are mainly five types of mills to cover more than 90% materials size-reduction applications.grinding mill such as an autogenous mill or ball mill, having a large driving gear driven by two motors, wherein a soft start capability is provided by a clutch or clutches, is finger-printed in relation to the reduction gear system in order to identify optimum conditions for locking up the drive to achieve substantially equal loading between the drive motors, and to diminish cyclic flexible drive solutions for use in ball mills ball mill is a horizontal cylinder filled with steel balls or the like. this cylinder rotates around its axis and transmits the rotating effect to the balls. the material fed through the mill is crushed by the impact and ground as a result of the friction between the balls.mill type overview. three types of mill design are common. the overflow discharge mill is best suited for fine grinding to 106 microns.; the diaphram or grate discharge mill keeps coarse particles within the mill for additional grinding and typically used for grinds to 150 250 microns.; the center-periphery discharge mill has feed reporting from both ends and the
