1 to 15 TPH Small Scale Miners Ball Mill. Our small-scale miners Ball Mills use horizontal rotating cylinders that contain the grinding media and the particles to be broken. The mass moves up the wall of the cylinder as it rotates and falls back into the toe of the mill when the force of gravity exceeds friction and centrifugal forces. Particles are broken in the toe of the mill when caught in the collisions between

The fine ore passes through an open circuit 2.7 x 3.8-metre rod mill and a 3.8 x 4.7-m ball mill in closed circuit with cyclones to produce a grind of 85 passing 200 mesh. Grinding circuit underflow is pumped to two Knelson concentrators then passed over a shaking table to recover the free gold.
Ball Mills. Ball mills have been the primary piece of machinery in traditional hard rock grinding circuits for 100 years. They are proven workhorses with discharge mesh sizes from ~40M to 200M. Use of a ball mill is the best choice when long term stationary milling is justified by an operation. Sold individually or as part of our turn-key ore processing system.
