Embodiment Construction
[0018] The process flow chart of ball mill grinding is as follows figure 1 shown. The grinding circuit of the ball mill is mainly composed of an overflow ball mill, a pump pool, a hydrocyclone classifier and other equipment. The ore enters the ball mill through the feeder, and at the same time, the feed water flows into the ball mill inlet. The ore is ground in the ball mill to form a slurry that enters the pump pool, and is lifted by the pump to the hydrocyclone classifier. Classified fine-grained pulp is sent to subsequent processes such as flotation, and the coarse-grained pulp is returned to the ball mill for grinding again.
[0019] In the present invention, the actual feeding speed is measured by a belt scale, the actual feeding water flow is measured by a flow meter, the actual feeding speed and the actual feeding water flow are controlled, and the overflow particle size of the grinding is obtained by a particle size analyzer, which is the largest in the ball mill.
