The design of a ball mill can vary significantly depending on the size, the equipment used to load the starting material (feeders), and the system for discharging the output product. the size of a mill is usually characterized by the ratio “length to diameter” and this ratio most frequently varies from 0.5 to 3.5..
The efficiency of the mill to break ore is a function of both the feed size distribution and the relative hardness of the ore. when the feed size of a sag mill becomes coarser, i.e. α r increases.
The mixed ores are crushed further and copper and molybdenum ore are separated. the separated ore will finally become concentrates after processes of concentration, filtering and drying. in the design of ball milling process, the grinding stages are commonly decided by the dissemination size of useful minerals in raw.
The rotation of the cylinder causes the balls and minerals to remain in constant impact that slowly wears the mineral to a specific size or powder ratio. ball milling is used in the processing of ceramics, paints, coal, pigments, feldspar, and more. in addition to grinding minerals down, a ball miller is often used to mix or blend.
The sheer size and scale of new ore processing operations, with their associated desire to substantially increase product throughput, means that primary sag mills have grown to larger capacities. paul peng, ceo and chief metallurgist at sino grinding industries (sgi), emphasizes it is critical that grinding media is designed and manufactured to cope with this.
