Some of the conclusions drawn from this test are that: (a) The ballmill is naturally a machine of very large capacity; (b) if it is not possible to deliver a large tonnage of original feed to the mill, a closed circuit should be provided so that the mill may crush its own oversize. Closed Circuit Grinding
WhatsApp: +86 18838072829There are many types of flow sheets in use today. The tendency in new mills is to crush relatively fine (¾ to ½ in.). Singlestage ball mills in closed circuit with classifiers are used for grinds coarser than 48 mesh, but when a finer product is desired, two stages of ball mills in closed circuit with classifiers is usual.
WhatsApp: +86 18838072829The spiral classifier is based on the principle that the size of the solid particles and the specific gravity are different, so the sedimentation speed in the liquid is different. It is a kind of grading equipment that is pushed up by the screw and discharged to the top for mechanical grading. It can grade the powder in the mill for filtration ...

WhatsApp: +86 18838072829A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.
WhatsApp: +86 18838072829Very large tonnages can be ground with these ball mills because they are very effective material handling devices. Ball mills are rated by power rather than capacity. Today the largest ball mill in operation is m diameter and m long with a corresponding motor power of 22 MW (Toromocho, private communications).
WhatsApp: +86 18838072829The grinding process in ball mills and vertical roller mills is fundamentally different [15]. Following are advantages of VRM over Ball Mills with reference to these issues: • Strong drying ability Inlet hot air from Kiln can dry materials with 20% water content. (max moisture 20% vs. 3% in ball mill) [15], [16]. •
