Hongji Product Introduce

The ball mill is a key piece of equipment for grinding crushed materials, and it is widely used in production lines for powders such as cement, silicates, refractory material, fertilizer, glass ceramics, etc. as well as for ore dressing of both ferrous non-ferrous metals. The ball mill can grind various ores and other materials either wet or dry. There are two kinds of ball mill, grate type and overflow type due to different ways of discharging material. There are many types of grinding media suitable for use in a ball mill, each material having its own specific properties and advantages. Key properties of grinding media are size, density, hardness, and composition.

The Structure of ball mill

The machine is composed by feeding part, discharging part, turning part and driving part (reducer, small driving gear, electric motor and electric control). The quill shaft adopts cast steel part and the liner is detachable. The turning gearwheel adopts casting hobbing process and the drum is equipped with wear-resistant liner, which has good wear resistance. The machine is with stable and reliable working condition.

Working principle of ball mill

Ball Mill is a horizontal rotating device transmitted by the outer gear. There are ladder liner and ripple liner and different specifications of steel balls which are loaded according to different diameters and a certain proportion in the chamber. When processing, the materials are transferred to the grinding chamber through the quill shaft uniformly, the centrifugal force caused by rotation of barrel brings the steel balls to a certain height and impact and grind the materials into fine powder over a period of several hours. The ground materials are discharged through the discharging board thus the grinding process is finished.
