Ball Mill Introduction
Zenith Ball mills are widely used in various types of ores' benefication, electricity, cement and chemical industries.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 overfall 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.
Two Types Of Ball Mill
Aside from common ball mills there is a second type of ball mill called planetary ball mill Planetary ball mills and The grinding balls.
Planetary ball mills are smaller than common ball mills and mainly used in laboratories for grinding sample material down to very small sizes. A planetary ball mill consists of at least one grinding jar which is arranged eccentrically on a so-called sun wheel. The direction of movement of the sun wheel is opposite to that of the grinding jars (ratio: 1:-2 or 1:-1 or else).
The grinding balls in the grinding jars are subjected to superimposed rotational movements, the so-called Coriolis forces. The difference in speeds between the balls and grinding jars produces an interaction between frictional and impact forces, which releases high dynamic energies. The interplay between these forces produces the high and very effective degree of size reduction of the planetary ball mill.
Working Principle of Ball Mill
The ball mill is a horizontal cylindrical rotating device, with outer gears transmission, two warehouses and a grate ball mill. The materials get into the first warehouse through the feeding quill shaft from the feeding device evenly, with the step scale board or the corrugated scale board in the warehouse loaded with different sizes of steel balls. The centrifugal force produced by the rotation of the cylinder raises the steel balls to a certain height, which then fall down, thus making a thumping and abrading to the materials. The materials after coarse grinding in the first warehouse get into the second warehouse with flat scale board embedded with steel sections through the single monolayer partition panel for further crushing. The powder of the materials will be discharged from the unloading board to finish the grinding work.
Ball Mill Benefits
- Traditional sliding bearings are replaced by double row roller bearings in small and medium size ball mills to reduce energy consuming
- Large ball mills adopt pitot pressure or hydrostatic bearings.
- Air clutch system for starting the motor safely
- Alternative synchronous or asynchronous motor
- Low speed driving unit with Lifting device, convenient for maintenance.
- New Endurable wearing parts to increase service life of vulnerable parts.
- Alternative PLC automatic control system Optional Accessories ( drum sieve, Hydraulic wrench mobile feeding settings)
