Ball Mill

Ball Mills are primarily used for fine grinding. Ball Mill is key equipment which repulverises the material after it is crushed. Ball Mill is widely used in powder-making production line including cement, silicate, new-type building material, refractory material, fertilizer, ore dressing of ferrous metal and non-ferrous metal, glass ceramics, etc. Our company has been amongst the pioneers for many years in the design and application of milling systems for the size reduction of a wide variety of materials including minerals, ores, and coal. There are two kinds of ball mill, grate type and overfall types due to different ways of discharging material.

Features:
1.Traditional sliding bearings are replaced by double row roller bearings in small and medium size ball mills to reduce energy consuming
2.Large ball mills adopt pitot pressure or hydrostatic bearings.
3.Air clutch system for starting the motor safely
4.Alternative synchronous or asynchronous motor
5.Low speed driving unit with Lifting device, convenient for maintenance.
6.New Endurable wearing parts to increase service life of vulnerable parts.
7.Alternative PLC automatic control system Optional Accessories ( drum sieve, Hydraulic wrench mobile feeding settings)

Working principle:
The ball mill is a horizontal rotating device transmitted by the outer gear. The materials are transferred to the grinding chamber through the quill shaft uniformly. There are ladder liner and ripple liner and different specifications of steel balls in the chamber. The centrifugal force caused by rotation of barrel brings the steel balls to a certain height and impact and grind the materials. The ground materials are discharged through the discharging board thus the grinding process is finished.
