Profile

The ball mill is the device that uses grinding ore and other materials to produce satisfactory product particies, and the ball mill designed and manufactured by our company has been widely used in industries like metallurgy, mine, building materials and chemicals domestically and internationally.

The ball mill is mainly composed of the feeding part, charging part, main bearing, tank part, drive part, discharge part and the main motor, The motor drives the body of the ball mill through drive and deceleration of the gear pair to ore grinding medium within the body at the proper rotate speed. Under the function of centrifugal force, friction force and gravity, the motor is raised to certain height and then falls in the state of throwing-up or faling, when materials , within the body are crushed under the impact effect. Meanwhile, due to medium rolling or sliding, materials are grinded under the gringding effect. Grinding materials are ejected from the discharge gate. Upon demands, the ball mill can be equipped with the air clutch, low-speed driving device, jacking device, jet lubrication device and the like. The main bearing of the ball mill can adopt ordinary sliding bearing, hybrid bearing, hydro-static bearing and anti-friction bearing upon demands.

The ball milt can adopt magnetic liner plate as required , its features in thinner liner plate, lighter weight and longer service life compared with that of the metal liner plate, which can reduce energy consumption and improve output, The magnetic liner plate is generally applicable to two-stage process mil. Öur company can design and manufacture ball mils of various applications and specifications as required by users.

Working Principle

This machine is a horizontal type cylinder rotary device and outside the cylinder there is drive gear which drives the cylinder to rotate during the working process. Materials spirally and evenly go into the first cabin of the grinding machine through the feeding hollow shaft from the feeding device, and inside the first cabin, there are ladder lining boards or ripple lining board in which there are many steel balls with different specifications. The cylinder rotates and produces eccentric force to bring the steel balls to a certain height, and then the steel balls will fall down to impact and grind the materials. After being coarsely ground in the first cabin, the materials will go through the single-layer partition board and into the secondary cabin in which there are flat lining board, and in the lining board there are steel balls to further grind the materials. Finally the powdery materials will be discharged from the discharging grating bar to complete the powder grinding process.
