Description
Dry ball mills
Introduction:The ball mill is a key equipment for regrinding. It is widely used for the cement, the silicate product, new type building material, fire-proof material, chemical fertilizer, black and non-ferrous metal, glass, ceramics and etc. Capacity range from 1-130 tph, final product can reach to 500 mesh ! Our ball mill can grind ore or other materials that can be grin

Structure and composition
|
Ball mill is mainly composed of feeding, feeding, main bearing, cylinder, transmission department, delivery department and the main motor and other parts.
 |
Performance characteristics
|
1. Save energy: bush bearing is replaced by rolling bearing, friction resistance being greatly lowered down, easy to be started. It’s energy is lower 10-15% than the old one.
2. Large capacity: for the outlet disk and the checked liner are adopted, the capacity is higher 20% than the cone ball mill.
3. The discharging port slurry surface is low, slurry flow through rapidly, decrease ore over-grinding.
4. Load of ball is large, big balls, small balls be loaded in, and small balls can’t be discharged, and can form good working conditions.

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 Ball mill grinds material by rotating a cylinder with a steel grinding ball, causing the ball to fall back into the cylinder and onto the material to be grinded. The rotation speed is usually from 4 to 20 revolutions per minute, depending on the diameter of the mill. The larger the diameter, the slower the rotation. If the circular speed of the mill is too high, it will start to act like a centrifuge, and the ball will not fall, but stay around the mill. The point at which a mill becomes a centrifuge is called the "critical speed," and ball mills typically operate at 65 to 75 percent of that critical speed. |
