Cement Mill

Applications:

Cement Ball mill is used to grind many kinds of mine and other materials, or to select the mine.Ball Mill grinds material by rotating a cylinder with steel grinding balls, causing the balls to fall back into the cylinder and onto the material to be ground. The rotation is usually between 4 to 20 revolutions per minute, depending upon the diameter of the mill. The larger the diameter, the slower the rotation. If the peripheral speed of the mill is too great, it begins to act like a centrifuge and the balls do not fall back, but stay on the perimeter of the mill. The point where the mill becomes a centrifuge is called the Critical Speed", and ball mills usually operate at 65% to 75% of the critical speed.

Features:

(1)Newest structure, saving energy
(2) Easy maintenance and operation
(3) Durable wearing parts
(4) Low operating cost
(5) Big and fine grinding ratio
(6) Whole base support, easy to installation
(7) Special design, saving energy about 30%
(8) Longer minning service life
(9) Improve fineness of discharging

Working principle:

The cement 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.
