Product Description

MQY1557 cement clinker ball mill machine
Ball mill introduction

Gold ore grinding ball mill drive adopts large double-row spherical roller bearings instead of sliding bearings, which greatly reduces friction, easy to start, and saves 20%-30% of energy. The corrugated liner is used in the cylinder of the ball mill to increase the contact area of the ball ore and strengthen the grinding effect. At the same time, it has the ability to improve the ore, further reducing energy consumption. The energy-saving beneficiation ball mill has a large discharge port, which greatly improves the production capacity. The lubrication system uses an oil mist lubrication device to ensure reliable lubrication of gears and gears.

The liner of the beneficiation ball mill is made of high manganese steel, high chromium cast iron, rubber, etc. The thickness is up to 50-130mm, and there is a gap of 10-14mm between the liner and the shell. Plywood, asbestos pad, plastic board or rubber can be used to lay it on the shell, the purpose is to cushion the impact of the steel ball on the cylinder. The liner is fixed on the cylinder by bolts. In order to prevent the slurry from leaking out, there are rubber rings and metal washers under the nut. The liner can be divided into smooth and non-smooth according to the surface shape. The uneven liner can raise the grinding medium to a higher height and then fall, so that the impact of the steel ball on the ore is strengthened. The smooth liner has a relatively large relative sliding between the steel ball and the liner, so the steel ball has a strong grinding effect on the ore, so it is often used for fine grinding.
Working principle of mineral ball mill: The mineral ball mill is a horizontal cylindrical rotating device with outer gear transmission, and a grid type energy-saving ball mill. The material enters the cylinder of the mill uniformly through the feeding device through the hollow shaft of the feeding device. The cylinder has corrugated liner, which contains steel balls of different size. The rotation of the cylinder generates centrifugal force to bring the steel balls to a certain height. After falling, it has a heavy blow and grinding effect on the material.
Structural features of mineral ball mill: The mineral ball mill is composed of feeding part, discharging part, rotating part, transmission part (reducer, small transmission gear, motor, electric control) and other main parts. The hollow shaft is made of cast steel, and the inner lining is removable. The large rotary gear is processed by casting gear hobbing. The cylinder is inlaid with a wear-resistant liner, which has good wear resistance. The machine runs smoothly and works reliably.
