Mining Rock Gold Ball Mill Grinder Cement Ball Mill Grinding
Machine
Working principle of ball mill:
Because the gear transmission of the ball mill will generate axial
force, a hollow shaft neck is designed with two convex shoulders,
and the distance between the convex shoulders is exactly equal to
the length of the bearing shell, so as to prevent axial movement.
The gears are driven by the motor or the cylinder is driven by the
low-speed synchronous TV through the peripheral gear transmission.
The material is loaded into the cylinder from the hollow shaft at
the feed end. When the cylinder of the ball mill rotates, the
grinding body is attached to the cylinder lining due to inertia,
centrifugal force and friction, and is carried away by the
cylinder. When it is brought to a certain height, it is thrown down
due to its own gravity. The falling grinding body crushes the
material in the cylinder like a projectile. When the material
enters the cylinder, it is crushed by the grinding medium, thus
achieving the crushing and grinding effect.
Features:
1. Simple structure, stable and reliable operation, suitable for
fine grinding and medium grinding, with good screening effect and
strong controllability.
2. The ball mill liner design adopts a grooved annular liner, which
increases the contact area between the steel ball and the ore,
strengthens the grinding effect of the steel ball on the ore, and
enhances the lifting capacity of the ore, and also achieves the
purpose of energy saving and consumption reduction,liner material
includes high manganese steel, high chromium cast iron, medium
manganese ductile iron, etc. for customers to choose.
