30 Tph Gold Ore Ball Mill For Mineral Processing Plant

The raw material is fed into the hollow cylinder through the hollow journal for grinding, and the cylinder is equipped with various diameters of grinding media (steel balls, steel rods or gravel, etc.). When the cylinder rotates around the horizontal axis at a certain speed, under the action of centrifugal force and friction, the medium and raw materials in the cylinder will leave the cylinder when the gravity is greater than the centrifugal force when the cylinder reaches a certain height. The internal wall projectile falls or rolls down, crushing the ore due to the impact. At the same time, during the rotation of the mill, the sliding movement between the grinding media also produces a grinding effect on the raw materials. The ground material is discharged through the hollow journal.

Ball Mill:
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.
