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.

​►Our company was founded in 1971 and has a history of more than 40 years. Rich experience and strong strength are the primary guarantee for equipment quality and after-sales service.

►We are located in the triangle of Beijing, Tianjin and Tang, with superior geographical location and convenient transportation. It is 180 kilometers away from Tianjin Port (3 hours by car) and can guarantee timely delivery.

►Choose excellent raw materials. The steel materials are selected from well-known domestic manufacturers as suppliers to fully guarantee the chemical composition of the raw materials and the mechanical properties of the equipment.

►Strict product testing. Welding is submerged arc welding, and each weld is inspected by a flaw detector (ultrasonic

flaw detection). After passing the test, it will continue to the next process.

►After each equipment is completed, it will be installed and run in the factory to ensure stable operation of the equipment before it is loaded and shipped.
After heat treatment, the casting spare parts are machined in our factory for processing. After processing, the quality inspection department will conduct quality inspection and flaw detection.
