Product Description

The large gear installed on the end cover of the ball mill, also called the large ring gear, is generally divided into three types: full ring gear, half ring gear, and quarter ring gear. This large ring gear is called the ball mill large gear.

The large gear of the ball mill is located in the rotating part of the ball mill. It meshes with the small gear and transmits power to the ball cylinder through the transmission shaft to drive it to rotate. The large gear of the ball mill bears large torque and axial force, so its quality and strength are crucial. If there is a problem with the large gear of the ball mill, the ball cylinder may not rotate normally, which will affect production efficiency and product quality.

Product Performance

  • 1High transmission efficiency

    The large gear of the ball mill is composed of many gears. It has a compact structure and high transmission efficiency, which can effectively transmit the power of the motor to the entire Ball mill equipment.

  • 2 Large number

    The large gear of the ball mill is composed of multiple gears. The number is usually between 20-50. Each gear is spaced at a certain distance. Distributed on the wheel circle to evenly share the transmission load.

  • 3Complex structure

    In addition to multiple gears, the ball mill gear also includes bearings, bearing seats, couplings and other components. The structure is relatively complex, and the coordination between various components needs to be considered to ensure the normal operation of the entire machine.

Working Principle

Horizontal cylindrical rotating device, outer gear transmission, two chambers, grid-type ball mill. The material enters the first chamber of the mill evenly and spirally from the feeding device through the feeding hollow shaft. There are ladder linings or corrugated linings in the chamber, and steel balls of different specifications are installed inside. The rotation of the cylinder generates centrifugal force to bring the steel balls to a certain height. Then it falls, causing heavy impact and grinding effect on the material. After the materials reach coarse grinding in the first chamber, they enter the second chamber through the single-layer partition plate. This chamber is equipped with a flat lining plate and contains steel balls for further grinding the materials. The powdery material is discharged through the discharge grate plate to complete the grinding operation.
