Description

Technical Field

[0001] The present application relates to the technical field of ball mills, and in particular to a mobile feeding mechanism for ball mills. Background Art

[0002] Ceramic balls are precision ceramic products, usually made of high-purity ceramic materials, with a variety of industrial applications. The basic process flow of ceramic ball processing is: first, the ball blank is prepared by different molding techniques, and the ball blank is sintered after molding. The sintered ceramic ball needs to be machined to achieve the required size and shape accuracy. Usually including rough grinding, fine grinding and super fine grinding steps. Grinding is a very important step in ceramic ball processing, which is used to remove surface irregularities and improve the roundness and surface finish of the sphere.

[0003] The commonly used grinding tool is the ball mill. The existing ball mill is Figure 1 , including a fixed disk at the top and a grinding disk at the bottom of the fixed disk, the fixed disk has a fan-shaped opening, and the grinding disk has multiple annular channels. The grinding disk rotates at high speed, bringing the ceramic particles from the fan-shaped opening into the gap between the channel and the fixed disk to grind the ceramic particles. After the ceramic particles are brought out from the other end of the fan-shaped opening, the grinding is completed once, and then the ceramic particles will be repeatedly brought into the gap between the channel and the fixed disk for grinding until the size of the ceramic particles meets the requirements.

[0004] The ceramic particles are repeatedly polished under the drive of the grinding disc, and continue to move in a circular motion relative to the fixed disc. The grinding efficiency of the ball mill depends on the number of ceramic particles on the grinding disc. The more ceramic particles that are polished at the same time, the higher the efficiency. The original grinding disc has a limited size, and the number of particles that can be polished at the same time is limited. If too many ceramic particles are added, they will accumulate at the fan-shaped opening of the fixed disc, causing congestion or even being bounced off. In the prior art, baffles are added to prevent too many ceramic particles from blocking the channel. However, the number of ceramic particles in one grinding process is still limited by the size of the grinding disc, and the number of ceramic particles circulating at the same time is small, and the efficiency is low, so further improvement is needed.
