[0031] The use method of this utility model:
[0032] First of all, it should be made clear that the grinding device involved in the present invention is mainly used for grinding materials. The present invention takes the grinding of aluminum coatings, such as polyurethane block materials, as an example to explain its method of use in detail. When the material needs to be ground, the output shaft of the motor is started to rotate. The rotation of the output shaft of the motor drives the grinding rod 210 to rotate together with the fixed disk 231, the telescopic sleeve 232 outside the fixed disk 231, and the grinding balls 233 of different diameters outside the telescopic sleeve 232.

The stretched spring will stretch and retract reciprocatingly under the action of its own restoring elastic force. , thereby realizing the impact crushing operation of the material between the grinding balls 233 and the inner wall of the filter barrel 234, and the grinding effect is better. The ground material smaller than the aperture of the filter mesh of the filter barrel 234 will fall through the filter mesh and be ground by the next-stage grinding component 230. The utility model can realize the full and efficient grinding operation of the to-be-ground material of different particle sizes in the barrel body 101 through the multi-stage grinding mechanism 200 arranged in the barrel body 101, which solves the problem that the traditional grinding device can often only perform one-stage grinding during the process of grinding the paint. In the process of grinding the paint, due to the different particle sizes of the grinding materials, the grinding effect of the grinding roller is poor, and it is necessary to screen and sort the ground material and then select a grinder with different grinding particle sizes for secondary grinding operation, which has poor grinding effect, greatly reduces the grinding efficiency, and also increases the unnecessary equipment cost.
