Description

The working principle of the slurry grinding machine is to achieve the grinding effect through mutual extrusion of the surfaces of multiple horizontally arranged rollers and friction of different speeds. At present, the three-roller grinding machine is the most effective grinding and dispersing grinding equipment for slurry. According to the search, the patent document with the authorization announcement number CN215996806U discloses an automatic feeding device of a three-roller grinding machine, which comprises a feeding tank, a track box and a grinding machine.

A limiting plate is fixedly connected to one side of the feeding tank. A push rod is fixedly connected to the bottom of the push plate. A limiting sleeve is inserted into one end of the push rod. A spring is arranged in the limiting sleeve. When in use, the object to be ground is placed in the feeding tank. The spring is extruded forward according to its elasticity, so that the push plate plays a pushing role. The object falls into the grinding machine from the leakage hole. The push plate continues to push forward, so that the automatic feeding work is completed, time and labor are saved, the danger of the traditional method is avoided, and the working efficiency of the device is greatly improved
