In summary, the chemical grinding equipment with differential rotation and self-deceleration during uncovering is characterized in that the middle of the shell 1 is rotatably connected with the first rotating shaft 201, the motor 202 is started, the second rotating shaft 204 synchronously rotates under the transmission of the bevel gear set 203, the first rotating shaft 205 and the second rotating shaft 208 are matched for transmission, the bottom grinding disc 206 and the top grinding disc 209 rotate in the same direction and differentially grind raw materials, the cam 36 rotates to jack the right support 212 based on the transmission of the two-way joint 37, the top grinding disc 209 moves up and down in a reciprocating manner, the surface of the same layer of raw materials is prevented from being simultaneously ground, the floating differential rotation grinding effect is achieved, the surface of the grinding roller is prevented from stopping due to the blockage of the raw materials, and the grinding effect of the raw materials is improved

In addition, the differential rotation and cover opening self-deceleration chemical grinding equipment is characterized in that the limiting frame 31 is fixedly connected to the right end of the bottom of the shell 1, when powdery raw materials are taken out, the motor 202 is turned off, at the moment, the bottom grinding disc 206 and the top grinding disc 209 continue to rotate due to inertia, the top grinding disc 209 is separated from the inside of the bottom grinding disc 206 by the aid of the lifting pull rod 35, the sliding block 34 continues to move upwards by the aid of the lifting pull rod 35, the stop block 32 moves leftwards to abut against the right side surface of the cam 36 under the transmission of the groove rod 33, the rotation resistance of the cam 36 is increased, the rotating speed of the first rotating shaft 201 is reduced under the transmission of the bidirectional joint 37, the automatic deceleration effect during the lifting is achieved, the time spent on waiting for the rotation stop of the grinding roller is reduced, and the grinding efficiency is improved.
