[0002] Lithium-ion batteries are rechargeable batteries that can be used multiple times. They transmit electricity through the movement of lithium ions between the positive and negative electrodes. Most of these materials are organic electrolytes. In order to prevent leakage from the battery pack, it is necessary to add packaging protection to the outside of the electrolyte. The general coating materials are mostly insulating materials such as rubber. During processing, various materials need to be crushed and refined and then put into the mixer for heating and melting. However, such equipment in the past often only has a single chamber for processing. Some materials begin to mix before they have time to be refined, which is very inconvenient.

[0014] (1) The raw materials are put into the two component tanks through the notches on the sides of the partition top by welding the sub-tanks on both sides. The motor is started, and the motor fixed at the bottom guides the large toothed disc to mesh with the small toothed discs on both sides to rotate, forcing the crushing shaft in the sub-tank to crush the materials inside.
