This utility model provides a pretreatment device for polyester recycling ester by-products, relating to the field of polyester recycling ester by-product treatment technology. It includes a crusher body, with multiple legs fixedly installed at the bottom. An inlet is fixedly installed at the top opening of the crusher body, and an air valve is fixedly installed at the bottom opening. A housing is fixedly installed at the bottom of the air valve, and a grinding mechanism and a striking mechanism are arranged inside the housing. In this utility model, when the crushing components of the crusher body are in operation, a transmission rod drives the grinding blocks to move. When the crushed by-products fall onto the screen plate, the grinding blocks and the screen plate cooperate to further grind and crush the by-products. Simultaneously, a clamping block follows the movement of the grinding blocks and collides with the circular holes on the screen plate, generating vibration on the screen plate, thereby facilitating the falling of the ground by-products.
