[0022] It should be noted that traditional crushing devices for chemical production often use a fixed feeding system, which cannot be flexibly adjusted according to the characteristics of the raw materials and production needs. This leads to the following problems in the actual production process: On the one hand, when the feed volume is too large, the crushing device may not be able to crush all the raw materials in a timely and sufficient manner, resulting in insufficient crushing, or even blockage or overload. This not only affects the crushing efficiency, but may also cause damage to the device itself; on the other hand, when the feed volume is too small, the crushing capacity of the crushing device cannot be fully utilized, resulting in low production efficiency; at the same time, too small a feed volume may also cause uneven particle size distribution of the crushed material, which cannot meet production requirements; therefore, in order to solve the above problems and improve the performance and adaptability of crushing devices for chemical production, the utility model proposes an adjustable crushing device for chemical production;
