Common equipment includes jaw crusher, hammer crusher, etc. The structure of such equipment is relatively simple, the crushing process mainly depends on the single milling action of the material in the fixed crushing cavity, and the crushed material directly enters the next process, lacking further circulation processing.

[0004] Since the traditional crushing equipment does not adopt the circulating crushing mechanism, the material is directly discharged after one-time crushing, resulting in uneven particle size and difficult to meet the high-precision crushing requirement. For raw materials that need to be refined (such as water slag, etc.), it is difficult to achieve ideal particle size distribution, affecting the efficiency and quality of subsequent processing.

[0005] The traditional crushing equipment usually does not combine the material conveying function, and the crushing and conveying are carried out separately, so the overall process efficiency is low. Especially in the scene where the crushed material needs to be crushed multiple times, the traditional equipment cannot realize integrated circulating crushing, increasing the complexity of equipment configuration and operation cost.

[0006] In the prior art, since the discharge system cannot effectively control the material flow, the material often accumulates or discharges poorly, further reducing the working efficiency of the equipment and increasing the maintenance and cleaning burden. In summary, the traditional raw material crushing equipment has obvious deficiencies in crushing particle size uniformity, efficiency and integrated design, and an innovative design with circulating crushing function and realizing efficient material conveying and crushing integration is needed to improve the crushing effect and simplify the process flow.
