AI Technical Summary
In the existing crushing equipment, the coated sand at the bottom of the crushing tank adheres to the sand during the crushing process, making it difficult to crush and resulting in incomplete crushing. The sand also tends to stick to the inner wall, increasing the probability of needing to be crushed again.
A coated sand circulating crushing device was designed, which adopts a structure of rotating drum, flip plate, grinding wheel and stirring rod. The flip plate is driven by a drive motor to scrape off the coated sand on the inner wall, and the sand is finely ground by the grinding wheel and stirring rod. A collection structure is added to prevent splashing.
It achieves complete crushing of coated sand, avoids adhesion to the inner wall, improves crushing efficiency, and prevents coated sand from splashing through the collection structure.
