Description

Technical Field

[0001] The invention relates to the technical field of sand material crushing and separation, in particular to a rotary crushing and separation device for preparing building sand material. Background Art

[0002] Sand is an indispensable and important material in construction projects. It has many types and wide applications. For artificial sand such as machine-made sand, the preparation process mainly includes crushing, screening, sand washing and other steps. With the development of technology, the sand making process has been continuously optimized. For example, the application of vertical shaft impact crusher and combined sand making process has significantly improved the quality and output of machine-made sand.

[0003] The sand is placed into the feed port and then crushed through the crushing barrel. The crushed sand can be screened through the arc filter below. Those that meet the requirements will be further screened through the conveyor belt, and those that do not meet the requirements will continue to be crushed. The smaller sand screened by the filter element conveyor belt will enter the storage box at the bottom of the filter conveyor belt, and the larger one will pass through the filter screen into the storage box at the top of the conveyor belt.

[0004] The crushing and screening equipment currently used may sometimes block the feed port during the crushing process, resulting in incomplete crushing. In the screening process, the required smaller sand will adhere to the surface of the filter element conveyor belt, causing the filter element conveyor belt to be blocked. In the sand screening process, sometimes a large amount of sand will not fall into the storage box due to the offset of the storage box. In this case, the sand that does not fall into the storage box needs to be manually processed. At the same time, the machine will shake when it is working, causing the storage box to shift. In view of this, we have launched a rotary crushing and separation equipment for the preparation of construction sand. Summary of the invention
