Description

TECHNICAL FIELD

[0002] Machine-made sand refers to rock particles obtained by crushing, screening and shaping a series of processes on raw materials such as rocks, pebbles, mine tailings or industrial waste residues, and usually has the characteristics of clear edges and corners, rough surface and controllable particle size. In the production process of machine-made sand (formed by crushing rocks), a large amount of fine particles with a particle size of less than 75 microns will be produced, which are sand powder. Appropriate sand powder can improve the workability of concrete, but excessive sand powder will seriously affect the strength and durability of concrete. Ensuring that the sand powder content of the produced machine-made sand is stable within the standard range can ensure the compliance and stability of the product.

[0003] To ensure the use of machine-made sand, the sand powder in the machine-made sand needs to be separated during production.
