Description

Technical Field

[0001] The present invention relates to the technical field of sand making, and in particular to artificial sand making equipment and a preparation process thereof. Background Art

[0002] Artificial sand making refers to the process of turning stones into sand by mechanical equipment in a sand making machine. The surface of artificial sand particles is rough and angular, the aggregate is well bonded with cement and aggregate, and the mechanical bite force is high, so the concrete made with artificial sand is stronger than that made with natural sand. After the sand making machine completes the sand making, the sand is screened through a metal mesh screen. The metal mesh screen divides the sand into sand products of different diameters according to the different sizes of the mesh. The sand that meets the requirements of artificial sand is mixed and stored in the sand field, and the sand that is too large is put into the sand making machine again for sand making.

[0003] However, in the process of stone processing, due to fierce collision and the fact that the stone itself has a certain amount of soil, the artificial sand will contain a certain amount of mud powder. The presence of mud powder will seriously affect the gradation of sand, and the existing technology uses water washing to remove soil, which wastes a lot of water resources, and requires mixing sand and gravel, which requires additional machinery for mixing.
