Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of machine-made sand production, in particular to a vibrating screener for machine-made sand production. Background Art
[0002] Artificial sand refers to sand processed by sand making machines and other ancillary equipment. It can also be called artificial sand. It is made of raw materials such as rocks, mine tailings or industrial waste slag, and is made through processes such as soil removal, mechanical crushing, and screening. The rock particles with a particle size of less than 4.75 mm, but excluding soft and weathered particles, are more regular. They can be processed into sand of different rules and sizes according to different process requirements, and can better meet daily needs. Compared with natural sand, artificial sand has the advantages of uniform particles and stable quality, and its price is relatively low. However, at this stage, before the sand making machine performs sand making operations on the raw materials, the raw materials will contain sand and gravel that can be directly used as finished sand. If they are not screened and directly put into the sand making machine for sand making operations, these finished sands will be subjected to secondary sand making, making the stone powder content in the artificial sand higher. Too high a stone powder content in the artificial sand will reduce the dynamic elastic modulus of the concrete, and will also be detrimental to the concrete's resistance to chloride ion permeability and sulfate erosion.
