2. Machine-made sand production equipment and process. Process flow of machine-made sand production: The basic production process can generally be divided into the following stages: ore lumps → coarse crushing → medium crushing (partially set screening) → fine crushing → screening → dust removal → machine-made sand.
State-of-the-art compacting technology for sand molds can make a significant contribution to casting efficiency provided that the molding sand consistently meets stringent quality criteria. The essential quality criteria for molding sand are: Exact compliance with compactability specifications Excellent flowability Uniform strength
It should be noticed that the tensile strength of MSRAC is lower than current specification, and tends to reduce with the increase of water to cement ratio. ... Experimental study was carried out on the concrete mixed with machine-made sand and recycled coarse aggregate (MSRAC), three strength grades of concrete were designed by changing the ...
