Crusher production mechanism of sand fineness modulus can generally reach the number of which manufacturers of grain shape good
The distribution of the three kinds of sand statistics: sieve the bottom of the floor sieve, sieve the remaining stone chips accounted for 20% to 30%, bar mill sand accounted for 20% to 28%, vertical impact crusher (sand making machine ) Accounted for 40% to 45% of sand production Three kinds of sand fineness modulus statistics, the bottom of the sieving stone floor 33-3 for the coarse sand; bar grinding sand machine sand 24 or so for the fine sand, pebble sand making sand 27 ~ 29 for the coarse sand Shanghai Changlei Machinery through the equipment, people, materials, environment, technology and other factors of a comprehensive test analysis to identify key reasons and targeted to take a number of control measures to make artificial sand fineness modulus reached the contract requirements
Production of finished sand by the three parts by a certain proportion of mixed
Fineness modulus is an important measure of the quality of artificial sand, which directly affects the workability, strength, impermeability and economic index of concrete
