subject: Artificial Sand Production Line Controls Fineness Modulus [print this page] Artificial sand production line controls fineness modulus
In artificial sand production process, the quality of the finished product of the artificial sand has a direct impact on the quality of concrete, therefore we must be careful in the design of artificial sand production process; according to the loss of many artificial gravel powder dehydration and washing machine was sand, Hongxing machine in sand making process especially uses 5X and VSI series impact crusher (sand making machine) and ancillary equipment (Jaw crusher, Sand washing machine, Vibrating screen, etc.), specializing in the production of artificial sand has merciful finished tablets, adjustable fineness modulus, and low production costs. Hongxing machine under the premise of ensuring the highest production of artificial sand additional research to design a reliable fine sand recovery process, both to reduce the cost of artificial sand production, and increase the amount of artificial sand production and adjust the artificial sand fineness modulus.
Arranged according to Hongxing sand production process, the production of the finished sand is the mixture of three parts by a certain percentage. The allocation of three sand production statistics: the bottom of the sieve floor, the remaining stone chips accounted for 20% to 30%, rod mill production accounted for 20% to 28% sand, vertical impact crusher production accounted for 40% to 45%. The three sand fineness modulus statistics are: the stone chips on the bottom of screening floor is 3.3-3 grit; rod mill type sand making production is 2.4 of fine sand, pebbles sand making production sand 2.7 to 2.9 of coarse sand.
The fineness modulus is an important indicator to measure the quality of artificial sand, directly affect concrete workability, strength, impermeability, and economic indicators. Due to different artificial sand making production ore source around the country, different equipment and processes of production and processing mechanisms sand, there may be a big difference to produce artificial sand and graded. Hongxing machine through the analysis of the full-scale testing of the equipment, people, materials, environment, technology and other factors, identifies key reason and takes a number of control measures to make artificial sand fineness modulus of contract requirements.
