How much can the fineness modulus of the sand machine produce in the mechanism of the crusher production? Which manufacturer has a good grain shape?
Fineness modulus in 3.7-3.1 is coarse sand, in 3.0-2.3 is medium sand, in 2.2-1.6 isFine sand. The fineness modulus range of ordinary concrete sand is 3.7-1.6, and medium sand is appropriate.
Building sand has always depended on natural sand, and the endless exploitation of natural sand has led to less and less resources. Now, people have come to realize that it is necessary to produce machine-made sand to meet the increasing demand for sand.Artificial sand processing equipment: crusher, counterattack crusher crusher, cone crusher, impact crusher, etc. various types, according to the different needs of users, the appropriate allocation mechanism of sand production equipment.
Rod mill type sand making machine, about 2.4 of the sand is fine sand, and the sand making machine for pebbles is 2.7 to 2.9 of medium sand.
The finished product sand is made up of three parts according to a certain proportion. Three kinds of sand production distribution statistics are: screening floor sieve bottom, the sieve remaining stone chip accounted for 20% ~30%, rod mill sand accounted for 20%~28%, vertical impact crusher (sand making machine) sand production accounted for 40%, ~45%. The fineness modulus statistics of the three kinds of sand are: the bottom of the sieving building is 3.3-3, and the coarse sand is coarse sand;
Fineness modulus is an important index to evaluate the quality of artificial sand, which directly affects the workability, strength, impermeability and economic index of concrete.
