Stone production line is equivalent to the combination of sand production line and sand production line, in road construction, building materials such as production line often need to stone production line, is a production of construction sand and stone dedicated production lines, in the stone production line break is the most in the unit, according to the different requirements with different crushers.

Crushing the basic form of this stage consists of a single stage  quarry crusher , with pre screening and crushing stage, with control screening crushing stage, with pre screening and inspection check breaking phase of the difference between them is that the former is pre screening and checking screening is no longer with a sieve of, which is on the same screen, so is by difference, more than two pieces of broken process is different crushing stage forms of combination, so there are many possible scheme, but reasonable crushing process can be to be determined according to the need the broken segment number and the application of pre screening and inspection check screening of necessity.

The maximum size of ore mining method and ore given conditions, ore size, have a relationship, the transportation, the final product size is broken broken purpose, reasonable crushing product size mainly depends on the comparison between the process requirements and technical and economic results, the maximum particle size required depends on the number of broken ore, the final crushing product size and each crushing stage can reach the ratio that depends on the total requirements of each and crushing crushing ratio, on the other hand, determine the final crushing product size must be considered when the actual size selection of crusher, crushing product can achieve, not exceeding the allowable discharge adjustment range in order to get smaller, the crushed product size in equipment under license.
