What kind of crusher is used for the second crushing?
There are counterattack crusher, hammer crusher, impact crusher, most will choose to use counterattack crusher. But it also depends on the actual crushing material. Suggest that you listen to the opinions of experts according to your actual working conditions.
And the best break with the counterattack, because the country has already stipulated, a variety of told Highway Stone, railway stone, and must be broken, counterattack. With other broken out, do not meet national standards, generally no one dares to use your stone
1, stone production line, second crushing, counterattack crusher2, sand production line second crushing with counterattack efficient sand making machine1 、 main equipment of stone production line:Stone production line, crushing material hardness is less than 320Mpa, such as granite, basalt, is suitable for two stage crushing process, the main equipment are: vibrating feeder, jaw crusher (a broken stone crusher (two) - can be broken, crusher, hammer crusher, impact crusher, vibrating screen) - finished stone, in the middle of the belt conveyor transmission material.Stone production line flow:First of all, the stone from the feeder evenly sent an initial coarse crusher crushing, and then produced into the coarse material by belt conveyor to the two stage crusher (crusher, hammer breaking) for further crushing, fine crushing stone into the shaker distinguish different specifications of stones, to meet the requirements of the stones size by finished belt conveyor to finished material pile; gravel does not meet the size requirements by belt conveyor feed back to the crusher are broken again, forming a closed loop several times. The particle size of the finished product can be assembled and graded according to the user's requirements. It can be equipped with auxiliary dust removal equipment to protect the environment.2 、 main equipment of sand and gravel production line:Sand production line of general material for quartz stone, limestone, sand production line production process is basically the same, the main equipment: vibrating feeder, jaw crusher (usually two, PE and PEX thick broken jaw crusher, jaw crusher thin broken stone hardness is low, you can omit the thick broken) - sand (general machine for shock type, can also be used instead of roller crusher) - shaker - sand washing machine, sand product, in the middle of the belt conveyor transmission material.
