Hammer crusher are: 1, high manganese steel crusher hammer: hardening exponent than other materials 5-7 times higher, you need a strong impact hammer crusher, can only harden rapidly improve the wear resistance, so on stone crusher itself requirement is relatively high. 2, forging hammer crusher: is made of high quality steel train wheels made of hammer crusher classification, the use of metal forging method can be generated in the smelting process cast loose to eliminate defects. 3, carbide hammer: to avoid the cracks, sealing off, chipping off the block and other shortcomings, has high hardness and flexural strength. 4, high network alloy hammer: a very high quality wear-resistant materials hammer crusher models, can be well applied in fine crusher, impact crusher, but due to the high toughness alloys are relatively poor network, If you do not hammer bracing would be prone to breakage. Roll crusher also called on the roll crusher, double roll crusher, roll crusher, is the use of the roller surface friction material will be broken into bite, so bear squeeze or split and broken machinery . Roll crusher usually divided by the number of roller single roll, double roll and multi-roll crusher is mainly used in mining hammer crusher introduction, metallurgy, chemical industry, coal industry coarse brittle bulk materials, intermediate broken, its feed size large, the expected size adjustable, compressive strength of the material ≤160MPa crushing. Especially in the coal industry, the use of the raw coal crusher, long after iron removal, cleaning, no addition to the waste rock, can be directly broken, broken out of the material, uniform size, broken too low, thus simplifying the coal preparation process and reduce investment and production costs.
