The Jaw crusher is use the two jaw board to bend and press the ore,rough or medium crush all kinds of ore with certain hardness.the crushing structure is combined with Fixed jaw board and mobile jaw board,when the two jaw board get close,the ore is crushed,when the two jaw board is separated,the ore which have the samller size than the exit of the crusher,was discharge from the exit.its crushing movement is constantly.this crusher was widely used in mining,quarry,metallurgy,building material,high way railway construction,just because it has simple structure,working reliable,able to crush hard ore.
Cone crusher is suitable to the medium and fine crushing.this kind of crusher have a higher request on the discharge size equality than the rough crushing.therefore,to set up a paralle area under the crushing room,meanwhile ,accelerate the rotate speed of the crushing awl,to make sure the ore will be pressing one time at least.
The Hammer Crusher have a large crushing ratio,the advantage is the finished ore size are equal,less powder,energy saving.the disadvantage is the the easy loss hammer,it has limitation when face the tough material.other side ,because the strip is fraid to block,so it is not suitable for the wet material or caly.this kind of crusher is used to crush the limestone,gypsum,coal,marl,sandstone andshale.
Impact crusher is use the board hammer with high speed rotation and the reflect board reflection ,the ore impact again and again .the hammer is fixed on the high speed rotor,there are several reflect board set along the certain position of the crushing room by certain angle.

the roller crusher is to use the roller surface ‘s friction taking the ore to the crushing area.
When we need to enlarge the crushing ratio or rough crushing,we usually make some teeth or groove gap on the surface of the roller.the roller crusher is named as its quantity of the roller,it is suitable for the rough and medium .fine crushing at the coal ,limestone,cement,long stone etc.
Middle hardness.

The vertical combination crusher applies to construction material,mine,metallurgy,chemical industry.to crush limestone,slag,coal and other ore,which compression resistence is no more than 140Mpa,and humidity no more than 15%
