Crusher is the necessary mining machinery equipment in sand production line, both broken line and sand production line, cannot leave the crusher crushing work. Liming heavy industry production of crusher equipment variety, of which the most common and popular in the market are the following four types of crusher equipment: jaw crusher, cone crusher, counterattack crusher, impact crusher. Here, I brought together know more than four kinds of equipment.
1. The jaw crusher
Jaw crusher is the hardness of rock is crushed and broken in work, work way for dynamic JiYaXing. Jaw broken works by motor drive belt and pulley, make through eccentric shaft fixed trajectory of the moving jaw do reciprocating motion, dynamic tooth plate near and far away from the tooth plate, when moving tooth plate near the fixed tooth plate, material is crushed or split, achieve broken; When moving away from fixed gear tooth plate plate, complete broken material from crushing cavity mouth eduction, completed a series of work. With the continuous rotation of the motor, crusher do periodic motion, crushed and broken material, achieve the goal of batch production. Jaw crusher generally used for the early break in the sand and gravel production line, small jaw broken is commonly used in secondary crushing.
2. The cone crusher
Cone crusher is suitable for hard and hard materials in the broken, can be broken and finely worked in finish. The way it works is the motor rotate through the transmission device drives the eccentric shaft sleeve, eccentric shaft sleeve do rotary pendulum movement forced the broken wall, crushing wall near and away from the rolling mortar wall, crushing cavity formation, and the material is broken walls and rolling mortar wall of extrusion and the impact and breakage for many times, when crushing wall left rolling mortar wall, complete broken material under the action of gravity, from the bottom of the cone, to complete the work.
3. The impact crusher
Impact crusher work, under the drive of the motor rotor high-speed rotation. When the material into the work zone plate hammer, and on the rotor plate hammer impact crushing, after again to counter device is broken again, and then rebounded from the back plate to the plate hammer function area broken again. Repeat this process until the material being broken to the required size, is being exhausted from port discharge, broken.
4. Sand making machine
Sand making machine, the way it works is the material from the upper vertical fall into a high-speed rotating impeller, under the action of centrifugal force at high speed, and the other part with umbrella form distribution near the impeller material to produce high speed impact and crushing, the material after the collisions, and between the impeller and casing and other materials to form vortex and crash into each other, the friction and shattered. Until met the requirement of the material granularity, from lower discharge.
