Commonly used crusher jaw crusher, impact crusher, rotary crusher, cone crusher, roller crusher, hammer crusher and vertical shaft impact crusher and so on several.
Is the use of two jaws on the material extrusion and bending effect, crushing or crushing of various hardness of the material crushing machinery.The crushing mechanism by the fixed jaw plate and movable jaw plate composition, when the two jaws close to the material that is Broken, when the two jaws away from the discharge port is less than the bottom of the discharge from the bottom of its broken action is intermittent.This crusher due to simple structure, reliable and can break the hard material and other advantages are widely used In the mineral processing, building materials, silicates and ceramics and other industrial sectors.
Is the use of crushing cone in the shell of the cone in the rotation of the cone, the material produced extrusion, splitting and bending effect, the coarse crushing of various hardness of the ore or rock of large crushing machinery. Equipped with broken cone of the upper end of the spindle support The lower end of the beam is placed in the eccentric hole of the sleeve.
Rotary crusher in two ways to achieve the adjustment of the discharge port and overload insurance: First, the use of mechanical means, the top of the spindle has adjustable nuts, rotating adjustment nut, broken cone can be reduced or rising, so that the discharge port with the change Large or smaller, overload, by cutting off the drive pulley on the insurance pin to achieve insurance; the second is the use of hydraulic hydraulic crusher, the main shaft is located in the cylinder plunger, change the plunger Of the hydraulic oil volume can change the crushing cone up and down position, thus changing the size of the discharge port. Overload, the spindle down the pressure increases, forcing the plunger under the hydraulic oil into the hydraulic drive system accumulator, So that the broken cone will drop to increase the discharge port, with the material into the crushing chamber of non-broken objects (iron, wood, etc.) to achieve insurance.
The working principle is the same as that of the crusher, but only for the crushing machine which is broken or crushed. The uniformity of the particle size of the crushing operation is generally higher than that of the crushing operation. Therefore, in the lower part of the crushing chamber, Set a parallel area, at the same time, it is necessary to speed up the crushing cone rotation speed, so that the material in the parallel area by more than one squeeze.
Cone crusher of the discharge port is smaller, mixed with the material in the non-broken material is more likely to lead to accidents, and because of the fine grinding operations on the string size requirements, must be in the liner wear and tear after the timely adjustment of the discharge port, The insurance and adjustment of the machine is more necessary than the rough operation.
Is the use of the friction of the roller surface of the material into the crushing area, so that it is subject to extrusion or split and broken machinery.When used for coarse or need to increase the crushing ratio, often in the roller surface to make teeth or ditch The roller crusher is usually divided into single roll, double roll and multi-roll crusher for the number of rollers, suitable for coarse, medium or crushed coal, limestone, cement clinker and feldspar Hard in the following material.
Is the use of high-speed impact of the hammer, the material in the broken and crushing operations of the crushing machine hammer articulated in the high-speed rotation of the rotor, the lower part of the body with a grate to control the discharge particle size. Which is crushed by the impact of the hammer of the high-speed movement, and at the same time obtains the kinetic energy, and then crushes into the crushing plate on the inner wall of the shell again. The material which is smaller than the gap of the grate is discharged outside the machine, On the grate again by the impact of the hammer and grinding, until less than the grate after the gap was discharged.
Hammer crusher has the advantages of large crushing ratio, uniform grain size, less pulverized material and low energy consumption, but it is limited by the hammer wear and the application of hard material crushing. In addition, , It is not appropriate to use it to break the humidity and clay containing the material.This crusher is usually used to break limestone, shale, coal, gypsum, chalk and other hard brittle materials.
Is the use of plate hammer high-speed impact and counterattack plate rebound effect, so that the material by repeated impact and broken mechanical plate hammer fixed in the high-speed rotation of the rotor, and along the crushing chamber according to different angles arranged several counterattack plate.
Vertical shaft impact crusher (sand making machine):
This product is suitable for soft or medium hard and very hard materials broken, plastic, widely used in a variety of minerals, cement, refractory materials, aluminum earth clinker, emery, glass raw materials, construction sand, stone and a variety of metallurgical slag , Especially for silicon carbide, emery, sintered bauxite, sand and other high hard, special hard and abrasion resistant materials than other types of crusher production efficiency is higher.
