Crushers

crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand or rock dust.

Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated. Crushing is the process of transferring a force amplified by mechanical advantage through a material made of molecules that bond together more strongly, and resist deformation more, than those in the material being crushed do. Crushing devices hold material between two parallel or tangent solid surfaces, and apply sufficient force to bring the surfaces together to generate enough energy within the material being crushed so that its molecules separate from (fracturing), or change alignment in relation to (deformation), each other. The earliest crushers were hand-held stones, where the weight of the stone provided a boost to muscle power, used against a stone anvil. Querns and mortars are types of these crushing devices.

Jaw-impact crushers are used in crusher plant. Primary-secondary-tertiary types

Operating principle

PE jaw crusher uses motor as its power. Through the motor's wheels, the eccentric shaft is driven by the triangle belt and slot wheel to make the movable jaw plate move by a regulated track. Therefore, the materials in the crushing cavity composed of fixed jaw plate, movable jaw plate and side-lee board can be crushed and discharged through the discharging opening
Jaw Crusher Features
1. simple structure, easy maintenance
2. stable performance
3. even final particles and high crushing ratio

Bulk or open-top

Dehong jaw crusher series are based on years experience and technology development. The continuous improvement and refinement has made them the preferred jaw crusher for professionals and our customers.

They can meet most crushing requirements in primary and secondary crushing, and the largest compression resistance of the material is 320mpa. This series are widely used in stone mining, metallurgical, construction, smelting, hydraulic and chemical industries, etc.

The industrial charcoal crusher was named coal crusher machine, coal briquettes grinder, etc. This commercial crusher machine is mainly used for crushing all kinds of charcoal or coal briquettes into small pieces and powder. With high efficiency for grinding charcoal and coal powder, this coal crusher is widely used in charcoal processing plants and various charcoal production lines.

PF Series Impact Crusher is one kind of equipment to crushing the brittle material which compression strength no more than 350 Map, the advantage including high crushing ratio, uniform product grain and low over crushing, low energy consumption, high adjustment range of product grain size and optional crushing etc, which is mainly used in mine, metallurgy, cement, construction material, coal etc for secondary crushing and fine crushing the medium hardness material.

Application:
Metallurgy, construction material, mine, beneficiation and large block material crushing.

Our advantages:
1. Large feeding port and high crushing cavity, suitable to crushing the material with high hardness and big grain size, and less powder.
2. The gap between impact plate and hammer plate is adjustable, so the discharging grain size can be effective control and the grain shape is well.
3. The hammer, impact plate and lining plate are made of new type abrasion-proof material with long working life and impact protection, wear protection.
4. Because of the function of three-stage crushing and plastic, so the crushing ratio is high, and the product shape is cube and can optional crushing.
5. The multi-function hydraulic station has many function of hydraulic discharge gap with high speed, impact plate stable vibration and the body open automatically.

The PF series impact crusher is mainly compose of the rack, driving system, rotor, hammer and impact plate etc. The main feature including:
1.Rack: It composed by two parts of upper and lower with connection by bolt. All the parts contact the crushed material in the rack have set replaceable lining plate.

2. Driving System: The main shaft and rotor are driving by motor through belt then doing the high speed rotary motion.

3. Rotor: It adopts entire cast steel structure with high mass force, solid and durable, convenient to install the hammer.

4. Impact Plate: It is made from new type abrasion material and hanging freely inside the equipment. One end connect with the two sides of the rack through hanging shaft hinge, another end is bearing in the upper rack cone gasket through stay bolt which is adopt a sphere gasket, it can prevent the equipment damage by non-crushing material when crushing material.
5. Hammer: It is made from new type abrasion material and fixed on the rotor through wedge block

Low Consumption Mining Crusher Machine , Rock Jaw Crusher is crushing equipment which mainly be applied in metallurgy, mine, chemical industrial, cement, building, fireproofing materials and ceramics and other industries to process middle hardness mineral. It is mainly used in various soft and hard mineral whose compression strength is no more than 300MPa, and the size of the biggest lumpiness should not be bigger than that of technical specifications.
