1, Impact Crusher can effectively handle the large amount of moisture content of materials, to prevent the blockage of the phenomenon of Crusher
In dealing with excessive moisture content of materials, the counter-attack crusher feed chute and the back plate can be equipped with heating devices to prevent the bonding material. Impact Crusher is equipped with the bottom of the sieve plate do not need to be effective in preventing clogging phenomenon. The hammer crusher can not be used to prevent heating of the bonding material, and shall be equipped with the bottom of the sieve plate, increasing the possibility of clogging.
2, back-breaking not only for soft materials also applies to very large hardness of materials
Hammer Crusher board mechanical clamping structure firmly set at the rotor, when the rotor rotates, with the great moment of inertia. Relative to the hammer crusher (hammer was hanging state), back-breaking of the rotor has a greater momentum, crushing harder to adapt to the material, were also lower power consumption.
3, Impact Crusher can be easily adjustable and flexible discharge particle size, a wide range of adjustment
Impact Crusher can be adjusted through a variety of ways out of material particle size, such as the regulation of rotor speed, adjustable back plate and grinding chamber gap and so on. Gap adjustment can be mechanical or hydraulic adjustable, hydraulic-conditioning systems can be easily adopted by local operating buttons or remote controls system to complete the space adjustments. The hammer crusher discharge size adjustment can only be achieved by replacing the bottom of the sieve plate.
4, Impact Crusher wear wearing parts than the hammer crusher is small, high utilization rate of metal
Hammer Crusher wear plate only appears in the Looking material side. When the rotor speed is normal, the feed will drop to the board hammer surface (of attack), hammer on the back and side panels are not being worn. Even Looking material this side of the wear and tear would be minimal. And the bottom of the grinding rod is also very easy to replace. Back-breaking hammer the metal plate up to 45% utilization rate of -48%. The hammer crusher hammer was hanging condition, wear and tear occurred, the front and rear and side, relative to the plate hammer, hammer wear and tear is more serious, hammer metal utilization ratio is only about 25%. And the rotor body itself may be subject to wear and tear. Hammer crusher wear seriously affected by the bottom of the sieve-plate, grille should all replace, and replace the sieve of the work more complicated.
5, Impact Crusher spare parts replacement is simple, a corresponding reduction in maintenance costs
Broken rotor only counter to install six panel hammer, special tools can be easily board hammer replacement, the replacement of a board of only one frequency hammer time. The bottom of the grinding chamber grinding rod replacement also requires only several minutes, greatly reducing the repair and maintenance time and costs. The hammer crusher hammer up to more than 100, with the replacement of a hammer to spend a lot of time and manpower, repair and maintenance costs higher. The bottom of the screen plate and its replacement is also troublesome.

A Jaw Crusher is one of the main types of primary crushers in a mine or ore processing plant. The size of a jaw crusher is designated by the rectangular or square opening at the top of the jaws.Jaw Crushers are ideally suitable for primary and secondary crushing, with low power consumption and easy maintenance. Every feature of these machines has been carefully designed to provide superior quality and performance.

A jaw crusher reduces large size rocks or ore by placing the rock into compression, a fixed jaw, mounted in a “V” alignment is the stationary breaking surface, while the moveable jaw plate exerts force on the rock by forcing it against the fixed jaw plate. The space at bottom of the “V”, aligned jaw plate， is the crusher product size gap, or the size of the crushed product from the jaw crusher.

The motor drives the mobile jaw up and down through eccentric shaft. The angle between toggle plate and mobile jaw increases when mobile jaw plate moves up. So the mobile jaw plate closes up the fixed jaw plate. The stuff will be crushed in this process. The angle between toggle plate and moving jaw decreases when mobile jaw moves down. The mobile jaw plate move away from the stationary jaw plate with the pull of draw rod and spring, so the crushed stone will be discharged from the outlet. This process will repeat. The moving jaw will crush and discharge the stuff circularly.

Due to the advantage of simple structure, reliable performance, convenient maintenance and safe use, our jaw crushers of various sizes are widely used in the crushing operation in metallurgy, mining, building materials, chemical industries and cement enterprises.

Cone crushers reduce large rocks into smaller sizes for further use in construction. Several types of crushers are used for this purpose, and the cone crusher is an important type that is efficient, stable, and safe.

Purpose Of A Crusher

A crusher is a mechanism that is intended to cut big rocks into small sizes, or rock powder. Crushers are also used to decrease the size and change the shape of waste substances for easy disposal or recycling. Size may also be reduced for easy identification and differentiating for further application. Crushing involves transfer of a force that is amplified considerably by the mechanical advantage obtained through materials whose molecules are bonded strongly. These molecules offer greater resistance to deformation, compared to the materials that are being crushed. Crushing tools hold the material to be crushed between two solid surfaces that are parallel. Force is applied to bring these surfaces close to each other. Sufficient energy is generated inside the material that is being crushed, and consequently the molecules are separated. The initial crushers were stones held by hands, and the stone weight amplified the human power.

Cone Crusher Functioning

The cone crusher is a machine used in the construction industry for crushing different varieties of rocks and ores of varying hardness. Cone crushers have a stable structure, an efficient and simple adjustment, and are used extensively. The crusher functions by pushing on substances held between the fixed cone and the movable cone. The cone crusher splits the rocks by clutching them between an eccentric rotating spindle that is enclosed by a tough layer, and a concave hopper. As the rocks enter the crusher, they are wedged between the layer and the concave hopper. Big pieces are broken, and then these are dropped to another position, where the breaking process is repeated. This procedure is continued until the rocks are small enough in size to descend through the restricted opening at the crusher bottom.

Cone Crusher Safety Mechanism

The cone crusher is fitted with a spring release safety system that performs as an overload safety device. It permits extremely hard materials to move through the chamber without damaging the crusher. The safety arrangement utilizes water and dry oil to produce plaster powder for preventing the movement of hard objects. Furthermore, to ensure reduction of the stresses on crusher parts, the loads are distributed equally over a big enduring area. Springs are incorporated as safety features to avoid damage during the cone crusher operation. These springs exert pressure on the top frame. If some pieces that cannot be crushed enter the system, the springs activate the liner to rise and prevent damage.
