Different Kind of the Rock Crusher

Rock crusher produces gravel and mining ore to be processed and the filling material used for beautify and erosion control, which can be used together with original rock or other materials such as recycled concrete. Rock crusher is either movable or fixed machine though they are usually very heavy.

Rock crusher has different kinds. They are: jaw crusher, impact crusher, capital saving crusher and cone crusher. Jaw crusher squeeze the rocks inside the conical funnel formed between two protuberant surfaces (also called jaw). In most of the design, one jaw of the rock crusher is fixed, but another jaw is swinging at the rate of three times per second. The material enters into the rock crusher from the top. Rocks which are bigger than the bottom opening of the jaw will get stuck in the middle of the two metal plates. However, the swing jaw is striking the fixed jaw and the kinetic energy generated by that will continue to squeeze the jammed rock until they can be squeezed into small pieces which can get through the bottom opening.

As to impact crusher, it is so far the most effective, low consumption rock crusher. Based on those good features, impact crusher plays an irreplaceable role among various kinds of mineral fine broken equipment. Energy saving jaw crusher is the novel generation of the rock crusher, it has bring the advanced technology, optimized the mechanical performance and working principle.

Cone crusher is similar to gyration crusher on the operation; gradient is less in the crushing cavity while the parallel band is more in the crushing zone. Cone crusher uses an axis covered with wear-resisting layer and rotating in abnormal way to smash the rocks and yet the closed concave bucket of the crusher is covered with manganese grooves or bowl lining. When rocks enter into the top of the cone crusher, they will be crushed. Large rocks drop to a lower position to be crushed again. This process continues until the pieces are small enough to pass through the small incision at the bottom of the mill.

Usually, the design of the rock crusher is making slow process. Jaw crusher has been remaining the same in roughly 60 years. More reliability and higher production has been included in the basic design of cone crusher, nevertheless, this design generally remains the same. There is the biggest change in the design is about the rotational speed enhancement. The biggest improvement on stability of cone crusher is the application of hydraulic technology which can protect the rock crusher from the damage caused by not crush objects. For example, steel can cause massive damage in cone crusher and lead cost consumption. The progress of the hydraulic relief system, greatly reduce idle time and improve the lifespan of these machines.

In our country, because of the different kinds of the rock crusher, it is used widely in different lines of work. The rock crushers applied in these two industries each accounted for about 30% of the whole industry. In a word, the rock crusher has good prospects for development.
