With the development of science and technology of the society, there will be more and more new equipment in front of us, impack crusher is a new type of high efficiency crushing equipment, especially the broken hard ore and abrasion is more serious, often need to change. At present due to the emergence of some wear-resisting material, has been applied in some metal concentrator.
Thanks to this counterattack crusher production efficiency is higher, can handle larger materials, as well as it in the form of the structure is simple, convenient maintenance, so the counterattack crusher has been developing rapidly. With more perfect of crushing screening crushing theory and technology further development, all sorts of high-performance counterattack crusher also emerge in endlessly, at the same time, in order to enhance the crusher mobility has also developed wheeled and tracked mobile crushing station, including wheel type crusher is more popular, more popular crawler. Counterattack crusher’s development in China are late, the 50 s of the last century, our country really have crusher, and so, crushing screening equipment in our country are mostly appeared in the 50 s. In the 80 s, before the impact breaker made in our domestic limited to deal with hard materials such as coal and limestone. A use of impact energy to break the material of broken machinery. Machine work, under the drive of the motor, the rotor high-speed rotation, the material into the plate hammer function area, and the rotor plate hammer impact broken, and then again to counter device is broken, and then back to the board from the back plate hammer function area is broken again, this process is repeated, material from big to small back into one, two, three cavity repeated broken, until the material being broken to the required size, is being exhausted from port discharge. Forming closed-circuit circulation many times, controlled by the screening equipment to achieve the required size. Counterattack crusher suitable for hard materials in the broken, the typical granite discharging granularity 25 mm or less accounted for 85%. Such as cement limestone crushing. Has great capacity of production, the advantages of small discharge granularity.
So counterattack crusher is a kind of new equipment, there are so many way to let us choose a applicable, is also a concern to help to our work.
