subject: The History And Introduction Of Impact Crusher In The World [print this page] The history of the impact crusher dates back to the 1850s. The Worlds first impact crusher was born in America. Before long, because of the development of the productive forces, jaw crusher cannot meet the need of crushing technology; therefore, people designed counterattack crusher on the basis of jaw crusher. In 1924, the German first developed the single and double rotor two types of impact crusher. At that time the crusher of structure is similar to the modern squirrel-cage crusher. Because no matter from the structure or the work principle analysis, it has the characteristics of the impact crusher. Because the material needs repeat impact, the broken can be free or shine in the process of discharging. But due to the limit of the feeding strength and impact breaker ability, the model gradually transferred into the squirrel-cage crusher, used in the fining of medium hard. In 1942, the German Anderson in summarized the squirrel-cage crushers hammer crusher of the characteristics and working principle foundation and invented the AP series impact crusher, whose structure is similar to the modern impact crusher. Benefit from the higher production efficiency of this impact crusher and its simple in form structure, convenient to move, so, this impact crusher has developed rapidly.
Impact crusher can adjust the granularity of the materials by a variety of ways, such as regulates the rotor speed, adjust the clearance between impact plate and the grinding chamber, etc.Impact crusher and other mining equipment produced by Hongxing machinery are essential in mineral processing, metallurgy, construction of high-speed rail and other projects; we have been committed to research about crusher equipment, optimize internally structural, improve product efficiency according to market demand and thus standing out in many crusher manufacturers; our products win highly praise of customers by its high efficiency, large output and flexible adjustment.
The new equipment uses the many kinds of advanced equipment, for example, using a variety of charging device makes charging continuous stability, charging process wont produce the bridge phenomenon. The bottom of the impact crusher adopts the special cooling device, avoiding the sticking and metamorphic phenomenon. The use of special pressure sealing device and bearing cooling equipment can prolong the service life of the transmission. The special air distribution device can reduce the equipment resistance, and can provide the blowing rate of impact crusher. The agitating device can engender strong shear, blowing, rotating effect. The air filter, the cyclone separator, and bag dust extractions can effectively remove dust to avoid environment and material pollution, etc. The equipment is widely used in soybean protein, gelling starch, wheat starch, etc food materials.
The impact crushes materials with impact force. When the materials enter the blow bar area, they are crushed due to the high-speed impact of the blow bar and are thrown to the impact plates on the rotor for secondary crush. Then the materials will be shot back to the blow bar again for the third crush. This process repeats until the materials are crushed to the required size and discharged from the lower part of the machine. The size and shape of the finished powder can be changed by adjusting the gap between the impact rack and rotor support. The machine employs self-weigh security device in its back frame. When other objects enter the impact cavity, they will be forced out of the machine by the impact rack in the front and back of the machine.As the professional manufacturer of complete sets of mining machinery, such as mobile crushing station.
Mobile stone crusher machine is a kind of stone crusher series and also the most common crusher in the stone crusher series . Mobile Crusher is adaptable to all mobile crushing needs, Mobile Crusher set up a new range of business opportunities for contractors, quarry operators, recycling and mining applications. The mobile crusher plant for stone crushing features low transportation cost, flexible configuration, easy maintenance and etc. The mobile crusher plant can not only work independently, but also be combined with other machines in a production line. There are mainly several kinds of mobile crusher plant, that is jaw mobile crusher plant, cone mobile crusher plant and impact mobile crusher plant.
The Mobile Crusher (mobile crushing and screening plants) is composed of primary crushing and screening station and secondary one, belt conveyor, etc. Every crushing station is an independent working unit, they can respectively assume their different responsibility, and the belt conveyer is responsible for material transmitting and piling up between each crushing station.
