Different Types Of Impact crusher

Impact crusher can be divided into single rotor and double rotor according to the structural characteristics .

Impact Crusher

 Single Rotor 

The single rotor structure is simple, suitable for medium and small factories. And can be divided into the lower part of casing setting even grate plate and without even grate pull two categories. Lower set even grate plate counterattack crusher. Can control the finished size, reduce the large particles, finished product size is even, this is because the tiny particles through the grate seam after discharge, continue to be large particles remained in grate surface plate hammer blow and grinding, until discharged after crushing. Words of the suspension point of grate plate can move horizontally, to adapt to the working condition of all kinds of broken. Adjust screw laurel grate plate bottom have to adjust the grate plate and rotor Angle between t compensation caused by wear plate hammer and grate plate after clearance.

 Double Rotor 

Double rotor type product rotor type counterattack crusher according to the rotor rotation direction can be divided into three categories:

(1) two rotor rotation direction, the equivalent of two single rotor counterattack crusher series use. Broken than large, finished product granularity and the productivity is high, but the energy consumption is large, can also be crushed, crusher, finely. Simplify the production process. 

(2) the two rotor reverse rotation, equivalent to two single rotor counterattack crusher used in parallel, productivity is high. Can break larger piece of material. Only for crushed and broken in. 

(3) the two rotor is not in the same horizontal plane relative to rotation, can use two rotor relative to throw in material from the phase of the impact and breakage. Broken than large, metal wear less. 

Increase the number of the crushing cavity, can strengthen the selective crushing, broken ratio increases. So, by adding the crushing cavity, can reduce the rotor speed and usually need high speed to reach the effect of broken.

The Impact Crusher Development History

When we trace back to the development history of impact crusher, we found that it first appeared in the 1850s, so it has passed for a long period from the birth of the world's first jaw crusher. With the development of productive forces, old jaw crusher can not fully met the needs of the crushing technology. Thus, the first impact crusher was developed based on the design of the jaw crusher. In 1924, the German first developed two models of impact crushers---single-rotor and double-rotor impact crusher.

Until 1942, the German Andreson summarized the working principle and structure characteristics of the squirrel cage hammer crusher, and based on these, he invented the AP series impact crusher which had the similar structure with the modern impact crusher. It was not until 1950s that China has first real crusher. That is to say, domestic crushing and screening equipmenta are mostly developed in 1950s. In 1980s, our domestic crushers were restricted to process some medium-hard raw materials such as limestone and coal .

Until the end of the 1980s, the introduction of the KHD type hard rock impact crusher filled the gaps. But we have already been left behind for twenty years. At first, the core parts blow bars of the domestic hard rock pf impact crusher mainly depended on imports. And later, the blow bar localization was listed as the ministerial-level scientific research projects in the 8th Five-Year Plan period. Then, after the success of the project, the domestic blow bars not only replace imports, but also a large number of them are exported to Europe, the U.S, Japan and other countries.
