Common broken machinery of the top-five, counter-breakers and hammer crusher belong mainly to the impact of brittle materials to broken machines, it is often referred to as the impact crusher. Impact crusher with a compression-based breakers, such as the jaw, Park and roller cone crushers, and other than the following characteristics:
A. Broken ratio. Impact crusher broken more than 50 can be achieved, and jaw, Park and roller cone crusher to more than 20. Therefore, in need of single broken occasions, such as broken rock cement industry, the impact crusher use is widespread.
B. Particle good product. Under the impact, was broken along its materials are often the most vulnerable level fragmentation, this selective broken, the particles form a cube the probability of a higher, the impact crusher machine needle products can be low in percentage Flake 10%, and jaw, Park and roller cone crusher products such as needles Flake percentage content will be higher than 15%. Thus, the need cube particles occasions. For example, the non-slippery highway pavement, usually impact crusher used as a final break equipment, the production of cement aggregate.
These characteristics, the impact crusher in numerous broken machinery occupy important positions.
However, due to the impact crusher principle is broken by the impact of materials, their anti pieces, such as: hammer, hammer plate, plate counterattack, in a very short period of use and wear. Such deficiencies in the long term, the impact crusher limit the scope of application. Hard materials can only be used in the crusher. In the early 1950s, with the application of new wear-resistant materials, Germany KHD company first launched counterattacks hard rock crusher, breaking the limitations of this type, this improved version of the current model is still in production.
China in the late 1950s has come out counter-breakers, in the 1980s, the domestic counter-breakers confined to the processing of ore and rock in such hard materials. Until the late 1980s when the former Shanghai construction machinery manufacturer to introduce counter-KHD-hard rock crushing machine, fill the gaps. But behind abroad more than 20 years.
As the professional manufacturer of complete sets of mining machinery, such as impact breaker,Flotation separator,stone crusher plant,Magnetic drum separator, Henan Hongxing is always doing the best in products and service.
