It is believed that you, as one in mining machinery industry, are familiar with the impact crusher, which has been put on the market for more than 100 years. During the development process of it, the structure of the impact crusher has been improved constantly. The impact crusher is of simple structure and it is safe and reliable, which can be used in gravel production of different scales.
The PF impact crusher is widely used in sand production line. However, with the constant development of science and technology, there are some new applications of the new-type impact crusher. Recently, the widely used one is the double-rotor impact crusher. Most of the impact crushers used are double-rotor impact crushers.
The double-rotor impact crusher has many advantages, such as simple structure, simple manufacture technique, reliable operation, convenient maintenance, and so on. It is widely used in many industries, such as metallurgy, mining, building material, chemical engineering, coal, etc. Since the 1980s, there has been a great advance of the research and development of the double-rotor impact crusher. On the basis of the features of the foreign products, combining with the actual situation in China, lots of new-type high-efficiency machines have been developed.
As for the double-rotor impact crusher, the levitating height of its movable jaw can be lowered to change the motion track of the movable jaw and the crushing cavity can be decreased and its crushing ratio can be increased. Such an obvious change has increased the productivity and the property of the whole machine to the largest extent, which can finish the production. The double-rotor impact crusher is mainly used to conduct the coarse crushing process in mining, building material, infrastructure construction, and so on. It is applied to crush the soft and hard ore, the crushing strength of which is less than 300MPa.
