Due to the various types of the current crushing and powder grinding equipment such as rotary kiln and vibrating screen, the selection and use of them for the customers has very big room to choose from. Since the roller crusher has small crushing granularity, it has become the first choice for many production companies. Here Hongxing Machinery will introduce some structural designing features of this machine. In recent years, with the development of national economy, construction of infrastructure projects are also increasing, especially in the highway, high-speed railway, urban subway, second - and third-tier cities for the construction of the airport is in full swing. With the improving of the social science and technology level, the requirement of infrastructure projects for stone becomes more and more high, at present, most commonly used stone crushing machine is the jaw crusher and Cone Crusher, the crushing of stone flake material proportion is very big, the influence of aggregate gradation is large, resulting in concrete quality is not stable, the road is difficult to guarantee quality.
Henan Henan Hongxing heavy machinery co., LTD. The product Vertical Shaft Impact Crusher, based on the advantage of development of PF series impact crusher, is a kind of new, highly effective, finely crushing equipment, its structure is simple, easy maintenance, less work wear consumption, operation cost is low. Such breakage function produces nearly cube stone, it is crucial to the production high quality concrete. Henan Hongxing heavy industry research and development manufacturing PF impact crusher is based on the impact crushing mechanism.
Original stone are accelerated to very high circumferential velocity inside the rotor, in under the action of centrifugal force by the rotor side outlet at a speed of 50 ~ 85 m/s to the outside, and from the mouth of falling stone particles of completely elastic collisions occur, are breaking stone particles: from collisions with other particles in the crushing cavity repeatedly, grinding, turbulent flow in cavity, and the closer the crushing cavity wall, the smaller stone particles, the lower the speed, soon lose energy stone particles falling into a finished product bin. During crushing cavity wall has a layer of low speed near the small particles of stone, stone and this layer provides a layer of stone lining for crushing cavity.
