The discharging size of the impactor breaker can be adjusted according to the production needs. It has flexible application and diversified crushing specification. The crushed materials are cubic shape, no tension and fracture, the grin shape is more perfect. At present, this series of impactor equipment has been widely used in various mineral crushing, high speed railway, highway, energy, cement, chemical, building and other areas, which is the ideal processing equipment for senior highway pavement and hydropower construction.
The Usage and Classification of Impactor Breaker
Impactor breaker is used to crush various materials whose crushing side length is less than 500mm, and comprehensive strength is less than 260Mpa. It has better applicability for granite, limestone and cobble. According to the different rotate modes and crushing materials, this equipment can be divided into three types, namely impact rotary crusher, rock impact crusher and hard rock impact crusher.
Range of Application of Hard Rock Crushing Machine
Due to the simple structure, low electricity consumption, big reduction ratio, even product granularity and other advantages, the hard rock impact crusher is widely used in gravel processing field; it can crush various materials, such as basalt, andesite, cobble, and granite. It is especially suitable to the aggregate production in expressway, railway, nuclear power station, water conservancy project and other special industries.
The Main Factors That Affect the Crushing Fineness of the Impact Coal Mining Equipment
1. The source of the coal. The fineness of the various coal raw materials in coking has direct relationship with the fineness of the discharged mixed coal. The fine raw materials can make the discharged mixed materials finer.
2. The rotor speed. The faster of the rotor speed of the impact coal mining equipment, the finer of the discharged materials. The big crushing rotating speed is 74rpm.
3. The number of the hammerhead. The mare hammerhead, the finer of the discharged fineness. The number of the hammerhead in two crushers has been adjusted for many times, from original 36 to current 22 for 1# crusher, 2#16.
4. The Thickness of the Accumulated Coal in the impact plate of the Crushing Chamber. The thicker the accumulated coal in the crushing chamber of the impact coal mining equipment is, the smaller the coal spacing between the hammerhead and plate is. Therefore, the crushing fineness is finer. But at the same time, the coal accumulated in the impact plate will reduce the rebound kinetic energy of the coal in the impact plate, so, the discharging fineness will decrease relatively.
