Product Description

The counterattack fine crusher produced by our company introduces good technology, combines the working principle of various types of sand making machines, and adopts the energy-saving sand making equipment designed based on their common points according to the information feedback of users' specific use conditions. The impact crusher has the technical advantages of strong production capacity, convenient operation and environmental protection. It is mainly suitable for fine crushing of medium hard materials such as granite, basalt, limestone, river pebble, cement clinker, quartz, iron ore and bauxite and manual sand production.

Product Advantage

Impact crusher is used for fine crushing of various medium hardness solid materials. It is widely used in industrial departments such as building materials, chemical fertilizer, mining and refractory materials. It has the characteristics of small discharge particle size, uniform particle shape, large production capacity, long service life of hammer head, small supporting power, simplified process (changing three-stage crushing into two-stage crushing), simple structure, convenient maintenance and stable operation. High efficiency, energy saving, wear resistance and compression resistance. The crushing ratio is large, the crushing efficiency is high, the rotor has large moment of inertia and low energy consumption; High chromium plate hammer is used to resist impact and wear, effectively prolonging the service life of vulnerable parts. Simple structure, convenient maintenance, simple machine structure, mainly composed of casing, rotor and impact plate. Through the jacking device, the rack can be quickly opened to replace and repair the machine parts; The expansion sleeve keyless connection is adopted between the rotor and the main shaft, which is convenient, economical and reliable. The discharge particle size is adjustable. The top of the granular machine is equipped with a discharge port adjustment device, which can simply and quickly adjust the gap between the counterattack plate and the plate hammer to control the discharge size; The finished product is cubic in shape, without tension cracks and small in particle shape, which meets the grade standards of various sand and gravel aggregates.

Working Principle

When the material enters the plate hammer action area, it is crushed by the high-speed impact of the plate hammer, thrown to the impact device installed above the rotor for crushing again, and then bounced back from the impact lining plate to the plate hammer action area for crushing again. This process is repeated until the material is crushed to the required particle size and discharged from the lower part of the machine. Adjusting the gap between the counterattack frame and the rotor frame can change the particle size and shape of materials. The machine adopts spring safety device behind the impact plate. When the non broken objects enter the crushing chamber, the front and rear impact frames retreat, and the non broken objects are discharged from the machine.
