AC Motor PFQ1110 High Efficiency And Energy-Saving Model Impact Crusher Machine For Stone Yard And Mixing Station

1. Description

PFQ crushing impact crusher is a series of products designed and developed by our company with the introduction of new French technology, which is mainly used for primary crushing operations. When processing materials with compressive strength less than 150MPA, the maximum feed rate is 1400MM, which can replace the jaw crusher, gyro crusher and other coarse crushing equipment as the primary crushing equipment. This machine is suitable for processing artificial sand and gravel in hydropower, highway, urban construction and other industries.

2. Features

• Especially designed three crushing chambers, which improves the production capacity of impact crusher, make the feed size bigger and the product shape better.
• The optimally designed rotor provides powerful rotational inertia and strong impact force of hammerhead, which improves the productivity and increases the crushing ratio.
• Especially designed anti-wear alloy C shape hammer keeps the shape of impact face in the product life cycle. It ensures that the product shape and particle size distribution is very stable.
• Standard modular designed liner and tooth impact plate of impact crusher have common-ability and interchangeability, which improve the utilization ratio and prolong the service life of impact crusher.
• The standard hydraulic lifting device will be provided with the machine. It is optional to supply special lifting tools for replacing hammers, which is flexible and can be easily maintained.

3. Advantages

• The new rotor body can provide extremely high moment of inertia and hammer impact crushing force, and improve the rate of finished products in one-time crushing of materials.
• The unique "S" hammer head design keeps the contour shape of the crushing surface unchanged during the entire life cycle, ensuring stable product gradation.
• The novel hammer head is fixed without bolts, which makes it more convenient, quick and efficient to replace the hammer head.
• The counterattack frame is suspended by its own weight, and the discharge gap is adjusted by a ratchet device, which replaces the spring adjustment device with more failures.
• There are few types of wearing parts and high pass rate, which reduces the cost of spare parts for users.
• The stop lock structure of the rotor makes the replacement of wearing parts safer and faster.

4. Working Principle

The impact crusher is a machine equipment that uses impact energy to crush materials. As far as the form of using mechanical energy is concerned, the crusher using the "free" crushing principle of impact force is superior to the crusher using the static pressure crushing principle.

The impact crusher uses the impact force "free" crushing principle to crush materials. When the material enters the crusher, it is impacted by the high-speed rotating beating plate, and the material is selectively crushed along the bedding surface and the cleavage surface. After being impacted, the material gains huge kinetic energy and is thrown at a very high speed along the tangential direction of the strike plate to the first stage counterattack board. After the impact of the counterattack board, the material is crushed again, and then from the first stage The material returned by the counter-attack plate was hit again by the strike plate and continued to be crushed. The crushed materials are also thrown to the second-stage impact board at a very high speed, and are crushed again, resulting in an "interlocking" type of crushing effect in the impact crusher. When the material goes back and forth between the strike plate and the counterattack plate, in addition to the impact effect of the strike plate and counterattack plate. There is also the interaction between the materials.
