reversible impact crusher is a new type of crushing equipment mainly for impact crushing materials. After the falling material enters the entrance of the crusher, it is impacted by the high-speed rotating hammer head and hits the adjustable wear-resistant tooth plate at the entrance of the crusher for secondary crushing; after crushing, the material enters the main crushing chamber, and then is crushed three times; in the main crushing chamber Under the impact of the hammer head, kinetic energy is obtained again, and the jagged liner rushing into the reaction chamber at high speed is crushed. The crushed material rebounds downward again, and then is crushed by the hammer head... Under the action of gravity, the material continues to move upward. Moving in the direction of the low outlet, such repeated cycles, multiple crushing in the anti-cavity, and finally the crushed material is discharged from the discharge port, and the crushed material is the product. The machine is mainly composed of crusher body, motor, hydraulic coupling, hydraulic station, shock absorber and so on. The structure adopts airfoil rotor, short-pin shaft combined hammer head, up and down synchronous adjustment device, and wear-resistant tooth plate is added at the entrance of the machine body, which increases the crushing bell and improves the crushing rate. It has the advantages of large impact force, uniform discharge fineness, convenient operation and maintenance, and long service life of wearing parts. The main shaft of the crusher is made of high-quality alloy forged steel. This material and its heat treatment technology have been very mature in the application of large-section shaft parts. The combination of hammers saves a lot of wear. Use high-quality alloy materials to reduce production costs. The hammer head joint is equipped with reinforcing ribs, which widens the width of the striking end of the hammer head, improves the strength of the hammer head, changes the shortcomings of the original model, and greatly improves the safety and service life of the hammer head. Simultaneously. The hammer heads are arranged in a spiral, which is beneficial to improve the impact force of the rotor. The main engine and the electric motor are connected through a hydraulic coupling, which can effectively reduce the damage of the electric motor during starting and running. The lubrication of the bearing is directly supplied by the hydraulic station, without manual oil supply, which reduces the labor intensity of the workers.
Advantages and features reversible impact crusher
It has the following characteristics such as lower energy-consumption, high efficiency, high reduction ration;
It has reasonable structure, equipped with the buffering and damping device. The machine body shocks small with lower noises and high strengthen. Crushing force of impacting material is effected on the impact part to overcome the defect of machine body deformation caused by material impact;
Monitoring door are set reasonably. Hinges for upper and bottom machine body, open the upper cover by hydraulic controlling, convenience to maintain and inspect;
It is designed with regulating part to adjust the pre-tightening force of spring easily to control the discharging size effectively and satisfy the crushing ratio;
Its hammer adopts the newest high hardness and wear-resistant material to improve product performance greatly and prolong product service life;
The impact part adopts the newest hardness, impact-resistant material with the design of tooth; regulating part adopts the newest hardness and wear-resistance material.
A reversible hammer crusher is a new type of crushing equipment, general configuration by crusher main engine, motor, torque limiting hydraulic coupling, and liquid opening device. The spindle and hammer handle is forged with 42CrMo alloy steel. The hammer head and village plate are cast with high wear-resisting alloy. Because it is different from the design concept of an ordinary crusher, the structure of the large rotor, short pin shaft, and reversible rotary combination hammer, has the advantages of large impact, easy operation, and maintenance, and low operation cost. PCK series reversible hammer crusher, used for crushing brittle materials with a medium hardness of ore compressive strength not more than 150Mpa (1500 kg/square cm), such as coal, limestone, gypsum, soft refractory materials, etc.
The crushing process is generally like this: after the falling material enters the crusher, it encounters a high-speed rotating hammerhead; after being hit, it is hit on the adjustable wear-resistant tooth plate at the crusher entrance, and is crushed for the first time, after crushing, the materials with basically the same particles enter into the main crushing chamber evenly, and the second main crushing is carried out. The homogenized materials in the main crushing chamber obtain kinetic energy again from the hammer. After the upward rebound of the sawtooth-shaped lining plate, the material is broken again by the Hammerhead, and at the same time, the material is also broken by the impact of each other, and so on. In the counter-attack cavity broken many times, the final broken material from the discharge port discharge, fine broken material is the product.
