"The counter-impact crusher is a new type of crushing equipment, which mainly relies on impact to crush materials. The crushing process is roughly like this: after falling materials enter the entrance of the crusher, they are hit by the impact of a high-speed rotating hammer. Go to the adjustable wear-resistant tooth plate at the entrance of the crusher for secondary crushing; the crushed material enters the main crushing chamber and is crushed three times; in the main crushing chamber, the kinetic energy is obtained again in the impact of the hammer, and the high-speed impact It is broken towards the serrated liner inside the counter-attack cavity, and the broken material rebounds downward again, and is broken again by the hour...Due to the action of gravity, the material continues to move towards the lower outlet. In this way, the anti-capsule circulates in the anti-cavity After many times of crushing, the crushed material is discharged from the discharge port, and the finely crushed material is the product.
The machine is mainly composed of the main body of the crusher, electric motor, hydraulic coupling, hydraulic station, shock absorber and so on. The structure adopts a large rotor, a short pin shaft, a combined hammer head, an upper and lower synchronization adjustment device, and a wear-resistant tooth plate is added at the entrance of the machine body, which increases the crushing zone and improves the crushing rate. It has the advantages of large blow 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 for decades. The hammer head is combined, which saves a lot of wear-resistant alloy materials and reduces production costs. The hammer head connection is equipped with reinforcing ribs, and the width of the striking end is widened, which improves the strength of the hammer head, changes the shortcomings of the original model, and greatly improves the safety.
And hammer life. At the same time, the hammer heads are arranged in a spiral line, which is very beneficial to the impact force of the rotor, reducing the air volume and preventing blockage. The main engine and the motor are connected through a fluid coupling, which effectively reduces the damage of the motor during starting and running. The lubrication at the bearing is directly supplied by the hydraulic station, without manual supply, which reduces the labor intensity of the workers." |
