How the impact crusher works

It works crusher hammer crusher and similar, is the use of high-speed rotation of the hammer impact crushing the ore, crushing process but the two are not the same. Figure 1-5-1 shows the working principle of the impact crusher. When the ore enters the crushing chamber, it is subjected to selective crushing by the impact of a high-speed rotating hammer. The ore obtains huge kinetic energy from the impact process and throws it at the high-speed counter-attack plate at high speed. Due to the counterattack effect of the counter-attack plate, the ore is broken again, and the ore that is rebounded by the counter-attack plate is again impacted by the hammerhead and continues to be repeated. The above crushing process. After that, the broken ore is also thrown to the second-stage counterattack plate at a high speed, and further broken. In this way, the ore passes through the continuous impact of the hammer head and the counterattack plate and the collision between the ore, and the crack is generated along the joint surface of the joint, and is broken and broken. When the particle size is smaller than the gap between the hammer head and the counterattack plate, it is discharged from the lower part of the machine into a qualified product.

The basket shaped Johnson screen is a kind of tubal Johnson screen. It is rolled by the wedge-shaped profile wire and the support rod. The shape of slot opening is generally round hole and other holes are square hole, cross hole, bridge hole, arbitrary hole and so on.
