With the improvement of the coal situation and the good operation of the market in recent years, the coal machine manufacturing industry closely related to it has made remarkable achievements, and the crusher, which is one of the modern high-yield and high-efficiency shovel comprehensive mining equipment, plays in it. Important role. The design and manufacturing level of the crusher has also been rapidly developed. The crusher used in coal mines can be divided into hammer crusher and jaw crusher, and hammer crusher is widely used.
The use process of the hammer crusher in the underground coal mine: the coal produced by the mining face is transported by the scraper conveyor to the unloading section of the transfer conveyor installed in the chute, and the crusher is installed in the middle of the unloading section and the climbing section. It can be regarded as a part of the loader, and the bulk material transported by the transfer machine is broken. It must be used with the transfer machine, and it does not have the function of conveying materials. Its structure is mainly composed of bottom trough, crushing frame body, breaker shaft, transmission device and adjusting device, lubrication system, etc. The crushing bottom trough is connected with the coupling groove of the transfer machine, and the scraper chain passing through it will be broken. The material is continuously fed into the crusher, the crushing frame body is installed in the upper part of the bottom tank, and the crushing hammer shaft is installed in the middle of the frame body, which is one of the very important components in the hammer crusher. The working principle of the crusher is to drive the broken hammer shaft through the transmission device. During the rotation, the coal conveyed by the transfer machine is broken and crushed by the hammer, and the incoming coal is broken and broken.
