Crushing chute is the carrier of friction for the scraper chain to transport coal and gangue, and it is also the impact force of coal and gangue in the crushing process. In the working process of the crusher, the crushing bottom groove plays a key role, which is not only the running track of coal and gangue, but also bears the impact force of the hammer on the coal and gangue, and transmits these forces to the corresponding parts of the crushing bottom groove.

1. The crusher box is usually made of high quality alloy steel plate welded together. This choice of material ensures the strength and durability of the box, and can withstand the impact and vibration generated during the crushing process. 2. In some high-end crushers, more advanced materials and manufacturing processes may also be used to improve the overall performance and life of the box.

Hammer head for crusher is one of the core parts of the hammer crusher, they are arranged on the hammer shaft of the crusher rotor, and directly strike the material when the crusher is running at high speed, and ultimately realise the crushing of the material.

Hammer shaft assembly is one of the core components in hammer crusher, which is mainly composed of main shaft, hammer head (or called cutter tooth), hanging hammer body and other components. The main shaft serves as a support and transmission component, and through its rotation drives the hammer head to impact, shear and friction on the material, so as to achieve material crushing. The function of the hammer shaft assembly is to effectively crush the large materials into the required particle size products to meet the demand for subsequent processing or utilisation.

Coal mine hammer crusher is a kind of crushing equipment specially used in coal mining industry, which mainly carries out impact, shear and friction effects on the materials through the high-speed rotating hammer head, so as to achieve the crushing of materials.
