Description

Technical Field

[0001] The utility model belongs to the technical field of crushers, and particularly relates to a phosphate ore crushing device. Background Art

[0002] A crusher is a mechanical device used to crush materials into smaller particles. It is usually used to process materials with various hardnesses and brittlenesses, such as ores, coals, rocks, construction wastes, etc. The working principle of the crusher is to crush or break the materials by applying pressure or impact force, so as to obtain the required particle size. Crushers are widely used in industries such as mining, construction, chemical engineering, and metallurgy, and are one of the key equipment indispensable in the production process.

[0003] In mining production, the structure of the impact crusher hammer is simple and the efficiency is relatively high. For example, an impact crusher disclosed in the utility model patent with the authorized patent publication number of CN220443971U includes a housing. An inlet is provided on one side of the housing. The housing is located on a fixed plate. A crushing chamber is formed inside the housing. A crushing component and a vibration component are arranged inside the housing. The crushing component includes a rotor assembly. The rotor assembly is fixedly installed with plate hammers. A counter plate is fixedly installed at the top of the housing and at a position adapted to the inlet. A front lining plate is arranged on one side of the rotor assembly. The crushing of the stone materials is completed by the cooperation of the rotor and the counter plate. However, the lining plate of this impact crusher hammer is generally connected to the top housing. During the crushing process, the lining plate is impacted. If the structural strength of the housing is not high, it is easy to cause the deformation of the housing, resulting in an increase in the gap between the crushing lining plate and the rotor, affecting the discharging accuracy. At the same time, after the housing of the crusher is deformed during the maintenance process, it is not convenient for maintenance. To solve the above problems, a phosphate ore crushing device that can improve the structural strength of the crusher and is convenient for maintenance is needed. Summary of the Invention
