Description

Technical Field

[0001] The utility model relates to the technical field of crushers, in particular to a crusher used for mining mechanical equipment. Background Art

[0002] The crusher used in mining machinery and equipment is a kind of equipment used to crush large pieces of ore or ore fragments. It is usually composed of a feed port, a discharge port, a screen and other components. When the ore enters the crusher through the feed port, the crushing roller will rotate to crush the ore into smaller particles. The crushed ore is discharged from the discharge port through the screen. After reaching the particle size requirement, it can be used in the subsequent mineral processing. The crusher used in mining machinery and equipment is often used in mining, metallurgy, construction, chemical industry and other industries to crush ores and rocks of various hardness.

[0003] When using the crushers used in some existing mining machinery and equipment, the ore is usually placed directly into the crushing bin so that it is in direct contact with the crushing roller. However, when some large-sized ores are directly poured into the crushing bin, due to their weight, they will accelerate and hit the crushing roller while pouring, which may cause the crushing roller to be damaged. Therefore, this problem needs to be solved. Utility Model Content
