Description

[0002] The main purpose of ore crushing is to crush ore from the natural state of coarse particles into smaller particles, which is convenient for subsequent processing and extraction of useful mineral components. Ore is generally crushed into a certain size of crushed material for subsequent smelting, purification and other physical and chemical processing processes, which not only increases the surface area of the ore, promotes the release of useful minerals, but also improves the mineral recovery rate and resource utilization efficiency. Common crushing equipment includes a jaw crusher, which works by the relative movement of two jaw plates to crush ore. The fixed upper jaw and lower jaw are fixed on the frame, and the movable jaw can swing under the upper jaw. When the ore passes through the crushing cavity, it is gradually reduced under the alternating extrusion, impact and friction of the two jaw plates, and finally discharged from the lower discharge port.

[0003] When the ore enters the crushing cavity at a high speed, the ore will first collide with the jaw plate and the crushing cavity wall of the crusher. Due to the high kinetic energy of the ore, these collisions will produce strong impact force. Strong impact force will cause the structural parts of the equipment to bear greater mechanical load, increasing the risk of wear and damage. This frequent impact will cause fatigue, cracks and even breakage of the crusher parts, thereby shortening the service life of the equipment. Therefore, a crushing equipment for ore crushing is designed. UTILITY MODEL CONTENTS
