Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of solid waste aggregate manufacturing, and particularly to a cone crusher. BACKGROUND

[0002] In the crushing process of solid waste aggregate, the cone crusher plays a crucial role. The cone crusher is a device suitable for fine crushing and superfine crushing of hard rock, ore, slag and other machine-made sand raw materials in the dry sand making process. In the extrusion process of the machine-made sand raw materials, the machine-made sand raw materials are subjected to a huge force and are extruded to the critical stress of the materials to achieve the purpose of crushing. The cone crusher is divided into four categories: spring cone crusher, mill cone crusher, hydraulic cone crusher and composite cone crusher. Among them, the hydraulic cone crusher is divided into ordinary PY cone crusher, Simons cone crusher, composite cone crusher, standard hydraulic cone crusher, single-cylinder hydraulic cone crusher and multi-cylinder hydraulic cone crusher according to the type.

[0003] In the production process of the single-cylinder hydraulic cone crusher, a large amount of dust is usually generated. The dust is raised during the process of the machine-made sand raw materials entering and leaving the single-cylinder hydraulic cone crusher, thereby polluting the workshop environment. In addition, due to factors such as excessive feeding, poor lubrication and bearing wear, the inner cone sinks after long-term use of the single-cylinder hydraulic cone crusher, which reduces the gap of the crushing cavity and causes the material to be stuck. The crushed stone is stuck in the internal equipment, which makes it difficult to perform subsequent operations. At the same time, it is easy to cause damage to the equipment parts. Although it can be repaired after shutdown, it greatly affects the efficiency of the operation and needs to be improved. CONTENT OF THE UTILITY MODEL
