Cone crusher is a very important equipment in the crushing production line, and it is the main equipment for dealing with the secondary crushing stage, so which part is the crushing in the cone? It is a moving cone, and the moving cone is an important part of the cone crusher. It needs to be used in conjunction with a combination of bolts, spherical bearings, and upper and lower bushings. It is inevitable that it will be worn out during the production process. Here are the reasons why a damaged motorized cone is damaged:
1. Unbalanced force of the moving cone
When the cone crushing electric cone works, the main force it bears is the inertia force of the cone, the self-weight of the movable cone, the reaction force of the spherical bearing, the reaction force of the eccentric bushing, and the
cone crushing If the resultant force of these forces is not zero, the force of the moving cone will be unbalanced, which will cause excessive vibration of the equipment and damage the moving cone.
2. Poor contact surface
The movable cone of the cone crusher is supported on the spherical bearing pads of the spherical housing. When the spherical bearing pad is worn or there is a quality problem, it will cause the movable cone to move downwards and its supporting contact surfaces will not be in good contact, which will lead to increased friction of the movable cone. It was badly damaged.
3. The equipment is overloaded
Based on the production policy of more crushing, less grinding, reducing costs and increasing efficiency, many manufacturers will increase the productivity of
cone crushers by further reducing the size of qualified ore, increasing the amount of ore, etc., resulting in long-term overload operation, which will further increase the operating cone. Over time, the burden on the ministry will eventually lead to damage to the movable cone.
4. Pine cone
Since there is no preload detection tool between the cone head and the spindle thread, maintenance personnel can get to grips with the actual work. After the stop gear is meshed with the gear of the bevel head, the preload cannot meet the technical requirements. When the cone crusher is operating under load, the cone head becomes loose, which causes wear and tear on the gears and movable cones.
5. The moving cone is impacted more frequently
When the non-crushed material enters the main body of the
cone crusher, the uneven feed of the feed port or the damage of the cone crusher lock cylinder will make the shock load of the movable cone more frequent. When the instantaneous impact load approaches the strength limit of the active cone, its fragile parts will be damaged, resulting in microcracks. Under the long-term action of heavy and alternating loads, the microcracks gradually expand, and eventually damage the moving cone.
6. Improper spring compression
After the cone crusher is put into use, if there is severe vibration, low production efficiency, large product particle size, etc., it indicates that the compression force of the cone crusher is insufficient. To ensure smooth production, some manufacturers readjust the amount of compression of the springs. Although the compressive force of the cone crusher increases, it increases the workload of the moving cone and damages the moving cone.
