What causes cone crusher seal failure



What causes cone crusher seal failure?


Due to the dust produced in the process of cone crusher, the corresponding sealing device is usually required. However, sealing failure will occur in the production.Reasons for seal failure are as follows:

1. Sealing parts are damaged
The seals wear serious. If the gap between the cone crusher parts becomes smaller, the sealing parts will be severely damaged by extrusion deformation.Or in the replacement of part of the wear parts, due to the replacement cycle of the seals and friction parts of the wear cycle is not consistent, the degree of old and new, so that the rubber ring of the sealing pressure increase, local deformation caused by the damage of the seals.

2. Aging of seals.Rubber seal in use by the oil, temperature, time factors, coupled with improper selection of materials to make the sealing ring, easy to appear aging phenomenon, make the sealing ring body elastic, sealing state changes, resulting in equipment sealing failure.

3. Deformation of seals
Stress deformation.When the cone crusher the broken wall and the mortar wall breaks the ore, the strong crushing force causes the body to tilt or vibrate, the seal is very easy to deviate from the original motion track and deform, so that the original sealing state changes, resulting in equipment sealing failure.

4.Improper installation.When the cone crusher is in installation, maintenance and replacement of seals, due to incorrect installation, partial deformation of seals occurs, leading to equipment seal failure.

5. Poor lubrication.The friction part is prone to metal particles and ore dust mixing, and there are long-term work in the high temperature environment, so that the lubricating oil deterioration, poor liquidity, seal local resistance increase and lead to deformation.

Operation of Jaw Crusher

图片
Operation Instructions of Jaw Crusher 1.The preparation before starting: (1) Inspect each bearing to ensure whether it lubricates well, and whether there is enough lubricating grease on the toggle plate joints and bearing inners. (2) Check carefully whether all fasteners are totally fastened. (3) Check whether the drive belt is under good condition, and change the belt if any damages can be found. When there is grease contamination on the belt or bell wheel, it can be clean up with a clean dishcloth. (4) Check whether the protective device is under good condition, if there are any unusual events and safety hazards conditions, should correct them and report. (5) Check whether there are any ore or other impurities inside the crushing cavity. 2.The starting of the crusher (1) After inspecting the machine and transmission parts are under good condition, the machine may starts. (2) This machine can only start under empty load conditions. (3) After having started the machine, shut down the

What factors affect the output of cone crusher

What factors affect the output of cone crusher There are three main factors influencing the productivity of cone crusher : the number of times of the swing of the cone;The length of the parallel crushing area;The size of the engagement Angle.These three aspects directly determine the output of cone crusher. 1.the number of times of the swing of the cone The swing times of the crushed cone is one of the key factors affecting the crusher productivity. Because of the limitation of the meshing Angle of the crushing cavity and the parallel ore discharge area, the crushed ore is discharged along the taper inclined plane mainly by gravity and vibration.When the number of spindle rotation increases, the ore is easy to be discharged, but the number of rotation is too high, which is not conducive to ore discharge, sometimes resulting in faster speed and unable to produce.Therefore, the number of swing of the broken wall has a certain constraint on the improvement of productivity. 2.The l
