Cone crusher is a crushing machine suitable for raw materials in metallurgy, construction, road construction, chemistry and silicate industry. According to the difference of crushing principle and the particle size of products, they are divided into many models. Crushers are widely used in mines, smelting, building materials, highways, railways, water conservancy and chemical industries and many other departments. The cone crusher has the advantages of high crushing ratio, high efficiency, low energy consumption and uniform product size. It is suitable for medium crushing and fine crushing of various ores and rocks. The models are mainly divided into SMG series, spring type and HPC series. Their working principle and structure are introduced respectively. The development history, working principle, composition, influencing factors, technical advantages, operation matters, common faults and maintenance of cone crusher are introduced in detail. Do you understand the three kinds of stuck phenomena and causes of the cone crusher? Let's take a look at it.
1, blocking stuck
1, cone crusher feeding too much, or the nature of the material does not meet the requirements, resulting in blocking cone crusher, will make the crusher working current too large, circuit automatic protection and stop the machine, and may even occur cone crusher stuck and forced to stop the situation.
2. When iron or other unbreakable material enters the crushing chamber of the cone crusher, it will cause the plugging of the cone crusher and even the stuck of the equipment.
2, spindle fracture stuck
, improper use of the cone crusher is one of the main reasons for the main shaft fracture, such as in order to achieve the required discharging fineness when continuously tightening the discharging port, if there is something that can not be broken into the crushing chamber, the main shaft of the cone crusher clean impact, resulting in fracture of the main shaft stuck.
2, on the other hand, when the cone crusher is in overload operation for a long time, although there is overload protection device, but can not completely avoid damage to the equipment, the main shaft is prone to fracture leading to equipment jam.
3. The moving cone and the adjusting sleeve are stuck to
1. When the cone crusher runs with load, the locking failure is caused by the loss of pressure of the hydraulic station, and the adjusting sleeve will rotate with the moving cone. If the post personnel do not discover and deal with in time, it will cause the phenomenon of adjustment jacket stuck, leading to the cone crusher shutdown.
2. The cause of the adjustment sleeve jamming may be the poor thread lubrication, the seal wear of the adjustment cap or dust cover, the scratch of the adjustment sleeve and the support sleeve, or the long overload of the cone crusher. Eight hundred and eighty-eight thousand one hundred and eleven
