Six major structures of multi-cylinder hydraulic cone crusher

1.1 Multi-cylinder structure

Multi-cylinder hydraulic cone crusher refers to multiple hydraulic cylinders distributed around the circumference of the frame. This structure can realize the integration of the upper and lower frames during the crushing process, as well as the retreat protection of unbreakable objects and the cavity clearing function of sudden shutdown. The hydraulic cylinder for cleaning the crushing cavity has a long stroke and is independent of liner wear. It can reduce the cleaning workload and clear the cavity quickly, thereby shortening downtime. Compared with the single-cylinder hydraulic cone crusher, there is no need to remove the connecting bolts of the upper and lower frames under the same working conditions, and the upper frame can be easily opened, which is labor-saving and convenient.
1.2 Fixed axis structure
The multi-cylinder hydraulic cone crusher adopts a separate design of the main shaft and the moving cone. The main shaft and the lower frame become a whole through a taper interference fit. In this way, the diameter of the main shaft can be designed to be large enough to withstand a large load and can crush very hard materials. materials. In addition, when replacing the crushing wall, the moving cone can be directly lifted out and the lifting height is relatively low, which is convenient for maintenance.

1.3 Hydraulic adjustment of discharge port
The size of the discharge opening is set through the PLC touch screen, and the hydraulic system is used to adjust the fixed cone lining plate, that is, the adjustment of the discharge opening is realized through the rotation of the fixed cone to rise or fall. In the process of adjusting the discharge port, the relative wear position of the fixed cone liner is also constantly changing. This can repair the out-of-roundness of the fixed cone liner caused by local wear, make the liner wear more even, and help ensure the discharge port. size to meet the particle size requirements of finished materials.

1.4 Labyrinth seal structure
The seals between the moving cone and the eccentric sleeve, and the eccentric sleeve and the frame all adopt U-shaped and T-shaped sealing structures to form a labyrinth seal, which is also called a non-contact seal. Therefore, there is no friction between each other and will not change due to environmental changes. And affect the sealing effect, durability and long life.

1.5 multi-cavity structure
In order to meet different working conditions, a variety of crushing cavity types are designed, and the coarse, medium and fine cavity types in the standard type and short head type can be interchanged. The same machine model can be selected for the same project, but coarse, medium and fine cavity types can be selected according to different processes. Except for the different cavity types, most parts are exactly the same, which reduces the type and quantity of on-site spare parts and reduces customer inventory costs.

1.6 Lamination broken
Hydraulic cone crushers generally use an optimized laminated crushing chamber. Coupled with its characteristics of large swing range, high swing frequency, and large bottom cone angle, it can achieve laminated crushing of multi-particles. During the crushing process, the weak surfaces of low-strength flake materials and blocks in the material are first crushed. As the crushing process proceeds, the degree of compaction of the material in the cavity continues to increase, and the content of fine particles increases significantly, which can make the crushing cavity uniform. Accumulate the feed material to better achieve lamination and crushing. The materials formed by laminated crushing have good particle shape and high strength. They do not need to be reshaped and can be directly supplied to the supplier's mixing station. Therefore, the sand and gravel aggregate industry currently prefers to use multi-cylinder hydraulic cone crushers.
