Why Multi cylinder cone crusher is popular?

The world's first multi-cylinder hydraulic cone crusher was born in the 1990s. It was officially launched by Metso Nordberg after about 10 years of research and improvement on Ominicone. The first large-scale use of multi-cylinder hydraulic cone crushers in China was in the Three Gorges artificial stone project in 1996, when a total of 2 sets  multi-cylinder hydraulic cone crushers HP300 and 2 sets multi-cylinder hydraulic cone crushers HP500 were introduced. Since then, multi-cylinder hydraulic cone crushers have been gradually applied in large-scale mining industries and sand and gravel aggregate industries in China.

Working principle

The motor drives the transmission shaft to rotate, and the transmission shaft drives the eccentric sleeve to rotate around the eccentric shaft through large and small bevel gears, and then the eccentric sleeve drives the moving cone to swing eccentrically, thereby achieving continuous extrusion and crushing of stones.

Product features

1. The structural strength is improved by separating the moving cone from the main shaft, thickening the main shaft and fixing it, and only the moving cone does a swinging motion.
2. Increase the main shaft diameter, moving cone diameter, feed port size and eccentricity, speed up the moving cone swing frequency, increase the number of crushing times of material particles in the crushing chamber, and thus improve production capacity; at the same time, the crushing chamber adopts a slow cone design to reduce the discharge particle size and increase the content of fine materials in the finished material.
3. The hydraulic motor rotates the fixed cone to quickly adjust the discharge port or remove the fixed cone, and the discharge port can be adjusted under load.
4. The adjustment ring is locked by a hydraulic cylinder, which is reliable and easy to maintain.
5. Multiple hydraulic cylinders around the locking replace springs to provide locking, overload protection and cavity clearing.
6. The highly automatic control system controls the hydraulic system for adjustment to maximize the performance of the equipment.
7. The lamination effect is excellent. Under the condition of full cavity full of feed, the fine material content in the discharge is the highest (compared with single cylinder and Simmons cone crusher).
8. A variety of crushing chamber types can be selected, suitable for use under different working conditions.

Summary

The design of high speed, large swing frequency, large eccentricity and slow cone, combined with the condition of full cavity and center feeding, enables the multi-cylinder hydraulic cone crusher to maximize the effect of "laminated crushing", achieving the highest proportion of fine materials in the finished material (compared with spring cone crusher and single-cylinder hydraulic cone crusher, under the same material conditions), and is more suitable for fine crushing (three crushing). Therefore, multi-cylinder hydraulic cone crusher is increasingly favored by users in sand and gravel production lines.
