Multi-cylinder Hydraulic Cone Crusher

As a new generation of hard rock crushing equipment, the multi-cylinder hydraulic cone crusher innovatively adopts the principle of lamination crushing. The finished product has a cubic shape, and the content of needle-like and flaky materials is reduced by more than 30%, which perfectly meets the high standards of construction aggregates. The equipment integrates hydraulic locking, overload protection and intelligent cavity cleaning technologies. When encountering foreign objects such as iron blocks, it can automatically release and reset without the need to stop the machine, reducing the failure rate by 60% and significantly improving the continuity of operation.

Working principle of Multi-cylinder Hydraulic Cone Crusher

The electric motor drives the horizontal shaft to rotate, which directly transmits power to the gear. The gear drives the eccentric sleeve to rotate around the main shaft, causing the movable cone to swing and rotate. Copper bushings are embedded between the main shaft and the eccentric sleeve, and between the eccentric sleeve and the movable cone, functioning as bearings. The discharge opening size is adjusted by rotating the fixed cone. Six hydraulic cylinders mounted externally on the main unit hold the fixed cone, providing overload protection and cavity clearance functions. The complete crusher assembly comprises the main unit, lubrication system, and electrical control system.

The multi-cylinder hydraulic cone crusher employs the laminated crushing principle, with the specific working process as follows:

Startup: After the motor starts, the drive belt, transmission shaft, and bevel gear pair drive the eccentric sleeve to rotate.

Rotary-swing motion: The rotation of the eccentric sleeve drives the movable cone to perform a rotary-swing motion, with the movable cone's rotational trajectory forming an ellipse.

Crushing Process: Material enters the crushing chamber through the feed opening. The alternating convergence and divergence of the moving and fixed cones subject the material to squeezing and grinding forces, achieving fragmentation.

Discharge: Crushed material passes through the gap between the fixed and moving cones, exiting the chamber via the discharge opening.

Application areas

 

The multi-cylinder hydraulic cone crusher is widely used in medium and fine crushing scenarios for ores, particularly in demanding environments requiring high precision of finished products and continuous production. Its advantages include high efficiency, excellent finished particle shape, reliable hydraulic protection, and suitability for medium to high hardness materials. Key applications are as follows:

Metal Mining and Beneficiation Industry

Serves as the core medium-fine crushing equipment following primary jaw crushing, processing metal ores with Mohs hardness levels 5-8 to meet feed size requirements for beneficiation equipment.

Construction Aggregate and Sand-Gravel Production Industry

Replaces traditional equipment as the core of premium aggregate production lines, handling hard raw materials to produce sand and gravel meeting high-quality infrastructure demands.

Non-metallic mineral processing

Handles low-to-medium to medium-high hardness characteristics of non-metallic minerals, controlling particle size and minimizing over-crushing to meet downstream building materials and chemical industry demands.

Metallurgical and chemical industries

Used for furnace charge pre-treatment and raw material crushing prior to purification, employing stable crushing and hydraulic protection to prevent equipment damage from impurity overload.

Hydraulic Engineering and Road Construction

Provides high-strength aggregates with stable gradation. Features like iron protection and rapid chamber clearance support continuous project operations.

Construction Waste Recycling

Processes construction debris containing minor metal impurities, crushing it into recycled aggregates to comply with resource recovery policies.
