Single-Cylinder Hydraulic Cone Crusher PARTS

The following is a detailed introduction to its main components:

1. Core Wear Parts (Consumables)

These parts are directly involved in the crushing process, wear out the fastest, and require regular replacement.

● Mantle (Moving Cone Liner)

Function: Installed on the moving cone, it is the primary moving crushing component. It interacts with the concave through extrusion, bending, and shearing to break materials.

Material: Typically made of high manganese steel (ZGMn13), ultra-high manganese steel, or alloy steel with added chromium, molybdenum, etc. For extremely abrasive conditions, composite materials with embedded tungsten carbide (TIC) are also used.

● Concave (Fixed Cone Liner)

* Function: Installed in the adjustment ring bushing, it forms the crushing chamber together with the mantle and serves as the primary fixed crushing surface.

* Material: Corresponding to the mantle material, it is usually made of high manganese steel, alloy steel, or other wear-resistant materials. The mantle and concave should be replaced in pairs to ensure optimal crushing performance and energy efficiency.

● Feed Hopper Liner / Distributor

* Function: Installed at the top of the crusher's feed inlet, it evenly directs material into the crushing chamber, preventing direct impact on the upper main shaft and guard of the moving cone. It provides protection and ensures uniform material distribution.

* Material: High manganese steel or alloy cast iron.

2. Mechanical Structure and Hydraulic System Core Components

These are key components that ensure the normal operation and functionality of the crusher.

● Main Shaft Assembly

* Function: It is the core load-bearing and power transmission component of the crusher. The upper part is equipped with the moving cone and mantle, while the lower part engages with the eccentric sleeve via a cone sleeve. The rotational motion of the motor drives the main shaft to perform a gyrating movement through the eccentric sleeve.

* Material: Typically forged from high-strength alloy steel, precision-machined, and heat-treated to exhibit extremely high strength and toughness.

● Eccentric Sleeve Assembly

* Function: Fitted around the main shaft, its inner bore is an inclined eccentric hole. The motor drives the eccentric sleeve to rotate via a pulley or coupling, converting rotational motion into the gyrating movement of the main shaft.

* Composition: Includes the eccentric sleeve body, lower large gear, etc.

● Frame Bushing / Main Frame Sleeve

Function: Press-fitted into the center hole of the main frame, it provides support and positioning for the rotation of the eccentric sleeve, ensuring motion accuracy.

● Main Shaft Copper Sleeve / Cone Sleeve

* Function: Installed between the main shaft and the eccentric sleeve, it acts as a critical friction bushing. When tramp iron or other non-crushable objects pass through the crusher, the immense force pushes the main shaft downward, compressing the hydraulic cylinder to achieve hydraulic cavity clearing and tramp iron protection. It is the core component enabling the safety function of the single-cylinder structure.

* Material: High-strength brass or bronze.

● Hydraulic Cylinder Assembly

* Function:

Adjust Discharge Opening: By injecting or draining oil from the cylinder via the hydraulic station, the main shaft assembly is raised or lowered, precisely adjusting the size of the discharge opening.

* Tramp Iron Protection: When non-crushable material enters the crushing chamber, the pressure surges, and the hydraulic cylinder automatically releases pressure, allowing the discharge opening to widen and expel the foreign object before resetting automatically.

* Cavity Clearing: If the crusher becomes clogged, the hydraulic system can be operated to raise and lower the moving cone, breaking up or expelling the material in the chamber.

● Main Frame

* Function: Serves as the base of the entire crusher, supporting all other components and withstanding immense crushing forces. It requires extremely high rigidity and strength.

* Material: Welded from high-strength steel plates, with reinforced critical areas.

● Drive Unit

* Composition: Includes the motor, pulley, V-belts, coupling, etc., responsible for transmitting the motor's power to the eccentric sleeve.

● Lubrication System

Composition: Includes oil pump, oil tank, filters, cooler, pipelines, and instruments (pressure gauge, temperature gauge). It supplies clean, temperature-regulated lubricating oil to friction pairs such as the eccentric sleeve, frame bushing, and main shaft copper sleeve, ensuring long-term operation of the equipment.

● Hydraulic System

Composition: Includes hydraulic station (motor, oil pump, valve block), accumulator, hydraulic cylinder, and pipelines. It controls discharge opening adjustment, tramp iron protection, and cavity clearing functions.
