Gyratory crusher Parts

The main components include:

I. Core Wear Parts (Consumables)

These components directly participate in crushing and require regular replacement.

1. Concave

Function: Fixed to the inner wall of the crusher frame, forming the crushing chamber. They are the primary fixed crushing surface.

Material: High manganese steel (Mn14%–Mn22%), alloy steel, or TIC (tungsten carbide insert) reinforced composites.

2. Mantle

Function: Mounted on the main shaft, it is the primary moving crushing component that gyrates against the concave to crush materials.

Material: High manganese steel, ultra-high manganese steel, or TIC-reinforced composites.

3. Spider Arm guard/ Spider Rim Liners

Function: Protect the spider assembly from wear and material buildup.

Material: High manganese steel or wear-resistant alloy steel.

II. Mechanical Structure & Hydraulic System Components

4. Main Shaft Assembly

Function: The core component that transmits crushing force and gyratory motion.

Composition: Main shaft, crushing head, and core assembly.

5. Eccentric Assembly

Function: Driven by the motor, it converts rotational motion into the gyratory motion of the main shaft.

Composition: Eccentric bushing, gear, and drive shaft.

6. Top Shell & Bottom Shell

Function: Form the main structure of the crusher, supporting all internal components and withstanding crushing forces.

Material: High-strength steel plate with reinforced welding.

7. Hydraulic Adjustment System

Function:

Adjust Discharge Opening: Controls the crusher's discharge setting.

Overload Protection: Releases crushing force automatically when non-crushable material enters.

Composition: Hydraulic cylinder, accumulator, pump, and control valves.

8. Dust Seal System

Function: Prevents dust from entering the lubrication system, ensuring normal operation of bearings and bushings.

Composition: Seal rings, dust collars, and lubrication channels.

9. Drive Assembly

Function: Transmits power from the motor to the eccentric assembly.

Composition: Motor, V-belts, pulley, and coupling.

10. Lubrication System

Function: Provides continuous lubrication to bearings, bushings, and gears.

Composition: Oil pump, oil tank, cooler, filters, and monitoring instruments.

III. Auxiliary Components

11. Feed Distributor / Feed Hopper

Function: Evenly distributes material into the crushing chamber.

Material: Wear-resistant steel plate.

12. Discharge Trough / Chute

Function: Guides crushed material to the next process stage.

Material: Wear-resistant steel plate with liners.

Key Features & Advantages

* Superior Wear Resistance

Mn18–Mn22% concaves last 2–3x longer than standard steel in high-abrasion crushing.

TIC inserts provide 50%+ longer lifespan in ultra-hard rock applications.

* Optimized Crushing Performance

Precision-engineered profiles ensure consistent particle size output.

Balanced design reduces vibration and extends bearing life.

*Easy Maintenance & Replacement

Modular concave segments allow partial liner changes without full disassembly.

Bolt-on liners simplify installation and reduce downtime.

* Industry-Specific Solutions

Mining: High-Mn or TIC-enhanced concaves for iron/copper ore.

Quarrying: Custom chamber designs for granite/basalt.
