Product Overview

The X Series Primary Gyratory Crusher is designed for continuous primary crushing in large mines, hard-rock quarries and high-capacity aggregate plants. It processes run-of-mine ore and blasted rock before secondary crushing, grinding or material handling. Multiple chamber configurations and model sizes are available to match different feed openings, capacities and product-size requirements.

Key Advantages

High-Capacity Primary Crushing

The X Series Primary Gyratory Crusher provides continuous crushing and discharge for large mines, hard-rock quarries and aggregate plants. The available models offer nominal capacities from 310 to 3,200 tph.

Hydraulic CSS Adjustment

The hydraulic system raises or lowers the main shaft to adjust the closed-side setting. This helps control product size and compensate for mantle and concave wear.

Hydraulic Overload Protection

When tramp metal or another uncrushable object enters the chamber, the hydraulic system helps increase the discharge opening and protect critical components.

Heavy-Duty Structure

The heavy-duty main frame, spider assembly, main shaft, mantle, concaves and eccentric assembly are designed for continuous primary-crushing loads in mining and quarrying applications.

Controlled Lubrication System

The forced-circulation lubrication system supplies oil to critical bearings and bushings. Oil-temperature, pressure and flow monitoring help protect the crusher during continuous operation.

Multiple Models and Chamber Configurations

Different models and crushing chambers are available for various feed sizes, capacities and discharge requirements. Model selection should consider the complete process rather than nominal capacity alone.

Working Principle

Run-of-mine ore or blasted rock enters the crushing chamber between the moving mantle and the stationary concaves. The eccentric assembly causes the main shaft and mantle to move in a continuous gyrating path. Material is compressed when the mantle moves toward the concaves and moves downward when the crushing gap opens. The material is progressively reduced until it is small enough to leave through the bottom discharge opening. Product size is mainly controlled by the closed-side setting (CSS), chamber profile, feed gradation and material properties. The hydraulic system adjusts the main-shaft position to control the CSS and compensate for liner wear. For stable operation, material should be fed continuously and distributed evenly around the crushing chamber.

Frequently Asked Questions

Unlike a jaw crusher, which uses a reciprocating motion, a gyratory crusher uses a continuous gyrating motion of a cone-shaped mantle inside a concave bowl. This allows for continuous crushing (not intermittent), resulting in higher throughput, lower energy consumption per ton, and more consistent particle shape.

Limited moisture may be acceptable, but excessive clay or sticky fines can cause buildup, bridging and reduced capacity. Moisture and clay content should be evaluated before equipment selection.

Key maintenance items include the main shaft and mantle wear inspection, eccentric sleeve lubrication, spider bearing checks, and monitoring the hydraulic or mechanical adjustment system. A structured preventive maintenance program significantly extends machine lifespan.

Yes. Due to its large size and high operating forces, a gyratory crusher requires a solid reinforced concrete foundation specifically designed to its load specifications. Xingaonai provides detailed foundation drawings and installation engineering support as part of the project package.
