Spring cone crusher Introduction

Spring cone crusher is suitable for crushing various of mid-hard and above mid-hard ores and rocks.This crusher has advantages of reliable structure,high productivity,easy adjustment and less cost in operation.The spring release system is also called overload protection system that allows oversized stone to pass through the crushing chamber without damage the crusher.It uses dry oil and water as sealing method,which separates plaster powder and lubricant,guarantee lubrication oil clean.The type of crushing chamber depends upon the feeding size and finished product size. The standard head model is applied to the medium crushing,the medium head model is applied to the medium and fine crushing,and the short head model is applied to the fine crushing.

Components:

The spring cone crusher mainly consists of a frame, transmission, hollow eccentric shaft, cup-shaped bearing, crushing cone, adjusting device, adjusting sleeve, spring, and hydraulic station for adjusting the discharge opening.
When the spring cone crusher is working, the motor drives the eccentric sleeve to rotate via a horizontal shaft and a pair of bevel gears. The crushing cone's axis of rotation, forced by the eccentric sleeve, undergoes a gyratory motion, causing the crushing wall surface to alternately approach and move away from the jaw wall surface. This results in the ore being continuously compressed and bent within the crushing chamber, thus being crushed.

Working Principle:

When the spring cone crusher is in operation, the motor drives the large bevel gear at the bottom of the eccentric bushing via a hydraulic coupling and a small bevel gear, causing the eccentric bushing to rotate. This rotation makes the cone perform a gyratory swinging motion, thereby crushing the materials. The main shaft of the crusher remains stationary, merely supporting the spherical bearing tile and bearing the crushing force. Since the main shaft of the crusher remains immobile while the eccentric bushing transmits the crushing force, this structure can withstand substantial crushing forces, making it highly suitable for fine and ultra-fine crushing, as the crushing forces involved in ultra-fine crushing are extremely high. It is anticipated that the product size distribution (for ultra-fine crushing liners) can reach 50-80% passing in an open-circuit operation (varying depending on the material properties). This crusher is applicable for the tertiary crushing stage or the quaternary crushing stage in mineral processing plants of metal mines, as well as for building materials or non-metallic mines and civil engineering projects, particularly in areas where the supply of natural sand required for civil engineering is insufficient.

Product Features:

1. Increased eccentricity to enhance processing capacity.

2. Accelerated speed and increased power to improve crushing fineness.

3. Elevated the gyratory center of the moving cone and optimized the chamber design.

4. Thickened liner plates to extend service life.

5. Replacement of hydraulic pushrod devices with hydraulic motors for precise and continuous adjustment of the discharge opening, and the ability to disassemble the fixed cone assembly within 10 minutes.

6. High output and high content of fine ore.

7. Key components are made of high-strength materials with appropriate weight increases for better reliability.
