Product Overview

This series of spring cone crushers is a modern and efficient spring cone crusher with high-performance crushing chamber and high crushing frequency. It is an important medium and fine crushing equipment in mineral processing plants and sand and gravel production lines, suitable for medium to fine crushing operations of ores and rocks with medium hardness and above, it has the characteristics of reliable structure, high crushing ratio, and economic practicality, and is widely used domestically and internationally.

Key Advantages

Laminated crushing and good particle size

Based on the principle of laminated crushing and the concept of more breaking and less grinding, the design and development of the crushed product are cubic in shape with high content of fine particles, effectively reducing needle like materials and meeting the needs of high-quality aggregates

High overload protection efficiency

The spring safety system plays an overload protection role, providing "spring type" iron release protection for foreign objects (iron blocks), effectively reducing downtime, and integrating high swing frequency, optimized cavity shape, and reasonable stroke, which can effectively improve crushing capacity

Multiple cavity types High precision

Standard, medium, and short head types can provide optimal crushing solutions for medium, fine, and ultra fine crushing operations, and the equipment achieves digital control from steel plate cutting, bending, planing, milling to painting, with high processing accuracy

Reasonable design and good sealing

The large diameter spindle and heavy-duty main frame make the equipment sturdy and durable, and adopt a labyrinth+grease sealing form to isolate dust and lubricating oil, effectively extending the service life of sliding bearings and thrust ball bearings, and ensuring stable and reliable operation

Working Principle

The motor drives the large bevel gear at the bottom of the eccentric sleeve through a small bevel gear, driving the eccentric shaft sleeve to rotate, thereby forcing the eccentric shaft to perform periodic rotational motion below the axis, causing the surface of the crushing wall to sometimes approach and sometimes leave the surface of the rolling mortar arm, causing the material to be crushed in the crushing chamber due to compression and grinding.

Frequently Asked Questions

The spring assembly surrounds the lower frame and applies downward pressure on the adjustment ring. If tramp iron or oversize material enters the chamber, the springs compress and allow the ring to lift, releasing the obstruction. This protects internal components from damage.

Standard cone crushers have a larger feed opening and are used for medium or secondary crushing, while short-head cone crushers have a smaller feed opening and finer discharge, making them better suited for tertiary or fine crushing stages.

Yes. Spring cone crushers use a classic design with standardized components. Xingaonai stocks all critical wear parts (mantle, bowl liner, springs, eccentric bushing) and can ship globally within 3–7 business days.
