The spring cone crusher, also known as the Simons cone crusher, is a mechanical device that utilizes the principle of layered crushing to achieve fine crushing of materials. It is suitable for medium-hard and hard materials with a compressive strength not exceeding 350 MPa, such as iron ore, copper ore, granite, basalt, and limestone.

Its core structure includes a frame, transmission device, moving cone, fixed cone (adjusting ring), eccentric sleeve, spring safety device, and hydraulic system. The spring safety system is an overload protection device. It provides “spring-type” overload release protection against foreign objects (iron blocks). Under normal operating conditions, the spring cone crusher equipment has a fault-free operation rate exceeding 95%.

Depending on the type of crushing chamber, spring cone crushers for sale can be divided into standard type (medium crushing), medium type (fine crushing), and short-head type (ultra-fine crushing) to meet different particle size requirements.

Spring Cone Crusher Working Principle

The main structure of a high-efficiency spring cone crusher includes a frame, transmission device, moving cone, fixed cone, and eccentric sleeve. It utilizes the principle of layered crushing to reduce the output of needle-like and flaky materials.

During operation, the motor drives the eccentric sleeve to rotate via a V-belt and drive shaft. The eccentric bushing inside the eccentric sleeve generates an eccentric torque, driving the moving cone to perform a gyratory motion (revolution + slight rotation). The moving cone is suspended above the main shaft. A crushing chamber is formed between the moving cone liner (crushing wall) and the fixed cone liner (jaw wall).

Stone material falls into the crushing chamber from the upper feed hopper and gyrates continuously with the moving cone. When the moving cone approaches the fixed cone, the material is crushed through compression, splitting, and grinding. When the moving cone moves away from the fixed cone, material smaller than the discharge opening falls downwards under its own weight and is discharged from the bottom of the machine. Larger pieces of material continue to be crushed at the top, gradually moving downwards until they are discharged at the appropriate particle size.

The discharge opening is adjusted manually by adjusting shims or rotating the adjusting ring when the machine is stopped. Material blockage requires manual clearing of the cavity.

Features of High Efficiency Spring Cone Crusher

• Reasonable structure. Excellent crushing principle and technical parameters. Reliable operation and low operating costs.
• High crushing force, high production efficiency, and high output.
• Reliable spring safety system provides safe and effective overload protection.
• Two crushing chamber structures to adapt to a wide range of product particle size requirements.
• Manual hydraulic adjustment of the discharge port for easy and labor-saving operation.
• Positive pressure dustproof system effectively prevents dust and other debris from entering the equipment and oil tank, avoiding lubricating oil contamination.

Spring Cone Crusher Equipment Applications

Spring cone crushers are primarily used for secondary crushing of ores and rocks of medium to high hardness, while the short-head chamber can be used for tertiary fine crushing. They are suitable for limestone, granite, and river pebbles. High-efficiency spring cone crushers are used to produce ordinary building aggregates but are not suitable for large-scale continuous production of high-standard, high-quality sand and gravel. They are mostly used in small- to medium-sized sand and gravel plants and small mines.
