Innovative design highlights of CH890i cone crusher Applications

Metal ore processing

This crushing equipment is designed for the secondary and fine crushing of hard metal ores such as iron ore, copper ore, tungsten and molybdenum ore, and is particularly suitable for the secondary crushing of large mines. Its powerful processing capacity is up to 950 tons/hour (closed circuit conditions), which can significantly increase the proportion of fine-grained products (-12mm) to 60%, which greatly optimizes the subsequent mineral processing efficiency. Through precise crushing control, the equipment can ensure uniform ore particle size and provide high-quality raw materials for subsequent smelting processes.

Non-metallic ore crushing

This equipment also performs well in the crushing of high-hardness rocks such as granite, sandstone, and quartzite. It can meet the large-scale needs of quarries and sand and gravel production, ensuring that the crushed rock particle size meets the standards of construction, road construction and other fields. Through the optimized crushing chamber design and efficient crushing mechanism, the equipment can easily cope with the challenges of high-hardness rocks, improve production efficiency and reduce operation and maintenance costs.

Sand and gravel aggregate production

In the field of sand and gravel aggregate production, this crushing equipment is widely used in the secondary and fine crushing of construction sand and concrete aggregates. When used in conjunction with screening equipment, it can achieve closed-loop circulation and ensure the improvement of the qualified rate of finished products. Whether it is common materials such as river pebbles and limestone, or other materials with special requirements, the equipment can provide stable crushing performance and support the efficient operation of the sand production line.

Cement and refractory materials

In the cement production process, the crushing equipment can crush raw materials such as limestone and coal gangue to provide intermediate products with uniform particle size for cement production. At the same time, it can also process waste such as metallurgical slag and refractory waste to achieve resource recycling. This feature not only helps to reduce production costs, but also reduces environmental pollution and enhances the social responsibility of enterprises.

Metallurgical raw material processing

For the crushing of metallurgical raw materials such as iron ore and copper ore, the equipment can also meet the medium crushing needs before smelting. It can handle high-hardness materials (≤450MPa), such as alloy waste, slag, etc., to ensure that the particle size of the crushed materials meets the requirements of the smelting process. In addition, the equipment is also suitable for the fine crushing of chemical materials such as glass raw materials and corundum to ensure uniform and stable particle size and provide high-quality raw materials for subsequent processes.

This automatic adjustment function not only improves the operating stability of the equipment, but also reduces the downtime caused by failure.

Innovative design highlights of CH890i cone crusher Working Principle

As the core power source of the crushing equipment, the motor drives the eccentric sleeve to rotate through a precisely designed bevel gear set. This rotational action in turn drives the crushing cone (also known as the moving cone) to perform periodic pendulum motion around its center line. This motion mode is designed to achieve efficient and stable crushing operations. Under the action of the eccentric mechanism, the moving cone will alternately approach and move away from the fixed cone (also known as the mortar wall). This alternating motion forms a continuously changing crushing chamber space, providing a sufficient crushing environment for the material. When the moving cone approaches the fixed cone, the material is strongly squeezed; and when the moving cone moves away from the fixed cone, the material is impacted and bent, thereby achieving crushing. This composite crushing mechanism enables the material to be refined more effectively.
In the crushing chamber, multi-particle materials will form a laminated crushing state. In this state, large particles will be crushed first and gradually refined into smaller particles. This crushing method not only improves the yield rate, but also significantly reduces energy consumption, making the entire crushing process more economical and efficient. The crushed material will be discharged smoothly from the bottom of the crushing chamber under the action of gravity. This design ensures the continuity and stability of the crushing operation. At the same time, springs or hydraulic systems are cleverly configured inside the equipment. When the equipment encounters an overload, these systems will automatically discharge foreign matter through the displacement of the support sleeve, thereby effectively protecting the core components from damage. In order to meet different crushing needs, the equipment also provides a high degree of flexibility. Users can change the shape and size of the crushing chamber by adjusting the movement parameters of the eccentric sleeve, such as rotation speed, swing amplitude, etc., so as to control the particle size of the discharge. In addition, replacing the fixed cone or dynamic cone liner of different specifications can further adjust the crushing effect to adapt to various complex crushing scenarios.
