The cone crusher has undergone several generations of changes and continuous improvement from its advent to its wide application. The current major types of cone crushers are mainly derived from the gently inclined cone crushers and compression gyratory crushers. Continuous improvement of performance, continuous improvement of structure, and continuous optimization of design make the application range of cone crushers wider and wider. At present, cone crusher has become the "nemesis" of hard metal ores. This article will introduce the application status of this equipment in many sectors such as mining, smelting, building materials, highways, railways, water conservancy and chemical industry.

When the cone crusher is working, the motor drives the large bevel gear at the bottom of the eccentric sleeve through the hydraulic coupling and the small bevel gear to rotate the eccentric sleeve, causing the cone to swing and crush the material. The main shaft of the crusher does not move, but only supports the spherical tiles to withstand the crushing force. Since the main shaft of the crusher does not move and the eccentric sleeve transmits the crushing force, the structure can withstand greater crushing force. Therefore, the cone crusher is suitable for crushing hard metal ores. It is especially suitable for fine crushing and ultra-fine crushing because of the crushing force of ultra-fine crushing. Is very big.

The cone crusher combines higher speed and stroke, which greatly improves the rated power and throughput of the equipment, and improves the crushing ratio and production efficiency. The hydraulic cone crusher is a combination design of crushing stroke, crushing speed and crushing cavity shape. In addition, all parts of the cone crusher are protected against wear, and are also made of materials with strong impact resistance and high wear resistance through good technology. All these make the cone crusher unique in crushing hard metal ores. Advantage.

The cone crusher is suitable for the third or fourth stage of crushing in metal mine concentrators; suitable for medium and fine crushing of various ores and rocks with medium hardness and above; suitable for building materials or non-metallic mines and civil engineering, Especially in areas where the supply of natural sand for civil engineering is insufficient. The cone crusher adopts the special crushing cavity designed by the principle of inter-particle lamination and the matching speed to replace the traditional single-particle crushing principle to achieve selective crushing of materials; only the fixed cone liner and the movable cone liner need to be replaced , The crushing cavity shape can be arbitrarily changed from the standard ultra-thick cavity type to the short-end ultra-fine cavity type to meet the requirements of a wide range of product particle sizes. The unique design of the crushing cavity has a great advantage in the crushing of hard ores.

At present, the comprehensive utilization rate of mine resources in my country is relatively low. Except for target mines, most of the recoverable associated minerals and non-metallic minerals are discharged into tailings. Coupled with the limitations of our country’s geological conditions, there are many symbiotic minerals. In the past for a long time, because there was no multiple metal recovery equipment, only a single metal element could be recovered, and the other elements were mixed into the tailings and abandoned, causing the tailings to take up a lot of land. Cone crushers have a wide range of applications, especially for ultra-fine crushing of hard rocks, ore, slag, refractory materials, etc. Therefore, it has truly made great contributions to the reuse of hard metal tailings.
