As the core equipment in the field of medium and fine crushing, cone crusher has become the key equipment in the fields of metal mines, building materials, etc. with its advantages of lamination crushing principle, high processing capacity and low energy consumption. It is applicable to a wide range of materials, mainly covering the following types:

1. Metal ore

‌High hardness metal ore‌: Metal ores such as gold ore, iron ore, and copper ore have high hardness (Praeter hardness coefficient f≥8), so they need to be processed by cone crusher with lamination crushing principle. The extrusion crushing space is formed between the moving cone and the fixed cone, which can realize continuous compression crushing of materials, and the crushing ratio is as high as 1:8-1:10‌.

‌Medium hardness ore‌: Medium hardness ores such as lead-zinc ore and molybdenum ore can achieve particle size control by adjusting the size of the closed side discharge port (5-60mm) to meet the needs of the ore dressing plant for fine crushing products‌.

2. High-hardness rocks and building materials

Igneous rocks: granite, basalt, diabase and other rocks have a hardness of 6-7 on the Mohs scale. The cone crusher can effectively reduce the wear rate through the hydraulic protection system and wear-resistant high-manganese steel liner design, and the processing capacity of a single machine can reach 50-2000t/h.

Building aggregate raw materials: When natural stones such as pebbles and quartz are processed by cone crushers, the finished product has excellent particle shape (needle-shaped content <7%), which meets the requirements of aggregate grading for highway and railway construction.

3. Other applicable materialsIndustrial waste slag

Industrial solid wastes such as steel slag and copper slag can be recycled through cone crushers. Its hydraulic cavity clearing function can prevent material blockage and ensure continuous production.

Artificial sand making raw materials: In the machine-made sand production line, the cone crusher is used in conjunction with the impact sand making machine to crush materials such as limestone into 0-5mm fine sand, and the fineness modulus can be controlled between 2.4-3.0.

4. Technical advantages and adaptation conditions

‌ Crushing principle optimization: Based on the layered crushing theory, the material undergoes multiple extrusion and shearing in the crushing chamber, the product particle size is uniform, and the energy consumption is reduced by 30% compared with the traditional crusher.

‌ Intelligent control: Equipped with hydraulic adjustment of the discharge port, iron protection device and thin oil lubrication system, it can monitor the main shaft position, lubricating oil temperature and other parameters in real time, and the equipment operation rate is increased to more than 95%.

‌ Wear-resistant design: The core components such as the crushing wall and mortar wall cast by alloy steel have a service life of 8000-12000 hours.

The wide application of cone crushers in mining, building materials, metallurgy and other fields is inseparable from their strong adaptability to material hardness and particle shape. In the future, with the continuous upgrading of intelligent control technology and wear-resistant materials, its crushing efficiency and economy will be further improved.
