How to achieve laminated crushing of cone crusher

Cone crusher is a kind of crushing equipment widely used in mining, construction, chemical industry and other industries. Its main function is to perform medium and fine crushing of ores and rocks of various hardness. Laminated crushing is a working mode of cone crusher, which crushes the material in the crushing chamber by applying pressure. How to achieve laminated crushing of cone crusher?
 

1. Principle of laminated crushing of cone crusher

Laminated crushing refers to the extrusion crushing of materials in the crushing chamber with multiple layers. During the crushing process, the materials will not only be subjected to the extrusion force of the moving cone and the fixed cone, but also extrusion collision will occur between the materials. This crushing method truly reflects the laminated characteristics of the materials in the crushing process, thereby improving the crushing effect.

2. Prerequisites for laminated crushing

1. Sufficient feeding

Sufficient feeding is the basis for laminated crushing. Laminated crushing effect can only be formed when the crushing chamber is filled with a sufficient number of material layers. Experiments show that when the number of crushing layers is 6-10 layers, the energy saving effect and output characteristics are obvious. Therefore, in actual operation, continuous and stable feeding should be ensured to avoid low crushing efficiency caused by insufficient feeding.

2. Uniform feeding

Uniform feeding is the key to ensure the smooth operation of the crusher. Uniform feeding can make the force distribution of the material in the crushing chamber reasonable, avoiding the increased vibration and wear of the equipment caused by uneven material distribution. In order to achieve uniform feeding, devices such as vibrating feeders or buffer silos can be set in the feeding system to adjust and control the feeding speed and feeding amount.

3. Uniform particle size

Uniform feeding particle size is also an important condition for achieving laminated crushing. When the geometric dimensions of the material particle size vary greatly, the small material will protect the large material from being crushed, that is, the fine particle protection phenomenon. In order to avoid this phenomenon, the feeding particle size should be ensured to be uniform, and the raw materials can be pre-treated by screening equipment to remove oversized or undersized particles.

III. Optimization measures

1. Equipment selection and configuration

Choosing a suitable cone crusher is a prerequisite for achieving laminated crushing. Cone crushers of different models differ in crushing capacity, material utilization and product structure. Therefore, production requirements, material characteristics and economic benefits should be fully considered when selecting equipment. At the same time, the reasonable configuration of other equipment such as feeders, screeners and conveyors in the crushing production line is also an important measure to improve crushing efficiency and product quality.

2. Regular maintenance and care

Regular maintenance and care are the key to ensure the long-term stable operation of the cone crusher. The equipment should be inspected and repaired regularly, and the parts with severe wear and wearing parts should be replaced in time; at the same time, the management of the lubrication system should be strengthened to ensure that all parts of the equipment are well lubricated to reduce wear and failure. In addition, attention should be paid to the cleaning and anti-corrosion of the equipment to extend the service life of the equipment.

3. Training and management of operators

The skill level and sense of responsibility of the operator directly affect the operating efficiency and product quality of the cone crusher. Therefore, the training and management of operators should be strengthened. Improve the skill level and safety awareness of operators through regular training and assessment; at the same time, establish sound operating procedures and management.
