Cone crusher is a kind of crushing equipment widely used in mining, construction, chemical industry, etc. Its main function is to break and fine break ores and rocks of various hardness. Laminated crushing is a mode of operation of the cone crusher, which causes the material to be crushed in the crushing chamber by applying pressure. The following is a brief introduction article on how to achieve lamination crushing in cone crusher.
First, cone crusher laminated crushing principle
Laminated crushing refers to the extrusion crushing in which the material is distributed in multiple layers in the crushing chamber. During the crushing process, the material will not only be subjected to the extrusion pressure of the moving cone and the fixed cone, but also the extrusion collision between the materials. This crushing method truly reflects the lamination characteristics of the material in the crushing process, thus improving the crushing effect.
Second, the prerequisite for the realization of laminated crushing
1. Feed well
Adequate feeding is the basis of laminating crushing. Only when the crushing chamber is filled with a sufficient number of material layers can an effective lamination crushing effect be formed. The experiment shows that when the number of broken layers is 6-10 layers, the energy saving effect and yield advantage are most obvious. Therefore, in actual operation, it should be ensured that the feeding is continuous and stable to avoid the low crushing efficiency caused by insufficient feeding.
2. Feed evenly
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 and avoid the vibration and wear of the equipment caused by the uneven distribution of the material. In order to achieve uniform feeding, devices such as vibrating feeders or buffer silos can be set up in the feeding system to adjust and control the feeding speed and feed amount.
3. Uniform particle size
Uniform feed size is also an important condition for laminating crushing. When the geometric size of the material particle size is very different, the small material will protect the large material from being broken, that is, the fine particle protection phenomenon. In order to avoid this phenomenon, it should be ensured that the feed size is uniform, and the raw material can be pre-treated by the screening equipment to remove too large or too small particles.
Third, optimization measures
1. Equipment selection and configuration
Choosing the right cone crusher is the premise of laminating crushing. Different types of cone crusher have differences in crushing capacity, material utilization rate and product structure. Therefore, factors such as production requirements, material characteristics and economic benefits should be fully considered in the selection of equipment. At the same time, the reasonable configuration of other equipment in the crushing production line, such as feeders, screeners and conveyors, is also an important measure to improve the crushing efficiency and product quality.
2.Regular maintenance and maintenance
Regular maintenance and maintenance is the key to ensure the long-term stable operation of the cone crusher. Regular inspection and maintenance of the equipment should be carried out, and timely replacement of severely worn parts and wearing parts; At the same time, strengthen the management of the lubrication system to ensure that all parts of the equipment are well lubricated to reduce wear and failure. In addition, attention should also be paid to the cleaning and anti-corrosion work of the equipment to extend the service life of the equipment.
3. Training and management of operators
The skill level and 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
