Copper ore crusher is mainly used to crush copper ore. Copper ore is the main raw material for processing refined copper and copper products. copper concentrate. In the crushing process, the three-stage closed-circuit crushing is a modern method suitable for high-hardness copper ore crushing, which can complete the work of ore crushing and partial dissociation, thereby improving the subsequent grinding efficiency; The ore process can make the copper ore grind more fully; in the beneficiation process, the more successful new processes that have appeared in recent years are mainly the mixed flotation process. The main equipment includes: vibrating feeder, jaw crusher, impact crusher, ball mill, flotation machine, dryer.
- Feeding – vibrating feeder
Vibrating feeder is widely used in metallurgy, coal mine, mineral processing, building materials and other industries. The material is pre-screened first.
- Coarse crushing – jaw crusher
The jaw crusher is mainly used for coarse crushing in sand and gravel yard, metallurgy, mining, chemical industry and other industries. The compressive strength can reach 320MPa.
Large pieces of copper ore should be crushed into smaller pieces by jaw crusher first, so as to meet the feeding granularity of medium crushing.
- Secondary crushing – cone crusher
The cone crusher is mainly used for medium and fine crushing of ores with medium and above medium hardness, and can process 12-1000 tons of materials per hour.
The hardness of copper ore is relatively high, which is just suitable for crushing by cone crusher. After processing by cone crusher, finished products of 3-60mm size are produced.
- Screening – Circular Vibrating Screen
The function of the vibrating screen is to screen out the materials that meet the particle size of the next feeding, and at the same time collect the unqualified materials and re-send them to the crushing equipment to be crushed again until the particle size is qualified.
For example, the discharge particle size of the cone crusher is 3-60mm, and in the next grinding process, the feed particle size of the ball mill is required to be below 20-25mm, and the materials with different particle sizes can be separated by a vibrating screen, and the materials below 20mm are fed into In the ball mill, more than 20mm is sent back to the cone crusher for re-crushing.
- Grinding – Ball Mill
The function of the ball mill is to further grind the material into fine particles of 0-200 mesh in order to meet the conditions of the next flotation.
The feeding particle size of the ball mill is 20-25mm or less, and the discharging particle size is 0.074-0.89mm, which can produce 0.65-615 tons of materials per hour. It is very popular in cement, silicate products, new building materials, refractory materials and other industries.
- Grading – Grading Machine
The classifier is a special equipment for particle size classification of ore pulp in the metal beneficiation process. The length of the water tank is 3000-14300mm, and the diameter of the spiral is 300-3000mm. It mainly uses copper ore particles and associated gangue particles. , classify them.
- Ore dressing – mixing barrel and flotation machine
In the flotation process, flotation reagents need to be added to the pulp, so that the useful ore particles can better adhere to the air bubbles generated by the flotation machine, float to the surface of the pulp and then be collected by the flotation machine. The function of the mixing barrel is to stir the pulp, so that the agent and the pulp are mixed evenly, and the reaction time of the agent is accelerated.
- drying – dryer
The copper concentrate collected by flotation has a relatively high water content and cannot meet the standard for use, so it needs to go through the process of dehydration.
The dryer is a drying equipment specially used in mining, beneficiation, chemical and other industries. It can process 1.9-76 tons of materials per hour. In addition to copper concentrate, it can also be used to dry many other metal and non-metallic minerals.
