Precision crushing and efficient screening are crucial links in the ore dressing process, which directly affect the ore processing capacity and dressing efficiency.
Precision crushing refers to the use of appropriate crushing equipment and processes to crush large pieces of ore into a particle size that meets the requirements of subsequent processing while maintaining a low over-crushing rate and high crushing efficiency. The realization of precision crushing depends on the following aspects:
Select appropriate crushing equipment:
Jaw crusher: Suitable for the coarse crushing stage, large pieces of ore are crushed into smaller particles through the extrusion of two jaw plates.
Cone crusher: Suitable for the medium and fine crushing stages, using the gradually decreasing gap between the conical crushing head and the wall of the crushing chamber to squeeze and crush the ore.
Hydraulic roller crusher: The hydraulic control system automatically adjusts the spacing and crushing force between the rollers to achieve precise crushing, especially suitable for occasions that require fine crushing.
Optimize the crushing process:
The crushing process is divided into three stages: coarse crushing, medium crushing and fine crushing. Use suitable crushing equipment in each stage to ensure crushing efficiency and particle size control.
Adjust crushing parameters, such as crusher speed, feed rate, etc., according to the properties of the ore (such as hardness, toughness, etc.) to achieve the best crushing effect.
Regular maintenance and care:
Regularly check and maintain the crushing equipment to ensure that the equipment is in good operating condition and reduce downtime.
Replace severely worn parts, such as jaw plates, crushing heads, etc., to maintain the crushing performance of the equipment.
Efficient screening
Efficient screening means that the crushed ore is graded according to particle size through appropriate screening equipment and processes to meet the requirements of subsequent mineral processing processes. The realization of efficient screening depends on the following aspects:
Choose the right screening equipment:
Vibrating screen: suitable for ore with smaller particle size, and the ore is graded by vibration. Vibrating screens are divided into circular vibrating screens, linear vibrating screens, and other types, which can be selected according to specific needs.
Drum screen: suitable for ore with larger particle size, and the ore is graded by rotation. Drum screen has the advantages of simple structure and large processing capacity.
Optimize screening process:
Reasonably configure the number and specifications of screening equipment to ensure that screening efficiency and processing capacity match.
With a multi-layer screen structure, multiple particle sizes of ore can be obtained in one screening, which improves the screening efficiency.
Adjust the aperture and inclination of the screen according to the particle size distribution characteristics of the ore to achieve the best screening effect.
Regular maintenance and care:
Regularly check and maintain the screening equipment to ensure the integrity of the screen and the normal operation of the vibrator.
Clean the blockage on the screen to keep the screen holes unobstructed.
Precise crushing and efficient screening are important and indispensable links in the ore beneficiation process. By selecting appropriate crushing and screening equipment, optimizing process parameters, and regularly maintaining and servicing equipment, the ore processing capacity and beneficiation efficiency can be significantly improved, providing strong guarantees for the production of mining enterprises.
