Cone crusher is designed and developed based on many advantages of conventional cone crusher, jaw crusher and impact crusher, which is widely used in mining, metallurgy, construction, hydropower, transportation, chemical industry, building materials industry, etc.
Cone crusher has features of a high crushing ratio, compact structure, accurate control system, good finished particle shape, and prolonged working lifetime. It can be widely used in secondary crushing and fine crushing projects to meet different crushing needs for ore and bulk materials in mining, metallurgy, construction, road, railway, water and chemical industries.
Widely used in medium and fine crushing operations in metallurgy, mining, chemical industry, cement, construction, refractory materials and ceramics and other industries.
A cone crusher consists of key parts including the rack, horizontal axis, moving cone, balance wheel, eccentric sleeve, upper broken wall (fixed cone), lower broken wall (moving cone), fluid coupling, lubrication system, hydraulic system, etc. Cone crusher wear parts, the most often replaced parts are the frame liners, mantle liners, bowl liners.
The single-cylinder hydraulic cone crusher is an ideal choice for crushing medium to hard materials, thanks to its efficient performance and smart hydraulic system.
During operation, the motor drives the eccentric bushing to rotate, causing the crushing cone to move in an eccentric motion. Materials are repeatedly compressed and bent between the crushing cone and the bowl liner until they are crushed to the desired size and discharged.
The advanced hydraulic system allows precise adjustment of the discharge opening and provides overload protection, ensuring safe and reliable operation.

Answer: Key factors influencing separation include the table’s motion (stroke and frequency), water volume and slope, feed rate and concentration, and the feed material’s particle size and shape. Proper adjustment of these factors is critical for efficient separation. The table’s longitudinal and transverse slopes must be precisely controlled. The feed concentration should also be appropriate, typically 20-30% for coarse minerals and 15-25% for fine minerals.
Answer: Operation involves observing the bed surface and adjusting the slope, water flow, and feed rate. Regular maintenance includes checking for loose parts, lubricating moving components, inspecting for wear, and cleaning the table surface. Preventative maintenance should be performed regularly, with intervals ranging from every month to once a year.
Answer: Common issues can include table shaking or choppy cuts, uneven material distribution, or poor separation. Troubleshooting may involve checking for loose bolts, damaged springs, or misalignment, adjusting belt tension, inspecting electrical components, and ensuring proper lubrication. If there’s unusual noise, identify the source and eliminate the problem.
Answer:
Advantages: Shaking tables offer high enrichment ratios, are relatively simple to operate, and produce visible separation zones, allowing for easy adjustment and monitoring. They are suitable for a wide range of particle sizes and densities.
Disadvantages: They typically have lower throughput capacity compared to some other methods like jigs or spirals. They also require a relatively large footprint and consume a significant amount of water.
Answer: The selection depends on the material being processed, the desired throughput, and the particle size range. Factors to consider include the deck area, stroke length, and riffle design. Consulting with a manufacturer or expert is recommended to determine the optimal configuration.
