Medium and fine crushing is a key link in stone crushing lines, connecting primary crushing and screening. The multi-cylinder cone crusher, following the coarse crushing of a crawler crusher, precisely processes hard rock (≥150 MPa: granite, iron ore) down to 5–30 mm, balancing particle size, energy consumption, and continuous operation—directly influencing the quality of aggregates and raw ore materials. Traditional cone crushers suffer from delays in unloading adjustment, damage from overload, and excessive needle-like particles, whereas the multi-cylinder cone crusher effectively addresses these issues, significantly improving productivity.
Key advantages of the multi-cylinder cone crusher
- Frame made of cast steel ZG310-570 (instead of welded), vacuum degassing and aging, impact strength 40% higher, capable of withstanding impacts up to 300 kN without cracks, machining accuracy 0.1 mm.
- The spindle of the multi-cylinder conical crusher is made of 40CrNiMo alloy (hardness HRC55–60), with a service life exceeding 5 years; four to six hydraulic cylinders (a key feature of the multi-cylinder model) equipped with imported seals, oil leakage ≤0.1 L/1000 h, ensure precise unloading adjustment and sensitive overload protection—these are the main advantages of the multi-cylinder system.
- Wear-resistant segments and bushings: for hard rock — ZGMn13-2 steel (service life 12 months, wear resistance 30% higher); for medium to soft rock — alloy-coated, reducing costs by 20%.
Main use cases
- Ore beneficiation: Standard secondary crushing chamber (15% deeper), 110–220 kW motor, particle throughput >96%, reducing the load on the ball mill and reagent consumption.
- Production of high-quality gravel: Fine crushing chamber, 280–320 vibrations/min, cubic particles ≤5% needle-like, dirt content ≤0.5%, meeting the requirements for infrastructure projects.
- Construction waste processing: Reinforced frame, compatible with crawler mobile stations, production capacity of 200 t/h, gravel recovery rate of 90%, reducing transportation costs by 60%.
Thanks to high-quality manufacturing and intelligent design, this multi-cylinder conical crusher excels in fine crushing of hard rock materials, delivering stable and efficient performance for crushing lines. It enhances the value of finished products, reduces operating costs, and serves as a reliable long-term partner, outperforming traditional models with its multi-cylinder hydraulic system.
