Main Motor Driven Cone Crusher
,V Belt and Drive Gear Hydraulic Cone Crusher
,Effective Crushing of Hard Materials Crushing Machine
Equipped with multiple stroke and cavity combinations, the SH420 model flexibly adapts to medium and fine crushing operations. It is widely applicable in mining, metallurgy, highway construction, chemical industry and building materials, specially suitable for processing high-hardness, high-abrasive ores and various hard rocks.
Driven by the main motor, power is transmitted through the V-belt, transmission shaft and drive gear to rotate the eccentric sleeve. The moving cone generates continuous gyratory swinging motion. Materials are repeatedly squeezed, impacted and crushed between the moving cone and fixed cone. Qualified finished materials are automatically discharged from the bottom discharge opening after reaching the required particle size.
| Cavity Type | Max Feed Size (mm) | Min Discharge Size (mm) | Capacity (t/h) | Max Installed Power (kw) |
|---|---|---|---|---|
| S1 (Extra-Coarse) | 240 | 22 | 85-170 | 90 |
| S2 (Medium-Coarse) | 200 | 19 | 70-130 | 90 |
| H1 (Fine) | 135 | 10 | 45-130 | 90 |
| H2 (Medium-Fine) | 65 | 8 | 35-80 | 90 |
| H3 (Extra-Fine) | 38 | 4 | 27-60 | 90 |
- Wide Application Range: Excellent crushing performance for hard ore, cobblestone, granite and construction waste. Various cavity types fully meet diversified medium and fine crushing demands.
- Low Comprehensive Operating Cost: Supports choke feeding and automatic liner wear compensation, effectively improving crushing efficiency and reducing unit production cost.
- Simple Operation & Easy Maintenance: Integrated hydraulic control realizes one-key intelligent operation. The simplified structure makes daily inspection and wearing part replacement faster and more convenient.
- Positive Pressure Dust-Proof Structure: Adopts advanced positive pressure air sealing technology. Internal cavity pressure is higher than external pressure to completely isolate dust, protect lubricating oil and bearings, and extend equipment service life.
- Optimized Laminated Crushing Cavity: Professional cavity design based on laminated crushing theory ensures higher crushing efficiency, uniform particle shape and longer liner service cycle.
- Aviation-Grade Oil Seal: High-standard hydraulic oil seal ensures stable sealing performance, effectively preventing oil leakage and improving equipment durability.
- Optimized Cast Steel Frame: The overall frame is optimized through mechanical finite element analysis, featuring high strength and strong pressure resistance to adapt to long-term heavy-load crushing work.
- Stable Bevel Gear Transmission: Spiral bevel gear ensures stable operation, low noise, high transmission efficiency and strong bearing capacity.
- Integrated Hydraulic & Lubrication Station: Compact integrated design saves installation space, provides sufficient hydraulic pressure margin and improves overall system stability.
A medium-sized granite quarry enterprise in Brazil, mainly supplying high-quality aggregate for local highway infrastructure projects. The old crushing equipment had serious dust pollution, fast liner wear and poor finished particle shape, restricting production capacity.
The customer adopted SH420 single cylinder hydraulic cone crusher with S2 medium-coarse and H2 medium-fine dual cavity configuration, matched with integrated hydraulic lubrication system and complete wear part accessories.
The overall production capacity increased by 26%; bearing failure rate reduced by 62% due to dust-proof sealing optimization; finished aggregate particle shape was significantly improved to meet highway construction standards; liner service life extended by 33%, and comprehensive operation and maintenance cost reduced by 21%.
