High Crushing Ratio Cone Crusher Machine For Mining Quarry Construction Materials

SHQ series full hydraulic cone crusher is optimized and upgraded on the basis of traditional cone crushing equipment, abandoning complex redundant structural design. It has the characteristics of simple overall structure, flexible operation, convenient maintenance and low comprehensive manufacturing and operating cost. The whole machine adopts modular assembly design, and all wearing parts and core components can be disassembled, inspected and maintained from the top or side of the equipment, greatly saving maintenance time and labor cost.
Equipped with an independent circulating thin oil lubrication system and high-performance non-contact labyrinth sealing components, the equipment achieves zero-wear sealing operation, effectively blocking dust invasion and greatly extending the service life of bearings and core transmission parts. The product covers four models: SHQ300 (910mm movable cone), SHQ400 (1200mm), SHQ500 (1395mm) and SHQ600 (1650mm). With motor power ranging from 75kw to 250kw and production capacity covering 48–640 t/h, it is the most cost-effective durable crushing equipment for medium and large mines, cement plants and aggregate factories.

The equipment adopts a simplified and reliable transmission structure. The motor transmits power through the horizontal shaft and gear set to drive the eccentric sleeve to rotate, and the movable cone swings periodically to realize material extrusion and crushing. The independent thin oil lubrication station provides continuous circulating cooling and lubrication for bearings, eccentric sleeves and other high-speed operating parts, avoiding high-temperature wear and dry friction damage.
The optimized labyrinth sealing structure completely isolates internal moving parts from external dust and impurities, ensuring clean operation inside the equipment. The full hydraulic protection system undertakes overload protection and cavity clearing work, reducing equipment failure caused by human operation and material impurities, and further reducing daily maintenance workload.

• 1. Simple Structure & Convenient Maintenance The overall structure is simple and reasonable with few failure points. All core parts and wearing parts can be disassembled and maintained from the top or side, realizing rapid maintenance without large-scale disassembly, saving time and labor.
• 2. Independent Thin Oil Lubrication, Ultra-long Service Life The special circulating thin oil lubrication system realizes full cooling and lubrication of core components. Matching with non-contact dust-proof sealing design, it effectively prevents dust from entering, avoids component wear, and greatly prolongs equipment service life.
• 3. Low Comprehensive Operating Cost Low failure rate, simple maintenance and long service life of wearing parts effectively reduce long-term operation and maintenance investment, with high cost performance for long-term continuous production.
• 4. Stable Full-shift Operation The optimized structural rigidity and lubrication system support 24-hour continuous heavy-duty operation, suitable for large-scale non-stop production lines.

Long-term continuous crushing operations in mines and quarries, cement plant raw material processing, construction waste recycling, refractory material crushing, and various medium and high-hardness rock crushing projects requiring low maintenance cost.
