Developed based on global advanced cone crushing technology and combined with the latest industrial R&D achievements, the SH430 single cylinder hydraulic cone crusher is a large-capacity intelligent crushing equipment optimized for heavy-duty hard rock working conditions. It adopts a highly integrated bottom single-cylinder hydraulic structure, which integrates gap adjustment, over-iron protection and automatic cavity cleaning functions in one compact body. It abandons cumbersome external mechanical structures, making the whole machine simpler, more robust and more convenient to operate.

With multiple heavy-duty stroke and large crushing cavity options, the SH430 model is specially designed for coarse and medium crushing of high-hard materials. It is widely used in large mines, stone quarries, road engineering, chemical industry and building material industries, capable of stably processing high-hardness and high-abrasive ores and rocks.

The motor drives the eccentric sleeve to rotate through the V-belt drive system and transmission gear set. The moving cone produces periodic gyratory motion under eccentric force. Materials are continuously impacted, squeezed and crushed between the moving cone and fixed cone layer by layer. The materials that meet the discharge particle size are automatically discharged from the bottom outlet to complete the continuous crushing process.

• Diversified Working Condition Adaptation: Suitable for high-hard rock, mine ore, pebble and construction recycled materials. Multiple large cavities freely switchable to meet large-scale coarse and medium crushing production needs.
• Economic Operation & Low Consumption: Adopts scientific choke feeding mode and automatic liner wear compensation system, maximizing crushing efficiency and effectively reducing unit material production cost.
• Intelligent Control & Low Maintenance: Hydraulic one-key control realizes automatic adjustment and cavity cleaning. The simplified mechanical structure reduces daily maintenance difficulty and labor cost.
• Reliable Positive Pressure Sealing System: Unique positive pressure dust isolation design prevents external dust from entering the lubrication system, protects bearings and gear components, and ensures long-term stable operation of the equipment.
• High-Efficiency Laminated Crushing Cavity: Optimized cavity curve design realizes layered crushing, making finished aggregate particle size uniform, improving product quality and extending wear part service life.
• High-End Aviation-Grade Oil Seal: The hydraulic cylinder is equipped with aviation-grade sealing parts to avoid oil leakage, ensuring long-term stable hydraulic system operation.
• Reinforced Cast Steel Main Frame: Through finite element stress analysis, the overall thickened cast steel frame has super strong impact resistance and can adapt to 24-hour continuous heavy-duty production.
• Efficient & Silent Transmission System: High-precision spiral bevel gear has large bearing capacity, stable transmission, low noise and high working efficiency.
• Integrated Hydraulic Lubrication Design: The hydraulic station and lubrication station are integrated into one unit, saving installation space, improving system coordination and enhancing overall operational reliability.

Customer Background: A large mining EPC contractor based in South Africa, specializing in the processing of high-hard gold-bearing ores. The company’s old crushing units suffered from limited throughput and cumbersome mode switching between coarse and medium crushing, which severely restricted overall production efficiency and project progress.

Adopted Solution: The client introduced the SH430 single cylinder hydraulic cone crusher, equipped with switchable S1 extra-coarse and S3 coarse crushing cavities, paired with a full set of integrated hydraulic and lubrication systems to match its large-scale mineral processing line.

Project Effect: The overall ore handling capacity increased by 31%. The dual-cavity design enables one machine to handle both coarse and medium crushing tasks, eliminating extra equipment investment. The optimized transmission and sealing structure reduced equipment failure rate by 54%, completely solving hydraulic oil leakage issues. The reinforced cast steel frame perfectly adapts to 24-hour uninterrupted heavy-load mining production.
