A New Standard for Efficient Crushing of High-Hardness Ore

Double Chamber Hard Rock Crusher Equipment Overview

The DLKPC series double-chamber hard rock crusher is specifically designed for high-hardness ores such as fluorite, basalt, and river pebbles. Its symmetrical double-chamber structure increases capacity by 30%, while the hydraulic shell opening system improves maintenance efficiency by 60%. Equipped with two (200kW × 4) motors, it handles feed sizes up to 180 mm and achieves a production capacity of 250–350 t/h (DLKPC1313). The unit is currently operating reliably on a 700 t/h fluorite processing line in Jiujiang, Jiangxi.

Double Chamber Hard Rock Crusher Equipment Highlights

30% Increased Capacity with Dual Chambers: The symmetrical dual-chamber design delivers significantly higher throughput than single-chamber models, efficiently supporting a 700 t/h ore processing line.

Hydraulic Shell Opening Increases Efficiency by 60%: Left and right shell opening directly exposes the rotor hammers, halving maintenance labor and reducing downtime for repairs by 40%.

Reinforced Liners Reduce Costs by 30%: Thicker impact liners + secure positioning blocks + bolt counter-tension to prevent shearing; high-wear-resistant consumables reduce costs by 30%.

High Utilization of Double-Sided Hammers: Hammers can be flipped for use; flip before replacement, making one set last as long as two.

Hydraulic Gap Control Boosts Efficiency by 70%: Remotely adjust the gap between hammers and liners, speeding up gap adjustment by 70% and ensuring precise and stable discharge particle size.

Flexible Configuration Across the Full Series: Models range from DLKPC1210 to DLKPC1316, with feed openings from 600×1040 mm to 600×1700 mm and power ratings of (110–250)×2 kW for flexible matching.

Double Chamber Hard Rock Crusher Application Scenarios

High-Hardness Ore Processing: Medium and fine crushing of fluorite, basalt, and other materials, with a 25% increase in crushing efficiency compared to standard impact crushers.

Mining, Metallurgy, and Mineral Processing: Primary crushing for iron, copper, and gold ores, suitable for high-capacity production lines.

Cement Raw Material Preparation: Continuous and stable feeding; dual-chamber design ensures high output.

Coal Gangue and Industrial Waste: Validated in a 500 t/h project in Hengyang, Hunan; suitable for environments requiring frequent maintenance.

Double Chamber Hard Rock Crusher Customized Process Flow

① Jaw crusher for primary crushing

② Dual-chamber high-efficiency fine crushing (symmetrical dual-chamber synchronous operation + hydraulic gap control)

③ Vibrating screen (oversize material recirculated in closed-circuit)

④ Baghouse dust collector

⑤ Intelligent monitoring

After being coarsely crushed by a jaw crusher to ≤180 mm, the ore enters the dual-chamber crusher. The dual chambers operate synchronously, and real-time hydraulic gap control ensures consistent particle size. During maintenance, a single button opens the housing to expose the rotors, reducing maintenance time from several hours to less than one hour and cutting overall line downtime by 40%.
