The JS1400 Standard Spring Cone Crusher, born from 20th-century classic design, features mechanical spring overload protection and gear transmission structure. Specifically designed for secondary crushing of medium-hard materials (such as limestone and basalt), it delivers a maximum processing capacity of 400 t/h.
Small-to-medium quarries: Crushing medium-hard construction aggregates like limestone and dolomite (production line output 200-300 t/h). Cement raw material preparation: Crushing limestone to ≤50mm for vertical mill or ball mill feed. Mine auxiliary crushing: Secondary crushing of low-abrasiveness iron/copper ores. Old plant equipment retrofit: Replacing traditional spring cone crushers (e.g., Simmons 4.25ft) with equivalent specifications.
(1) Spring overload protection: Mechanical springs absorb impact loads, lifting top support sleeves during operation to protect main shaft and gears. (2) Umbrella gear transmission: Heavy-duty spiral umbrella gears transmit power with high load capacity, noise <85dB (at 1-meter distance). (3) Dry oil sealing system: Dust-proof seals and grease isolate contaminants, extending bearing life (>15,000 hours on average). (4) Flank lock nuts: Secured with hydraulic torque wrench to prevent loosening during operation (common failure point in traditional models). (5) Manual discharge port adjustment: Rotate fixed cone support ring to adjust crushing clearance (precision ±2mm, requires shutdown). (6) Symmetrical crushing chamber: 180° symmetrical design allows inverted use after flank wear, increasing utilization rate by 50%.
(1) Cost-effective: Prices are only 60%-70% of HP hydraulic cone crushers of equivalent specifications, ideal for budget-conscious projects.
(2) Easy maintenance: Simple mechanical structure allows independent operation by field workers without requiring specialized hydraulic tools.
(3) Universal spare parts: Components like liners and gears are compatible with Simmons 4.25ft models, ensuring cost-effective procurement.
(4) High reliability: No complex hydraulic/electronic systems, offering strong adaptability to harsh environments (high dust levels, significant temperature variations).
(5) Seamless retrofitting: Compatible with traditional Simmons cone crushers in base dimensions, eliminating the need to rebuild concrete foundations during replacement.
