Huashengming Lump Crusher centers on three core series—twin-tooth roller, counter-roller, and box-type heavy hammer—delivering efficient crushing solutions for lump materials (such as ore, coal, construction waste) with varying hardness, moisture content, and particle size requirements. Below is a detailed analysis of its core technologies, product series, and application scenarios:
Lump Crusher
1. Core Product Series and Technical Features
Twin-Tooth Roller Crusher
Working Principle: Applies squeezing + shearing forces to materials via two counter-rotating toothed rollers, achieving flexible crushing that reduces over-crushing and increases block retention rate by over 30%.
Particle Size Control: Adjustable roller gap (1-50mm) enables precise output size control (e.g., coal crushing to 20-40mm), meeting diverse industry requirements.
Wear-Resistant Design: Roll teeth feature a high-chromium alloy + rare metal composite material (triple-layer composite structure), delivering over twice the service life of conventional equipment (handling capacity exceeding 30,000 tons).
Applications: High-moisture, sticky materials like coal, coke, limestone, and clay-bearing gold ore (moisture content ≤15%).
Hydraulic/Spring Adjustment: Supports stepless roll gap adjustment (±0.1mm precision), output particle size range 1-40mm, over-crushing rate below 10%.
Power Adaptability: Supports electric, diesel dual power, or PTO drive (connects to tractors), suitable for off-grid mining areas.
Model Coverage:
Small Unit (250×400): 2-10 tons/hour
Large Unit (1500×1000): 150-400 tons/hour, with AI dynamic control.
Box-Type Heavy Hammer Crusher
Large Block Processing: Directly crushes 600mm feed to below 25mm, completing coarse and medium crushing in one pass with a crushing ratio of 1:24.
Innovative hammer design: High-chromium alloy composite hammers (front end with high hardness + handle with high toughness) rotate 360° for repeated use, extending service life by 60%.
Suitable materials: Hard rock with compressive strength ≤150MPa, such as granite and basalt.
Screenless Double-stage Crusher
Dual rotor linkage: Upper and lower rotors perform relay crushing, eliminating screen plate design and completely resolving wet/sticky material blockage (blockage rate approaches 0%).
Construction waste recycling: Crushes concrete blocks into 1-3mm recycled aggregate, boosting recycling rate by 40%.
2. Performance Advantages & Innovative Technologies
Wear-Resistant & Long-Life
Roll shells/hammer heads utilize high-chromium manganese steel + rare metal composite materials (patented technology), with surface hardness HRC60+, reducing annual replacement frequency by 60%.
Energy Efficiency & Environmental Protection
Unit energy consumption 15%-20% lower than traditional hammer crushers, dust emissions reduced by 60%, noise ≤75 dB (enclosed design + noise reduction technology).
Intelligent Control
Hydraulic models feature AI-driven dynamic roll gap adjustment, remote start/stop, and predictive fault alerts (e.g., 72-hour advance warning for bearing wear).
Anti-Blocking Design
Dual-tooth roll spiral discs enhance wet material engagement force. Two-stage crushers employ screenless bottom structures, enabling direct crushing of materials with up to 15% moisture content.
