Huashengming small crusher deliver efficient performance across multiple industries thanks to their compact design, wear-resistant technology, and adaptability to wet materials.
Small Crusher
1. Recycling of Construction Waste
Application Scenarios
Concrete Block and Brick Crushing: Small double-roll crushers (e.g., 250×400 model) reduce construction waste into 1-3mm recycled aggregate for producing eco-friendly bricks, road base layers, etc., boosting recycling rates by 40%.
On-site Mobile Processing: PTO-driven mobile crushers deploy directly at demolition sites, eliminating transportation costs with hourly output reaching 20 tons (e.g., 2PGT610×400 model).
Technical Advantages
Anti-clogging tooth roll design handles reinforced concrete blocks; hydraulic system automatically retracts upon metal contact for equipment protection.
Enclosed operation + spray dust suppression reduces dust emissions by 60%.
2. Mining & Mineral Processing
Gold Ore Wet Pre-crushing
Silt-bearing gold ore processing: Dual-tooth roller models (e.g., 2PGY800×600) directly crush silt-bearing gold ore with 15% moisture content, producing 2-8mm output for uniform particle size in leaching processes.
Riverbed placer gold operations: Mobile double-roll crushers integrated with gravity separation equipment process riverbank gravel layers on-site without pre-treatment.
Silica Ore and Bauxite Crushing
Silica Ore Fine Crushing: Screenless design of double-stage crushers processes high-silica ore to ≤2mm for refractory materials or high-alumina cement feedstock, reducing energy consumption by 30% compared to traditional ball mills.
Bauxite Primary Crushing: Double-roll crushers replace rod mill + ball mill processes, producing 3-5mm output and boosting system capacity by 20%-30%.
3. Coal and Solid Waste Processing
Wet Coal and Coal Gangue Crushing
Coal Slurry Processing in Washing Plants: Dual-stage crushers (e.g., 800×600 model) utilize a “dual-rotor screenless” structure to crush water-bearing coal slurry to ≤3mm fine sand with near-zero clogging rates, enabling operation even during rainy weather.
Briquette Raw Material Preparation: 35-55 tons per hour output with uniform particle size, enhancing briquette forming quality.
Industrial Solid Waste Resource Recovery
Steel Slag/Furnace Slag Crushing: Box-type hammer crushers process metal waste, separating rebar from concrete to produce 5-10mm aggregate for metallurgical reuse.
Coal Gangue Brick Manufacturing: Dual-stage crushers pulverize coal gangue below 2mm, enhancing environmental brick density and permeability.
4. Sand Aggregate & Hard Rock Sand Production
High-Quality Manufactured Sand Production
Basalt/Granite Sand Making: Hydraulic double-roll crushers (e.g., 2PGY1500×1000) produce premium sand ≤3mm in a single pass. Features well-rounded particle shape and low over-crushing rate, replacing traditional three-stage crushing processes.
River Pebble Fine Crushing: Dual-tooth roller crushers process high-moisture river pebbles with ±0.1mm hydraulic gap precision, meeting concrete aggregate standards.
Small-Scale Sand & Gravel Plant Applications
Low-Cost Start-Up: 250×400 double-roll crusher (from ¥13,500) delivers 2-10 tons/hour, ideal for pilot mining at dispersed sites.
Mobile Production Line: PTO-driven models suit gridless mountainous areas with rapid relocation capabilities.
5. Innovative Applications in Special Scenarios
Underground Coal Mine Safety Crushing
Hydraulic breaker for underground operations: The MWD2/0.12L hydraulic breaker crushes large gangue blocks in coal mining faces. Its electric-hydraulic system eliminates exhaust pollution, and its compact size avoids collisions with supports. Replacing manual pneumatic hammers, it boosts efficiency by 50%.
Eco-Brick and Permeable Material Production
Tailings/Slag Recycling: Dual-stage crushers process tailings/slag to ≤3mm for permeable brick production, achieving 20%-30% permeability (e.g., Kunming construction waste recycling project).
