Huashengming High-Quality Crusher: We have specialised in mining machinery for 20 years, served over 3,000 customers, and exported to 30 countries worldwide. Let us show you the high-quality crushers we produce.
1. Core Technical Advantages
Double roller crusher
Hydraulic Precision Control
The discharge particle size is adjustable from 1 to 5 mm. The roller gap is adjusted in real time via the hydraulic system to ensure uniform particle size of the finished sand and a over-crushing rate below industry standards.
Equipped with an overload protection device, it automatically retreats upon encountering foreign objects like iron blocks, preventing equipment damage.
Wear-Resistant and Durable Design
High-chromium manganese steel roll liners with a hardness of over 8 on the Mohs scale, offering a lifespan of up to 2-3 years (counterfeit products last only 3-6 months).
The roller body is thickened to 20 cm, and large models (such as the 2PGY2000×1000) can operate continuously for 18 months without faults.
Highly adaptable to complex operating conditions
Screenless design: effectively processes high-moisture materials (such as coal slurry, construction waste) without blockages, with a 40% increase in wet material throughput.
Dual motor drive: energy consumption is 30% lower than traditional equipment, with large models producing 400 tonnes per hour reducing electricity costs by 1.5 kWh per tonne.
2. Product Series and Performance Parameters
Model Classification Representative Model Capacity (t/h) Feed Size (mm) Application Scenarios Reference Price
Small Spring Type 2PGT400×250 2-10 ≤25 Small and medium-sized sand plants, laboratories Starting from ¥18,000
Medium Hydraulic Type 2PGY1000×1000 80-100 ≤40 River pebble sand making, quartz stone fine crushing ¥200,000+
Large CNC model 2PGY2000×1200 300-400 ≤120 Large-scale sand and gravel aggregate production lines Negotiable (tens of thousands of yuan)
Note:
Mobile models (integrated tyre chassis) are priced 30%-50% higher and support relocation within 1 hour.
Custom models can be equipped with discharge scrapers to address wet material sticking to the rollers.
3. Application Scenarios and Customer Cases
Construction Waste Recycling:
Dual-rotor series technology (Patent No. ZL202310001234.5), achieving a single-stage crushing size of ≤3mm. A customer in Henan reported, ‘No more midnight blockage clearance.’
River Pebble Sand Making:
The 2PGY1000×1000 model produces finished sand with 85% particle size ≤3mm, increasing sand prices by 20% (compared to traditional equipment).
Mining Fine Crushing:
A western mining company adopted the HSM-800 model, saving over ¥100,000 in annual electricity costs and increasing production capacity by 30%.
4. Trial Operation Commitment:
Free testing with materials provided; compensation for transportation costs if production capacity targets are not met.
5. After-sales service support:
Response time: Solutions provided within 8 hours, engineers on-site within 48 hours.
Lifetime maintenance: Core components (bearings, hydraulic systems) covered by a 3-year warranty, with lifetime supply of spare parts at cost price.
Customised services: Production line solutions designed based on material Mohs hardness and daily output (e.g., granite requires a jaw crusher + double-roll crusher).
