Huashengming Heavy Industry’s tractor-mounted rock crusher has established a good reputation in the industry thanks to its advanced technology and reliable performance. We have been focusing on mining machinery for 20 years, serving more than 3,000 customers and exporting to 30 countries around the world. Let us show you our high-quality tractor stone crusher.
Double-Roll Crushers
1. Huashengming’s double-roll crusher (especially the hydraulic drive model)
can be integrated into tractor-driven mobile crushing stations, suitable for medium to small-scale stone crushing (such as limestone, quartzite, and other medium-hard rocks). Below is a key compatibility analysis:
Compatibility Dimension Huashengming Double-Roll Crusher Capacity Tractor Application Requirements
Power Matching Supports diesel engine drive (compatible with tractor power systems) Requires direct connection to the tractor’s engine output shaft or hydraulic system
Volume and Mobility Compact double-roll crusher (e.g., 2PGT400 model) with a footprint ≤2㎡ Trailer-mounted design, with an overall length <5 metres
Rock Hardness Limitations Rocks with compressive strength ≤ 160 MPa (e.g., granite is not suitable) Avoid high-hardness, high-abrasive rocks (e.g., basalt)
Production Capacity Requirements Small-sized machine: 5–20 tonnes/hour Suitable for small-scale quarries, farmland road construction, etc.
2. Recommended Tractor-Specific Crushing Solutions
Preferred model:
Huashengming Customised 2PGY500×500 Hydraulic Double Roll Crusher
Core advantages: Hydraulic roll spacing control (real-time adjustment from 1-30 mm) + dual power interface (diesel/electric motor)
Tractor-compatible design: Low chassis frame (ground clearance > 30 cm) + quick-connect coupling
Production Capacity: 12-25 tonnes/hour (compatible with 45-80 horsepower tractors)
Technical Limitations to Note:
Stone Material Specifications: Feed particle size ≤10cm (requires pre-screening or manual sorting)
Maintenance Frequency: When processing stone materials with high soil content, clean accumulated material from the roller gaps every 8 hours
Hydraulic Double Roll Crusher
3. Operational Key Points
Power transmission options:
Option 1: Tractor PTO output shaft → belt pulley → crusher main shaft (low cost, but transmission efficiency approx. 85%)
Option 2: Tractor hydraulic system → crusher hydraulic motor (power loss <5%, recommended option)
Safety precautions:
Install rotating component guards (to prevent flying debris)
Hydraulic lines must use explosion-proof steel braided hoses (pressure ≥ 25 MPa)
4. Procurement Recommendations
Customisation Cost: Huashengming offers a tractor-specific double-roll crusher bare machine (excluding trailer and hydraulic modifications)
Alternative Solution: If budget is limited, the 2PGT400×400 model can be purchased separately and modified with a trailer chassis (saving 30% in costs)
