In the production of sand and gravel aggregates, the secondary crushing of soft rock (such as limestone, coal gangue, gypsum, etc.) is a key link to improve the quality of finished products and production efficiency. Although the traditional jaw crusher can complete the coarse crushing, the particle shape of the output material is poor. The PF-1007 small impact crusher has become an ideal choice for secondary crushing of soft rock with its high crushing ratio and excellent particle shape adjustment ability. This article will deeply analyze the core advantages, technical parameters and practical application solutions of PF-1007 in aggregate production lines.
Why Is PF-1007 Suitable For The Secondary Crushing Of Soft Rock?
1. Optimized Design For Soft Rock
Feed particle size ≤300mm, adapted to the needs of secondary crushing after primary crushing. Multi-stage impact plate structure enhances the material impact crushing effect and reduces over-crushing. Wear-resistant alloy plate hammer, prolongs service life and reduces maintenance costs under soft rock conditions.
2. Efficient Production Capacity, Flexible Adaptation To Production Lines
• Processing capacity of 30-70t/h, meeting the needs of small and medium-sized sand and gravel plants.
• Discharge particle size 0-60mm adjustable, can be directly used as concrete aggregate or sand making raw materials.
3. Convenient Maintenance, Reducing Downtime Costs
• The hydraulic cover opening device allows for quick replacement of plate hammer and impact plate, reducing manual disassembly and assembly time.
• Integral cast steel rotor, strong impact resistance, high long-term operation stability.
Technical Parameters And Performance Comparison
| Parameters | PF-1007 | Traditional jaw crusher (comparison) |
| Feed size | ≤300mm | ≤500mm |
| Discharge size | 0-60mm (adjustable) | 50-150mm (non-adjustable) |
| Processing capacity | 30-70t/h | 40-100t/h |
| Motor power | 37-45kW | 55-75kW |
| Particle shape optimization | Polyhedral, less needle-like | More needle-like |
Advantages summary: PF-1007 is significantly superior to traditional equipment in particle shape control, energy consumption, and maintenance convenience, and is especially suitable for aggregate production with high requirements for finished product quality.
Typical Application Of Pf-1007 In The Aggregate Production Line
Case 1: Limestone aggregate processing
Process flow:
Jaw crusher (coarse crushing) → PF-1007 (medium crushing) → vibrating screen (grading) → finished product (5-30mm aggregate).
Effect:
• The finished product has excellent particle shape and improves the compressive strength of concrete.
• The overall energy consumption is reduced by 15%, and the maintenance cost is reduced by 20%.
Case 2: Recycling of construction waste
Applicable materials: concrete blocks, bricks, tiles, etc.
Configuration plan:
Mobile PF-1007 + iron remover + light material separator.
Advantages:
• The output particle size is uniform and can be directly used for roadbed filling.
• The hydraulic cover design facilitates the cleaning of entangled steel bars.
How To Optimize The Operating Efficiency Of PF-1007?
Regularly check the hammer wear: When the wear on one side exceeds 5mm, it needs to be replaced to avoid affecting the crushing efficiency.
Adjust the gap between the impact plates: flexibly control the particle size according to the discharge requirements (such as the gap needs to be reduced for 20mm aggregate).
Suggested supporting equipment:
• Front-mounted GZD960×3800 vibrating feeder to ensure uniform feeding.
• Rear-mounted 3YK1548 vibrating screen to improve classification accuracy.
PF-1007 small impact crusher has become the mainstream choice for secondary crushing of soft rock due to its high-efficiency crushing, low maintenance cost and excellent particle shape. Whether it is a fixed aggregate production line or a construction waste recycling project, PF-1007 can provide a stable and reliable crushing solution.
