In South Africa's sand and gravel aggregate production sector, a 40-50 tons/hour (tph) crushing line is an ideal choice for small and medium-sized sand and gravel facilities. This line offers a moderate investment, a small footprint, and low operating costs, making it particularly well-suited for regional sand and gravel supply needs. This article will comprehensively analyze the key equipment selection considerations for a 40-50 tph crushing line, helping you build an efficient and cost-effective crushing system.
1. Core Equipment Selection for a 40-50 tph Crushing Line
1.1 Primary Crushing Equipment - Jaw Crusher
Recommended Models:
• PE400×600 (16-64 tph)
• PE500×750 (40-110 tph)
Technical Parameters:
• Feed Inlet Dimensions: 400×600mm or 500×750mm
• Maximum Feed Size: ≤340mm
• Discharge Adjustment Range: 40-100mm
• Motor Power: 30-55kW
• Equipment Weight: 6.5-12.5 tons
Selection Recommendations:
For a 40-50 tph production capacity, the PE500×750 is a more reliable choice, providing a more stable feed for subsequent processes. For budget constraints and more fragile materials, the PE400×600 is an option.
2.2 Secondary Crushing Equipment Selection
Depending on the material hardness, there are two main configuration options:
Option A: Medium-hard materials (limestone, dolomite, etc.)
Recommended equipment: Impact crusher
Recommended models:
• PF1010 (processing capacity 50-80 tph)
• PF1210 (processing capacity 70-130 tph)
Technical advantages:
• High crushing ratio (up to 20:1)
• Good particle shape, low flake content
• Easy maintenance, easy replacement of wearing parts
Option B: High-hardness materials (granite, basalt, etc.)
Recommended equipment: Cone crusher
Recommended models:
• PYB1200 (standard type, processing capacity 40-110 tph)
• PYD1200 (short head type, processing capacity 30-90 tph)
Technical advantages:
• Long wear-resistant parts life, low operating costs
• High crushing force, suitable for high-hardness materials
• Uniform product particle size
3. Screening Equipment Selection
Recommended models:
• 3YK1548 (three-deck screen, processing capacity 50-200 tph)
• 2YK1860 (two-deck screen, processing capacity 80-300 tph)
Configuration Key Points:
• Number of screen layers: 2-3 layers recommended
• Mesh size: Configure according to final product specifications (e.g., 0-5mm, 5-10mm, 10-20mm, etc.)
• Mounting angle: 15-20° is preferred
2. Auxiliary Equipment Configuration Plan
2.1 Feeding Equipment
• Vibrating Feeder: ZSW380×96
• Processing capacity: 80-150 tph
• Motor power: 7.5 kW
• Trough dimensions: 3800×960 mm
2.2 Conveying Equipment
• Belt conveyor: B650-B800
• Bandwidth: 650-800mm
• Belt Speed: 1.0-1.6m/s
Conveying Capacity: 100-200tph
2.3 Dust Removal System
• Pulse Bag Dust Collector:
• Air Volume: 6,000-10,000m³/h
• Filtration Area: 120-180㎡
• Dust Removal Efficiency: ≥99.5%
3. Production Line Layout Recommendations
Site Planning Key Points
• Equipment Spacing: Maintain 1.5-2m of maintenance clearance
• Conveyor Angle: ≤18° is recommended
• Stockpile Height: ≤5m to prevent material segregation
4. FAQs
Q1: What site size is required for a 40-50tph production line?
A: We recommend reserving a 30m x 40m (approximately 1,200㎡) site, including a raw material and finished product storage area.
Q2: How long does it take to build a production line?
A: From equipment procurement to commissioning, it typically takes 2-3 months.
Q3: How can I improve the actual output of my production line?
• Maintain uniform feed
• Regularly check the condition of the screen
• Promptly replace worn crushing chamber liners
• Optimize screening efficiency
