Difference between PE Series and C Series Jaw Crushers

Design Philosophy and Market Positioning

• Based on traditional jaw crusher design, simple and reliable structure
• Suitable for medium and small-scale mines, building materials, road construction
• High cost-performance ratio, easy maintenance
• Representative models: PE-600×900, PE-750×1060

• Adopting modern optimized design, emphasizing high efficiency, energy saving, and long lifespan
• Designed for large mines and high-capacity production scenarios
• Advanced technology, high automation level, higher price
• Representative models: C80, C100, C120

Structural Design Differences

1. Frame and Bearing Housing

• PE Series: Mostly Adopt welded frame, and the bearing seats are mostly split design

• C Series: The integral cast steel frame has higher compressive strength; the integral bearing seat has a lifespan of up to 50,000 hours

2. Crushing Chamber Shape

• PE Series: Half-V shaped chamber, prone to clogging, lower efficiency
• C Series: V-shaped chamber, actual feed opening matches nominal width, smooth discharge, higher efficiency

3. Adjustment and Lubrication System

• PE Series: Gasket adjustment for discharge opening, requires shutdown; manual lubrication
• C Series: Wedge adjustment for stepless regulation; centralized hydraulic lubrication system, convenient maintenance

Performance and Efficiency Comparison

1. Capacity and Energy Consumption

• C series delivers higher capacity at the same power (e.g., C100 output is about 20% higher than PE-750×1060)
• C series has lower unit energy consumption and better operating costs

2. Reduction Ratio and Suitable Materials

• PE Series: Reduction ratio 4-6, suitable for medium-low hardness materials like limestone
• C Series: Reduction ratio 6-8, suitable for high-hardness materials like granite and basalt

3. Automation Level

• PE Series: Mostly mechanical operation with basic overload protection
• C Series: Equipped with PLC control system, hydraulic protection, remote monitoring, high intelligence level

Application Scenarios

• Projects with limited budget
• Medium and small-scale production (50-500 tons/hour)
• Scenarios with low automation requirements

• Large mines (iron ore, copper ore, etc.)
• High-capacity aggregate production lines
• Projects pursuing long-term operating cost optimization

Economic Analysis

1. Initial Investment

• PE series: Lower price, suitable for budget-limited projects
• C series: 30%-50% higher price than PE series, but with better performance

2. Maintenance Costs

• PE series: Spare parts cheaper but require frequent replacement, higher long-term maintenance costs
• C series: Longer lifespan of wearing parts, longer maintenance intervals, lower long-term operating costs

3. Long-term Benefits

• C series has higher initial investment but is more energy-efficient with longer maintenance cycles, suitable for long-term operation
• PE series is more suitable for short-term projects or budget-limited situations

Selection Recommendations

• Budget is limited
• Production scale is medium-small
• Project duration is short
• Crushing medium-low hardness materials

• High production capacity required
• Working conditions are harsh
• Long-term continuous operation needed
• Emphasis on energy efficiency and automation
• Crushing high-hardness materials

Frequently Asked Questions

• Integral cast steel frame and high-strength materials
• Advanced hydraulic system and intelligent control
• Optimized crushing chamber design and efficient power configuration

• Medium-low hardness materials (limestone): PE series is sufficient
• High-hardness materials (granite): C series is more suitable
• Large-sized materials: C series with deep V-shaped chamber has advantages

• Consider initial investment, capacity improvement, energy savings, and maintenance costs
• C series typically recovers investment within 1-2 years through energy savings and higher output
