Jaw crushers are sized based on the feed opening width and length, which determines the maximum feed size they can accept and their crushing capacity. Here are the common size classifications for jaw crushers:

1. Small Jaw Crushers (Laboratory/Pilot Scale)
– Feed Opening: 4″ x 6″ (100 x 150 mm) to 12″ x 24″ (300 x 600 mm)
– Capacity: Up to 50 TPH (Tons Per Hour)
– Applicati
: Lab testing, small-scale mining, sampling
2. Medium Jaw Crushers (Standard Production)
– Feed Opening: 16″ x 24″ (400 x 600 mm) to 24″ x 36″ (600 x 900 mm)
– Capacity: 50–300 TPH
– Applications: Aggregate production, medium-sized mining operations
3. Large Jaw Crushers (Heavy-Duty/Quarry Use)
– Feed Opening: 30″ x 42″ (750 x 1065 mm) up to 60″ x 80″ (1500 x 2000 mm)
– Capacity: Over 500 TPH
– Applications: Large-scale mining, quarrying, high-capacity crushing
Key Factors Influencing Jaw Crusher Size Selection:
1. Feed Material Size – Must be smaller than the crusher’s gape.
2. Required Output Size – Determined by the closed-side setting (CSS).
3. Production Capacity Needs – Higher tonnage requires larger crushers.
4. Power & Drive System – Bigger crushers need stronger motors.
