3" x 4" Laboratory Jaw Crusher - 220V, Single-Phase, 50/60Hz

The Laboratory Jaw Crusher is a high-capacity sample-preparation crusher designed to reduce aggregates, rock, and ore before laboratory testing or secondary crushing. Its 3" x 4" jaw accepts material up to approximately 3" and delivers throughput up to 500 lb per hour, making it an excellent choice for laboratories that need considerably more capacity than smaller benchtop jaw crushers.

Key Features

• Accepts aggregate and rock feed up to approximately 3"
• Up to 500lb / 226.8 kg per hour throughput
• Adjustable jaw opening from 0.375" to 1.5"
• Produces material with approximately 50% passing 1/4" / 6.3 mm
• Variable-speed operation up to 375 rpm
• High-manganese steel jaw plates can be rotated as they wear
• Welded-steel base frame
• 220V, 50/60Hz, 15A electrical requirements
• Power cord and plug included

Typical Applications

Aggregate sample preparation, rock crushing, mineral processing, geotechnical laboratories, DOT laboratories, universities, and commercial construction materials testing laboratories.

Lab Manager's Tip

Choose this crusher when sample volume is too high for the smaller 2.25" x 3" laboratory crusher. Product volume increased to as much as 500lb/hr. and accepts larger feed, which can significantly reduce preparation time for bulk aggregate samples.
