4″ × 5″ Laboratory Jaw Crusher

Complete with door, feed hopper, collecting drawer & base frame

A laboratory jaw crusher designed for rapid reduction of hard, brittle, and tough materials.
Built with a single-toggle mechanism consisting of one fixed and one moving jaw plate.
Suitable for both batch and continuous crushing operations.
Ideal for laboratory use, small-scale operations, and field applications such as prospecting.
Designed for durability, long service life, and easy maintenance, even in remote areas.
Floor-mounted unit with motor positioned at the rear of the main structure.

Working Principle

• Material enters the crushing chamber through a guide chute.
• Crushing occurs between a fixed jaw plate and a moving jaw plate.
• The material is progressively reduced until it passes through the set gap.
• The gap can be adjusted precisely using a hand wheel and scale.
• Zero-point calibration ensures accurate and repeatable settings.

Material Options (Jaw Plates & Liners)

• Hardened steel
• Tungsten carbide
• Heavy metal-free steel
