Jaw crushers are widely used in primary crushing. They rely on compression: two jaw plates move back and forth to crush large rocks into smaller fragments. While effective at reducing rock size, they tend to produce angular, flat, and elongated particles, often referred to as laminar aggregates. VSI Crushers: The Master of Shape

Jaw crushers are the most common solution in underground applications when the throughput is below 1000 tonnes per hour, depending somewhat on the scalping solutions.

2. The Role of Jaw Plates. At the heart of a jaw crusher are two jaw plates – one fixed and the other movable. These plates act as a funnel, guiding the material to be crushed into the space between them. As the movable jaw exerts a force on the rock, it presses it against the fixed jaw, gradually breaking it down into smaller pieces.
