Crushers, Pulverizers & Mills. Particle-size reduction, or comminution, is often required to prepare bulk material samples for testing. Crushing is often the initial step with materials such as mineral ores or aggregates using varying combinations of force, impact, and compression to initiate fracturing in the materials.

Compression crushers are used to break rocks and coarse particles larger than 3 cm in diameter. There are three main types of compression crushers: jaw crushers, gyratory crushers, and rolls. Equipment Design Jaw Crushers. Jaw crushers consist of a rectangular frame with a fixed jaw plate and a jaw stock carrying the moving jaw.

There are two crushing machines available; a jaw-crusher and a disc-pulverizer. Samples are usually run through the jaw-crusher first, and then the pulverizer. If the sample is …

Predictions for five types of crushers: jaw crusher, cone crusher, gyratory crusher, impact crusher and double roll crusher are presented. The breakage method used is based on facture of particles using geometric rules for progeny generation and estimates of the force applied to the particles as they flow through the crusher.

Table Source: Wikipedia (Crushers) Cone crushers use a spinning cone that gyrates in the bowl in an eccentric motion to crush the rock between the cone surface, referred to as the mantle, and the crusher bowl liner.Gyratory crushers are very similar to cone crushers, but have a steeper cone slope and a concave bowl surface. As the gap …

to a design that exposes the inner workings of the crusher and allows for ease of cleaning and maintenance of the equipment (fig. 1). The jaw crusher works by compressing and shearing rock cobbles between a swing motion plate and an immovable plate. The two plates are referred to as the "jaw."

Jaw Crushers. Reduction ratio - 6:1. Jaw Crushers use pressure to break up very hard, flaky, and slabby rocks by passing them between a moving surface and a stationary one. They are generally used for primary crushing but also provide great results with secondary crushing. Jaw crushers are excellent for breaking up concrete, rock and asphalt.

There are only two steps! Step one: Remove and break up concrete on your job site into workable pieces. You can do this by attaching a hydraulic breaker to your excavator.
