Cone and gyratory crushers. Cone crushers and gyratory crushers are also compression-type machines that crush material between a moving piece of steel and a stationary piece. The output is controlled by the setting between the two pieces of steel. Though the chamber is round in shape, the moving piece of steel is not meant to rotate.
Compression crushers. Jaw crushers Jaw crushers are often used as primary crushers and are perhaps the most popular crusher worldwide. They are suitable for almost any type of material. Crushing takes place between a stationary jaw plate and a moving jaw plate. The moving jaw plate is mounted on the pitman, which is given a reciprocating motion.
This ratio is known as the Aggregate Crushing Value (ACV) and can be calculated using the following formula: Aggregate Crushing Value (ACV) = (W2 x 100) / (W1 - W) Example limits. Here is a list of the Aggregate Crushing Value limits for different types of road construction: Types of Roads / Pavements: Flexible Pavements. Water bound macadam: 40
