Jaw and gyratory crushers are the most common types of primary compression crushers. Each applies a compressive force to rock particles as they come in contact with the crushing surfaces. The force is applied slowly (in comparison to impact machines) resulting in abrasion and cleavage fracture.
Electric Pulse Fragmentation (EPF) is an innovative technology that uses High-Voltage Pulsed Power (HVPP) for the selective comminution of a material. This paper aims to compare a beneficiation flowsheet including an EPF treatment in the comminution circuit to a conventional pathway where the EPF step was replaced by a series of jaw crushers. …

The heavy-duty machines use in the first mechanical stage of comminution are mainly jaw crushers. The pivoted jaw swings around the pivot and makes an impact on the fixed jaw, crushing the fed lumps in the jaw crusher. In order to decrease the replacement cost, choose the right material for your jaw crusher is the first thing.

pulverizer. Figure 3 illustrates the angle of nip in a jaw crusher. Figure 3: Angle of nip in a jaw crusher 2.3 Crusher Jaw Plates Compression of materials undergoing crushing in a jaw crusher is achieved when the movable jaw presses the feed against a stationary jaw. These jaws can be flat surfaced or corrugated.
The original Blake crusher was designed with a vertical stationary jaw. Probably the first departure from this arrangement was an 84 X 66″ crusher, built in 1914. This machine conventional design, in that …
The first principle states that comminution calculations should be based upon the energy register of the feed and product, and that in any instance the specific energy input equals the energy register of the product minus …
The two most common primary crushers used for coarse run-of-mine material are the jaw and gyratory crushers. Secondary crushing; includes all operations for reclaiming the primary crusher product from ore storage to the disposal of the final crusher product, which is usually between 0.5 and 2 cm in diameter.
The physical and mechanical properties of the rock depend on various factors, such as water saturation ... Saramak, D., and Naziemiec, Z., Stochastic modeling and control of comminution processes in jaw crushers, IMPC 2006—Proceedings of the 23rd International Mineral Processing Congress, Istanbul, 2006.

Improved energy utilization of a comminution process can be achieved through two general approaches: 1. Pre-treatment of the material to be crushed in order to obtain lower Bond index values ( Wi ). This approach implies the measurement of variations in the Bond Work index values during the pre-treatment of the material to be crushed.

2.1 Primary Crusher Primary crushers are heavy duty rugged machines used for crushing Run-of-Mines ore (–) 1.5 m and convert them into stones of size 100–200 mm in dimension to make them suitable for further crushing process. Most commonly used primary crushers are gyratory and jaw types.
The mechanism of movement of rocks down the crusher chamber determines the capacity of jaw crushers. The movement can be visualised as a succession of wedges (jaw angles) that reduce the size of particles progressively by compression until the smaller particles pass through the crusher in a continuous procession.

Primary crushing is the first stage in the comminution process and involves breaking down large rocks into smaller pieces that can be handled by the downstream machinery. Secondary crushing, on the other hand, is the second stage in the comminution process and involves breaking down the material further into smaller pieces.
