· For reducing the rock blocks into 4–5 cm particles and having the same crushing for all samples before the last crushing, the samples were crushed by JC. Then, rock samples were crushed by two rock crusher according to the typical crusher in Iran,, JC and HSI. The HSI and JC are shown in Fig. 3. Two types of crusher are used, separately.
02/11/2021 · While cone crushers are usually supported at the base, gyratory crushers are suspended. Impact crushers, sometimes called "hammer crushers," use mass and velocity to break up pieces with a blow bar or hammer that strikes a stationary plate. When the rock hits the plate or anvil, it breaks on natural stress lines to create a uniform product.
