Gyratory crusher is a crushing equipment that uses the gyratory motion of the crushing cone in the conical cavity inside the shell to extrude, bend, and impact materials, for the purpose of coarse crushing of the materials of various hardness. It was invented in the USA in the 1870s. The equipment specification is usually represented by …
Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 30-45%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.
A mining crusher is a machine used to reduce large rocks into smaller pieces. Crushers are designed to handle a range of materials. It is from ores to coal and various minerals used in the mining industry. There are several types of crushers commonly used in mining operations: Jaw Crusher. Gyratory Crusher.
The cone crusher has a high reduction ratio, ensuring efficient material crushing. Discharge: This is the final stage of the crushing process. When the material is crushed into the preferred size, it exits the cone crusher through an opening at the bottom. The entrance is located between the mantle and the bowl liner.
The gyratory crusher works on the same principle as the jaw crusher but has a conical head and a concave surface. The crushing chamber is lined with a hardened manganese steel material. The rock crushing is caused by a circular movement in the crushing surface and the materials are progressively crushed until they are of a smaller …
