A cone crusher is a machine used in mining and construction to break medium to hard rocks into smaller pieces. It has a unique design that filters and crushes rocks quickly. The machine is powered by electric or diesel motors and is limited to handling material 3 inches in diameter or less. It is primarily used in the mining industry but also in construction and demolition.
A cone crusher is an essential part of the process of breaking rocks into smaller pieces. The unique design of this cone-shaped machine filters and crushes rocks in a fraction of the time it would take a person to do the job by hand. These machines are used in a variety of industries, such as mining and construction, and tend to be used on medium to hard rock only.
At first glance, a cone crusher doesn’t look like a cone. It’s actually a large rounded metal container with several industrial strength springs surrounding its body. Cone crushers get their name from their internal mechanisms, where a large amount of rock is contained at the top, but the opening narrows towards the bottom, where the actual crushing takes place. Crushing takes place between the central shaft and a crushing plate, called the mantle.
The cone crusher is powered by electric or diesel motors driving a belt-driven turbine. These are very powerful engines, because a great deal of force is required to crush rocks. A cone crusher’s belt drive turns a central axle called a shaft, which travels in an oblong, eccentric pattern and is attached to the mantle. The oblong spinning allows for periodic openings in the space between the mantle and the walls of the crusher. Rocks in this location are pressed against the walls by the mantle, broken into smaller pieces, and then filtered by the cone system.
A cone crusher can handle a large amount of material with its immense power, but it’s actually quite limited in range. Most cone crushers are an intermediate stage in the crushing process, receiving rocks that have been crushed by machines that specifically handle larger rocks. Most crushers only handle material 3 inches (7.6 cm) in diameter or less. Additionally, the system is limited to medium-hard rock and minerals due to the strength of the materials performing the crushing.
Primarily, the use of a cone crusher is in the mining industry, but it is used in other situations as well. One of the primary ways a mining company uses this tool is to facilitate easier movement of carved rock from mine shafts. Similarly, construction and demolition crews use a crusher for the same purpose when excavating a particularly rocky area. Many times, a secondary industry is created from the crushed rock by selling it as gravel for driveways.
