A cone crusher is a specific type of crushing equipment, able to crush any type of medium-hard raw materials and ores. Although its design and working principle are very identical to the jaw crusher, the cone crusher provides the contractors with less owning and operating costs and is easier to adjust to a specific application. The cone crusher has a stable structure and is made from heavy-duty materials, increasing its already-high-efficiency significantly. It is most commonly used as a secondary crushing equipment, because it is almost inefficient to crush hard materials as a primary crushing equipment.
The cone crusher is composed of a crushing cone, bowl-shaped bearing, a transmission device, a hollow eccentric shaft and rigid frame. As mentioned, the cone crusher is easily adjustable – the operators can adjust the discharge opening by the hydraulic pressure station and springs, in order to get materials of the desired size.
The cone crusher has a unique working principle in many terms. Many operators suggest that it can be used for primary crushing and final crushing as well, but it is most efficient for secondary crushing. The easy maintenance and lower costs are only boosting its popularity, while its high production is making the cone crusher a favourite crushing tool. The cone crusher plays an essential role in few different industries, especially in the construction and metallurgical industry.
The working principle of the cone crusher is very similar to the gyratory crusher. The shaft of the cone crusher is driven by a powerful motor which forces the axle of the cone crusher wings to swing, so the crushing walls, known as a mantle and a bowl liner, are face to face. This zone is called the crushing zone. The cone crusher breaks the raw material by squeezing it between its walls, which are completely covered with resistant mantle and a bowl liner. The raw material is getting squeezed at the exact moment it enters the area between the mantle and the bowl liner.
When the raw material is pressed and crushed for the first time, it reaches the next crushing process and it is pressed and broken again. Materials of the desired size drop through the discharge opening at the bottom of the cone crushing. This same process continues until the materials are into the desired small pieces. When compared with all other crushers, the cone crusher working principle is the most efficient.
