Cone Crusher Overview

Hongji Mine Machinery cone crusher is a machine used for breaking the big rocks into the minor rocks, gravels or rock dusts. It is widely used for medium and fine crushing all kinds of rocks with pressure under 350MPa in mining, cement industries, sand industries and other areas. The perfect combination of high-performance crushing chamber and high crushing frequency improves the handling ability of the cone crusher to a great degree.

Cone crushers are also known as cone breakers. Compressive strength of cone crusher is no more than 250MPa. Cone crusher is widely used in mining, metallurgy, building materials, chemicals and other sectors to crush hard and medium hard materials. Cone crusher is ideal for medium and small concentrator ore breaking or crushing. The spring overload protection device allows tramp through the crushing chamber without damage to the machine.

Hongji is one of the famous hydraulic spring cone crusher suppliers, symons cone crusher manufacturers in China. The rock cone crusher prices are very low. Welcome to choose Hongji Mine Machinery product.

Technological Development of Cone Crusher

The design process of cone crusher has always been slow, which has lasted for almost 60 years. Some reliable productions have been used for reference in the basic design of cone crushers. The greatest changing lies in the improvement of rotating speed. For example, a 48-inch (120 cm) Cone Crusher in 1960 can produce 170 tons of gravels per hour, while the cone crusher with the same size today can produce 300 tons per hour.

The improvements come from the enhancement of speed, as well as some better design of crushing cavity. Another great development of cone crusher exists in the application of hydraulic techniques, which can prevent the uncrushed materials from getting into the crushing cavity. The uncrushed materials such as steel can cause great damage and more cost to the crusher when getting into the cavity. The development of hydraulic cone crusher reduces much downward time and prolongs the life of these machines.

Stucture of Cone Crusher

Cone crusher consist of frame, transmission device, hollow eccentric shaft, bowl-shaped bearing, crushing cone, springs and hydraulic pressure station for adjusting discharge opening.

Working Principle of Cone Crusher

When the cone crusher is working, the engine rotates around a fixed point through the belt wheel or the coupling, meanwhile the transmission shaft and the conical part of the cone crusher are taken under the force of the eccentric bushing, which makes the crushing wall close to the pierced mortar wall at intervals. Then, the ores will be impacted, squeezed and bent constantly in the crushing chamber, resulting in the crushing of the ores.
