Cone crusher

Cone crusher is a machine used for breaking big rocks into minor rocks, gravels or rock dusts. Cone crusher is mainly used for second crushing; the stone crusher is widely used for all kinds of medium and fine crushing rocks with compressive strength under 350MPa in mining, cement industry, sand industry, metallurgy and other fields. It is especially suitable for materials with Mohs hardness under the range of 5-16, such as iron ore, non-ferrous metallic ore, granite, limestone, quartzite, sandstones, pebbles, etc. Symons cone crusher is suitable for hard and mid-hard rocks and ores, such as iron ores, copper ores, limestone, quartz, granite, etc, so it also called rock crusher. Type of the crushing cavity is decided by the application of the ores. Type is for PYZ (secondary crush); middle type is for PYD (tertiary crush); short-head type is for primary and secondary crush.

Working Principle of the Cone Crusher

When the stone breaker is working, the engine rotates around a fixed point driven by the belt wheel or the coupling. The transmission shaft and the conical part of the cone crusher swing under the force from 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. At last, the whole ore crushing process is finished.

The perfect combination of high-performance crushing chamber and high crushing frequency improves the handling ability of the cone crusher to a greater degree.

Technical Data of Spring Cone Crusher

Advantage 1: Spacer

Increasing or reducing the number of spacer to adjust chew clearance and suspension point height. Adding spacer could change the position of cone lining and principal axis to adjust the gap

Advantage 2: Unique shape of cavity

Material is in the gap of cones to get squeezed, curved and sheared to make process easier and low energy consumption

Advantage 3: overload protection

Overload protection could lengthen service life of machine

Advantage 4: Bearing

Higher speed of operation, even size of final product, cube shape of product, high capacity
