Symons cone crusher (spring cone crusher)

Symons cone crusher is also called spring cone crusher, it is the first generation cone crusher in China. The working performance are very stable.

Input Size: 0-300mm
  Capacity:  45-350TPH
  Material: Granite, diabase, basalt, pebble, limestone, dolomite, metallic ores and non-metallic ores, etc.



 

Description

Symons cone crusher (spring cone crusher) can crush materials of above medium hardness. And it is widely used in metallurgy, building, hydropower, transportation, chemical industry, etc. When used with jaw crusher, it can be used as secondary, tertiary or quaternary crushing. Generally speaking, the standard type of Symons cone crusher is applied to medium crushing. The medium type is applied to fine crushing. The short head type is applied to coarse fine crushing. As casting steel technique is adopted, the machine has good rigidity and large high strength.

Working principle

A cone crusher breaks rock by squeezing the rock between an eccentrically gyrating spindle, which is covered by a wear-resistant mantle, and the enclosing concave hopper, covered by a manganese concave or a bowl liner. As rock enters the top of the cone crusher, it becomes wedged and squeezed between the mantle and the bowl liner or concave. Large pieces of ore are broken once, and then fall to a lower position (because they are now smaller) where they are broken again. This process continues until the pieces are small enough to fall through the narrow opening at the bottom of the crusher.

Product Advantage

1. Big ratio of crushing, high efficiency crushing, high productivity and output size unique

2. Simple structure, stable operation, convenient adjustment, less stopping time, lower cost running

3. Service life is long because of reasonable raw material selecting and structure designing.

4. Grease or water sealing adopted, isolating the stone powder and oil, making work reliable

5. Spring over-load protection ensuring machine not damaged by the metal passing through the crusher
