Dehong cone crusher are normally used as a secondary crusher but can be used as a primary crusher if used in processing a sand and gravel deposit. Normally a jaw crusher is used for the initial or primary crushing of larger rocks. To see an illustration of the difference between a standard cone crusher and a shorthead or fine crusher, and to see what the inside of a cone crusher looks like, including an animation of a cone crusher working

A typical standard head cone crusher has an average reduction ratio of 6-10:1. That means an average rock will be fractured into 6-10 smaller rocks after passing through a cone crusher. A short head , also known as a fine cone crusher, typically has a 4-6:1 ratio.

The maximum size of your target final product will be a good guide to whether you need a standard or fine cone crusher, either as a secondary crusher or a tertiary crusher.

Cone crusher capacity is primarily determined by the closed side discharge setting and the diameter of the cone. The greater the diameter and discharge setting the greater the capacity. Conversely, the smaller the diameter and discharge setting, the smaller the capacity.

In all types of crushing the greatest capacity can be achieved if the maximum final product size and everything smaller is scalped (removed) prior to being fed into the crusher. That will increase capacity and wear life of the wear parts.

It is also important to properly feed the cone crusher. The feed chute should be arranged to provide a uniform and consistent amount of feed material so it is distributed evenly around the head and keeps the crushing chamber filled at all times if possible.

The application of PYZ 1200 cone crusher animation crushing machine

Cone crusher is generally used as a secondary crusher in a crushing circuit. Pre-crushed product(usually 3in minus depending on the cone crusher model) is fed through the top of the cone crusher and flows over the mantle. The vertical cone crusher drive shaft ratates the mantle eccentrically below the concave, or bowl liner, squeezing product and crushing it between the mantle and concave. Cone crushers are usually run on belt drives driven by an electric motor or diesel engine. Cone crushers are used extensively throughout the aggregate and mineral processing industry.

When the crusher works, motor drives eccentric cover to rotate by flexible coupling, transmitting shaft, and a pair of bevel gears. Crushing cone central line moves cycloidally driven by eccentric cover, so the crusheing wall and fragment wall sometimes approach to each other, and sometimes depart from each other. By doing this, materials are crushed between the crushing wall and fragment wall.

1. Large crushing ratio and high working efficiency.

2. Perfect lubrication device guarantees machine reliability.

3. High quality wear-resistant parts reduce operating cost.

4. Long life and large application.
