Cone crusher can crush hard, medium hard and many types of materials, mainly used for medium and fine crushing of materials. Therefore, the product particle size is more uniform. The crushing cavity of the cone crusher has different design types, each of which is most suitable for a specific application range and material. It can be divided into standard head components and short head components. This article shares the difference between standard head and end cone crusher.
The difference between standard and short head
Different shapes (size and volume) of crushing cavity
The standard and short head components have the same construction, but the shape and volume of the crushing cavity are different.
The head flaring (the angle between the head and the concave) of the crushing chamber of the standard head cone crusher is larger. Designed to crush feed materials up to 300 mm.
The short-head cone crusher is a modification of the standard-head cone crusher. A special split cone and concave ring are designed. The angle between the head and the concave is smaller and the crushing cavity is more parallel. The more compact chamber makes the short head cone crusher more suitable for crushing smaller size materials. The maximum feed size is 120mm.
Different granularity of finished products
The standard head cone crusher has a coarser discharging granularity and a high output. The discharging size is 20-40 mm. The crushed material can be used for intermediate crushing.
The finished material size of the short head cone crusher is smaller. Generally, the short head cone crusher is used after the intermediate crushing.
Closed-side setting is different
The CSS(closed side setting) application scope of standard head cone crusher is larger, so the processing capacity of standard cone crusher is larger.
Whether it is standard head or short head cone crusher, their working principle is basically the same.
When to use standard head and when to use short head?
The feed material and final product size determine the choice of standard or short head.
The standard head is used for secondary or tertiary crushing (medium crushing). The maximum feed size is 300 mm, and the discharge size is about 20-40 mm.
The short head cone crusher can be used for tertiary or quaternary crushing (fine crushing). The maximum feed size is 120 mm, and the output size is 5-20 mm.
There are three designs for standard head and end cone crusher: “coarse”, “medium” and “fine”. Based on the size of the final product, select the corresponding design and set the corresponding CSS.
The standard cone crusher has a large head angle, coarser discharge and higher output. It is generally placed behind the rough crusher (jaw crusher or gyratory crusher) for medium crushing. The head angle and the size of the discharge port of the short-head cone crusher are relatively small, and a finer product size can be obtained. Generally, the short-head cone crusher is used as a fine crusher and placed after the middle crusher.
