Description

CS) CONE CRUSHER

one

The invention relates to the crushing of materials and is intended for use in the mining, mining and chemical industries, as well as in the building materials industry.

The known cone crusher / having a vertically rotating cone, a stationary cone-bowl, facilities for feeding and unloading, driving a working cone and an eccentric to provide a swinging movement of the cone 1.

However, this cone crusher is used for crushing and grinding relatively hard materials.

Closest to the invention of the technical essence is a cone crusher, containing a crushing movable cone with upper and lower bearing bearings of the shaft, whose axis of rotation is parallel to the axis of the crusher 2.

However, in a known cone crusher, the destruction of the material occurs unevenly, a significant amount of overmilled product is formed and it is practically impossible to control the crushing process, whereas very often in the mining industry it is necessary to obtain a product of strictly defined size,

Both the upper and lower bounds of the size of the pieces, for example, should be limited (in the production of high-quality rubble or in the preparation of coal, slate for burning them in fluidized bed furnaces).

The aim of the invention is to increase the efficiency of crushing by reducing overgrinding of the finished product.

to

This goal is achieved by the fact that a cone crusher containing a crushing mobile shaft with upper and lower BEARING shaft supports, the axis of rotation of which is parallel to the crusher axis, is equipped with additional crushing cones and levers for adjusting the center distance of the crushing cones.

The number of crushing cones is

20

4-8.

Figure 1 schematically shows a cone crusher, a general view; figure 2 - the same view in the lan.

The crusher consists of the main box 25 of the cone 1 with vertical cones rotating in one direction, cones 2, the number of which is 4-8. The cones at both their ends are in bearings 3. The bottom wheel 30

There is no connection to the drive 4. For adjusting the distance, and therefore the toughness of the finished product, there are market exchanges J

Cone crusher works as follows.

The material to be crushed enters the meduconus space 6. At the same time, small pieces of the source material pass through it almost unrestricted, while the larger ones are captured by the working surfaces of the cones and are destroyed. All the cones rotate in one direction, while the material is unloaded in a counter-impact mode and therefore is located in the central part between the cones.

The number of cones is selected based on the physicomechanical properties of the material being processed. More clay ores require a correspondingly larger number of crushing cones in order to avoid material compression.

Starting from the crushing mechanism in a crusher of this type, the maximum number of cones should not exceed 8.

This invention allows to increase efficiency by reducing the crushed material, reduce power consumption, reduce the amount of waste, as well as simplify the crushing technology, including the hardness of the material.
