Since crushing is done between conical surfaces, the crusher is also called “cone crusher”.

Both in terms of size and structure, many different shapes are encountered today. There are two main types in general: “movable national” and “fixed national”.

Body Structure: The body consists of two parts, the upper and lower. The inner surface of the upper section is covered with concave. It is in the form of an inverted truncated cone.

According to the size of the breaker, it is reinforced with horizontal and vertical belts. It is made of cast iron or cast steel.

In very large Cone crushers , they are made in pieces, and the parts are added together with strong and thick bolts, and the body is formed.

The lower part of the body is a protector and carrier. The bolts to which the hammer is attached to the foundation are passed through the holes located here.

It has a structure suitable for placement of the eccentric sleeve and bevel gear in the middle part where the lower extension of the shaft enters. This part also carries the main drive pulley and the shaft (pinion shaft) bearing.

Like the upper compartment, it can be reinforced with vertical and horizontal belts depending on the size of the hammer. A groove structure suitable for the broken goods to come out of the Cone Crusher is also part of this section.

The upper and lower sections of the body are connected by bolts passing through their mutual flanges.

Mouth Ring and Bridge: The upper end of the body is surrounded by a mouth ring. The bracelet also carries the bridge, which is suitable for the upper end of the hub to pass.

The mouth plate is covered with a wear plate (liner) as the material is fed to the crusher through the upper mouth of the body. The mouth and bridge can be built in one piece.

Since the bridge closes the entrance mouth as little as possible is crucial for breaker blockages, it is curved upwards and has two or three legs. The top of the feet is covered with protective plates (lining) against impacts and wear.

Mouth collar lining and bridge foot lining are usually made from the same material as concave. In the middle of the feet, the egg-shaped part has a structure where the upper end of the hub shaft will enter.

If the main shaft is of the type suspended from the bridge, this section has a structure according to it.

With the eccentric movement, a spherical bearing structure is noticeable here, since the shaft is constantly making a secretion.

Also included in this section is an adjustment device that allows the hub to be pulled upwards to accommodate wear and adjust the throat opening.
