The walls of the gyratory crusher's hopper are lined with "V-shaped" pieces, the mantle and the concave, like a jaw crusher but shaped like a cone. The ore is discharged through the smaller bottom output hole of the cone. While the cone does not move, an interior crushing movement is created by a revolving shaft on a vertical rod.

For the gyratory crusher mantle, Qiming Casting gives two choices: Standard manganese steel and TIC inserts manganese steel. Manganese steel is a high-strength alloy steel that contains around 12-14% manganese. It is a tough and wear-resistant material that can withstand high impact and abrasion. Manganese steel is also able to work hard ...

Gyratory Crusher. A gyratory crusher consists of a movable and truncated conical head and a fixed concave shell, as is presented in Figure 1. The head is integral with the main shaft, and it is covered by an element of wear named mantle. The set of these parts is the main shaft assembly.

In lowest position with a new mantle and new concaves, there is about 1" (25mm) of oil under the piston • In highest position the minimum distance between the head nut and the spider is 1" (25mm) • The mainshaft positioning system is only used to compensate mantle and concave wear, not to change the crusher setting.

Gyratory Crushers are used for crushing ore in mining.Gyratory crushers are designed to handle large rocks and ores with high hardness and toughness. Proper design of both gyratory crusher mantle and concave liners leads to lower and more consistent crushed product size, better throughput, highly predictable liner changeout intervals and overall …

At this level Throw = OSS – CSS A crusher that has a 20cm throw is one where the mantle surface approaches and recedes from the concave through a distance of 20cm as measured at the level of the choke point. Another factor which governs the proportions of the crushing chamber is the maximum permissible angle between the two …

The crusher head is at the moment in the close-side position. Crusher Working Principle. As the head recedes on its opening stroke, the body of material moves downward; until, at the end of the stroke, the plane has moved to position "1.". Note that the length of line "1″ from concave to open-side head position, is the same as that of ...

Gyratory crushers are one of the main pri-mary crusher types used in mines and quar-ries. The size designation of gyratory crushers is based on the size of the feed opening …

On the other hand, by utilizing data from DEM simulations, the crushing power can be calculated with the contact information between particles and the mantle in terms of the crushing torque [16].

A cone crusher consists of a fixed conic liner called concave and inside it a smaller moving liner called mantle. The mantle is suspended on an eccentrically rotating shaft.

The other most noticeable change is the crushing action of the mantle. In the Gyratory all the movement is in the bottom of the …

The surface of the mantle shaft and the shell is fixed with many liners, and they are eccentrically installed. The space enclosed by the outer surface of the mantle shaft and the inner surface of the shell is the crushing chamber. When the gyratory crusher starts to work, the pinion shaft assembly drives the eccentric rotation of the mantle shaft.
