With low grade ore deposits requiring higher power and higher throughputs than ever before, you need a crusher that can take the impact – without compromising on efficiency.
A cone crusher is similar in operation to a gyratory crusher, with less steepness in the crushing chamber and more of a parallel crushing zone. A cone crusher breaks material by squeezing it between an eccentrically gyrating main shaft, which is covered by a wear resistant mantle and the concave hopper, covered by bowl liner (concave).
The gyratory crusher consists of a cone-shaped crushing head mounted on a vertical shaft. The vertical shaft hangs from the top of the crusher and is supported by a spider.

Gyratory crusher comes in three basic types: fixed shaft type, slant discharge type, and central discharge type. The central discharge type (Fig. 1) is quite common. Gyratory …
The main shaft of the ETCL Primary Gyratory Crusher is hydraulically supported, ensuring easy automatic setting of the crusher gap and discharge of tramp material.
Gyratory crusher achieves discharge port adjustment and overload protection in two ways: (1) In a mechanical crusher that uses mechanical power, the upper end of main shaft …
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.
Our Gyratory Crusher Pro is the backbone of crushing technology and guarantees you the best efficiency and quality in primary crushing in the market.
Essentially, the gyratory crusher consists of a heavy cast-iron, or steel, frame which includes in its lower part an actuating mechanism (eccentric and driving gears), and in its upper part a cone-shaped crushing chamber, lined with wear-resisting plates (concaves). Spanning the crushing chamber across its top is a steady-rest (spider), …
Gyratory Crusher KB 54-75 Pro. imary crushing for capacities above 5,000 mtphWhen it comes to crushing blasted hard rock in ore and natural stone mining, the eficie. of our gyratory crushers is second to none. Our KB Pro range is …
Crushers are machines used to reduce the size of rocks, stones and ore. They are often utilized in aggregates production, construction material recycling and in mining operations. offering covers different gyratory crushers, jaw crushers, cone crushers and impact crushers – optimized for any size reduction need.
On this basis, the impacts of the mantle shaft angle, the concave angle, the eccentric angle, and the mantle shaft speed on the gyratory crusher performance are explored …
For gyratory crusher, the outer circle represents the stationary bowl covered by the concave and the inner circle represents the main shaft covered by the mantle. The main shaft rests in the eccentric bushing at the base of the crusher. As the eccentric rotates, the base of the main shaft moves in a circular path around the …
The gyratory crusher by virtue of its annular discharge opening is an effective slab breaker. This faculty, coupled with the fact that its receiving openings are especially well suited for admitting slabby feed, give it a very definite advantage over the jaw crusher in the handling of such material.

The main features of a Gyratory Crusher include a tall crushing chamber lined with replaceable manganese wear plates, a main shaft with head and mantle, and a spider to anchor the top of the main …
The crushing system with primary gyratory crusher and secondary impact crusher is particularly suitable for compact hard and also abrasive rock. With the preceding coarse reduction, it is possible to use crushing tools made of highly wear-resisting cast-steel in the secondary crusher (austenitic high alloyed cast iron).
The main components of a gyratory crusher include the mantle, the concave surface, and an eccentrically mounted rotating shaft. The mantle is located on the top of the shaft and is connected to it via …
With a huge feed opening, the Jaw Gyratory Crusher Pro is the ideal mining primary jaw crushing option for high capacities and large chunks of material.
The main features of a Gyratory Crusher include a tall crushing chamber lined with replaceable manganese wear plates, a main shaft with head and mantle, and a spider to anchor the top of the main shaft bearing.
Resistant U-shaped arched spider, durable manganese bronze spider bushing, new shell separators and inspection ports, as well as hardy one-piece main shaft makes the Superior™ MKIII 60-89 primary gyratory crusher efficient and …
The gyratory crusher model is PXZ1417, and its specific structure is shown in Fig. 1. The crusher is composed of external shell, mantle shaft, sliding bearing, friction disc and other parts.
Gyratory crusher achieves discharge port adjustment and overload protection in two ways: (1) In a mechanical crusher that uses mechanical power, the upper end of main shaft has an adjusting nut. If the adjusting nut is rotated, the crushing cone can rise or lower, and the discharge port becomes bigger or smaller.
