How does a gyratory cone crusher work?
Gyratory crushers work on a similar principle to jaw crushers but have a circular gap. Rock is compressed between a static conical bowl and a concave mantle which oscillates about the central axis. These are generally designed for primary crushing in large-scale rock crushing applications up to 6000 t/h.
What’s the difference between a jaw crusher and a gyratory crusher?
The gyratory crusher is mainly used for coarse crushing of various hard material in the primary crushing stage, but it is not suitable for crushing viscous ore. Jaw crusher can crush high moisture, viscous ore, and not easily blocked.
How do you size a gyratory crusher?
Primary gyratory crushers are designated by two numbers. These are the size of the feed opening (in inches) and the diameter of the mantle at its base (in inches). A 60″~x~89″ crusher would have an opening dimension of 60 inches (152 cm) and a diameter across the base of the mantle of 89 inches (226 cm).
What are the types of crushers?
There are several types of primary crushers, including:
- Gyratory Crushers.
- Jaw Crushers.
- Hammermills.
- Horizontal Shaft Impact Crushers.
- Sizers.
- Roll Crushers.
- Cone Crushers.
- Feeder-Breakers.
In which principal gyratory crushers are working?
Gyratory crushers work on the same principle as cone crushers (Figure 4.4(c)). These have a gyratory motion driven by an eccentric wheel. These machines will not accept materials with a large particle size and therefore only jaw or impact crushers should be considered as primary crushers.
What is a mantle in a gyratory crusher?
The mantle which is the movable working surface, is pivoted at its top within a spider bearing under the cap of the spider arm assembly while the bottom is gyrated within an eccentric bushing which is powered by the drive assembly.
What is gyratory crusher used for?
Jaw and gyratory crushers are used for initial size reduction to convert big rocks into small stones. This is generally followed by a cone crusher.
What is gyratory crusher?
Definition of gyratory crusher : a mill for crushing ore or rock or other materials that consists of a cone-shaped burr rotating in the throat of a broad stationary funnel.
What is the product size of gyratory crusher?
8.2. 1 Crushers
| Crusher type | Typical process stage | Typical maximum product size (mm) |
|---|---|---|
| Gyratory crusher | Primary | 200–300 |
| Jaw crusher | Primary | 200–300 |
| Horizontal impact crusher | Primary/secondary | 200–300 |
| Cone crusher | Secondary | 60–80 |
What is a gyratory crusher?
A gyratory crusher includes a solid cone set on a revolving shaft and placed within a hollow body, which has conical or vertical sloping sides. Material is crushed when the crushing surfaces approach each other and the crushed products fall through the discharging opening.
What are primary crushers?
Jaw crushers are mainly used as primary crushers. Their main purpose is to reduce the material to a small enough size that it can be transported by conveyors to the next crushing stages. As the name suggest, jaw crushers reduce rock and other materials between a fixed and a moving jaw.
What is jaw crusher?
A jaw crusher is a large piece of equipment that’s used in mine and ore processing plants to crush rocks. The equipment was first introduced back in 1858 by inventor Eli Whitey Black who primarily developed machinery used for crushing stone.
How does Crusher work in the mining?
Inside the crusher, a piece of steel, known as the mantle, rotates eccentrically. As the material is loaded into the crusher, the mantle rotates, forcing the material against a stationary piece of steel, known as a bowl. The machine generates incredible amounts of force, which crush the material as it settles between the mantle and bowl.
What is the cone crusher used for?
Cone Crusher for Stone Quarry. Crushing machine is the key equipment in stone quarrying operation.
What are the characteristics of cone crusher?
Largest head displacement provides greater capacity
What is roller crusher?
Roller Crusher is widely used for fine or superfine crushing in the industries of mining, construction materials, metallurgy, chemical industries and so on. It can crush all kinds of materials under middle hardness, such as ore, rock, coke , coal, clinker , ceramic raw materials, slag, refractory materials, chemical materials and so on. DOWNLOAD PDF.
