What is cone crusher?
A Cone Crusher is a compression type of machine that reduces material by squeezing or compressing the feed material between a moving piece of steel and a stationary piece of steel. The crushed material is discharged at the bottom of the machine after they pass through the cavity.
How many types of jaw crushers are there?
There are two basic types of jaw crushers: single toggle and double toggle. In the single toggle jaw crusher, an eccentric shaft is on the top of the crusher. Shaft rotation causes, along with the toggle plate, a compressive action. A double toggle crusher has two shafts and two toggle plates.

How does a gyratory crusher work?
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 is the difference between jaw crusher and cone crusher?
Jaw crushers can work on a range of stone from the softer ones like limestone to harder basalt or granite. A cone crusher is similar to a gyratory crusher because it operates using a mantle that rotates within a bowl, but it has less steepness in the crushing chamber.
What is a crusher mantle?
Inside your cone crusher The mantle is a moving part that gyrates in an eccentric motion. That is, it doesn’t remain completely centred – it swings slightly as it rotates, continually altering the gap between the mantle and the concave (the ring outside the mantle that stays fixed in place.)
How is jaw crusher capacity calculated?
Example capacity calculation of a 10″ x 20″ (250 mm x 500 mm):…
- Pp = 2800 (2.8 SG)
- e = 0.2 (halfway between dolomite and sandstone)
- A = 250/1000 x 500/1000.
- Wj = 0.5.
- Nj = 225.
What is the difference between gyratory crusher and cone crusher?
The difference between the two is first the speed that the mantle travels while crushing the ore. In the Gyratory all the movement is in the bottom of the crusher mantle. This is due to the angle that the main shaft is on. The greater angle of the cone crusher puts the pivot point below the distributor plate.
How do you size a jaw crusher?
Jaw Crushers are sized by the top opening of the crushing chamber. For example, a 32 x 54 Jaw Crusher measures 32″ from jaw die to jaw die at the top opening or gape opening and 54” across the width of the two jaw dies. The narrower bottom opening of the crushing chamber is used to size the discharge material.
What is CSS in crusher?
The closed side setting (CSS) defines the reduction ratio in cone crushers and has a significant effect on product gradation, capacity, and power draw. The closed side setting is measured from the bottom of the mantle to the bottom of the bowl liner at their closest point during the gyrating cycle.
