What are the types of crushers?
Types of crushers
| Type | Hardness | Reduction ratio |
|---|---|---|
| Jaw crushers | Soft to very hard | 3/1 to 5/1 |
| Gyratory crushers | Soft to very hard | 4/1 to 7/1 |
| Cone crushers | Medium hard to very hard | 3/1 to 5/1 |
| Compound crusher | Medium hard to very hard | 3/1 to 5/1 |
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.
What is the working principle of gyratory crusher?
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 is black jaw crusher?
The original crusher of jaw type. A crusher with one fixed jaw plate and one pivoted at the top so as to give the greatest movement on the smallest lump. Motion is imparted to the lower end of the crushing jaw by toggle joint operated by eccentric.
Which type of crusher is best?
Gyratory Crushers are an excellent choice for a primary crusher, as they can handle very hard and abrasive material. They are ideal for dry to slightly wet material but not sticky material. Gyratories are compression crushers primarily used for heavy mining and quarried materials in extremely high tonnage applications.
How is 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.
What is the principle of jaw crusher?
The working principle of jaw crushers is based on the reciprocating movement of the movable jaw that compresses and crushes the rock or ore between itself and the fixed jaw, as the material enters the zone between the jaws.
What is the product size of gyratory crusher?
5.4. Gyratory Crusher Operation
| Size Gape × Dia. of Mantle (mm) | LMAX (Open Set) (mm) | Capacity (Production) (t/h) |
|---|---|---|
| 1371 × 1879 | 137–223 | 3100 |
| 1828 × 2311 | 194 | 2750 |
| 1524 × 2268 | 200–275 | 3200 |
| 1524 × 2268 | 238–275 | 3180 |
What is Pitman in jaw crusher?
The pitman usually denotes a connecting rod, but in a jaw crusher it does not connect two things. Here, it refers to the moving jaw in a jaw crusher. It achieves the reciprocating movement through the eccentric motion of the flywheel shaft. This creates enormous force in each stroke.
What are the three types of crushers?
Crushers are classified into three types based upon the stage of crushing they accomplish. These are (i) primary crusher, (ii) secondary crusher, and (iii) tertiary crusher.
What is cone crusher?
Cone crushers are popular rock crushing machines in aggregates production, mining operations, and recycling applications. They are normally used in secondary, tertiary, and quaternary crushing stages.
