Which of the following is the capacity of a roll crusher?
3 to 300 T/hr
Explanation: The capacity of a roll crusher is 3 to 300 T/hr and the roll speed ranges from 50 to 300 revolution per minute.
What is the maximum reduction ratio of a roll crusher?
Roll crushers have a theoretical MAXIMUM reduction ratio of 4:1. If a 2 inch particle is fed to the roll crusher the absolute smallest size one could expect from the crusher is 1/2 inch. Roll crushers will only crush material down to a minimum particle size of about 10 Mesh (2 mm).
What is Taggart law for jaw crusher?
One of the most famous empirical formulas is based on the fact that the performance of a single-toggle jaw crusher is directly proportional to the area of the charging opening described by F. Taggart in 1927 [16]: BL Q ⋅⋅ = 930 , where L and B are the length and the width of the jaw crusher charging opening, m.
What is the maximum feed size in secondary crusher?
8.2. 1 Crushers
| Crusher type | Typical process stage | Maximum feed size (mm) |
|---|---|---|
| Jaw crusher | Primary | 1400 |
| Horizontal impact crusher | Primary/secondary | 1300 |
| Cone crusher | Secondary | 450 |
| Cone crusher | Tertiary | 150 |
What is use of roll crusher?
Roll Crushers are designed to handle the primary, secondary and tertiary stage crushing of friable materials such as coal, salt, clay, bauxite, limestone and other minerals of similar characteristics in the mining, power generation and numerous other industries.
How do you calculate the reduction ratio of a crusher?
Ideally, the reduction ratio of a jaw crusher should be 6-to-1. There are different ways to calculate reduction ratio, but the best way is something called the P80 factor. The reduction ratio is then calculated by comparing the input feed size passing 80 percent versus the discharge size that passes 80 percent.
Which mode of size reduction is used by jaw crusher?
compression
Size reduction in jaw crushers occurs mainly by a compression mechanism and to lower extent by impact. While in a jaw crusher breaking of feed lumps takes place mainly by compression, some crushers operate on an impact principle.
How do you calculate reduction ratio?
(11.4) and so Ei is the amount of energy required to reduce unit mass of the material from an infinitely large particle size down to a particle size of 100μm. It is expressed in terms of q, the reduction ratio where q = L1/L2. Note that all of these equations [eqns.
What is the reduction ratio of crusher?
Generally, for such a case, the split would be about 3:1 to the standard machine, and 4:1 to the fine reduction crusher….Approximate Crusher Reduction Ratio. F/s*
| Crusher Type | Smaller Models | Larger Models |
|---|---|---|
| Jaw crusher | 3-20 | 3-10 |
| Gyratory crusher* | 2½—14 | 6—10½ |
| Cone crusher* | 3¼—16 | 5-16 |
