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
Disadvantages of Roll Crushers: a) Reduction ratio is smaller than the other crushers. b) Very large rolls are required to crush small piece of ores, i.e. Capital investment is high. 4 Figure 2. Roll crusher diagram Theoretical Capacity of Roll crusher = (0.0034 * N * D * W * S * ρ) tons/hr

All crushers have a limited reduction ratio m eaning that size reduction will take place in stages. 3.2 Operation stages: The operating stages in
The rule of thumb for the Double Roll Crusher’s ratio of reduction is 4:1. The simplified design gives these units excellent reliability and requires very little maintenance. The crushers are designed with built-in tramp relief that allows for the passing of uncrushable objects while remaining in continuous operation and returning to the
Dual roll crushers, how they function - Mine Engineer.Com 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 ... Photo of a small scale roll crusher, with a capacity if 1/2 ton/ hour
(A) Maximum feed size determines the required roll diameter (B) For hard material's crushing, the reduction ratio should not exceed 4 (C) Both the rolls run necessarily at the same speed (D) Reduction ratio and differential roll speed affect production rate & energy consumed per unit of surface produced
Jan 12, 2016 Therefore, if minimum production of fines is desirable, it is logical that the heavy end of the 7:1 reduction should be handled in the latter machine. Generally, for such a case, the split would be about 3:1 to the standard machine, and 4:1 to the fine reduction crusher. Screening Crusher Feed
Generally, every crusher machine is not the same, here are several common crusher size reduction ratio: The impact crusher size reduction ratio is 20 to 1. The vertical shaft impact crusher size reduction ratio is 4-8 to 1. The vertical roller mill size reduction ratio is 2-2.5 to 1. The hammer crusher size reduction ratio is 20 to 1
Maximum Diameter of Rock Gripped in Crushing Rolls Relative to Roll Diameter Unless very large diameter rolls are used, the angle of nip limits the reduction ratio of the crusher, and since reduction ratios greater than 4:1 are rare, a flowsheet may require coarse crushing rolls to be followed by fine rolls
Mar 28, 2021 Total reduction ratio. Source: metso. Crushing is done in three, or four stages while grinding is done in one, or three stages. If you don’t have many stages as shown on the app put 1 in the stages that you are not using. Calculate the total reduction ratio of a milling circuit by multiplying the reduction ratios of every stage
