Figure 6.4 is a typical set-up where ores crushed in primary and secondary crushers are further reduced in size by a rough roll crusher in an open circuit followed by finer size reduction in a closed circuit by a roll crusher. Such circuits are chosen as the feed size to standard roll crushers normally does not exceed 50 mm

Apr 24, 2015 4. ROLL CRUSHER Roll crushers are used for producing additional reductions in the sizes of stone after the output of a quarry has been subjected to one or more stages of prior crushing. 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

Sep 15, 2014 A twin-roll crusher is selected, like those given in the Roll Crusher capacity Table above, to serve as the reduction crusher. The smallest, 24 x 16 roll crusher shown in the Roll Crusher capacity Table above has enough capacity with a setting of 1 in. but the maximum size feed will be too large, that is, the stage of reduction is not large enough

Remember back in Section 6.1, we talked about the mean of a random variable as an expected value. We can do the same here and easily derive a formula for the mean of a binomial random variable, rather than using the definition. Just as we did in the previous two examples, we multiply the probability of
