For blake-type crusher, its feeding area is fixed while discharging area is changeable. The,NPTEL,Blake jaw crusher Gyratory crusher Rod mill No, the answer is incorrect. Score: 0 Accepted Answers: Blake jaw crusher In a three stage crushing circuit having same reduction ratio of 5 in each stage, if the average ROM feed size entering the first crusher is 400 mm,find out the product size of the second crusher in the circuit. 2000 12 16 3.2TECHNICAL NOTES 5 CRUSHERS - mineraltech,Jaw crushers are operated to produce a size reduction ratio between 4:1 and 9:1. Gyratory crushers can produce size reduction ratios over a somewhat larger range of 3:1 to 10:1. The primary operating variable available on a crusher is the set and on jaw and gyratory the open-side set (OSS) is specified. This reflects the fact that considerable,3 size reduction - SlideShare,21-09-2019· PROBLEM 2.1 A material is crushed in a Blake jaw crusher such that the average size of particle is reduced from 50 mm to 10 mm, with the consumption of energy of 13.0 kW/(kg/s). What will be the consumption of energy needed to crush the same material of average size 75 mm to average size of 25 mm: (a) assuming Rittinger’s Law applies, (b) assumingMechanical Operation,In Blake jaw crusher, the angle between the jaws is usually. a) 5 0 b) 15 0 c) 30 0, 75. Under otherwise uniform conditions, size reduction ratio obtained in a ball mill . a) is greater than that obtained in a jaw crusher. b) is smaller than that obtained in a jaw crusher.Tips to maximize crushing efficiency - Pit & Quarry : Pit,,13-05-2019· Additionally, jaw crusher feed should be pre-screened using a grizzly screen prior to crushing to remove material finer than the closed-side setting. Setting jaw crushers. 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.
