01-04-2019· Ideally, the reduction ratio of a jaw crusher should be 6:1. 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 per cent versus the discharge size that passes 80 per cent.Crushing of coal and calculation of size reduction efficiency.,25-02-2015· Crushing efficiency • Generally the efficiency of crusher has been calculated from the Power point of view. • As per a data in US, 1 % of the energy generated is used up for Size reduction Processes • The literature in the areaThe energy efficiency of ball milling in comminution,,01-11-2002· In terms of this concept, the energy efficiency of the tumbling mill is as low as 1%, or less. For example, Lowrison (1974) reported that for a ball mill, the theoretical energy for size reduction (the free energy of the new surface produced during grinding) is 0.6% of the total energy supplied to the mill setup.Optimization of Comminution Circuit Throughput and Product,,01-07-2005· Abstract. The goal of this project was to improve energy efficiency of industrial crushing and grinding operations (comminution). Mathematical models of the comminution process were used to study methods for optimizing the product size distribution, so that the amount of excessively fine material produced could be minimized.USING THE SMC TEST® TO PREDICT COMMINUTION CIRCUIT PERFORMANCE,the ball mill is less energy efficient than a crusher and has to input more energy to do the same amount of size reduction). Hence from equation 7, to crush to the ball mill circuit feed size (x. 2) in open circuit requires specific energy equivalent to: f x f x 2. 1 W c ic. 1.19* 4 2Breaking down energy consumption in industrial grinding mills,Grinding mills are infamous for their extremely low energy efficiency. It is generally accepted that the energy required to produce new mineral surfaces is
