Energy considerations in compressive and impact crushing

01/08/2008 Other similar models for energy consumption, referred to as Kick’s and Rittinger’s equations are shown in Eqs.,. (1) W Bond = C Bond × 1 p 80-1 f 80 (2) W Kick =-C Kick ln p 80 f 80 (3) W Rittinger = C Ritt × 1 p 80-1 f 80. Here, W is the energy consumption per tonne of material crushed, C Bond is the so-called work index of the rock, obtained in a test.

ANALYSIS OF ENERGY CONSUMPTION OF CRUSHING PROCESSES

analysis of the results shows that taking into account energy consumption, it is better to use two-stage crushing process. For given materials energy consumption in the two-stage crushing process was reduced by 30%. Key words: rock crushing, jaw crusher, crushing efficiency, two stage crushing process 1. INTRODUCTION The main aim of processing rock raw materials is to prepare and process the

The Effects of Blasting on Crushing and Grinding

Energy Consumption in Crushing and Grinding The energy input to size ore fragments is large. Overall reduction, performed in a series of stages may be from an eighty percent feed size passing of 40 cm (15.8 inches) to a final product size of 270 to 325 mesh (.053 to .045 mm). A lot of energy is expended to accomplish this, and

Rock Crushing Theory and Formula using Kick & Rittinger's

It is the purpose of this paper to record and interpret a series of experiments made for the purpose of studying the consumption of energy in the crushing or fracturing of rock particles both coarse and fine. At the start, the expectation was to determine constants according to the Rittinger theory for several rocks, whereby it would be possible to calculate absolute crushing efficiencies of machines crushing

The obtained results were compared to the energy associated to rock crushing by three-angular tips shape and smooth plates. The three domestic rocks: Morawica limestone, Mucharz sandstone and

Rock Crushing Theory and Formula using Kick &

This energy as foot-pounds, or as horsepower-hours, can be compared with the surface produced as shown by the crushing-surface diagram of the screen analyses of initial and final products of the operation; and it can likewise be compared with the energy units (E. U.) of Stadler, as shown by mechanical-value diagrams similar to Fig. 9. By crushing the same amount of rock from coarse to

Crushing Energy & Work of Crushing Machines

“The work done in crushing is proportional to the surface exposed by the opera­tion, or better expressed for this purpose, the work done on a given mass of rock is proportional to the reciprocal of the diameter of the final product, assuming that all the mass has been reduced to one exact size, which is only theoretically possible.”— A. O. Gates: Engineering and Mining Journal, vol. xcv
