Minimization of fines generation in size reduction of

Minimization of fines generation in size reduction of coals by impact crusher Taguchi's design of experiment was used to minimize the number of experiments done to obtain meaningful results It was concluded from the experiments that among process parameters RPM has a more prominent effect on generation of fines compared to feed rate Get price



Although excessive fines may have to be "scalped" from the feed (more common in jaw crushing circuits) the trend in large-capacity plants with gyratory crushers is to dispense with grizzlies This reduces capital cost of the installation and reduces the height from which the ore must fall into the crusher thus minimizing damage to the spider Get price
