The effect in this job is better ...
This leads to a narrower size distribution and significantly less slime compared to ball mills. Lower critical speeds of 50 - 65 and coarser product size i.e. 50 mm v . 15 mm results in a lower impact environment but decreased abrasion resistance due to the feed size.
The quality of every product or material analysis depends on the quality of the sample preparation. It is therefore extremely important to consider all the individual milling parameters in order to make an informed choice material properties, feed size and volume of the sample, grinding time and desired final particle size, any abrasion of the grinding parts all these factors are significant.
