The quality of every product, or material analysis, depends on the quality of the sample preparation. It is therefore extremely important to consider all 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.
