Then, the fine particles can pass the screen, and the big particles, which cannot match the required size, become the subject of the grinding again. Although the set up cost of a roller milling is relatively expensive, it consumes less energy than a hammer mill. However, it is less used than a hammer mill in a dry mill industry.
Choice of particle size analysis technique is a function of the goals of the analysis. Many of the particles encountered in mining are characterized by sieves (classifiers). These are screens with a known opening (mesh) size. Particles smaller than that mesh size will pass through the screen .
