The coarser milling equipment — such as roller mills, jaw crushers, impactors, and pulverizers — can handle starting sizes as large as 2 feet by 2 feet and deliver particles as small as 44 microns. Particle size control is less precise with these methods, so final particle size ranges are often quite wide.
