50 micrometers ( m) or smaller by grinding, using smooth rolls, media mills, autogenous mills, hammer mills, or jet mills. The ground material then is classified by wet screening, dry screening, or air classification. At some plants, after initial crushing and screening, a portion of the sand may be diverted to construction sand use.
Particle size reduction, screening and size analysis Objective This laboratory examines the particle size reduction of silica sand using manual and automatic grinding methods and the subsequent separation and size analysis of the obtained polydisperse powders. The particle size of the powder samples will be determined using sedimentation and image

A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().
