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 or by animals (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

The mill performance is governed by a number of operating variables including mill stirrer speed, feed particle size, solids content and slurry rheology. A study was conducted to assess effects of mill speed, media size and density, and slurry density on the Stress Intensity (SI) in a VXPmill and thereby the relationship to mill performance.

Bottom line: an increase in operational ef-ficiency from 89.2% to 93%; variable cost reduction of 5%; 38,000 admt production over the budgeted amount; controls in au-tomatic mode 95% of the time. OPP A "BIG DIFFERENCE" A 3.8% boost in operational efficiency may not sound like much. But in a mill designed

The operator gently pushes the mill frame through the log to affect the first cut. Carriage movement through the log requires about 10 lbs. pressure as you are letting the blade do most of the work. A simple hand movement swings and locks the cutting unit into a vertical position, which is then pulled back down the log.
