For these kinetics tests, samples were ground in the stirred mill up to 32 min, and sub-samples were collected following an exponential time series starting at 0.5 min. When the desired grind time was reached, the mill shaft was halted, and a plastic syringe was used to extract slurry from various radial positions and depths inside the vessel.

Ball mills are the most commonly used piece of equipment for milling. However, vibratory mills, attrition mills, and fluid energy mills also are used. Crushing and grinding typically are dry processes; milling may be a wet or dry process. In wet milling, water or alcohol commonly is used as the milling liquid.
The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6. Rod mills accept feed up to about 50 mm (2 in.) and produce a product in the size range of 3000 to 270 mm (–4 to –35 mesh).

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 ().

Glass cullet is fed into a ball mill for grinding. Very fine glass powder ranging between 100 and 500 microns is mixed with a foaming agent and heated to the foaming temperature between 700 and 900°C. Figure 5.19 shows the process flow diagram from the waste glass “cullet” to the foam glass manufacture of a typical foam glass product.
Milling is done using a cylindrical milling tool mounted in a milling tool holder that is then mounted in the tool spindle on the machine. End Mills End mills are the most common milling cutters. End mills are available in a wide variety of lengths, diameters, and types. A square end mill is used for most general milling applications.
