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 ().

particle size is a fixed value, only dependent on the effi-ciency of the equipment, milling time, density of GM, and mill base (McDowell, 2006). Various studies were conducted to analyze the influence of materials of GM of different specific weights, sizes of GM, stirred tip speeds, milling times, and solid concentrations on particle size

A fluid bed jet mill, due to the classifying rotor, will consistently produce in-spec product regardless of fluctuations in the raw feed particle sizes. 11. Are jet mills for continuous or batch operation? Typically, jet milling systems are designed for continuous operation. However, pancake and loop lab units can be operated in a batch mode. 12.

In keeping with the notion of consistency, milling should occur at a uniform temperature consistent with efficient particle size reduction, and which will not harm the product. Biological samples, particularly animal tissues, can be susceptible to heat damage. "We use several ways to control temperature," Stummer says.

Pin mill configuration. In a pin mill, the particle size is controlled by three parameters: Feed rate, rotor speed and airflow. Varying these parameters will have the following effects: Increasing the feed rate will result in a coarser particle size while reducing the feed rate will have the opposite effect.
