The P-Trak (TSI Inc.), a portable condensation particle counter with a nominal size range of 0.015 µmto1µm and an upper concentration level of 5 × 105 particles/cm3,was added to the study for one process. This instrument provided temporal particle number concentration data and allowed us to map total particle numbers in the vicinity of the ...
For a pellet feed manufacturing plant, the grinding is the second largest energy consumption process. Hence, the grinding process is lot more critical in terms of both animal performance and feed mill productivity. There are two types of machines used for particle size reduction-Hammer mill and Roller mill. Most of the feed mills uses hammer mills.

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 ().
The distance between the discs can be adjusted to allow for more or less grinding which changes the final particle size. The number, depth, and shape of the grinding teeth can also be varied to change the grinding results. This type of grinding mill is commonly used for reducing polyethylene to a powder for the rotational molding industry.
