HTPB based composite Solid propellants are the source of power for the propulsion of rockets and missiles. Since composite solid rocket propellants, used in rockets and missiles is the fastest degrading component of the complete system, shelf life of the system is mainly governed by the life of the propellants. During storage and transportation, the propellant grains are subjected to various co...

Dried sphagnum moss was ground using a pin mill and hammer under various operating conditions, i.e., changes in the rotor frequency feed rate. The specific energy consumption of size reduction recorded. powder characterized by median particle size, width distribution (span), loose tapped bulk densities, Hausner ratio. Pin milling used less for than milling, especially when target below 100 μm. ...

Cereal grains are the primary energy source in swine diets. Therefore, not only must producers be concerned about the composition of the grain, but also how it is processed so the pig can fully utilize the nutrients. Because feed represents 65 to 75 percent of overall production costs in a swine operation, improving the efficiency of feed utilization will have a tremendous impact on the cost of...
