Rice straw has a very high silica content (8 to 14%) com-pared with alfalfa hay (1 to 2%). Silica is indigestible and decreases digestibility of the feed. This is particularly true in the rice leaves, which contain the highest levels of silica. This high silica level combined with other mineral compounds produces an average ash content of 17% for rice

Abstract Rice husk is a form of agricultural biomass that provides an abundant silicon dioxides source. This study use rice husk ash as a material to prepare silica. Silica powder has been synthesized by the refluxing of rice husk ash with HCl 1,2 and 3 M at different time (60 and 120 min.) and subsequently adjusting the pH using 1 M. NaOH.

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, working animal, wind or water. Today they are usually powered by electricity. The grinding of solid materials occurs

Rice husk (RH) is an inexpensive byproduct of rice processing and is separated from rice grain during the rice milling process. It is reported that, for every ton of rice produced, about 0.23 tons of RH is formed . Rice milling is one of the most important industries in countries such as China, India, Indonesia, Malaysia, and Bangladesh . The incineration of RH is discouraged, which in turn produces ash, fumes, and toxic
