The by-products in rice milling are rice hull, rice germ and bran layers, and fine brokens. V. MILLING SYSTEMS A rice milling system can be a simple one or two step process, or a multi stage process. In a one step milling process, husk and bran removal are done in one pass and milled or white rice is produced directly out of paddy.

An aluminum block of length 50 mm and width 70 mm is being milled using a slab milling cutter with 50 mm diameter. The feed of the table is 15 mm/min. The milling cutter rotates at 60 RPM in clockwise direction and width of cut is equal to the width of the workpiece. Draw a neat sketchof the milling operation describing aboveconditions. The

process must be illustrated clearly in a yearly, monthly, daily, and hourly rate. The capacity not only determines the mill equipment size, but also dictates how to operate the mill, whether continuous or batch operation is required, and whether the process can be performed in-house or if a tolling service is a better option.
