Rice Milling 3.3 Multiple pass rice milling Commercial Mill The milling process in larger commercial mills combines a number of operations that produces higher quality and higher yields of white rice from paddy or rough rice. The process involves 1. Pre-cleaning the paddy prior to milling 2. Removing the husk or outer layer from the paddy 3.
Hollow or solid concrete masonry units used in gravity retaining walls should meet the requirements of ASTM C 90 ref. 2 and preferably have an oven-dry density of 125 lbft 2002 kgm or more. Cores of hollow units are typically filled to increase the weight of the wall. The fill should be granular in areas subject to freezing.
Milling is a crucial step in post-production of rice. The basic objective of a rice milling system is to remove the husk and the bran layers, and produce an edible, white rice kernel that is sufficiently milled and free of impurities. Depending on the requirements of the customer, the rice should have a minimum number of broken kernels.

Floor screeds. A floor screed is usually a cementitious material made from a 13 or 14.5 ratio of cement to sharp sand. It may be applied onto either a solid in-situ concrete ground floor slab or onto a precast concrete floor unit. There are many proprietary screeds on the market and information about these can be obtained from the manufacturer.
