EXPERIMENT 1: SIZE REDUCTION AND SOLID SCREENING TITLE: Grinding of rice OBJECTIVE: To calculate the energy needed for grinding of rice. INTRODUCTION Size reduction always can be related to crushing and grinding. The purpose of grinding is to make large solid materials into smaller sizes. As we can see, raw materials from the farm are big ones and need to be processed in order to ease .
Work Index is calculated in order to get the power required to reduce a material with a given 80% passing size to a specific product with 80% passing size. Grindability refers to the ability which materials can be comminuted, and the grindability data from the test are used to determine crushing and grinding .
