ABSTRACT Research on analysis of bulk solids separation pneumatically had not been properly in Indonesia and, therefore, this research was considered an earlier investigation on the material separation with pneumatic blowing method. The investigation was carried out using a square tube with 300 cm, long, 35 cm wide, and 50 cm high. The objectives of the research were: (1) to develop a mathematical equation on solids hurling distance with dimensional analysis method, (2) to study variables giving influences to solids hurling distance, (3) to validate model, comparing output of model to output of real solids. /The research used dimensional analysis to develop a predictive equation on solids hurling distance. It used a model made of circular wood solids with varied diameters. The investigation was done by varying the heights of material fall, distance of pneumatic blow, air velocity, angles of blower and hopper used to predict agricultural materials i.e. rice, small green pea, soybean and corn. The material test and agricultural variables was analyzed with multiple regression. The findings of the research showed that coefficient determination value of model was 0,903
