Development of Two Pellet Die Organic Fertilizer Compression Machine

This research aims to study a development of two pellet die organic fertilizer compression machine. The pellet system consisted of 4 rollers which divided into 2 rollers of each side using electrical motor 3 hp, transmit to gear of walking tractor. A foreword and reverse gear are used for transmitting power into shaft pellet compression. Diameter of cylinder compression was 254.00 mm, with the hole size on the pellet die is 5.0 mm, the diameter of rollers was 70 mm, the length was 130 mm. at the speed of shaft pellet compression was 250 rpm. Speed of shaft feeder was 225 rpm. The average bulk density of pellet is 745.40 kg m-3. The average compression capacity of the machine was 504.43 kg/hr. The percentage of durability of pellet and broken pellet were about 91.73% and 8.27% respectively
