| Abstract | The objective of this research was to apply pozzolan material as a binder replacement with the original binder material and use domestic abrasive material as composite material in the casting process of rice polishing cylinders. In the present, the original binder was imported as calcined magnesite cement that cost an average of 50 million baht per year. This research has selected pozzolan materials which consist of rice husk ash, bagasse ash, and metakaolin to use in the experiment and substitute Calcined Magnesite Cement by 60% using design of experimental with licensed Minitab Release 14. According to the mixture design function which has 10 formulations for compressive strength and tensile strength testing, it found that the optimal formular was rice husk ash : bagasse ash : metakaolin equal to 15: 25 : 60. When used this formular to cast the cylinder and test rice milling, it found that average broken rice percent was reduced to 16.41 and the average wear rate was 3.91 g/hr. While the rice polishing cylinder which used all abroad composite material has average broken rice percent equal to 23.98 and average wear rate equal to 7.02 g/hr. So, the using composite material from pozzolan materials and domestic abrasive material can improve the efficiency of rice milling and quality of rice polishing cylinder. |
