Dust Control on Andesite Stone Processing Industry

Abstract

The research aims to make efforts to control dust generated in the processing industry of stones. This industrial location in the village Hargomulyo, Kokap, Kulon Progo, Yogyakarta. This study background that the andesite stroke processing industry, especially in the stone crusher tool with the flow of exhaust gas, dust arise in large numbers. Their media scattered wind the wind-borne dust is so dispersed into the environment around the site and it is dangerous to public health. It is necessary to control the spread of dust. The research was conducted in the laboratory and simulation using dust extraction equipment fogging method. Optimized variable is the diameter of the nozzle, while the others held constant magnitude replications, then the results are averaged. After doing research, the research data obtained that the optimum conditions mass of dust captured by the mist that is the nozzle diameter of 1.50 mm with an average mass of dust that can be captured by the mist that is 13327.33 g and an average efficiency value 70.69 %. Equation of a line that states the relationship between the variable diameter of the nozzle by the symbol X Masses of dust captured by the mist by the symbol Yie Y = 392.X3 + 3969,9X2 + 10090X +5542.4 the percent error 0.77%, while the equation stating the relationship between variables within the sprayer to the tools by the symbol X with the value of efficiency by the symbol Yie Y = 1, 2333X3 -13,528X2 + 40,199X + 33.878 with percent average error of 0.54%. An increase in the efficiency of dust extraction tool is then expected spread of dust into the environment as a result of the processing of andesite can be minimized so that the air quality around the site will be maintained well.
