The aim of this research is to study with the limited pollution from Robusta coffee grinding process. The pollution behavior is used to design the limited pollution unit by consists of the dry and wet limited pollution unit. By the dry limited pollution unit tangential air cyclone was regarded. In term of the wet limited pollution unit has to 3 chambers by semi-wet chamber wet storage chamber and overflow chamber. However the efficiency of the limited pollution unit another pollution and economic engineering were determined. The results of research found that the rate of coffee grinding was 243 kg/hr and the mass of pollution was 37.3 to 41.9%. By the motion of pollution was projectile with the speed approximate 14.7 m/s and the distance of pollution was 5.25 m. Based on the dry limited pollution unit designed the efficiency of limited pollution just 79.25%. While the wet limited pollution unit can be limited to 100%. The tendency of pH of water in the wet limited pollution unit was increased to pH9 under past in 24 hours. In case of the break-even point must be grinding with 1400473 kilograms and payback period will occur at 2.1905 years.
