This investigation was carried out to develop and manufacture small animal feed mixing machine. Feed mixing machines are used in feed mills for the mixing of feed ingredients and premixes. The mixing machine is essential part in the feed manufacture, with accurate mixing being the key to good feed manufacture. The machine is small and works by very small power if compared with other machines. The goal of this experiment was to determine the optimum mixing duration at which the highest degree of

Experimental and designing studies were confined to determine the effect of mixing duration at constant speed of mixing drum, 228 rpm on coefficient of variation, degree of mixing (homogeneity), machine productivity, specific energy and mixing cost and the effect of moisture content of feed mixture on Pelleting efficiency. The machine was experimented and evaluated using four different mixing durations (5, 10, 15 and 20 minutes) and using different moisture contents of feed mixture (25, 28 and 31%). Results indicated that the mixer shaft was designed at a diameter of 20mm. The highest value of the performance parameters of the mixing machine and the optimum mixing duration was 5 minutes. The suitable moisture content of feed mixture for the following process which is pelleting process was 28%.
