Agricultural turner has become an essential task in livestock farms for environmental improvement such as mushroom culture medium mixing, as well as odor and gas generation reduction in livestock farms. Although various shapes of turner are sold, the reliability of the product is insufficient because the turning performance has not been suggested. The purpose of this study is to analyze and compare the turning performance through particle behavior analysis using five commercially available turner blades. The analytical conditions were filled with particles A and B 750 kg with a diameter of 9 mm in a ratio of 1: 1 in the upper and lower layers of the 0.6 m3 box and analyzed with a turning blade rotation speed of 100 RPM, forward and backward movement speed of 0.1 m / s, and 300 steps. After turning, Six boxes were created and the ratio of the particles in the box was calculated, and the turning rate was analyzed through the C.V value. As a result, According to Table 5, C.V of E blade was the best with 22.2, 30.9, C.V of D blade was the worst with 98.3, 52.2. The turning rate was the best when the particles on the edge were gathered in the center and turned over like E blade.
