PROBLEM TO BE SOLVED: To provide a horizontal cylindrical sand mill which can improve an actual performance rate of grain shape decision of products. SOLUTION: The horizontal cylindrical sand mill is equipped with a drum 1 which is closed at one end of a horizontal cylindrical or nearly cylindrical drum body 1a rotated around an axis by an end wall 1b having a supply port 2 and at the other end by an end wall 1c having an outlet 3, respectively, and is internally compartmentalized to two chambers continuous in a longitudinal direction by a partition 1d having a through-hole. The chamber on the supply port side is constructed as a crushing chamber 7 into which rods 6 or large-diameter balls are charged and the chamber on the outlet side is constructed as a grain shape regulating chamber 10 into which the small-diameter balls 9 are charged. Also, the ratio of the internal diameter of the grain shape regulating chamber 10 to the internal diameter of the crushing chamber 7 is specified to 0.65 to <1.0. COPYRIGHT: (C)2004,JPO
