The utility model discloses a friction tester of dense granule bodies, which is characterized in that a guide rail translation stage and a granule matter containing groove are arranged on a base together, and the guide rail translation stage can do linear reciprocating movement on the base. A pedestal is supported on the guide rail translation stage and can move along with the guide rail translation stage, and a horizontal measuring arm is fixedly connected with a vertical measuring arm through the front end of the horizontal measuring arm. A torque sensor is fixedly arranged on the pedestal, and the top end of the torque sensor is connected with the middle part of the horizontal measuring arm in an articulated structure. A pull pressure sensor is vertically arranged at the tail end of the horizontal measuring arm, and the bottom end of the pull pressure sensor is butted at the surface of the pedestal. A test board is connected with the bottom end of the vertical measuring arm, is arranged in the granule matter containing groove, and can be contacted with granule bodies in the groove. The friction tester of dense granule bodies is used for measuring the frictional characteristics of granule matters and the surface.
