FIELD: equipment for grinding materials of natural shelf. SUBSTANCE: drum consists of cylindrical body connected on side of ends by flange with section in the form of angle and circular flange. Installed on drum surface are at least three auxiliary circular shells with uniformly spaced hole groups. Circular supporting members are uniformly spaced between circular shells. Uniformly spaced on drum surface over circumference are stiffening ribs. Flanges are connected by means of angles to drum cylindrical body, with ends of circular shells, and partially with ends of longitudinal members. Drum is made with rectangular windows and holes for installation of hatches. Drum also has auxiliary body with two holes whose location, diameter and amount coincide with mating holes made in end of drum main body. Auxiliary body is attached to drum body by means of self-locking threaded members with conical threaded profile. EFFECT: higher efficiency of drum operation. 3 dwg
