ABSTRACT:
A conveyor installation for loose material, especially blasting materials for sand-blasting installations, includes on the hall floor, respectively, blast chamber floor at least one longitudinal conveyor (1, 2, 3, 4) and at right angle thereto at its conveyor end in the same plane a cross-conveyor (5). These conveyors (1, 2, 3, 4, 5) operate by the use of conveyor members (27, 28) which are suspended in a pneumatically driven reciprocating frame (19, 24, 33). The frames (19, 24, 33) include lateral girders (20, 21; 31, 32) which are connected by webs (22). The frames run on rollers (11 to 18, 34, 36) which project from boundary profiles (6, 7, 8, 9, 10). The latter delimit laterally the longitudinal conveyors (1, 2, 3, 4). The cross-conveyor (5) includes a boundary profile (35) with rollers (34) only at the side opposite the longitudinal conveyors whereas on the side facing the longitudinal conveyors the rollers (36) are provided at the end faces of the boundary profiles (7, 8, 9 ) of the longitudinal conveyors. For creating a free passage from the longitudinal conveyors to the cross conveyor, the frame girder (31) thereof which faces the longitudinal conveyors, is constructed with a short vertical leg.
