The transportable centrifuge for projection materials is provided with a special endless belt (15) passing on rollers (14 and 26), and with a rotary plate (2) having a lining (3) on each outer surface. The special belt (15) entwines partially the lining (3), and the projection material (7) is speeded up between the grooves of the lining (3) and of the special belt (15). The lining (3) with longitudinal grooves may be replaced rapidly by another lining with transversal cuts of different grooves, and the inner surface of the belt (15) is provided with a profile parallel to the peripheral direction wherein the outer surface of the rollers (14, 26) is in mesh to drive the special belt (15) owing to their corresponding profile. |
