Abstract (en)
[origin: EP0404133A2] A vibrating grinder (1) contains several exhaust openings (37) on the underside (16) of its grinding shoe (3). The exhaust openings (37) are arranged at the edge of the grinding shoe (3). So that the grinding dust can also be effectively removed in the centre area between the rows of exhaust openings (37), a further opening (42) is located approximately in the centre of the grinding shoe (3), which opening (42) is vented via a channel and is not connected to the fan for the exhaust openings. <IMAGE>
