A device for working at hard material. The device comprises a container (4) with a sieve (6) where abrasive is sieved under a liquid surface (7). Liquid is supplied to the suction conduit (13) of a low pressure pump (8) for creation of a slurry which is pumped to a pressure vessel (10). This pressure vessel is then pressurized for the feeding of abrasive to a high pressure conduit (2) where the the abrasive is mixed with high pressure liquid which is supplied to a nozzle (3) for the creation of a jet stream. |
