Apparatus and process for producing particles of granulated material from a molten material, with a perforated plate (2) having nozzles (1) arranged therein, wherein a cutting arrangement with a blade head (4) having at least one blade (3) lies opposite the perforated plate, wherein the apparatus furthermore has a cutting chamber (7) in a housing (6), through which cutting chamber a cooling medium introduced into the cutting chamber (7) from an inflow device (8, 9) flows, wherein, at least in certain portions extensively at least in the region of rotation of the at least one blade, one or more additional feed opening(s) (12, 13) for feeding an additional stream of cooling medium to the cutting chamber is/are provided with such an orientation that this additional cooling medium stream differs from the cooling medium flowing in through the inflow nozzle arrangement (9) at least in one of the following parameters: phase, direction, speed, pressure, temperature, density, throughput and/or composition. |
