<p>In the process, the material to be ground is cooled essentially ahead of a comminuting device (1) in a cooling shaft (2) with a material charging hopper (3) with the aid of a very low temperature cooling gas. The cooling gas is guided via lines (9, 11, 13) in a circuit through the cooling shaft (2) and through a reservoir (6), connected downstream of the comminuting device (1), with filter (8) and a fresh cooling gas is injected into the circuit via an atomising device (15). In order to generate a conveying gas stream in the communiting device (1), a conveying gas stream is branched off from the circuit and directed via a line (12) to the comminuting device (1). In order to compensate a change in the material structure occurring during the comminuting process or in order to manufacture a product, such as for example seasoning mixtures, which is only complete in a mixture state, it is provided to add corresponding additives to the material to be ground before the comminuting process and/or during the comminuting process. For this purpose, a corresponding admeasuring device (18, 19) for the additives can be assigned to the cooling shaft (2) and/or the comminuting device (1). <IMAGE></p> |
