Abstract (en)
[origin: EP0761310A1] The grinding and sifting process involves passing the material through a coolant and grinding it in a mill (8). The ground material is then taken to a sieve (14) designed to keep out the ambient air, and in particular the moisture in it. This is done in a closed process. The sieve is supplied with the same gas coolant as the mill so that losses from the sieve gas circuit can easily be made good. The upper portion left on the sieve is fed back to the mill. There is a line on the output side of the mill which leads back to the input side.
