摘要:
The invention relates to a granular melamine, wherein the D99 lies between 300µm and 1800µm. The invention further relates to a process for compacting melamine comprising: - a roll pressing step wherein a melamine powder is pressed into compacted melamine; - a crushing step wherein the compacted melamine is crushed into granular melamine; - a coarse screening step to which the granular melamine is supplied, wherein particles greater than a desired particle size are separated from the granular melamine, wherein the coarse screening step is carried out in such a fashion that the granular melamine has a D99 lying between 300µm and 1800µm.
