Maschinenfabrik K 246 ppern Der Spezialist f 252 r
High-pressure grinding rollers (HPGR) During the high-pressure comminution process, rather than being crushed between the roller surfaces, individual grains or particles are in effect compacted to a dense flake through exposure to relatively high pressures. Following de-agglomeration, the flake normally shows a substantial amount of completed or incipient cracking emanating from the particle ...
