For the cement quality of a roller press finish‑grinding system, studies show that for a standard type cement compared to VRM or ball mill, no differences could be observed. Only for fine cement types (>4500 Blaine), requiring high early strengths, did the roller press finish‑grinding system achieve slightly lower strength performances.
