Due to the high hygroscopicity, caking property, thermal melting and decomposition of mono‑ammonium phosphate , an open‑circuit grinding mill must be adopted for pulverization. Currently, the open‑circuit Raymond mill is the most technically mature and cost‑effective processing equipment in the industry.

The silicon carbide grinding production line requires multi-stage crushing and multi-stage iron removal. For the conventional 80~400 mesh silicon carbide powder sector, a wear-reinforced Raymond mill is recommended, while for the high-end 400~2500 mesh sector, an ultra-fine vertical roller mill that prevents metal contamination is the preferred choice.

Due to the strong adhesiveness of calcium hydroxide, ordinary grinding mills cannot achieve efficient grinding. A hydrated lime grinding mill with a full-system anti-adhesion design must be used. A complete calcium hydroxide production line mainly consists of a lime slaker, a hydrated lime classifier, a hydrated lime grinding mill, and a water mist dust collector.
