Investing in a raw gypsum (dihydrate gypsum, CaSO₄·2H₂O) grinding and processing production line, the selection of the grinding mill directly determines the output, energy consumption, and key indicators (standard consistency, setting time) of the final product (building gypsum powder). The core requirement is to efficiently complete the two major processes of “grinding” and “calcination dehydration.”
Top Recommendation: Integrated Calcination Grinding Mill For large-scale production (e.g., annual output exceeding 100,000 tons), the vertical mill is the preferred solution. It integrates crushing, grinding, drying, calcination, and classification within a single unit.
Core Advantages:
Extremely streamlined process with high thermal efficiency: Simultaneous grinding and calcination eliminates the need for separate fluidized beds, rotary kilns, and subsequent grinding equipment. High heat exchange efficiency reduces overall energy consumption by 20%-30% compared to traditional “calcination-first, grinding-later” processes.
Superior Product Activity: Rapid calcination in suspension ensures uniform heating. The resulting building gypsum powder exhibits low standard consistency water demand, high strength, stable setting time, and premium quality.
Low Investment and Operating Costs: Compact system footprint, minimal space requirements, high automation levels, and reduced staffing needs.
