YGM160 Ryamond Mill For Gypsum Production 8-16tph

The YGM160 Raymond Mill Plant for gypsum processing follows a streamlined workflow that includes ​​material pre-drying, feeding, grinding, classification, powder collection, and dust control​​. Here's how it works:

1. ​​Raw Material Preparation

    • A jaw crusher reduces gypsum lumps to ≤30mm—small enough for efficient drying and grinding. Gypsum’s softness means minimal crushing force is needed, reducing energy use and wear.

    • Uniform particle size ensures even drying in the next stage, avoiding “wet cores” that cause caking during grinding.

​​2. Integrated Pre-Drying Process​​​

    • Crushed gypsum particles move through the rotary dryer (heated by natural gas, diesel, or biomass), where hot air circulates to lower moisture to 2-3%. The dryer’s inclined design ensures slow, even movement—no over-drying or under-drying.

    • Gypsum begins to lose water of crystallization at temperatures above 150°C; the rotary dryer stays below this threshold, preserving gypsum’s chemical properties (critical for cement retarders or construction use).

​​3.Precision Grinding Operation

    • A frequency-adjustable vibrating feeder transports dried gypsum into the YGM160 mill’s grinding chamber.Inside the grinding chamber, 4 high-chromium steel rollers rotate against a fixed grinding ring. Gypsum is crushed and ground via gentle pressure (not impact) to avoid overheating. A high-pressure spring system enhances roller contact, ensuring thorough grinding even for denser gypsum varieties.

    • The Raymond mill YGM160’s optimized chamber design increases airflow, carrying ground particles to the classifier quickly and reducing grinding time—supporting 8-16 TPH output for gypsum.

​​4. ​​Product Collection and Packaging

    • Captures 95% of the classified gypsum powder using centrifugal force. Its smooth, anti-stick inner lining prevents gypsum from adhering to walls (a common issue with sticky, high-moisture gypsum), maximizing recovery.

    • A pulse-jet bag filter traps residual dust, meeting EPA and CE environmental standards. This eliminates air pollution and ensures a clean workspace—ideal for plants near urban areas.

    •Collected gypsum powder is discharged into a storage silo via a screw conveyor. It can then be packaged into 25kg bags (for small sales) or loaded into bulk trucks (for construction projects). The entire process is automated, reducing manual labor and contamination risks.
