A mobile grinder for processing gypsum is a versatile and efficient solution for grinding gypsum rocks or waste materials into fine powder for various applications, such as construction (plaster, drywall), agriculture (soil conditioner), or industrial uses. Here’s a breakdown of key considerations:
1. Types of Mobile Grinders for Gypsum
– Mobile Jaw Crusher + Hammer Mill Combo: Crushes large gypsum rocks into smaller pieces before fine grinding.
– Mobile Impact Crusher: Suitable for medium-hardness gypsum, producing uniform particle sizes.
– Mobile Ball Mill or Raymond Mill: For ultra-fine grinding of processed gypsum into powder (for plaster or cement additives).
– Portable Hammer Mill: Efficient for coarse to medium grinding of gypsum.
2. Key Features to Consider
– Mobility: Track-mounted or wheeled units for easy relocation.
– Feed Size & Capacity: Match the grinder to your raw gypsum size (e.g., lumps vs. crushed fragments).
– Output Fineness: Adjustable settings for different applications (e.g., 20–100 mesh for plaster, 200+ mesh for high-grade products).
– Dust Control: Gypsum dust can be hazardous; opt for grinders with integrated bag filters or wet suppression systems.
– Power Source: Diesel, electric, or hybrid options depending on site conditions.
3. Top Manufacturers & Models
– Sandvik Mobile Crushers & Screeners – Track-mounted impact crushers.
– Metso Lokotrack® LT Series – Mobile jaw/impact crushers.
– Kleemann Mobirex MR Series – For high-performance gypsum grinding.
– Williams Patent Crusher – Portable hammer mills for finer grinding.
4. Applications of Processed Gypsum
– Construction: Plasterboard, drywall, cement retarder.
– Agriculture: Soil amendment to improve water retention.

5. Cost Considerations
– Small portable grinders: $50,000–$150,000 USD.
– High-capacity mobile units: $200,000–$500,000+ USD.
– Operating costs depend on fuel/power consumption and maintenance needs.
6. Maintenance Tips
– Regularly check hammers/liners for wear (gypsum is abrasive but softer than minerals like quartz).
– Clean dust collection systems frequently to
