Gypsum Grinding Mill Plant

Process Introduction

The gypsum powder production plant processes natural dihydrate gypsum ore (gypsum) or industrial by-product gypsum (such as desulphurisation gypsum, phosphogypsum, etc.) through grinding in mills. This material is then heated and calcined at a specific temperature, causing the dihydrate gypsum to undergo dehydration and decomposition. This yields β-hemihydrate gypsum (CaSO₄·1/2H₂O), which constitutes the primary component of the product—building gypsum.

Process Description

1. Gypsum Crusher:  Raw gypsum is first crushed into smaller particles by a crusher to facilitate the grinding process.

2. Grinding Mill: The crushed gypsum is then sent to a grinding mill where it is ground into a fine powder. Common types of grinding mills for gypsum include ball mills, Raymond mills, vertical roller mills, and ultrafine mills.

3. Classifier: A classifier is often used to control the particle size distribution of the ground gypsum powder. It separates the fine particles from the coarse ones and ensures a consistent product quality.

4. Dust Collector: A dust collector is essential to collect and remove airborne dust generated during the grinding process, ensuring a clean and safe working environment.

5. Packaging Machine: Once the gypsum is ground to the desired fineness, it is packaged using a packaging machine for storage or transportation.

Process Advantages
