Introduction

1.Gypsum Powder Production Line

Gypsum grinding plant, Gypsum powder manufacturing process, Raymond Mill Gypsum Powder Production Line is a complete set of equipment designed to process natural gypsum (CaSO₄·2H₂O, Dihydrate gypsum) or industrial by-product gypsum (such as FGD gypsum, phosphogypsum) into construction gypsum powder (β-hemihydrate gypsum). Using the Raymond mill (also known as the high pressure roller mill) as the core grinding equipment, gypsum powder production line integrates grinding, classifying, and calcining processes. It is widely used in building materials, chemical engineering, ceramics, medical, and food molding industries.

2.Core Equipment – Raymond Mill

The Raymond mill is the core of gypsum powder production line, offering several advantages:

Compact Structure: It integrates crushing, grinding, classifying, and conveying into one system.

Stable Operation: It features a three-dimensional structure, a small footprint, high system integration, and low energy consumption.

High Fineness: The finished powder fineness is adjustable between 80 and 325 mesh, meeting the requirements of construction gypsum.

Environmentally Friendly: The system operates under negative pressure to prevent dust leakage. Equipped with pulse dust collectors, it complies with stringent environmental protection standards.

3.Applications

The gypsum powder produced by this line is mainly used for:

Building Materials: Plasterboard (drywall), gypsum blocks, plastering gypsum, putty powder.
Molds: Ceramic molds, precision casting molds.
Others: Medical plaster (orthopedic casts), food additives (tofu coagulant), cement retarder.

Production Line Features

Working Principle

1. Coarse crushing stage

Large pieces of gypsum ore (or waste gypsum) are first crushed to about 30 mm or less by a jaw crusher.

2. Conveying and feeding

The crushed material is sent into the storage bin by a bucket elevator, and then evenly and quantitatively fed into the Raymond mill main unit by an electromagnetic vibrating feeder.

3. Main grinding stage

The material is crushed by grinding between the grinding rollers and grinding ring in the Raymond mill main unit.

4. Classification and screening

The ground powder is blown by airflow into the classifier for separation. Qualified fine powder passes through, while unqualified coarse powder falls back into the main unit for regrinding.

5. Collection and finished product

The qualified fine powder enters the cyclone collector (or pulse dust collector) with the airflow to be separated and collected, finally obtaining finished gypsum powder, which can be packaged and stored.
