Gypsum Grinding Mill Plant Share

Gypsum grinding production line is a complete equipment system specifically designed to process natural gypsum ore or industrial by-product gypsum into gypsum powder of varying fineness. As a crucial raw material processing equipment for industries such as construction, medical care, and food, modern gypsum grinding production lines integrate crushing, grinding, grading, calcining, and conveying, achieving automated and intelligent gypsum powder processing.

1. Gypsum Grinding Production Line Core Equipment

1.1 Crushing System

A jaw crusher or hammer crusher is used for primary crushing of the raw material, reducing bulky gypsum ore to particles ≤30mm.

Technical Features:

• Feed Particle Size: ≤400mm

• Discharge Particle Size: ≤30mm

• Processing Capacity: 10-100t/h

1.2 Grinding System

Core equipment includes Raymond mills, vertical mills, and ball mills, with different types selected based on the required fineness of the finished product.

1.3 Classification System

A high-efficiency turbine classifier is used to achieve precise particle size control and ensure uniformity in the finished gypsum powder. 

1.4 Classification Accuracy:

• Ordinary gypsum powder: ±5μm

• High-precision gypsum powder: ±2μm

2. Gypsum Powder Grinding Production Process

• Raw Material Pretreatment: Gypsum ore → Crushing → Screening → Storage

• Grinding Process: Raw material → Dosing → Grinding → Classification

• Finished Product Processing: Collection → Packaging → Warehousing

Calcination Process (β-hemihydrate gypsum):

• Calcination Temperature: 150-180°C

• Calcination Time: 1.5-2 hours

• Dehydration Rate: ≥75%
