Gypsum crusher For Manufacturing

A gypsum crusher is essential in the manufacturing process of gypsum-based products, such as plaster, drywall (gypsum board), and cement. Crushing gypsum rock into smaller particles ensures proper processing and quality control. Below are key aspects to consider when selecting or operating a gypsum crusher for manufacturing:

—

1. Types of Gypsum Crushers

Different crushers are used depending on the required particle size and production capacity:

• Jaw Crusher:

– Primary crushing of large gypsum rocks (up to 1-1.5m diameter).
– Output size: ~150-300mm.
– Suitable for initial coarse crushing.

• Hammer Crusher:

– Secondary crushing for medium-hardness gypsum.
– Output size: ≤25mm (adjustable).
– Ideal for producing finer particles for calcination.

• Impact Crusher:

– High-speed rotor crushes gypsum into cubical shapes.
– Output size: ≤50mm (suitable for drywall production).

• Cone Crusher:

– Used for intermediate crushing with higher efficiency.

• Roller Crusher:

– Produces uniform particle sizes (~5-10mm) with low dust generation.

2. Key Considerations for Manufacturing

When choosing a gypsum crusher, consider:

(a) Feed Size & Output Requirements

• Raw gypsum rocks vary in hardness and size; select a crusher that matches your feed material.
• Final product fineness depends on downstream processes (e.g., calcination requires ≤30mm).

(b) Moisture Content

• Gypsum can contain up to 20% moisture. Wet/sticky material may require:

– Pre-drying before crushing.
– A crusher with anti-clogging features (e.g., hammer mills with grate bars).

(c) Production Capacity

• Small-scale plants: ~5–50 tons/hour (hammer/impact crushers).
• Large-scale plants: ~100–500 tons/hour (jaw + cone/roller crushers).

(d) Dust Control

• Gypsum dust is hazardous and can cause equipment clogging.
