Gypsum Blocks Manufacturers in Iran and Their Role in the Aggregates Industry
Iran boasts a significant gypsum production sector, with numerous manufacturers specializing in gypsum blocks—a key material for lightweight construction. These producers often rely on advanced crushing and sand-making equipment to process raw gypsum into high-quality aggregates suitable for block manufacturing.
Industry Background

The demand for gypsum-based construction materials has grown steadily due to their fire resistance, thermal insulation, and ease of installation. In Iran, gypsum block manufacturers source natural or synthetic gypsum, which undergoes primary crushing, grinding, and calcination before being molded into blocks. Efficient aggregate processing is critical to ensuring consistent particle size distribution and material purity.
Crushing & Sand-Making Equipment Applications

1. Primary Crushing: Jaw crushers or hammer mills reduce large gypsum rocks to manageable sizes (typically below 50mm).
2. Secondary Grinding: Cone crushers or impact crushers further refine the material for calcination.
3. Sand-Making: For synthetic gypsum (e.g., by-products from flue gas desulfurization), vertical shaft impactors (VSIs) produce fine aggregates that enhance block strength.
Key Considerations for Equipment Selection
- Moisture Resistance: Gypsum’s hygroscopic nature demands crushers with corrosion-resistant linings.
- Dust Control: Dry processing requires integrated bag filters or wet suppression systems to comply with environmental regulations.
- Energy Efficiency: Roller crushers or high-pressure grinding rolls (HPGRs) minimize power consumption in fine grinding stages.
FAQ
Q: What crusher type is best for gypsum processing?
A: Hammer crushers are cost-effective for primary crushing, while VSIs excel in producing uniform fines for block mixtures.
Q: How does synthetic gypsum differ from natural gypsum in processing?
A: Synthetic gypsum often contains higher moisture; pre-drying or dual-stage crushing may be necessary before calcination.
Engineering Case Example
A Tehran-based manufacturer upgraded its line with a VSI sand-maker and dust collection system, achieving a 20% increase in block density while reducing waste. The plant now recycles 95% of process water, aligning with Iran’s sustainable construction initiatives.
By integrating modern crushing technologies, Iranian gypsum producers optimize both productivity and product quality—setting benchmarks for the regional aggregates industry.
