The Gypsum Importation Landscape and Crushing/Sand-Making Industry in Nigeria: A Comprehensive Overview
Nigeria’s construction sector is experiencing rapid growth, driven by urbanization, infrastructure projects, and housing demands. As a key raw material, gypsum is essential for cement production, plasterboard manufacturing, and soil conditioning. Despite local gypsum deposits in states like Sokoto and Adamawa, Nigeria still relies heavily on imports due to insufficient mining capacity and processing infrastructure. This reliance creates opportunities for crushing and sand-making equipment suppliers to support gypsum processing for construction applications.
Meanwhile, the demand for sand and aggregates (crushed stone, gravel, manufactured sand) is surging. Natural sand scarcity and environmental restrictions have shifted focus to mechanized sand-making solutions, making crushing/screening equipment indispensable for producing high-quality artificial sand (M-sand) and aggregates.

1. Jaw Crusher: Primary crushing of large gypsum/rock chunks (e.g., feed size ≤1,500mm).
2. Impact Crusher/Cone Crusher: Secondary crushing for finer output (≤50mm), ideal for gypsum or granite aggregates.
3. Sand Maker (VSI Crusher): Produces 0–5mm M-sand with cubical particles, critical for concrete mixes.
4. Vibrating Screens & Feeders: Ensure graded sizing (e.g., 0–5mm, 5–10mm, 10–20mm).
5. Dust Control Systems: Essential for gypsum processing to mitigate airborne particles.

– Cement retarder: ~5% gypsum added to clinker.
– Plasterboards: High-purity gypsum required (~85% CaSO₄·2H₂O).

Q1: Can Nigeria’s local gypsum replace imports?
A: Not yet—limited calcination facilities hinder high-value plasterboard production. Imports fill the quality gap.
Q2: What’s the ROI for a 200tph sand-making plant?
A: ~12–18 months in Lagos/Abuja markets where M-sand sells at ₦4,500–₦6,000/tonne.
Q3: How to mitigate dust in gypsum crushing?
A: Wet crushing or pulse-jet bag filters reduce dust to <10mg/m³ (OSHA standards).

Client: A cement manufacturer in Ogun State.
Challenge: Process imported gypsum lumps into ≤30mm feedstock for kilns.
Solution: Deployed a jaw crusher + roller crusher combo with a closed-circuit screen system, achieving 95% passing 30mm at 50tph capacity. Dust suppression nozzles were integrated to meet environmental compliance.

With Nigeria’s cement production projected to exceed 50MT/year by 2030, investments in localized gypsum processing and sustainable sand-making tech (like hybrid power crushers) will be pivotal—offering lucrative avenues for equipment suppliers and plant operators alike.
