Feasibility Study for a Cement Company in Tanzania: Focus on Crushing & Sand-Making Production Lines

1. Industry Background
Tanzania’s construction sector is booming, driven by infrastructure projects (roads, dams, housing) and urbanization. Demand for high-quality sand and aggregates has surged, making crushing/sand-making equipment a critical investment. Cement companies diversifying into sand production can capitalize on synergies in raw material sourcing (limestone, basalt, granite) and logistics.

2. Core Equipment & Process Flow
A typical crushing/sand-making line includes:

• Primary Crushing: Jaw crusher (for large rocks ≤1200mm).
• Secondary Crushing: Cone crusher or impact crusher (for medium-sized stones ≤350mm).
• Sand Making: Vertical shaft impact crusher (VSI) or roller crusher (producing 0–5mm sand).
• Auxiliary Units: Vibrating screens, belt conveyors, dust collectors.

Process Example:
Raw ore → Jaw crusher (coarse crushing) → Cone crusher (fine crushing) → VSI (shaping) → Screening → Washed sand (optional).

3. Market & Applications

• Product Types: Machine-made sand (replacing river sand), 5–20mm aggregates (concrete), 20–40mm gravel (road base).
• Key Buyers: Ready-mix concrete plants, construction firms, government infrastructure projects.
• Competitive Edge: Tanzania’s river sand bans (due to environmental concerns) favor machine-made sand. Local limestone deposits reduce raw material costs for integrated cement+sand producers.



4. Common FAQs
Q1: What’s the ROI for a 200t/h sand-making line?
A: Capex: ~$1.5M (equipment + installation). Assuming sand price: $15/ton, profit margin: $5/ton, breakeven in 2–3 years.



Q2: How to control dust pollution?
A: Use wet dust suppression systems or closed-circuit plants with bag filters.

Q3: Equipment lifespan?
A: 10–15 years for crushers (with regular maintenance). Wear parts (blow bars, mantles) need replacement every 6–12 months.

5. Project Case
Client: A Tanzanian cement plant adding a sand-making line.

• Configuration: PE750×1060 jaw crusher + HPT300 cone crusher + VSI1140 sand maker.
• Output: 150t/h (0–5mm sand), 50t/h (10–20mm aggregate).
• Result: Supplied 30% of sand demand for the company’s concrete division, cutting external procurement costs by 40%.

6. Challenges & Solutions

• Power Supply: Opt for diesel generators as backup in rural areas.
• Moisture Content: Dry sand production is ideal for cement mixing; add a dryer if humidity exceeds 3%.

Conclusion
Integrating crushing/sand-making lines into cement operations in Tanzania offers a scalable revenue stream. Key success factors include selecting robust equipment, optimizing mineral waste utilization, and targeting infrastructure-led demand.

(Note: Customize capacity, ore type, and budget per project specifics.)
