Production line and factory setup overview
This proposal presents a dry-process mini cement plant centered on controlled limestone crushing, raw-meal preparation, preheating, rotary-kiln clinker production, cooling, finish grinding and bagging. A 300-500 ton/day configuration provides a practical reference point, while the final design must follow limestone chemistry, fuel availability, environmental permitting and market demand.
Recommended lowest-entry line configuration Phased 100-300 tons/day dry-process mini cement plant using economical Chinese machinery, local civil works and semi-automatic bagging, expandable toward 500 tons/day after market validation.
Production process and implementation sequence
- Crushing
- Raw grinding
- Homogenizing
- Preheating
- Clinker burning
- Cooling
- Finish grinding
- Packing
Products, capacity and market fit
- Cement is a strategic input for housing, roads and public infrastructure.
- Domestic clinker and cement capacity can reduce exposure to cross-border supply disruption.
- Afghanistan has limestone resources that warrant location-specific geological and chemical assessment.
- Bulk and bagged product options serve ready-mix, block, precast and retail channels.
- Ordinary Portland cement - Market grade subject to local standard - General construction
- High-early-strength cement - Adjusted clinker and gypsum recipe - Precast and fast-track works
- Blended cement - Clinker plus approved mineral additions - Cost and durability applications
- Bulk cement - Tanker dispatch - Ready-mix and block factories
