Production line and factory setup overview
A small dry-powder plant producing one validated interior wall putty or cementitious skim coat from released gypsum or cement binder, calcium-carbonate filler, controlled fine mineral powder and precisely weighed functional additives. The route covers dry receiving, screening, major and micro dosing, uniform mixing, dust-contained transfer, valve-bag filling, coding, palletising, laboratory release and dry storage. Gypsum and cement recipes are not interchangeable.
Recommended lowest-entry line configuration Launch one interior product after local wall-substrate trials. Screen a 1-3 t/h line with three major-ingredient scales, a locked micro-additive bench, 1,000-1,500 L ribbon mixer, finished bin, pulse dust collector, 20-25 kg valve packer and a small application laboratory. Buy dry screened minerals initially; add grinding or drying only after demand and feed tests justify it.
Production process and implementation sequence
- Dry binder and filler receiving and release
- Screening and foreign-matter control
- Calibrated major-ingredient batching
- Locked micro-additive weighing
- Controlled charging and ribbon mixing
- Finished-powder buffering and dust extraction
- Valve-bag filling, check weighing and coding
- Application testing, palletising and dry storage
Products, capacity and market fit
- Afghan gypsum and calcium carbonate can supply much of the product mass when purity and fineness are controlled.
- Factory micro-dosing improves consistency over site-mixed finishing compounds.
- One interior formula keeps additive stock, claims and laboratory work manageable.
- Adhesion, sanding, cracking and shelf life must be proven on local substrates.
- Interior wall putty - Approved binder route, fineness, water demand, workability, sanding, adhesion, shrinkage and colour - Painters, plasterers, contractors and building-material distributors
- Cementitious skim coat - Separate moisture-resistant formula and substrate validation - Masonry and concrete finishing after independent trials
