Production line and factory setup overview
A small/medium construction-material line converting released dry graded sand, cement and mineral filler into one or more factory-controlled dry mortars through covered ingredient storage, sand drying and screening only if incoming sand is not specification-dry, calibrated major-ingredient and micro-additive batching, low-shear high-uniformity mixing, finished-product buffering, dust-controlled valve-bag filling, weight checking, coding, palletizing, laboratory release and dry storage.
Recommended lowest-entry line configuration Begin with one masonry or plastering mortar validated with local sand and cement. Where specification-dry screened sand can be purchased, screen a 1-3 t/h compact line with four weighed major ingredients, a locked micro-additive station, 1,000-1,500 L ribbon or ploughshare mixer, finished bin, pulse dust collector, 25-40 kg valve packer and mortar laboratory. Add a sand dryer only after a year-round moisture study.
Production process and implementation sequence
- Dry sand, cement and filler receiving/release
- Sand drying and screening where required
- Major-ingredient storage and weighing
- Locked micro-additive weighing
- Batch mixing and uniformity control
- Finished-product buffering
- Valve-bag filling, weight check and coding
- Laboratory release, palletizing and dry storage
Products, capacity and market fit
- Factory blending improves mortar consistency compared with uncontrolled site mixing.
- Local sand and mineral filler can contribute most of the mass when grading and moisture are controlled.
- One basic mortar recipe minimizes additives, laboratory complexity and inventory.
- A simple mixer-only listing is incomplete without dosing, dust control, packing and product testing.
- Masonry dry mortar - Buyer-defined compressive strength, workability, water demand, open time and bag yield - Block/brick masons and contractors
- Plastering dry mortar - Separate grading, adhesion, workability, shrinkage and finish specification - Plaster contractors after field trials
Core production machinery and line specifications
| Machine / stage | Function / value | Production note |
|---|---|---|
| Ingredient bins and calibrated scales | Meters sand, cement and filler accurately | Four major ingredients |
| Locked micro-additive station | Controls low-dose chemistry | Double-check weighing |
| Ribbon or ploughshare mixer | Produces uniform dry mortar batches | 1,000-1,500 L |
| Screw/elevator transfer | Moves powders in enclosed routes | Low segregation |
| Finished-product buffer bin | Decouples mixing from packing | Anti-bridging design |
| Pulse dust collection | Contains cement and silica-bearing dust | All transfer/packing points |
| Valve-bag packer and check scale | Fills controlled 25-40 kg bags | One bag size at launch |
| Mortar laboratory | Tests fresh and hardened performance | Local substrate trials |
Raw materials, utilities and factory requirements
- Dry graded Afghan sand with controlled moisture and clay
- Released cement and mineral filler
- Only validated cellulose ether, polymer or other additives for the chosen recipe
- Valve bags, pallets, wrap, labels, mixer seals and filter spares
- Three-phase power and compressed air
- Dry enclosed ingredient and finished-bag warehouse
- Dust extraction and respirable-silica worker controls
- Potable laboratory water and controlled curing area
- Optional dryer fuel and emissions only if wet sand must be processed
Indicative low-entry investment and implementation plan
