Production line and factory setup overview
A medium-industrial dry mineral line converting released Afghan talc ore into buyer-specified ground talc through covered receiving, hand sorting or optical colour sorting where justified, staged crushing, magnetic metal removal, controlled drying, buffer feeding, gentle Raymond or air-classifier milling, dynamic classification and oversize return, cyclone and baghouse collection, product silos, laboratory release and valve- or jumbo-bag packing. Beneficiation and surface coating are separate unless contracted.
Recommended lowest-entry line configuration Start only after one mine bench and one buyer approve mineralogy, asbestos absence, whiteness and particle-size distribution. Screen a 1-3 t/h line producing one 200-325 mesh industrial grade with jaw/hammer crushing, magnet, dryer only if required, one Raymond mill with dynamic classifier, cyclone, baghouse, silo, bagger and an outsourced XRD/asbestos protocol plus in-house whiteness and size checks.
Production process and implementation sequence
- Ore receiving, lot coding and mineral release
- Sorting and staged crushing
- Magnetic metal removal
- Controlled drying where required
- Buffered mill feeding
- Gentle grinding and dynamic classification
- Cyclone/baghouse collection and silo storage
- Laboratory release, packing and dry dispatch
Products, capacity and market fit
- Afghan talc can retain more value through controlled grinding and verified mineral safety.
- One industrial grade is simpler and safer than claiming cosmetic, pharmaceutical or food use.
- Dynamic classification improves repeatability and avoids selling unverified mesh-only powder.
- Asbestos screening, silica control and dust exposure management are non-negotiable.
- Industrial ground talc - Buyer-approved mineralogy, no detected asbestos by named method, whiteness, moisture and particle-size distribution - Ceramics, coatings, putty and selected polymer compounders
- Coarser technical talc - Separate buyer grading and chemistry after trials - Selected construction and ceramic formulations
Core production machinery and line specifications
| Machine / stage | Function / value | Production note |
|---|---|---|
