Operations

Talc processing

Processing turns sorted talc lumps into mesh powder of a consistent particle size. The lumps are crushed and screened, ground in hammer and Raymond mills, and classified to the target fineness. The powder is then tested and packed in 25 kg bags or jumbo bags. Grinding happens at two meshing plants in Hayatabad Industrial Zone, Peshawar.

Process flow

Eight stages from lump to loaded bag

Choose a stage to see it on site. Full detail for each stage follows below.

  1. Lumps are received, stockpiled and kept separate by grade.

  2. Lumps are reduced to a uniform feed size.

  1. Intake & segregation

    Lumps are received, stockpiled and kept separate by grade.

    Truckloads of sorted lumps arrive at the Peshawar yard and are stockpiled by source and colour grade. Keeping grades apart at this stage is what allows a buyer's specification to be met later.

  2. Crushing & screening

    Lumps are reduced to a uniform feed size.

    Crushers break the lumps down, and screens with conveyor stackers build stockpiles of crushed talc. The result is an even feed size for the mills.

  3. Grinding

    Hammer mill and Raymond mill lines produce mesh powder.

    The meshing plants run hammer mill and Raymond-type roller mill lines. Crushed talc is ground and swept by air into a cyclone, where powder of the right size is collected. Oversize material goes back to the mill.

    Talc is soft (Mohs 1), so the grinding task is mainly about controlling particle size and keeping the product clean.

  4. Classification & micronizing

    Air classifiers cut the powder to finer particle sizes.

    For finer grades, a micronizing classifier separates particles by size in an air stream. It is set to the mesh or micron target in the order.

  5. Dust collection

    Cyclones and collectors keep powder in the process and out of the air.

    Each mill line has cyclones and a dust-collection hopper. They recover fine product and limit airborne dust in the shed. Mills are serviced regularly to keep output consistent.

  6. Testing

    Samples go to SKZ Laboratory Peshawar.

    Powder samples are checked for particle size, whiteness, sieve residue, bulk density, loss on ignition, silica and magnesia. The quality control page shows the full method.

  7. Packing

    25 kg bags and jumbo bags, filled under dust collection.

    Powder is filled into printed 25 kg SKZ Soap Stone / Talc Powder bags or into jumbo bags under a hopper with dust collection. Bags are stacked, wrapped and palletised as the order requires.

  8. Storage & dispatch

    Covered storage, then container loading for export.

    Filled bags are stored in rows in the warehouse and yard until dispatch. Export orders go by truck to the Karachi warehouse for final packing and container loading.
