Dyestuff and pigment manufacturers dry, grind and standardise colour powders before packing. A vibro sifter removes agglomerates and oversize after drying and grinding, and check-screens the standardised product so the customer receives a uniform, free-flowing powder.
Applications
- Sifting after spray drying or tray drying of dyes.
- Removing oversize after grinding of pigments.
- Grading dye intermediates.
- Check screening before drum or bag filling.
Considerations
- Strong colours demand thorough cleaning – stainless steel surfaces wash clean.
- Fine dye dust should be contained; the lidded design helps.
- Some intermediates are handled with solvents – a flameproof option is available.
- Throughput for bulk products may call for a 48″–72″ industrial model.
Gujarat's Dyes Clusters
Much of India's dyes and intermediates production is located in Gujarat – around Ahmedabad (Vatva, Naroda, Odhav), Ankleshwar and Vapi. Being based in Ahmedabad, we can reach these estates quickly for discussions and deliveries.
