Until now, powders with uniform-sized particles were achievable only in the
large nozzle towers. NARROWSPAN™, however, achieves this uniformity, creating a
largely dust free, easily wettable product with a high flowability, from a
rotary atomizer wheel. This reduces costs and allows the use of smaller
buildings to house the plant equipment. The NARROWSPAN™ is suitable for
new-build projects, or for retrofit to improve the efficiency of existing
production plants.
- The NARROWSPAN™ produces a low-dust product, which is important for
explosion safety, personal health, and the environment.
- The uniform particle size distribution means a controlled functionality of
the final product.
- A high bulk density can be achieved together with a free flowing product
with large particle size.
- The product does not break into fines, compared with agglomerates that are
generally more brittle.
- NARROWSPAN™ products are easier to disperse and wet in their respective
solvents.
- Large, uniform, free flowing particles allow easy handling and packing.
- Variation in particle size from fine to coarse is possible while running
the plant by controlling the rotation speed of the atomizer wheel.
- Large particles can be produced in smaller diameter chambers.
- Rebuilding of existing plants allows for the manufacture of added value
products.
- Low building height and hence investment costs, compared to nozzle towers.
These features are all proven in tests and have been working in
industrial applications for the last decade.
