Applications
Find your industry
Each application has its own guide – feeds, rotor choice, temperatures and the questions to ask before you buy.
What we dry
Feeds that suit a spin flash dryer
| Industry | Typical feeds |
|---|---|
| Pigments & dyes | Organic and inorganic pigment press cake, dye intermediates, iron oxide, optical brighteners |
| Chemicals | Chemical wet cake, inorganic salts, catalysts, silicates, carbonates, phosphates, fillers |
| Agrochemicals | J-acid and other intermediates, active ingredients, herbicide and fungicide wet cake |
| Minerals | Clays, kaolin, calcium carbonate, metal hydroxides and oxides |
| Environment | Dewatered ETP sludge, industrial sludge, filter cake from effluent treatment |
| Food & feed | Starch, protein and fibre cakes, food by-products |
| Pharma & specialty | Intermediates and specialty cakes that tolerate short, hot drying |
Acmefil spin flash dryers
Built for the feeds other dryers can’t handle
Two rotor designs, set up for the cake you have. Pick a type or a feed to read its full guide.
Pin mill type spin flash dryer
Rows of pins on the rotor and the base plate shear sticky, gelatinous cake into fine particles inside the hot air.
- Sticky & gelatinous cake
- Fine, uniform powder
- Pigments & agrochemicals
Cage mill type spin flash dryer
A rotating cage of bars breaks heavy wet cake and viscous sludge – robust, open and hard to choke.
- Heavy wet cake
- High-viscosity sludge
- Robust, low clogging
Wet cake dryer
Wet filter cake from a centrifuge or nutsche turned into dry, free-flowing powder in one pass.
- Centrifuge & nutsche cake
- One continuous step
- No separate milling
Filter press cake dryer
Lumpy filter press cake is broken up as it dries – no pre-crushing, no tray dryer bottleneck.
- Filter press cake
- Lumps broken in the dryer
- Replaces tray dryers
Sticky wet cake dryer
Back-mixing with dry powder and an agitated feed keep sticky, slimy cake from clogging the plant.
- Slimy & gelatinous
- No clogging
- Steady feeding
Paste & high-viscosity sludge dryer
Thick pastes that cannot be pumped to a spray dryer are fed by screw and dried straight to powder.
- Non-pumpable pastes
- Viscous sludge
- Powder in one step
Pigment dryer
Pigment press cake dried and de-agglomerated together – fine, soft powder with good colour strength.
- Pigment press cake
- Soft, fine powder
- Colour strength kept
ETP sludge dryer
Industrial effluent treatment sludge dried to a stable, low-volume powder for disposal or reuse.
- ETP sludge
- Lower disposal volume
- Stable dry solids
Dryer selector
Which dryer fits your feed?
Three quick questions for a starting point. Our process engineers confirm it on your feed data or in a pilot trial.
Pin mill type spin flash dryer
General guidance only – the final choice depends on moisture, stickiness, heat sensitivity and capacity. We confirm it on your feed or in a pilot trial.
