Pigment and Colorant Mixing Equipment | Powder Blending Solutions

Pigment and colorant mixing equipment from Deyue: ribbon, paddle-ribbon, twin-shaft and conical mixers for uniform color, low dust and ATEX options.
From titanium dioxide to iron-oxide and phthalocyanine, dry pigments demand mixing that delivers uniform color without breaking agglomerates or generating heat. Deyue supplies pigment mixing systems engineered for high color consistency (< 0.5 % variation) and safe handling of fine, dusty powders.
Common Pigment Mixing Challenges
- Agglomeration: sub-micron particles re-clump; intensity must break lumps without over-grinding.
- Color uniformity: final shade depends on homogeneous dispersion of tiny color lots into large bases.
- Dust and explosion risk: organic pigments are combustible; containment and ATEX options matter.
- Contamination: cross-batch carryover ruins shade; quick clean-down is essential.
- Shear sensitivity: some treated pigments degrade under high shear.
Recommended Deyue Mixers for Pigments
For volume production, the DLH ribbon blender offers economical, repeatable batches from 35 L to 15 m³. When agglomerates dominate, the DPH paddle-ribbon mixer adds intensive paddle action that disperses lumps and reaches < 0.5 % CV. Fast-cycle lines use the DJH twin-shaft paddle mixer, with a continuous variant (DJHX) for tonnage. Shear-sensitive lots blend gently in the DSHL conical screw mixer, and lab or R&D sits on the DEH laboratory mixer.
Typical Specifications
| Model | Working volume | Power | Best for |
|---|---|---|---|
| DLH-1000 | 1,000 L | 15.0 kW | Free-flowing pigments, volume |
| DPH-1000 | 1,000 L | 18.5 kW | Agglomerates, high uniformity |
| DJH-1000 | 1,000 L | 22.0 kW | Fast cycle, intensive |
| DSHL-1000 | 1,000 L | 5.5 kW | Shear-sensitive lots |
Ancillary Systems: Feeding, Conveying, Packing
A closed, low-dust line pairs the mixer with a bag-dump station, vacuum or screw conveying, and valve-bag packing. Dust collection at each transfer point keeps the shade clean and the workplace safe.
Typical Process Workflow
- Bag dumping with dust capture.
- Weigh and charge into the mixer.
- Blend to target homogeneity (8-15 min typical).
- Optional drying in a DRH vacuum mixer.
- Convey and pack into valve bags or FIBC.
Why Deyue for Pigment Mixing
316L contact surfaces, optional ATEX-rated construction, documented validation packages, and fast spare parts. Talk to our engineers to size a line for your pigment and throughput. See also our pigments application page.
FAQ
- Which mixer gives the best color uniformity? The DPH paddle-ribbon reaches < 0.5 % CV for agglomerated pigments.
- Do you handle explosive organic pigments? Yes, with ATEX options and dust containment.
- How fast is batch changeover? Removable drums and CIP cut clean-down to minutes.
- Can the line be continuous? DJHX handles tonnage in a continuous loop.
