Mixing Equipment / WLDH
WLDH Series Horizontal Ribbon Mixer for Food and Pharmaceutical Powder Blending
Model: WLDH
A horizontal ribbon mixer uses inner and outer helical ribbons to circulate material through a trough. Assess this powder mixer as part of the complete mixing equipment scope, with representative dry blending and granule blending trials to check uniformity and handling after discharge.
Working Principle
Rotation of the ribbon assembly moves material in opposing axial directions and exchanges it across the vessel. The resulting circulation brings ingredients together throughout the working batch.
Key Features
- Inner and outer ribbons generate opposed axial material movement.
- Mechanical circulation exchanges ingredients through the trough.
- Dosing, sealing and discharge requirements guide configuration.
Suitable Materials
- Dry powders, granules and compatible mixtures. Liquid addition or special ingredient dosing should be reviewed as part of the actual equipment scope rather than assumed as standard.
- Confirm the actual material properties, moisture or solvent content, temperature sensitivity and target product condition before selecting the configuration.
Applications
Consider ribbon blending for compatible powder or granular formulations requiring mechanical circulation through a horizontal trough. Ingredient dosing, any liquid addition and the downstream discharge arrangement need to be specified together.

Frequently Asked Questions
What is the WLDH mixer designed to do?
A horizontal ribbon mixer uses inner and outer helical ribbons to circulate material through a trough.
What information is needed for model selection?
Specify working batch volume, bulk density, flow properties and component proportions. Review drive load, shaft sealing, discharge residue and cleaning access. Where liquids are involved, confirm addition rate and distribution requirements before selecting the final configuration.
How should mixing performance be evaluated?
Agree the formulation, batch size, sampling procedure and acceptable variation before a trial. Evaluate the discharged blend as well as the material in the vessel, because subsequent handling can affect segregation.
Selection and Configuration
For a configuration review, send the material name, bulk density, particle-size distribution, moisture level, batch mass and required blending endpoint. Working volume, drive rating, contact materials, sealing and discharge details are confirmed for the selected configuration; no numerical model rating is implied by this overview.

Application Review: Food and Pharmaceutical Powder Blending
Define the ingredients, particle-size distribution, working fill and sampling method for the proposed blend. Check uniformity after discharge as well as within the vessel.
For pharmaceutical process evaluation, consult FDA process validation guidance.
For pharmaceutical cleaning requirements, consult the FDA equipment and cleaning questions.
For food ingredients, review the Codex food hygiene and HACCP framework when defining hygienic handling.
Review the actual powder characteristics using the HSE safe handling of combustible dusts.
