Horizontal Ribbon Mixer for Powder Blending

PRM Horizontal Ribbon Mixer & Powder Blender

The PRM ribbon mixer comprises a U-shape container, transmission parts and spiral belt agitating blades — usually double or triple layers, with the outside screw gathering material from the sides to the center and the inside screw transferring material from the center to the sides, forming a strong convection mix. It delivers reliable results for viscous or cohesive powders and for incorporating liquid and paste additives into powder, and the cylinder cover opens fully for fast cleaning and batch changeover.

Core Technology & Working Principle

During rotation, the outer ribbon pushes material from the wall toward the center while the inner ribbon returns it from the center to the wall. The counter-current flow drives continuous turnover and radial transfer, achieving homogeneous mixing across the full 0.5–15 m³ tank range. Explosion-proof configurations are available upon request.

▲ Double-Spiral Convection Agitation

Outer and inner ribbons move material in opposite directions, creating a three-dimensional convection that eliminates dead zones and shortens blend time to 3–8 minutes for most dry powders.

▲ Viscous & Cohesive Powder Ready

Engineered for powders with cohesion and moderate viscosity, plus uniform liquid and paste injection through optional spray bars — not only free-flowing materials.

▲ Fully Open Top Cover

The cylinder cover swings fully open for rapid cleaning and product changeover — well suited for multi-SKU and frequent-batch manufacturing plants.

Precision Engineered Details

The components below are what plant teams interact with every shift — built to survive cohesive powder duty, daily washdowns and years of continuous batch cycling.

U-Shape Mixing Vessel

Welded body with full top cover opening for fast cleaning and changeover between batches.

Double Ribbon Agitator Shaft

Counter-direction outer and inner ribbons drive the three-dimensional convection mixing action.

Bottom Discharge Valve

Pneumatic or manual discharge for clean, residue-free batch release at the end of every cycle.

Drive and reduction gearbox of ribbon mixer

Drive & Reduction Gearbox

Belt or coupling drive with hardened reducer for stable low-speed, high-torque shaft rotation.

Technical FAQ

Short answers to the questions plant managers ask before specifying a horizontal ribbon mixer.

What powders can the PRM ribbon mixer handle?

It is designed for free-flowing to cohesive dry powders and for blending liquid or paste additives into powder. For ultra-high-viscosity masses above ~1,000,000 cps, our PMX vacuum planetary mixer is the better fit — the ribbon mixer is not intended for that range.

How long does one batch take?

Typical dry-powder blending completes in 3–8 minutes thanks to counter-current convection. Adding liquids or high filler loads extends the cycle; spray-bar dosing keeps it uniform.

Carbon steel or stainless steel — which to choose?

Use stainless steel (SS304 / SS316L) for food, pharmaceutical, pigment and corrosive duty; carbon steel is cost-effective for general building materials and non-reactive powders. Both are customizable.

How does the double-ribbon convection work?

The outer ribbon pushes material from the wall toward the center while the inner ribbon returns it from the center to the wall. This opposite-direction flow creates continuous turnover and radial transfer, eliminating dead zones.

Can I add liquid or essence during mixing?

Yes. Optional spray bars inject liquid uniformly. For duties needing up to 20% spray addition with intensive dispersion, the PYPM horizontal plough mixer is recommended.

What is the lead time and warranty?

Standard PRM models deliver in 30-45 days from confirmed drawings. Every unit carries a 3-year global warranty — double the common 1-year industry standard.
