Ribbon Blenders and Paddle Mixers

Homogeneous mixing of dry powders, granules, and meals for feed, food, and premix production.

Horizontal mixing machines for dry powders, granules, and meals. Used in feed formulation, seasoning blending, and premix production. Paddle and ribbon configurations suit different product viscosities and required mixing uniformity.

Overview

Ribbon blenders use a double-helix ribbon agitator mounted on a central shaft inside a U-trough. The outer ribbon moves material in one direction along the trough while the inner ribbon moves it in the opposite direction, achieving thorough mixing across the full batch without dead zones. Paddle mixers use angled paddles rather than a continuous ribbon, and are better suited to fragile or sticky materials where the ribbon would cause product damage or fouling. Both machine types achieve high mixing uniformity (coefficient of variation below 5%) within short batch cycle times. Facet Engineering sizes mixer capacity to the required batch weight and cycle time, and can supply with integral liquid addition systems for molasses, oil, or premix solutions.

Ribbon blender and paddle mixer models

Facet Engineering ribbon blenders and paddle mixers are custom-built to your required size. The FMRB ribbon blender and FMPM paddle mixer ranges also have the following standard sizes, as listed in the product data sheets.

Standard FMRB and FMPM models and nominal capacities
Ribbon blender modelPaddle mixer modelNominal capacity
FMRB-125FMPM-125125 litres
FMRB-250FMPM-250250 litres
FMRB-500FMPM-500500 litres
FMRB-1000FMPM-10001 000 litres
FMRB-1500FMPM-15001 500 litres

FMRB-2500FMPM-25002 500 litres
FMRB-3000FMPM-30003 000 litres

These standard sizes do not limit the custom-built range. Mixer selection must account for the product bulk density, required batch size and mixing duty. A volume in litres is not a guaranteed batch weight in kilograms.

Equipment questions and answers

What are the Facet ribbon blender and paddle mixer model ranges?

Facet Engineering supplies FMRB ribbon blenders and FMPM paddle mixers. Both ranges have standard nominal sizes of 125, 250, 500, 1,000, 1,500, 2,000, 2,500 and 3,000 litres, as listed in the product data sheets.

Can ribbon blenders and paddle mixers be made in custom sizes?

Facet Engineering ribbon blenders and paddle mixers are custom-built to the required size and mixing duty. The standard sizes in the data sheets are not a limit on the custom-built range.

Does a mixer capacity in litres specify its batch weight?

Nominal mixer capacity in litres describes volume, not a guaranteed batch weight in kilograms. Mixer selection must consider the product bulk density, required batch size and mixing duty.

Notes

Liquid addition systems are sized to the volume and viscosity of the liquid being added.

Both ribbon and paddle agitators can be supplied in stainless steel for food-contact applications.
