Ribbon Blenders

At Harsha Engineers India, we specialize in the design and fabrication of robust Ribbon Blenders for uniform and efficient mixing of dry powders, granules, and bulk solids. These blenders feature a horizontal trough with a precisely engineered double-helical ribbon agitator that moves materials in a counter-current flow—both radially and laterally—ensuring fast and homogeneous mixing. Our ribbon blenders are ideal for industries such as pharmaceuticals, food, chemicals, and agro-products, where consistent blending and batch integrity are essential.

Manufactured using high-grade stainless steel or mild steel, depending on the application, our ribbon blenders are available in various sizes and configurations. Optional features include jacketed construction for heating or cooling, variable speed drives, pneumatic or manual discharge valves, and CIP (Clean-in-Place) systems for hygienic operations. Designed for easy operation and maintenance, Harsha Engineers’ ribbon blenders offer high efficiency, low energy consumption, and long service life—making them a preferred choice for batch mixing applications requiring precision and reliability.

Ribbon Blenders are one of the most popular and versatile mixing equipment used for the homogeneous blending of dry powders, granules, and bulk materials. They feature a U-shaped horizontal trough with a specially designed helical ribbon agitator that provides efficient mixing through a triple-action mechanism—moving materials radially, laterally, and tangentially. At Harsha Engineers, we design and manufacture high-performance Ribbon Blenders in MS, SS 304, SS 316, and GMP-compliant models, ensuring durability, hygiene, and efficiency for diverse industrial needs.

The principle of convective mixing and counter-flow movement underpins the operation of ribbon blenders:

Materials are moved in one direction by the outer ribbon and in the opposite direction by the inner ribbon.
Materials of varying bulk densities and particle sizes are thoroughly blended by this continuous counterflow.
The result is a fast, efficient, and uniform mixture within a short mixing cycle.

Fabricated in Mild Steel, Stainless Steel 304/316, or special alloys.
U-shaped horizontal trough with helical ribbon agitator.
The capacities that are available range from small lab models to large industrial models.
Options for heating/cooling jacketed construction.
Bottom discharge valves make it simple to remove material.
High mixing efficiency with low power consumption.
Simple to operate, maintain, and clean.

Ribbon Blenders are widely used across various industries, including:

Pharmaceutical Industry – blending of bulk drugs, excipients, and formulations.
Food and beverages include the preparation of coffee, protein powders, spices, flour, and other food ingredients.
Chemical Industry – blending of detergents, fertilizers, pigments, resins, and specialty chemicals.
Cosmetics & Personal Care – uniform mixing of powders and cosmetic bases.
Agro Industry – blending of animal feed, pesticides, and agrochemicals.

Efficient Mixing – achieves homogeneity in a short time.
It can handle powders, granules, and small amounts of liquids thanks to its versatile design.
Strong and long-lasting performance thanks to the sturdy construction.
Customizable – available in different sizes, materials, and configurations.
