Rotary Drum Mixer
Tiermax can offer rotary drum mixer for mixing and processing fine powders, granulates and natural products. Our rotary drum mixers quickly blend and process large volumes in an efficient, reliable process that uses very little energy. Our rotary drum mixers never stress or heat particles through shear force. Gravity makes sure every particle keeps its original size, shape and properties. This is how we bring out the best in your chemical, polymer and mineral products. The rotary drum mixing principle is based on the free flow of product throughout a relatively slowly rotating vessel, which is equipped with specially shaped and oriented vanes. The product is introduced through the inlet at the center line of the vessel. Rotation and gravity gently redistribute the product randomly. Accumulation of product at the outlet side causes a backflow. These flows combined create the gentle mixing action resulting in a homogeneous product within typically 1- 5 minutes. After opening the outlet valve, the product leaves the rotary drum mixer in a matter of a mere few minutes, gently propelled by the vanes. The rotary drum mixer empties itself completely.

Rotary drum mixer
Due to the fact that each and every particle always moves, this principle is highly useful for other application. Beside mixing, this rotary drum mixers offers a very effective way to process powders and granulate in others ways than just mixing, example are:
– Liquid injection: impregnation, coating, wetting
– Heat transfer: cooling, heating, drying
– Freezing
– Disinfection
Rotary drum mixer for food industry:
For food, sanitary design and easiness of cleaning are essential. Special attention and effort are put into the quality of the welds and surface finish. All metal parts that come in contact with the product are made of stainless steel (AISI 316L or AISI 304). All other parts are made of FDA approved materials. On request, frame and other parts can also made of stainless steel. To facilitate extra quick and easy cleaning and maintenance the rotary drum mixer can be equipped with retractable inlet and outlet – QSR.

Frequently Asked Questions
A Rotary Drum Mixer is an industrial mixing machine designed for the gentle and homogeneous blending of powders, granules, and bulk materials. The mixer uses a slowly rotating horizontal drum equipped with specially designed vanes to create a controlled product flow, allowing materials to mix efficiently while maintaining their original particle size and properties.
A Rotary Drum Mixer works by rotating a horizontal mixing vessel at a low speed. As the drum rotates, internal vanes lift and redistribute the material through gravity-driven movement. The combination of product flow, backflow, and gentle redistribution creates a uniform mixture with minimal segregation and low mechanical stress.
A Rotary Drum Mixer is suitable for mixing a wide range of dry bulk materials, including fine powders, granules, chemicals, polymers, minerals, food ingredients, pharmaceutical powders, and natural products. Its gentle tumbling action minimizes particle degradation, making it ideal for fragile and sensitive materials that require uniform blending without damage.
An Industrial Rotary Drum Mixer delivers excellent mixing uniformity with low energy consumption while minimizing product degradation and segregation. Its gentle, friction-free mixing action prevents heat generation, making it ideal for sensitive materials, while its simple design ensures easy cleaning, low maintenance, and reliable operation.
The mixing time depends on the product characteristics, batch size, and required homogeneity. In many applications, a Rotary Drum Mixer can achieve a homogeneous mixture within approximately 1–5 minutes due to its efficient gravity-based mixing principle.
