The Gyraton® silo mixer is a precision mixer. It sets new standards for silo mixers in terms of mixing quality, flexibility and cost-effectiveness and delivers ideal mixing qualities.
Maximum efficiency, tailored to your needs: you determine the mixing time and the motor size adapts precisely to it. For example, 22 kW of drive power is sufficient for mixing a 20 m³ batch. This is an efficiency advantage that has a direct impact on your operating costs.

Ideal mixing quality, small drive motor, compact design
The Gyraton® mixing silo requires only five to ten percent of the power of a conventional precision mixer. Nevertheless, it homogenises the mixed materials with the highest precision. The mixing process is extremely gentle.
The silo is very compact due to its cylindrical mixing chamber. For example, the Gyraton silo mixer for 70 m³ is less than 7.5 metres high. Compared to conical silo mixers, the height of the mixing chamber is reduced by two thirds. The compact design saves energy, as less vertical conveying is required during filling. This means less conveyor technology, less energy consumption, less cleaning effort and lower investment costs.
The bulk material also benefits. The shorter conveying distance protects the grain structure. This prevents heating and preserves the particle structure.

Easy delivery, installation and commissioning, hygienic design
The Gyraton® mixing silo is easy to transport and comes almost completely pre-assembled. It is transported horizontally and only erected at the installation site. For sizes up to 100 m³, the transport height (including vehicle) is less than four metres. Transport can be by road, rail or water.

The mixing chamber is gas-tight and hygienic. It can be cleaned dry or wet. Gyraton® mixing silos meet the highest purity requirements. On request, the silo mixer can be temperature-controlled. Even sensitive products can be mixed or fermented safely.
Large inspection doors in OmgaSeal® design facilitate cleaning. Gyraton® silo mixers are designed to be very durable. There are amixon® mixers that are still in use even after 40 years.
Gyraton® offers the best mixing quality without compromise – regardless of whether batch or continuous mixing is required
Precision mixers generally have high specific power requirements when used for powder mixtures (dry, wet or suspended). The required drive power is 20 to 30 kW per tonne of mixed material. This makes precision mixers uneconomical when large batches need to be mixed. For example, a 10 m³ mixer requires more than 100 kW. In most cases, however, more time is available than a large precision mixer requires (approx. 4 to 10 minutes).

The Gyraton® mixing silo always achieves optimum mixing quality. The mixing time can be selected by the operator. In most cases, mixing times of 30 minutes or several hours are acceptable. A small drive motor is then sufficient. The Gyraton® silo mixer can be operated both in batches and continuously.
The Gyraton® mixer achieves ideal mixing quality even with very slow mixing processes. The mixing tool performs two movements simultaneously. The shaft moves from the pivot point (gimbal centre at the top of the mixing chamber) in a precessional motion. At the same time, it rotates at a low speed. The lower mixing arm moves cycloidally over the bottom of the mixing chamber.
Since the radius of the lower mixing arm is significantly smaller than that of the mixing chamber, the required drive torque is low.
