The INVENT GRF-Mixer is characterized by its versatile customization options, making it ideal for numerous mixing tasks in smaller containers.
The GRF-Mixer is a gear agitator in which the stirring shaft is directly mounted to the hollow shaft of the parallel shaft geared drive. This eliminates the need for an additional bearing housing. The gear bearings are optimally tailored to the respective requirements and are also adequately dimensioned.
With shaft lengths up to 6,000 mm and motor powers of 75.0 kW or even higher, numerous application possibilities arise. The GRF-Mixer is available in various gear ratios for speeds ranging from 1 to 400 rpm. The agitator shafts are balanced for concentric run after assembly of the mixer.
Upon request, the GRF-Mixer can be supplied with a frequency converter motor of up to 7.5 kW. Additionally, there is a type test certificate for explosive zone 0.

Applications of the INVENT GRF-Mixer
With flash mixing or fast mixing processes, the hydraulic residence time is only a few seconds. In order to achieve good mixing in this short time, the aerodynamically optimized GRF-Mixer was developed. It combines operation at high speeds with a flow-optimized stirring blade and is therefore the perfect solution.
The GRF-Mixer is the optimal solution for an excellent homogenization result. Due to the sophisticated design of the agitator blade, the fluid is accelerated both in the axial and in the radial direction and thus achieves a perfect mixing result.
For the destabilization of the colloidal state, a high energy input and a long contact time between the flocculant and the colloid are required for the formation of micro flocs. The GRF-Mixer combines these aspects with its flow-optimized agitator blade shape and its design for high speeds.
