High Speed Mixers

High Speed Mixers

High Speed Mixers are designed for bench-top operation. Each lift-off tank can be placed on a scale so that ingredients can be weighed directly and conveniently. Tanks are locked to the mixer quickly, easily and safely.

Working Principles

A thermocouple is mounted in the baffle blade to monitor product temperature, which is displayed on the facia. Impellor speeds can be adjusted for optimum mixing, and the modular impellor can be reconfigured for different materials. Mixing cycles can be preset for repeatable batches. On completion of the mixing cycle, the tank can be removed easily from the mixer, to carry product to downstream processing.

Advantages

High-speed premixing ensures efficient distribution of the many ingredients in a powder coatings formulation, with the added benefit of breaking down resin flakes to give a uniform pre-blend. Trials have shown that high-speed premixing improves color development and allows the same color strength to be obtained with lower pigment concentrations. High Speed dry-blends can be prepared with a wax dispersion aid. The pilot mixer is used to heat the polymer granules so that wax melts and pigment adhere to the granules’ surfaces. As in PVC dry-blend applications, an optional feature allows a maximum product temperature to be preset so that when the temperature is reached, the mixer will automatically reduce impellor speed and open a solenoid valve for bowl cooling.
