PSD Intensive Mixers & Dissolver Technology

Powerful and innovative solutions.
Column mixers for small to mid-size batches
Plant mixers for line production
ContiMixer for automated, continuous production
The PSD Dissolver is used for dispersing solids in liquids. The product is mixed in batches in an exchangeable tank.
In all application ranges for wet grinding and dispersion, the result of the entire process is dependent on the quality of the pre-treatment, i.e., mixing and pre-dispersion of the raw materials. PUHLER can supply the suitable solution – from individual mixing units through to complete production plants.

Column mixers for small to mid-size batches

PUHLER offers different column mixers dependent on application and product viscosity: High speed dissolvers for per-dispersion, butterfly mixers for high viscosity products and twin-shaft mixers for combined mixing and pre-dispersing.

Plant mixers for production lines

For large-scale production plants, solid and liquid components are automatically dosed into the mixing tank. The raw materials are then pre-dispersed under high energy input in the mixing tank and subsequently pumped into a holding tank. After final dispersion by means of agitated media mill or three-roll mill, the final product is fed into storage tanks.


The dissolver is a fast, high-capacity disperser with a wide range of speeds and high level of efficiency
Push-button speed control
Speed indicator and automatic speed reduction
The product is accelerated radially by the dispersion disk, deflected to the top and bottom at the tank wall and directed back to the dispersion disk through formation of a vortex Shear forces around the circumference of the toothed disk result in highly efficient dispersion, good wetting and deagglomeration
For high-viscosity products, a tank wall scraping device can aid the mixing and dispersing process
Hydraulic lifting/lowering device
Push-button stroke adjustment
Adjustable tank clamping mechanism
Stainless steel shaft and dispersion disk; additional product-specific mixing tools available depending on the application
