Grinding & Dispersing

Controlled deagglomeration, dispersion and true grinding of solid particles in a liquid medium are the principal objectives of wet-milling technology. Particle sizes below 100 nanometres can be achieved, which other grinding techniques can often only achieve with restrictions.

DYNO-MILL ECM-AP

HIGH EFFICIENCY AGITATOR BEAD MILL: With the development of the DYNO®-MILL ECM-AP, WAB has once again proven its innovative strength.

This high-efficiency agitator bead mill is equipped with a completely new grinding bead separation system for the most difficult products to grind. One of the outstanding features of the patented separation system of the DYNO®-MILL ECM-AP series is the self-cleaning effect: It prevents screen clogging, which reduces production downtimes for screen cleaning – a considerable advantage depending on the product.

The DYNO®-MILL ECM-AP high-efficiency agitator bead mill incorporates all of WAB's experience.

DYNO-MILL UBM

UNIVERSAL AGITATOR BEAD MILL: The new DYNO®-MILL UBM series is ideal for dispersion and ultra-fine grinding.

It processes low to high-viscosity suspensions for a wide range of applications. During development, WAB placed particular emphasis on durability, ease of maintenance and the best total cost of ownership.
ENQUIRE ABOUT THIS PRODUCT
  • Unique grinding principle based on the innovative DYNO®-DISC BC agitator discs (patent pending)
  • Suitable for high throughputs
  • Ideal for the dispersion and grinding of highly viscous products
  • Long screen service life
  • Suitable for pass mode and circulation mode
  • Wide range of materials for selection of the optimal machine equipment
  • Use of grinding beads between 0.2 and 2.5 mm
  • Grinding chamber volumes from 0.5 to 100 litres
  • Ideal grinding chamber height enables ergonomic working
  • High wear resistance and thus reduced maintenance costs
  • Low-maintenance, double mechanical seal for the most exacting requirements
  • Robust, stainless steel collecting vessel for the grinding beads permanently integrated into the machine housing
  • Closed machine housing

The new generation of DYNO®-DISC BC agitator discs was specially developed for this series.

These feature unique Bead Channels in combination with a closed outer contour.

The bead channels ensure the efficient acceleration of the grinding beads along a precisely defined path. During operation, each of the bead channels creates two efficient grinding circuits between the agitator discs that work in opposite directions.

DYNO-MILL KD

With the DYNO®-MILL KD, WAB launched the first horizontal agitator bead mill on the market.

The original agitator bead mills from WAB are true all-rounders. This type of machine has been used for decades in practically all applications. The consistently growing range of materials, the material quality, and the adaptation of these models as needed to highly specialized customer requirements make this type of mill the first choice in many applications today.

The DYNO®-MILL KD disc mills are available with grinding chamber volumes from 0.15 to 600 litres and are suitable for practically all types of grinding media. The production mills can be operated with grinding bead diameters from 0.5 to 2.5 mm.
ENQUIRE ABOUT THIS PRODUCT
  • Ideal for pass mode operation with consistent efficiency and achievement of the narrowest possible particle size distribution in the micrometre range
  • The ideal equipment for every product with an extremely wide choice of materials for wear parts that come in contact with the product – including hardened steel, stainless steel, hard chrome-plated stainless steel, polyurethane, and engineered ceramics
  • Maximum operating safety – the basic model already complies with the explosion protection directive for installation in ATEX zone 1 (Ex II 2 G cb IIB T3)
  • Grinding bead diameters from 0.5 to 2.5 mm
  • Ideal cooling properties: The compulsory flow of the cooling water in the outer jacket permits the processing of temperature-sensitive products
  • Easy to use – all DYNO®-MILL KD mills can be disassembled in just a few steps
  • Simple operation and easy setting of operating parameters
  • Scale-up to all machine sizes of the DYNO®-MILL KD series
  • Low operating and maintenance costs

In the horizontal grinding chamber, the specially designed DYNO® agitator discs are mounted symmetrically on the agitator shaft. They transfer the kinetic energy required for the grinding operation to the grinding beads.

With the correct process parameters, these disc mills achieve outstanding grinding results still today, especially in pass mode operation.

The specific design of the individual machine models depends on the grinding chamber volume. The models DYNO®-MILL KD 20 to DYNO®-MILL KD 60 are optionally available with a dynamic gap separator or a screen separation system.

The Pharmaceutical Manufacturer first prepares a pumpable suspension of the solid API in a liquid medium. This raw suspension usually has a very wide particle size distribution and contains a high percentage of coarse particles. The coarse particles are mainly formed by aggregated and agglomerated API material.

The main task of the DYNO®-MILL PHARMA equipment is to disperse the aggregates and agglomerates to the Desired particle size distribution.

With the many stages and requirements in the API development process, a broad range of solutions is a helpful support.

WAB has decades of experience in the Pharmaceutical Industry and a proven spectrum of equipment to supports its global customer base.
