No rotary ball milling method can match
the speed and power of  a DAC SpeedMill®.

​

What is a DAC SpeedMill® ?

​

A DAC SpeedMill® will rapidly pulverise any wet or dry product mix using Dual Asymmetric Centrifuge (DAC) technology.

A fully enclosed rotary ball mill which uses abrasive Ceramics or hardened rings inside a sealed Mix Cup.

​

Hauschild Mix Cups are available in polypropylene (PP), aluminium (AL) or Stainless Steel (SS). 

​

​An original DAC Hauschild SpeedMixer® will provide the power to efficiently mill and grind products
with ease, safely sealed inside a sealed Hauschild Mix Cup.  

​

An original, high energy Hauschild SpeedMixer® will generate an unrivaled power producing g-force above 1000.

​

Maximizing attrition from controlled impact, collision, abrasion and friction ensures agglomerates are rapidly reduced, milled and ground to a minimal, consistently fine quality where sub micron, nano particles can be produced.  

​

Using select, abrasive, hardened ceramic grinding media or stainless steel pulverising rings inside the 'DAC SpeedMill', products can be ground or milled to fine particle sizes.

​

DAC SpeedMill® vs Traditional Ball Mill

​

A traditional rotary ball mill is similar to a heavy duty washing machine with its drum set at 90 degrees. Spherical abrasive balls are placed into the sealed drum / chamber which is then rotated. As the drum rotates slowly round ceramic stones are lifted by the side walls then fall down to crush, grind and pulverise the product below into fine particles. As this 'ball mill' rotates the ceramic media move, grind together and fall creating friction, impact and collisions. This process gradually reduces the size of agglomerates (lumps) and the larger particles from what ever product is inside. Traditionally this takes hours to process and occurs at low speed. 

​

The DAC SpeedMill® works by a similar principle, adding a 'Hauschild spin' with unrivaled DAC power.

​

The original Hauschild SpeedMixer® is the most powerful materials mixer in the world - period. These will generate over 1000x gravity's force (g-force) and operate at up to 3500rpm.

​

You can appreciate that the DAC SpeedMill® process is far more intense and far quicker than any traditional method.

DAC SpeedMill® Ceramics

​

Productive Innovations supply two ranges of SpeedMill Ceramics, both offer profiles of cylinders or spheres. These ranges are manufactured from specifically selected hardened abrasive materials to offer maximum performance.

​

DAC SpeedMill Ceramic Cylinders are particularly effective due to their parallel sides mating to each other, maximising
contact area of the vertical sided Mix Cup walls.

The spheres will retain their position on the bottom of the Mix Cup processing the material as it is forced to move
and rotate inside the sealed Mix Cup.

​

How does a DAC SpeedMill® work?

​

Place the Pulverising Rings or Ceramic profiles in your chosen Hauschild Mix Cup. Cylinders should all be stood vertically for maximum particle abrasion and attrition. Add your chosen dispersant to wet grind your product in the DAC SpeedMill®.   

​

A) Apply the Mix Cup safety seal and close the screw top lid.

B) Cross check the total weight is within the SpeedMixers weight parameters.

C) Place the Mix Cup in an appropriate holder inside your SpeedMixer.

D) Select the mixing program - (RPM and cycle time).

E) Start the SpeedMixer.

​

Grinding or Milling Begins Immediately.

​

Nb: Monitor and regulate temperature during processing as high kinetic energy produces heat.
