The ground fine samples are measured with the wet dispersion unit. The wet measured samples are pre-dispersed in aqueous 0.1% sodium hexamethaphosphate solution (NaPO 3) 6 and subjected to 2 min of external ultrasound (200 W) before they are fed into the sample storage tank of the instrument. The evaluation software model used is Mie theory.

The Zeta ® grinding system is, in every respect, a user friendly, low-maintenance and very reliable grinding system. Starting with the structural design of the agitator mill, there is already a number of advantages: the horizontal orientation guarantees a homogeneous fill of the grinding media in the grinding tank.
For high viscosity products, the HCPS Immersion Mill with Sweep is truly the world's most versatile mill, using a separately driven sweep blade to ensure consistent product feed to the mill. This mill is designed to process …
factory dispersion using 100 grams of sulphur, 100 ml. of water and 2 grams of dispersing agent. In all cases it was found necessary to add more water at the end of the run to remove the dispersion sticking to the pebbles. This amount varied from 25 to 175 ml. The pebble mill was a common type laboratory jar mill with a volume of 0.24 cubic feet.
The actual dispersion system in a bead mill consists of a milling chamber and an agitator; the milling chamber is filled with the grinding beads (material e.g. glass, zircon oxide, steel) and the product to be dispersed. In the milling vessel, the grinding medium is kept moving by the agitator, which itself is driven by a motor.
Driven by innovation, the Hockmeyer Equipment Corporation has been a leading provider of wet grinding and dispersion process solutions for over 80 years. The company is an entrepreneurial team of people who share common values and goals: Communication, Conviction, Commitment and Courage. Companies around the world trust machines designed …
4. Avoid other additives in the dispersion phase (e.g. thixotropes) as they may interfere with the efficiency of the Solsperse hyperdispersant in its dispersion of the pigment. 5. In general, use a low amount of resin in the dispersion (maximum of 10%) to try to minimize the competition between the resin and the
High Shear Mixer Products Engineered to Deliver. Our product line consists of high shear homogenizer & wet mills, inline powder dispersers, inline continuous processers, inline emulsifier mixers and in-tank mixers.. Inline Powder Disperser. Quadro Ytron ® ZC - High shear single-pass disperser designed for the most difficult-to-wet powders, thickening agents, and rheology …
Wet milling, also known as wet grinding, is a process through which particles that are suspended in a liquid slurry are dispersed in that liquid by shearing or crushing. Once the milling process is complete, these particles are ready for use or can be dried and separated for incorporation into additional products. Wet milling is more complex ...
Pigment dispersion can be a challenging process during the production of paints, coatings, and inks. Waterborne systems are particularly challenging due to environmental regulations, demand for premium color coatings, and cost considerations. Moreover, the quality of the dry paint film or ink is very much related to the uniformity of the distribution of the pigment.
The "basket" style media mill has been the salvation of small batch, rapid changeover industries, such as the ink dispersion business. And the CMC Batch Mill line is a great example of this milling platform.
