| OBJECT: |
Electrostatic copier "ink" (powder). Fast wet-out and thorough dispersion of powders prior to spray drying. 70% solids loading includes: Carbon Black, iron oxide and silicates.
|
|
PROBLEM:
|
Abrasive wear, plus high viscosity and specific gravity. Other mixer brands tested could not maintain wet out and flow to completion of mix cycle. |
|
RESULT:
|
Excellent dispersion and improved spray dry results - plus improved product performance in copying machines. Also, less mixing time than "sawtooth blades". |
|
AB MIXER:
|
C-3-1 mixer in 300 gallon tank. Mixer equipped with bronze mixing head bearing.
|
|
EQUIPMENT REPLACED:
|
User retained "sawtooth blade", but shifted production to AB mixer. |
