Stationary Basket Mills PSB |
| |
PSB Stationary Mills are designed for the grinding of pigments pastes or other
substances in mobile vessels. Stationary, colled basket enables use of mobile vessel,
even without cooling jacket. |
|
Maintenance and cleaning
operations are reduced to
a strict minimum. |
| |
|
 OPERATION: |
|
| |
The mill consists of a rotating disc fixed on a vertical shaft inside a stationary basket. The basket assembly, immersed into the mobile vessel, is filled with appropriate milling beads.
By the disc rotation, the beads are accelerated and produce tremendous friction and shear effect, dispersing and milling the particles in suspension in the millbase passing through the basket.
The bottom of the basket, made of slotted bars, separates the beads from the product, which is pumped out by an impeller situated below the separator, and actuated by the same vertical shaft.
This impeller by its axial / radial pumping effect, creates the circulation of the product in the vessel and its transfer into the milling basket.
The temperature of the millbase is controlled by removing the excess of heat with the efficient cooling jacket of the basket; cooling of the vessel is not required.

| APPLICATION: |
|
| |
PSB Mills are used in the dispersion and milling process of:
. coatings,
. enamels,
. microbiological products,
. cosmetics,
. dispersion of pharmaceuticals,
. chocolate,
. dispersion of paper coatings,
. lubricant additives.
Absence of pumps, pipes, transfer vessels, makes the PSB mill the ideal tool for high quality results with small and medium size batches, when formulation or colour changes are frequent or when operation is periodical. |
