Stationery Dissolvers PVD |
| |
The most advanced construction of stationary Dissolvers, equipped with a centrally
driven dispersing disc and an anchor agitator with scraper - a versatile machine,
perfect for diffi cult dispersion products. |
| |
|
|
Due to its unique solution
of penetrating shafts of disc
and scraper agitators, the
disc rotates in the vessel
axis therefore providing
remarkable process results. |

 OPERATION: |
|
| |
The dissolver is equipped with disc and anchor agitators; the anchor is equipped with
a scraper. The disc agitator is used for product dispersion, whereas the anchor agitator ensures the mixing and transfer of the product inside the vessel and facilitates vessel discharging and cleaning.
The dissolver features a unique solution of concentric shafts: the disc agitator shaft, located centrally, penetrates through the anchor agitator shaft which enables the use
of large diameter disks and attaining the high tangential velocity of disks.
This results in remarkable dispersion effects. Such a design significantly decreases the duration of the expensive grinding process in many paint manufacturing technologies.
The agitators and shafts, as well as the fixing parts, are made of stainless steel. The agitators are driven independently by two electric motors, both driven by frequency inverters for speed variation.
The disc agitator motor may be equipped with an automatic RPM rotational speed control system which optimizes rotational speed and motor power.
The PVD Dissolvers - PVD/H series - can be optionally equipped with a dispersion unit lifting system, which results in:
. better incorporation and dispersion,
. possibility of adjusting disc position to specific process requirements,
. possibility of mixing (finishing) at low disc revs without the destruction of dispersive resin - for waterbased products. |

| APPLICATION: |
|
| |
The PVD Dissolvers are used for the production of:
• coatings,
• concentrated pastes (even concentrated solvent based pastes),
• bases,
• plasters,
• adhesives,
• putties.
The PVD Dissolvers equipped with a dispersing disc only are used as for emulsion making or dissolvers for coatings of low viscosity. |
