FRACCAROLI AND BALZAN COMPACT
Fraccaroli and Balzan (F&B) manufacturer the most cost-effective, simple to use solids separators available to the Stone Industry today. These units are capable of efficiently separating stone particulate from the water used in any stone processing application from sawing to CNC edge profiling.
Reclaiming and recycling process water will greatly cut production costs to any operation and easily pay for itself in most applications just months. The F&B units employ an ingenious combination of a low-cost flocculent and simple mechanical filter press to “clean” water that can be recycled back through CNC spindles.
Cycle Description
Wastewater coming from the stone processing plant is collected in a pit or tank where a float actuated submersed pump automatically pumps the slurry into the cylindrical decant tank. Before reaching the tank, a flocculant (settling agent) is automatically injected into the slurry. The chemical action of the flocculant accelerates the suspended solid particles “falling” out of suspension. The treated slurry is pumped into the decant tank in a way that minimizes turbulence to further facilitate the efficient separation process.
The “clean” water flows to the top of the decant tank over-flowing into a surrounding chamber while the heavier solids collect in the bottom of the decant tank. The treated water is pumped from the “clean water chamber” back to the processing machine by a centrifugal pump. The mud collected in the bottom of the decant tank is discharged into a filter press where the water is finally filtered.

Clean20
|
CLEAN 20Every stone grinding application produces
particles that enter into the recalculating water loop. When these particles
are allowed to circulate through the system, a number of conditions occur
that adversely affect production efficiency. Water consumption increases.
Diamond wheel life and performance decrease. Labor costs increase due to
time spent unclogging water lines, removing “mud” from water tanks and
especially the “dead-time” when productions is stopped while rectifying
these conditions. The hidden cost to a typical operation is directly
proportional to the number of grinding machines used and can range from
thousands of dollars to tens of thousands of dollars per year.
Dealing with stone particulate has made the
transition from a necessary nuisance to a viable way to increase shop or
plant efficiency. The Clean 20 is a simple, affordable, effective way to
remove stone particulate from process water. It is inexpensive to purchase,
install and operate. The Clean 20 is also economical in size allowing it to
be used in the smallest of shops or strategically deployed throughout the
largest of plants..
Cycle Description
The separation process is quite interesting and
is an ingenious concert of gravity and fluid dynamics with a little
flocculent to speed things along. Process water laden with stone particles
flows into the unit where a dosing pump precisely meters a very small amount
of flocculent into the stream. This mixture of water and flocculent are
blended by an in-line static mixer. This mixture empties into a secondary
chamber for final blending and then to the main chamber in laminar flow.
Laminar flow is the movement of water without turbulence. This is critical
because any disturbance would impede the efficiency of the settling process.
At this point, the suspended particles begin to agglomerate into small
“seeds” which gradually grow into a size where they rapidly drop out of
suspension into the collection cone. As this settling process continues, the
weight of the agglomerated particles and water naturally apply pressure
condensing the solids building in the bottom of the collection cone into a
progressively denser wet mass. At a preset time, a pneumatic valve empties
the solids into a porous collection bag. Subsequent discharges continue to
compact the solids and squeeze out the residual water. When the bag is full
and completely drained, it is off-loaded for proper disposal.
