| Mix vessel
One (1) cone-bottom polyethylene tank, nominal capacity
= 15 gal
Recirculating pump
One (1) 1.5 HP centrifugal pump. ChemIndustrial's standard
3500 RPM horizontal water pump running at a working
point of 24 gpm at 95 feet of head. This was the working
point that resulted from using that particular pump
with the arranged recirculation path.
Separator
One (1) ChemIndustrial 3" diameter hydrocyclone
with two body segments, 3/4" adjustable top outlet
(adjusted to 4.0" from the inside of the hydrocyclone
cap) and 1" bottom outlet
Hoses
#1: Mix vessel bottom outlet to pump inlet at 1"
#2: Pump discharge to Hydrocyclone inlet at 1"
#3: Hydrocyclone top outlet to mix vessel lid opening
at 1"
#4: Hydrocyclone bottom outlet to mix vessel lid opening
at 1"
Arrangement
The hydrocyclone was mounted vertically above the mix
vessel. The discharge from Hose 3 and Hose 4 was available
for visual inspection and sampling at the mix vessel
lid opening.
Iron powder
Hoeganaes Corporation Ancor 80SC150 iron sponge powder
(particle size distribution 100%, <150 microns)
Iron powder/water mixture
2 pounds of the powder mixed into 6 gallons of water
in the cone-bottom mix vessel. The material was added
while water recirculation was underway and was mixed
uniformly due to the high recirculating rate.
Valves
Full port ball valves were available at hoses 1, 3 and
4. In practice, all valves except the one in hose 4
were wide open during the test. The valve in hose 4
was used to throttle flow. |
