Blowers, Compressors and Controls

ROOTS rotary positive blowers. For variable pressures with constant volumes, at pressures from 1 to 20 PSIG (69 to 1,379 mbar), flows from 2 to 40,000 cfm (3.4 to 67,960 m3/hr) and vacuums up to 28″ Hg (948 mbar).
ROOTS centrifugal compressors. For constant pressures and variable volumes at pressures to 50 PSIG (3,447 mbar) and capacities from 4,000 to 300,000 cfm (6,796 to 509,703 m3/hr).
Some Applications by Industry:
- Aluminum: Pneumatic conveying of bauxite powder from barge to storage; separating aluminum and sand particles by flotation on air.
- Carbon Black: Pneumatic conveying and bagging; combustion air.
- Cement: Air supply to homogenize bulk cement going into storage bins; fluidizing cement for conveying in batch plant; conveying from truck to storage bins; air slide for bulk cement transport trucks, conveying ready-mixed concrete batch plant to trucks.
- Conveying: Pneumatic, vacuum, or combinations for materials such as: sands, feeds, cement, salts, coal, cereal, fly ash, gypsum, bauxite, flour, grains, sugar, starch, carbon black; transfer materials from railroad cars, trucks, ships to vats, hoppers and bins.
- Dairies: Pressurizing tanks or trucks; evaporation for drying milk; aeration of milk wastes; gentle aeration in bulk storage to prevent butter fat separation; vacuum for milking machines.
- Food Processing: Freeze drying; evacuation of air from bottle or can filling machine; agitation; pneumatic conveying.
- Gas and Oil Fields: Field repressurization from exhaust gases of gas engines.
- Glass: Pneumatic conveying; vacuum holding of sheet glass for transfer; evacuation of test chamber; vacuum filtration from grinding and cutting particles; air cooling sheets and molds; blowing water from glass sheets; cooling and tempering air for curved windshields leaving molds.
- Oil Refineries: Asphalt blowing; fly ash conveying; liquid transfer by air pressure; vacuum flashing; pneumatic conveying.
- Paper Mills: Paper machine vacuum; head box pressurization; pneumatic conveying; waste treatment aeration; paper folding; vacuum pick-up of sheets; air glide or cushion for moving heavy loads on flat surfaces; vacuum cleaning/conditioning of felts; roll heading for wrapping; black liquor recovery.
- Sewage: Aeration in activated sludge plants — industrial, municipal, commercial (hotels/motels/sub-divisions/ships, etc.); separation of grit from sewage; grit channel aeration (prevents settling of grit); pneumatic conveying; dewatering sludge on vacuum filters; recirculation of sludge gas; cake blowing; combustion air for incineration.
- Steel Mills: Blast furnace air supply; combustion air for open hearth furnace; oxygen furnace; Bessemer converter; cupola blowers; coke oven exhauster; fly ash collectors; vacuum filtration, agitation of ferrous sulphate.
- Sugar: Pneumatic conveying; aeration of storage bins; vacuum filtration.
