| MIXING/BLENDING CIRCULATORS FOR INDUSTRY | Back to Standard Products and Spare Parts |
The "jet" action of these lightweight, low-cost circulators provides mixing and circulation of liquids in open
or closed tanks.
Croll-Reynolds mixing/blending circulators provide effective mixing and blending to fill a wide range of needs in the process industries or wherever liquids are stored or handled. They may be used for tank turnover, blending dissimilar liquids, solid suspension or aeration. Liquids and slurries of various viscosities, densities and types can be thoroughly mixed and kept in suspension. Dissimilar liquids may be effectively blended while particles are held in suspension. Croll-Reynolds circulators operate on the principle of the Company’s patented jet ejectors. The basic difference is that instead of gases, the motivating and suction fluids are liquids or slurries. HOW THEY WORK The venturi-shaped circulator is immersed in the fluid to be mixed or circulated (Fig. 1). High pressure motive fluid is usually provided by a small pump recirculating a portion of the tank’s content. Mixing is achieved by the “jet” action of the circulator. High-pressure motive liquid entrains the surrounding liquid, which enters through open inlet ports. The two liquids are thoroughly mixed then discharged, creating a discharge “plume” or pattern which accomplishes additional circulation. AVAILABLE SIZES Standard Croll-Reynolds circulators are available in sizes ranging from 17 gpm, 1” NPT, to 900 gpm, 6” 150 lb.) flange, (see photo) . Typical entrainment ratio is 3:1. Custom designs are available with varying sizes, ratios, and materials of construction. CONFIGURATING AND POSITIONING The circulating/mixing efficiency of a Croll-Reynolds circulator depends on both the "jet" mixing action, the circulator’s position in the vessel and the angle of discharge. Where tank size, shape and discharge plume characteristics require, multiple units can be used; their overlapping patterns minimize stagnant areas. When positioning a Croll-Reynolds circulator in a tank, these general rules should be followed:
