The area between the Gate – type Agitator & reactor wall is very small which is propitious to heat transfer. During quick rotations, the quiescent layer will be brought down from the reactor wall by the liquids driven by the agitator blade, during slow rotations, agitator with scrapper blades have better heat conduction performance. Such agitators are usually used for heat transfer operation, crystallization, agitation of highly viscous slurries & settling slurries
This set – up consists of two shafts viz., one solid & the other hollow. The solid shaft has multiple paddle blades which rotate clockwise whereas the hollow shaft is provided with anchor scrapper blades rotates anticlockwise direction. Homogenous mixing of products is achieved by the virtue of contra rotary motion of two different types
of blades & high speed homogenizer. Additional arrangement like vacuum jacketed mixers with vacuum pump, heating arrangement is made on clients request.
Applications: this product is suitable for highly viscous & highly dense materials. It is used in industries where mixing or blending of materials like toothpaste, grease, etc is required
High Speed Disc Agitators:
This has a disc with corrugations. The speed of the agitator provides sufficient centrifugal force through surface friction to generate a flow. It produces high shear & helps disintegration of low density fibrous solids.
Zero Leakage Magnetic Stirrer Drive:
The autoclaves can be equipped with glandless high-pressure rotary stirrers with integrated magnetic couplings. Stirrer drive: the drive of the stirrer is adjustable. The stirring speed of the DC motors is remote – adjusted from the electric control box Speed Indication: display of the stirrer shaft speed is achieved by a digital instrument mounted on the control box. Stirrer shaft speed is measured by an inductive sensor which takes its measurement by an indication magnet mounted on the stirrer shaft.
Propeller Agitator:
A propeller agitator is shaped with a tapering blade to minimise the effect of centrifugal force & to produce a maximum axial flow. It may be mounted centrally, off centre or at an angle to the tank.
Radial Propeller Agitators:
It has blades fixed at the mid & at the end of a rotating arm. The blades are pitched to the direction of rotation. By varying the height, width & angle of pitch, turbulence & shear can be controlled.
