Sigma Kneader

sigma kneaders, being our regular manufacturing machinery, capacities from 5 lits lab model to 6000 lits industrial production. They are fabricated as per user defined standards, specific to product applications. We manufacture specific kneaders meant for pigment and ink industry for manufacture of specialty pigments and flushed colours.

trough: the trough or sigma bowl is fabricated and bolted in construction. The trough is machined to close tolerance to minimize the clearance between the blades and the trough walls. This ensures thorough kneading of the material. The trough is provided with a mild steel jacket to circulate heat transfer medium and is generally capable to handle a pressure of 5 kg / sq. Cm. The trough is provided with a hinged lid with either light wt or heavy duty to suit vacuum service on request. 

sigma blades:  the blades are cast in one piece with integrated shaft. The shape and profile of the blade is derived to suit specific requirement so as to achieve optimum kneading results. The blades counter rotate at different speeds to ensure effective shear gradient.

drive assembly: a perfectly machined and robust housing is provided with a bearing housing, complete with a stuffing box to ensure vacuum service. The housing is capable to take dynamic loads and maintain a leak proof sealing. The stuffing box is provided with ports to circulate cooling media (water) to ensure gland cooling.

unloading arrangement: the trough is provided either with a hydraulic or mechanical motorised arrangement to tilt for unloading the mass effectively. However, the laboratory size machine is provided with manual tilting operation.

base frame: the base frame is fabricated from heavy steel sections and clad with m.s. Sheets. The base frame is provided with proper lug-supports with provision for proper foundation of the machine. The rugged design ensures the machine to withstand heavy static and dynamic loads.
