Agitator & Mixer Gearboxes

High-torque worm and helical drives for industrial agitators and mixers — vertical and horizontal mounting for cement, chemical, and process plants.

Anand Gears vertical worm gearbox for agitator and mixer drives

Process Industry

Drives for Agitators, Mixers, and Blenders

Cement additive tanks, chemical reactors, and slurry mixers need slow, high-torque shafts that survive dust, vapour, and long campaigns. Anand Gears supplies cast iron worm gearboxes (50–305CD, ratios 5:1–100:1) and helical reducers for agitator service — including vertical-up and vertical-down mountings, Adaptable hollow-input variants, and self-locking high-ratio holds for batch vessels.

Worm for compact right-angle high torque; helical for higher efficiency continuous duty
Vertical-up / vertical-down and Top-Bottom orientations
Self-locking high ratios for batch hold without a brake
Cast iron preferred for thermal mass in continuous mixing
Double output options for dual-impeller or dual-shaft mixers
Dust-conscious sealing for cement plant environments

Sectors

Where These Drives Run

Cement & construction chemicals

Additive tanks, slurry mixers, and batch blenders near dusty plant floors — cast iron housings and sealed bearing cavities.

Chemical process

Reactor agitators and dissolvers with continuous or long-batch duty; specify seals and lubricant grade for the process environment.

Water & effluent

Flocculator and mixer drives with outdoor duty and weather considerations.

Food & pharma (with options)

Where washdown applies, discuss stainless or coated options and food-grade lubricants.

FAQ

Agitator & Mixer Gearboxes — Common Questions

Worm or helical for my mixer?

Use worm when you need compact right-angle layout, high ratio, or self-locking hold. Use helical when continuous efficiency and thermal performance dominate at moderate ratios.

Can you supply double output for dual impellers?

Yes. Double-output shaft worm gearboxes are a standing special configuration for dual-shaft and dual-side drives.

What mounting orientations are available?

Foot, flange, vertical-up, vertical-down, Under Driven, Over Driven, and Top-Bottom arrangements — confirmed against lubrication design for each case.

Size an Agitator Drive

Send impeller torque or motor kW, shaft speed, mounting (vertical up/down), and process fluid notes. We recommend CD, ratio, and housing material.
