Double-Shaft Mixing Kettle/Reactor

Double-Shaft Mixing Reactor/Kettle

Highlights

Dual-Shaft Dissolver & Scraper Agitation System
Handles Mid-Viscosity Materials 10,000-50,000 cps
Scales from 1000L - 12,000L Capacity Range

ATEX, CE, and ISO Certified Equipment Design
Inverter-driven Speed Control on both Shafts
Bridge or Flange Tank Mounting Configurations

MachineValley's Double Shaft Mixing Reactor/Kettle runs two shafts in one tank: a dissolver disc up to 1440 rpm for breaking down pigment and agglomerates, and a slower scraper that sweeps the wall and base the whole time it's running. On bigger batches especially, that second shaft is the difference between an even mix and a ring of unmixed material stuck to the sides.

Major Benefits

Scraper Stops Material Sticking to Wall
Dual-Shaft cuts total Mixing Time
One Machine, Pilot to full Production
Even Heat Transfer via Jacket + Scraper
Less manual Cleaning between Batches

Major Feature

Dissolver + Scraper Dual-Shaft Agitation
Inverter speed control, both shafts
Jacketed tank for Heating or Cooling
Bridge or Flange Tank Mounting for Reactor
Robust Steel Construction in SS304/SS316

Machine Options

MVD500

500 Litre Double Shaft Mixing Kettle

Compact configuration built for small-batch and pilot production runs. Pairs a dissolver disc with a scraper shaft in a jacketed vessel, sized for labs, R&D trials, and low-volume production of paints, inks, and coatings before scaling up.

MVD1000

1000 Litre Double Shaft Mixing Kettle

This reactor uses dissolver and scraper shafts working together in a single tank, suited for small-to-mid production batches. Common entry point for facilities moving from lab-scale to regular production runs.

MVD2000

2000 Litre Double Shaft Mixing Kettle

Steps up to capacity range, with higher dissolver and scraper power to keep mixing consistent as batch size grows. A common choice for mid-size manufacturers running regular production cycles of emulsion paint, ink, or pigment dispersions.

MVD5000

5000 Litre Double Shaft Mixing Kettle

Production-scale configuration, built for continuous, high-volume operation. Delivers stronger dissolver shear and scraper coverage across a larger vessel, keeping wall buildup and dead zones under control even at this size.
