Mixing-tank geometry / Vortex-control decision
Baffles are one way—not the only way—to interrupt non-target tangential rotation. A controlled surface vortex may belong to a powder-addition route, while another duty may need stronger top-to-bottom circulation. Compare the exact stage, material and vessel topology before choosing either arrangement.
Keep the flow question specific
The page owns one decision: how a candidate tank prevents or manages unwanted whole-batch tangential rotation. It does not replace agitator selection, powder-addition design or the complete mixing-tank RFQ.
State whether the stage needs blending, suspension, heat-transfer support, wall movement, surface addition or another defined duty. Record when a surface vortex is intentional and when batch-scale circular motion is the problem being reviewed.
A supplier may propose wall baffles, a different shaft position or angle, tank shape, or another internal element that changes bulk rotation. Require the exact candidate drawing and process basis; do not turn any named example into a universal design rule.
Rheology, working level and duty can change during charging, mixing, temperature adjustment and discharge. A topology that serves one stage is not automatically approved for the entire batch sequence.
Topology comparison
These columns organize supplier questions; they do not prescribe a baffle or rank the two routes. Keep the base geometry and process conditions equivalent when isolating the baffle effect, or disclose every topology difference when comparing complete systems.
Swipe or scroll horizontally to review every evidence column.
| Review row | Baffled candidate | Unbaffled or alternative topology | Approval record |
|---|---|---|---|
| Intended fluid motion | The supplier identifies the non-target rotation to be interrupted and the circulation required for each process stage. | The supplier explains why no wall baffle is proposed and how mounting, vessel shape or another stated element manages—or deliberately preserves—the required motion. | Duty by stage, acceptable surface behavior, circulation or suspension observations, air or foam concern and unresolved questions. |
| Vessel and mounting | Record vessel shape, bottom, working levels, shaft position, impeller and the exact baffle count, form, position, gaps, attachment and removability proposed by the supplier. | Record the same base vessel and impeller details plus any offset, angle, orientation, non-cylindrical shape, frame element or other anti-rotation feature. | Controlled drawing, dimensions and revision; identify the single intended test difference or disclose the complete set of geometry changes. |
| Changing batch | Review the proposed baffle action as fill level, rheology, solids state, temperature and duty change through the sequence. | Review whether the alternative arrangement has the same purpose at low- and high-rheology stages and during minimum, normal and maximum working quantities. | Material supplier and lot, batch sequence, working quantity, stage observations, sample identities, deviations and disposition. |
| Internals and interfaces | Check baffle clearance and interaction with coils, dip pipes, feed points, sensors, covers, shaft removal, discharge and inspection access. | Check the same interfaces against the proposed shaft orientation, tank corners, frame element or other topology-specific internal path. | Reviewed general arrangement, interference register, thermal and transfer interfaces, access method, owner and open actions. |
| Recovery and cleaning | Map product hold-up, surfaces behind or beneath baffles, attachment points, drainage, inspection, removal if proposed and the cleaning sequence. | Map residue and access around corners, angled shafts, frame elements or other features; unbaffled does not automatically mean clean or drainable. | Same recovery, cleaning chemistry, sequence, inspection points, residue-release method and failed-clean response for both candidates. |
| Trial and release | Trial the stated baffle arrangement with the controlled material, base geometry, impeller, level, sequence and acceptance method. | Trial the exact alternative arrangement on the same basis; if more than the baffle state changes, release only the complete tested topology. | Same endpoint and method, representative batch evidence, cleaning release, supplier confirmations, exclusions and change-control triggers. |
Decision route
Preserve the buyer-controlled material and acceptance basis. Let each candidate supplier define the exact geometry, then verify the complete route without turning another manufacturer's example into a design prescription.
Describe the process duty, when it occurs, what fluid motion is useful and whether a controlled surface vortex is part of the intended addition route.
Use the same material supplier and lot, working quantity, base tank geometry, impeller, mounting, sequence, endpoint method and cleaning-release basis when isolating the baffle state.
Request a revision-controlled drawing and review baffles or alternatives, changing rheology, working levels, internals, heat-transfer surfaces, discharge, access and cleaning together.
Run representative conditions, record surface and bulk behavior by stage, sample against the shared endpoint, verify recovery and cleaning, and obtain candidate-supplier confirmation before release.

These are review fields, not universal baffle dimensions or operating values. Keep unknowns assigned to a responsible reviewer and verification action.
Open the process briefFormula reference, material identities, supplier and lot, composition or solids basis, relevant rheology, temperature sensitivity, settling, air or foam behavior and restrictions.
Charge order, working quantities, viscosity or rheology changes, blending, suspension, heat-transfer support, surface addition, hold and discharge duties with the intended motion for each stage.
Tank shape and dimensions, bottom, working levels, headspace, cover, discharge, existing internals and the controlled geometry that must remain equivalent in the comparison.
Impeller identity and revision, shaft position and orientation, stages, direction, location through the working range, drive boundary and supplier drawing reference.
Supplier-proposed baffle count, form, position, gaps, attachment and removability—or the exact offset, angled, shaped-vessel, frame-element or other alternative—with no assumed rule-of-thumb dimensions.

Normal drain and recovery path, residue locations, cleaning chemistry and sequence, access or removal, inspection and sampling points, release method and failed-clean response.
Same endpoint and method, representative material and batch, stage observations, samples, deviations, supplier confirmations, exclusions, open items and change-control triggers.

Buyer decision FAQ
No universal requirement is established here. Start with the intended fluid motion, material and rheology by stage, vessel geometry, working levels, impeller and mounting. Ask the candidate supplier to explain and verify the exact baffled or alternative topology.
No. Separate unwanted whole-batch tangential rotation from a deliberately controlled surface vortex used by an approved process route. The powder-addition decision must remain attached to the vessel, mixer, material and trial evidence.
This guide publishes no universal count, width, gap, length, angle, offset or vessel ratio. The supplier must define the candidate geometry from the actual process and show it on a revision-controlled drawing for engineering review and representative testing.
It can be a candidate arrangement, not an automatic substitute. ProQuip and INDCO describe manufacturer-specific examples, while the Liquiverter and EKATO sources show other named topologies. Review the complete geometry, duty, internals, mechanical loads, access, cleaning and trial result with the responsible supplier.
Include the controlled material supplier and lot, batch sequence, changing rheology, working quantities, intended motion by stage, base vessel geometry, impeller and mounting, exact baffle or alternative topology, internal interfaces, recovery and cleaning basis, shared endpoint method, representative trial, supplier confirmations, exclusions and change triggers.
