Powder addition behavior
Record how quickly the powder wets, whether it floats or clumps, and how the liquid changes during addition.
Pre-mix equipment / High-speed dispersion
High-Speed Disperser for a controlled wet-out stage.
Build the equipment brief around how powders enter the liquid, how the batch changes, and what condition must leave the disperser.
A disperser is a process stage—not an isolated motor, shaft and disc.

Choose by process duty
Start with the batch sequence, not a drive label.
The same product name can describe very different duties. Define what enters, what changes during addition and what “ready” means before discussing the equipment arrangement.
Vessel and disc relationship
Treat liquid level, vessel geometry and dispersing-element position as one circulation question.
Batch endpoint
Define the observable condition that releases the batch to milling, final blending or transfer.
Typical process position
Prepare a consistent feed for what comes next.
High-speed dispersion is often the bridge between raw-material addition and a downstream refinement or finishing step.
01→
Charge liquids
Set the starting liquid phase and the addition sequence.
02→
Wet out powders
Introduce solids while maintaining useful circulation through the batch.
03→
Develop dispersion
Continue until the agreed pre-dispersion condition is reached.
04
Transfer with intent
Send the batch to wet grinding, let-down or holding without losing the process state.
Disperser process brief
Bring the information that changes the wet-out route.
This checklist keeps the discussion focused on the material and sequence instead of guessing at an equipment configuration.

Equipment questions
High-speed disperser selection starts with four questions.
When is a high-speed disperser different from a general mixer?
A high-speed disperser is selected for a dispersion duty such as powder wet-out and agglomerate breakdown. A general mixer may be selected mainly for circulation, blending or suspension. The required batch result should decide the equipment category.
Why does vessel geometry matter to a disperser brief?
The vessel, liquid level, disc position and batch rheology influence how material circulates through the active zone. Describing only the drive leaves out much of the process context.
Can a disperser prepare feed for a bead mill?
Yes, pre-dispersion can be an upstream stage for wet grinding. The required feed condition should be agreed from the bead-mill route rather than assumed from the disperser alone.
What should be included in a high-speed disperser RFQ?
Include the formula behavior, solids content, viscosity change, addition sequence, batch objective, vessel context, transfer destination, cleaning method and available utilities.
