Battery Manufacturing EquipmentACEY-PVM-5L planetary dispersion slurry mixer
ACEY-PVM-5L is a vacuum planetary mixer for electrode slurry. Two slow stirring shafts, a 0–6000 rpm dispersing disc and a wall scraper work in a water-jacketed SUS304 vessel with hydraulic lift. The table lists 2L effective volume despite the 5L name, so confirm the vessel size before planning batches.

Three motions, each with its own speed reference
ACEY lists one dispersing shaft, two stirring shafts and a wall scraper. Planetary revolution runs at 0–50 rpm measured against the ground. Stirring runs at 0–80 rpm measured against the planetary box, which equals 0–130 rpm measured against the ground. Both figures describe the same motion from two reference points. The disperser runs separately at 0–6000 rpm with a 55 mm disc.
The mixing and revolution drive is 1.5 kW and the dispersion drive is 2.2 kW. Ask which speeds you can set independently and which combinations are allowed at your slurry viscosity. Particle-size results come from your recipe as well as the disperser speed, so specify the powder wetting sequence and the slurry measurements you will accept.

Vessel volume: 5L name, 2L effective
The product and model names say 5L. The table gives an '08L' design volume and a 2L effective volume, with a vessel of 240 mm diameter × 180 mm. Ask ACEY whether this is a misprint or a different vessel option, and request a vessel drawing, the nameplate or configuration sheet, and a demonstrated minimum and maximum working fill.
Wetted parts are SUS304. A G1/2 ball valve sits at the bottom for discharge, and the water jacket has G3/8 ports. Ask which seals and scraper material are fitted, how much slurry the valve recovers, and how the vessel is opened for cleaning with your solvent and powder. Check compatibility and cross-contamination against your formulation, since stainless steel is only part of the wetted surface.

Vacuum and temperature limits for real use
The vacuum entry is printed as '≤−0.098mPa', where the capitals and reference are unclear. The page names a 2XZ-2 pump with a buffer tank. Ask for the correct pressure unit, the gauge reference and location, and the leak-test method. ACEY also states a 24-hour vacuum hold and no oil leakage; agree the test conditions for both, and check solvent safety and contamination on your own slurry.
A temperature sensor near the vessel bottom or wall reads from 0 to 300°C. That is the display range. Ask for the highest process temperature the seals and drives allow. The jacket takes heating or cooling water, so agree coolant flow, seal limits and the thermal trip response, then check them in a loaded trial. Power is 380 V/50 Hz three-phase, and a separate 0.37 kW motor drives the hydraulic lift.
ACEY's profile lists the lab coaters that take this slurry next. The coating width page covers what to measure on the coated sample.

Questions that change the purchase
| Decision | What the catalogue says | Next step |
|---|---|---|
| What vessel is actually delivered? | The model says 5L; the table gives an '08L' design volume and 2L effective volume. | Get the vessel drawing and working fill in writing before quoting batch output. |
| Which speed reference is being used? | Stirring is 0–80 rpm against the planetary box or 0–130 rpm against the ground. | Set recipe values with their reference frame and confirm which drives are independent. |
| Are vacuum and temperature limits clear? | The page prints '≤−0.098mPa' and a 0–300°C sensor range. | Agree operating limits and run a loaded thermal and vacuum trial. |
Equipment questions
What makes a useful electrode-slurry acceptance run?
For acceptance, use the agreed vessel, working fill, formulation and addition sequence. Record viscosity by a named method, agglomerates, solids distribution, temperature rise, vacuum behaviour and recovered mass. Check lift positioning and cleaning access. A slurry that looks well mixed, or a vacuum hold on an empty vessel, tells you too little; measure the slurry against your coating needs.
