Battery Manufacturing EquipmentACEY-SF-1-500ML laboratory electrode-slurry filter
ACEY-SF-1-500ML is a benchtop SUS304 filter that screens up to 500 ml of electrode slurry before lab coating. It ships with 80, 100 and 150 mesh screens, finer screens are optional, and a small vacuum generator pulls the slurry through. It suits removing oversized particles from sample batches.

Match the screen to what should pass through
ACEY lists a 500 ml capacity, SUS304 construction and supplied screens of 80, 100 and 150 mesh. Finer optional screens are described as below 1000 mesh. Mesh numbers vary between standards, so ask for the screen standard, wire diameter, true aperture and the list of screens you will receive. The page also gives a 124 µm filtration figure without saying which screen it belongs to; ask ACEY to match it to a screen.
A screen holds back whatever cannot physically pass under the real flow conditions. Decide first what you want to catch. A harmful contaminant should be removed, while an active or conductive agglomerate is better broken up in the mixer. Measure both the filtrate and the solids caught on the screen, because losing part of your formulation can change how the electrode coats.

Ask how iron is removed
ACEY's description says the device removes large particles and iron impurities. The specification gives no magnetic circuit, no capture strength and no iron-removal test. Ask the manufacturer to name the actual mechanism and show a trial on deliberately contaminated slurry. Iron particles smaller than the screen aperture pass through a plain screen.
If iron is a concern in your project, state the particle type, size and concentration, and agree an analysis method for samples taken before and after filtering. Keep three questions apart: what the screen catches, what a magnet catches if one is fitted, and what the filter's own wetted parts might shed into the slurry.

Time the filtration and weigh the recovered slurry
ACEY lists an absolute vacuum of 65 kPa, an air-pump flow of 3 L/min and a power adapter for AC 220 V ±10%/50 Hz. Ask where and in what state the pressure is measured, and whether the pump suits your solvent. Pump airflow is a different quantity from slurry throughput. How long a high-solids paste takes to pass depends on its viscosity, so measure it.
The filter measures 145 × 150 × 200 mm and the air generator 140 × 70 × 150 mm, with a listed weight of 4 kg. Check the seals, screen support, cleaning access and solvent handling. Acceptance should record recovered slurry, elapsed time, screen blockage, caught solids and a coating sample made afterwards. Ask for a cleaning procedure that keeps cathode or anode residue out of the next formulation.
Agglomerates caught here would otherwise show up as streaks on the coated sample; the coating width page explains how to inspect it.

Questions that change the purchase
| Decision | What the catalogue says | Next step |
|---|---|---|
| What aperture is actually delivered? | The page lists 80, 100 and 150 mesh screens and a 124 µm figure without linking them. | Specify the screen standard and aperture and agree a retention test. |
| How is iron captured? | The page says iron impurities are removed but describes no magnet. | Get a written mechanism and before/after contamination measurements. |
| What slurry is recovered? | The page gives a 500 ml capacity and 3 L/min pump flow but no slurry throughput. | Measure recovery, caught solids, time and the coating that follows. |
Equipment questions
Can filtering replace adequate slurry mixing?
No. The device has no dispersion function. A screen can take out oversized material, but it leaves dispersion quality, formulation balance and dissolved impurities as they were. Fix agglomeration and contamination at the mixing stage, then use the filter as one sample-preparation step.
