Customer Challenge

Ultrafine Grinding of Low-Bulk-Density Graphite

The project required expanded graphite below 1 mm to reach D50 4–5 μm at a reported 40 kg/h.

Expanded graphite handling can be affected by low bulk density, difficult feeding and product collection. The process therefore needs to be evaluated as a complete system, not only as a grinding chamber.

Testing and Selection

Material Testing Before Equipment Configuration

The verified project parameters show the achieved reference result. A new production line should be selected from representative material tests, not from the reference values alone.

01 · Material Review

Confirm Feed and Chemistry

Review feed size, moisture, bulk density, hardness, purity limits and any oxidation or safety constraints.

02 · Grinding Test

Measure the Product

Test achievable fineness, capacity trend, product collection and the stability of the target particle size.

03 · Scale-up Review

Select the Production System

Use the test result to select the mill size, classifier setting, gas supply and downstream collection arrangement.

How to Read This Result

The values shown here come from the supplied project record and are not a universal performance guarantee. Throughput and particle size change with feed properties, operating settings, gas conditions and the collection system.

For a new material, Mills Powder should reproduce the target through a laboratory or pilot test before confirming a commercial configuration.
