Illite Ball Mill Air Classification System

D97 325–2500 mesh · 0.6–3.2 t/h

A verified Hebei project combined a Ø1.83 × 6.4 m ball mill with an AF200 air classifier to process illite feed below 10 mm across a reported D97 range of 325–2500 mesh at 0.6–3.2 t/h.

Processing Requirement

A Wide Adjustable D97 Range for Illite Powder

The project required illite feed below 10 mm to cover a reported D97 range from 325 to 2500 mesh, with capacity varying from 0.6 to 3.2 t/h.

A comparable project should define the priority product grade because finer cuts normally change circulation load, product recovery and achievable throughput.

Testing and Selection

Test the Mineral Before Scale-up

The reported values document one completed reference. A new process should be selected from representative testing because mineral source, moisture, hardness, feed distribution and required product cut can change the result.

01 · Material Review

Confirm Feed Properties

Review mineral composition, hardness, moisture, feed size, bulk density and contamination limits.

02 · Processing Test

Measure Fineness and Yield

Verify achievable distribution, oversize control, capacity trend, usable yield and product recovery.

03 · Scale-up Review

Select the Production System

Use the test result to select mill size, classifier arrangement, wear protection and collection system.

Ball mill and AF200 air classifier system for illite

Typical System Configuration

A comparable illite project can be evaluated around closed-circuit ball milling with AF200 air classification and controlled return of coarse material.

  • Feed preparation and metering
  • Closed-circuit ball milling
  • AF200 dynamic air classification
  • Coarse return to the mill
  • Qualified product collection
Typical system configuration only. The source record does not prove that every listed component was installed in the photographed project.

How to Read This Result

These values come from the authorized project record and describe this reference only. They are not a universal performance guarantee.

A new mineral should be tested before model selection because source variation, feed condition, operating settings and collection efficiency all affect capacity and particle size.
