Fine Chemical Case Study

Ammonium Polyphosphate Impact Milling

20 μm · 500–800 kg/h

A verified Shandong project used a CR1000 superfine impact mill to process ammonium polyphosphate below 10 mm into a reported 20 μm product at 500–800 kg/h.

Processing Requirement

Production-Scale Fine Milling of a Flame-Retardant Powder

The project required ammonium polyphosphate feed below 10 mm to reach a reported 20 μm product at 500–800 kg/h.

A comparable project should test moisture, thermal response, dispersibility, dust behavior and product recovery before confirming classifier settings and capacity.

Testing and Selection

Test the Chemical Powder Before Scale-up

The reported values document one completed reference. A new process should be selected from representative testing because feed condition, thermal sensitivity, moisture, dispersibility and collection behavior can change the result.

01 · Material Review

Confirm Feed Properties

Review feed size, moisture, bulk density, thermal sensitivity, dust behavior and acceptable contamination.

02 · Milling Test

Measure Fineness and Yield

Verify achievable particle size, capacity trend, temperature rise, product recovery and dispersion.

03 · Scale-up Review

Select the Production System

Use the test result to select mill size, classifier settings, contact materials, safety controls and collection arrangement.

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 material should be tested before model selection because feed condition, operating settings, temperature limits and collection efficiency all affect capacity and particle size.
