Dried Kieselguhr Air Classification

400/800 mesh · 2 t/h

A verified Jilin project used two AF200 air classifiers to process dried kieselguhr feed with 325 mesh oversize at or below 8% into two reported products: 400 mesh at 99% and 800 mesh at 95%, at 2 t/h.

Processing Requirement

Two Product Cuts from One Dried Kieselguhr Feed

The project required dried kieselguhr feed with 325 mesh oversize at or below 8% to be separated into reported 400 mesh (99%) and 800 mesh (95%) products at 2 t/h.

A comparable classification project should verify feed moisture, bulk density, agglomeration, inlet distribution, required cut points and recovery for each product stream.

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.

Equipment Selection

Dual AF200 Air Classification System

Dual AF200 air classifier system for dried kieselguhr

Typical System Configuration

A comparable kieselguhr project can be evaluated around staged AF200 air classification with controlled feeding and separate collection for each qualified product.

  • Dried feed conditioning and metering
  • Primary AF200 air classification
  • Secondary AF200 air classification
  • Separate product collection
  • Fine-dust filtration and recovery
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.
