WFJ Series Fine Pulverizer for Pharmaceutical Powder Grinding
Equipment: WFJ
Combine fine grinding and particle classification in a pulverizing system. The WFJ arrangement is reviewed against material brittleness, required fineness and the product collection duty. For fine powder processing, specify the fine pulverizer using representative powder grinding trials. Review particle size reduction and air classification together to define the required fineness, product recovery and acceptable temperature rise.
Product Overview
Combine fine grinding and particle classification in a pulverizing system. The WFJ arrangement is reviewed against material brittleness, required fineness and the product collection duty.
Working Principle
High-speed grinding reduces the feed in the pulverizing chamber. A classifier separates the finer fraction while returning oversize material for further size reduction, and the accepted powder passes to the collection system.
Key Features
- Grinding and classification work as connected operations.
- Oversize particles return for additional size reduction.
- Air handling and product collection form part of the system review.
Suitable Materials
- Dry, sufficiently brittle feeds that are suitable for fine grinding and classification.
- Assess the actual material properties, moisture or solvent content, temperature limits and required finished-product condition before selecting the machine.
Applications
Consider production of fine powder from compatible dry feeds. Validate the requested fineness and output together, as feed properties and classifier settings affect the finished particle distribution.

Confirm the selected configuration and material duty before ordering. Final dimensions, options and supply scope are recorded in the approved technical documents.
Selection and Configuration
State feed size, hardness, moisture, required fineness and throughput. Review temperature sensitivity, collection method, dust behaviour, cleanability and any specified containment or protection requirements.
For pharmaceutical installations, specify product-contact materials, containment, cleaning procedures, controls and documentation requirements. These are project requirements to be agreed, rather than an automatic claim of certification.
