MillNest Air Classifying Mill (MACM)

Precision Size Reduction with Integrated Classification

Overview

The MillNest Air Classifying Mill (MACM) is a pulverizer with an integrated classifier that utilizes a unique system of internal circulation to achieve precise size reduction. By combining impact milling with air classification, the MACM produces fine powders more efficiently while maintaining a critical particle size distribution, ensuring superior product quality.

Customizable to handle specific requirements such as grinding to >250 microns, the MACM minimizes temperature rise during the pulverizing process to suit the solids being ground. Engineered for precision and consistency, it is the ideal solution for industries like food, pharmaceuticals, chemicals, and minerals, where uniformity and control are critical.

Working Principle

The MillNest MACM operates by combining impact grinding and air classification in the following steps:

01
Material Infeed

Raw material is introduced into the grinding chamber through a top-mounted feed inlet. Materials can include powders, granules, or other dry solids requiring size reduction.

02
Impact Milling

High-speed rotating hammers or blades strike the material, breaking it into smaller particles through impact and shearing forces.

03
Air Classification

A controlled air stream carries the finer particles into a classifier zone, where centrifugal force separates them from coarser particles.

04
Discharge

Fine particles exit through a cyclone separator or filter bag, while oversized particles are recirculated to the grinding chamber for further reduction.

05
Output

This integrated approach delivers precise, repeatable results, enabling tight control over particle size distribution.
