Double-Compartment Diaphragm

Product Overview

The TONGZHENG double-compartment diaphragm is a grinding mill internal partition designed to improve material classification and grinding efficiency. Its optimized two-compartment design promotes controlled material flow and appropriate particle residence time between grinding compartments, while optimized openings and internal configuration facilitate smooth airflow and material discharge, reducing material accumulation and ventilation resistance. Robust, reinforced construction provides good resistance to impact, abrasion and continuous mechanical loads, ensuring stable operation and convenient maintenance with reduced downtime.

Technical Specifications

What Is a Double-Compartment Diaphragm?

A double-compartment diaphragm is an internal partition installed inside a ball mill or similar grinding mill, dividing the mill shell into two grinding compartments. Material passes through the diaphragm from the first compartment to the second for further grinding to the required fineness, while the openings and internal structure regulate material flow, particle residence time and ventilation. Double-compartment diaphragms are widely used in cement, mineral powder and other dry grinding applications to improve classification, grinding efficiency and product fineness consistency.

Applications

• Cement grinding mills

• Raw meal and mineral powder grinding systems

• Other dry grinding processes requiring compartmentalized grinding

• Mill renovation and spare part replacement
