CR20 Intensive Mixers for Covering Flux (CO‑NELE)

2026.9.8  |  CO-NELE
The CR20 granulators are inclined batch‑type intensive mixers, developed for metallurgical covering flux, casting powder and ladle covering agent. It is suitable for powder, fine powder and systems with a small amount of liquid binder. It integrates mixing, dispersion and mild granulation, solving common pain points including large specific‑gravity difference among covering‑flux components, poor dispersion uniformity and material caking.

> Typical working conditions for covering flux: multi‑component powders (graphite, lime, fluorite, bauxite, etc.) with large density differences and addition of small amounts of water / binder. High dispersion performance, no agglomeration and stable batch‑to‑batch consistency are required to avoid metallurgical performance defects caused by local composition deviation.

Advantages for Covering‑Flux Granulator
1. High‑uniformity 3D turbulent mixing
Combination of inclined drum, high‑speed eccentric rotor and wall scrapers eliminates dead mixing zones. Light‑weight fractions such as graphite are prevented from floating and segregating. Formula uniformity of covering flux can be achieved within short mixing time to avoid metallurgical performance risks from uneven local composition.
2. Hydraulic central discharge with extremely low residue
Bottom‑mounted hydraulic discharge for fast material discharging. Wall and bottom scrapers clean the drum interior. Minimal powder residue reduces cross‑contamination during grade switching, ideal for producing multiple types of covering‑flux formulas alternately.
3. Custom wear‑resistant configuration for abrasive powders
Wear‑resistant liners and mixing blades are available for material‑contact parts to resist abrasion from covering‑flux powders. Optimized sealing structure suppresses fine‑powder dust leakage.
4. Flexible process expandability
Optional accessories: automatic liquid spraying system for quantitative binder/water injection, enclosed dust removal, jacket temperature control. Dispersion and mild granulation can be completed in one mixing cycle for granular covering‑flux output. Rotor and drum speeds are frequency‑conversion adjustable to match different covering‑flux processes.
5. Ready for automated production‑line integration
Compatible with feeding systems, batching silos and weighing units to realize full‑process automatic production of covering flux. Short batch cycle time suits medium‑to‑large‑capacity metallurgical auxiliary material plants.
Production Process for Mixed Granulation Using Covering Flux
Weighed batching & feeding → dry‑material pre‑mixing → liquid binder spraying → intensive mixing, dispersion & mild granulation → hydraulic central discharging → downstream conveying and screening.
