Project Overview

A specialty mineral processing enterprise in Guizhou established a calcium oxide powder production line. The project required efficient handling of strongly alkaline, easily adhering calcium oxide. After comprehensive evaluation, the CRRM2150 Raymond Mill from Cronus Machinery was selected. This production line operates stably with high energy efficiency. The calcium oxide powder fineness is frequency-conversion adjustable between 200~325 mesh, and the output is flexibly controllable within the range of 15~20 t/h.

Project Details

Calcium Oxide Raw Material → Raw Material Silo → Belt Feeder → Raymond Mill

Calcium oxide material stored in the raw material silo is fed into the CRRM2150 Raymond Mill via the belt feeder for grinding. Considering the brittle texture, strong alkalinity, and easy adhesion characteristics of calcium oxide, the mill's core grinding components (grinding rollers/rings) are made of high manganese steel and other wear-resistant materials, with corrosion-resistant coatings applied to the inner walls. This effectively resists corrosion and wear, extending equipment life and ensuring the purity of the calcium oxide powder. The calcium oxide powder fineness can be flexibly adjusted between 200~325 mesh by changing the speed of the classifier impeller.

Cyclone Collector → Pulse Bag Filter → Screw Conveyor → Bucket Elevator → Finished Product Silo → Automatic Packing Machine

A two-stage collection system is employed. Parallel dual cyclone collectors serve as the primary stage, with efficiency improved by 10%~15% compared to a single cyclone, recovering most of the calcium oxide fine powder. The pulse bag filter serves as the secondary collection and final environmental protection device. It uses membrane-coated, waterproof, and oil-proof filter bags to prevent adhesion, ensuring exhaust emission concentration<30mg>

Project Advantages

Corrosion & Wear Resistance: The CRRM2150 Raymond Mill addresses the strong corrosion and abrasion characteristics of calcium oxide. Its core grinding components are made of special wear-resistant materials like high manganese steel, with corrosion-resistant coatings on the inner walls, solving a key industry challenge.

Precise Control: By frequency-conversion adjustment of the classifier speed, 200~325 mesh calcium oxide powder can be produced precisely and flexibly.

Clean Production: The entire process, from the raw material silo (anti-caking design) and enclosed conveying to the finished product silo (silo-top dust collector), adopts a negative-pressure enclosed design, completely preventing dust leakage and maintaining a clean production environment.
