Aluminum Dross Cooling and Screening Drum

Overview

The screening-type cold ash drum is a cooling and screening device used in conjunction with rotary furnaces, primarily for processing hot aluminum dross. It utilizes a spray cooling method to rapidly reduce the temperature of aluminum dross from over 700°C to below 50°C, effectively preventing combustion and oxidation. As a critical component in the recycling process of aluminum dross, this equipment plays a significant role in improving aluminum recovery rates. The screening-type cold ash drum consists of components such as water tanks, cooling drums, ball mill drums, screening drums, and control systems. It is available in three series based on drum diameter: 1200-type, 1600-type, and 1900-type. Each series offers five additional specifications based on length: 8 meters, 11 meters, 13 meters, 15 meters, and 17 meters.

Overseas Project Support

For export projects, Lanyu can configure the aluminum dross cooling and screening drum around local fuel or power conditions, plant layout, automation level, operator workflow and environmental requirements. The drum is usually specified together with a rotary furnace or dross handling line, so cooling capacity and screening targets should be confirmed early.
