Aluminum slag recover machine combined with ball mill and hot aluminum dross cooling machine together to archive aluminum slag recover process.
The hot aluminum dross extracted from molten aluminum in an aluminum dross separator or rotary furnace can be cooled to room temperature within 10-15 minutes through water spray heat exchange, avoiding the burning, oxidation, and classification screening of high-temperature Aluminum dross. Mechanized operation can be basically achieved, the hot aluminum dross and fine ash (40-80 mesh) can be automatically separated and sent back to to melting furnace for re-melt process.
Aluminum dross ball mill is a specialized equipment used for processing Aluminum dross. Its working principle is based on mechanical grinding and separation technology, aiming to efficiently recover metal aluminum and aluminum oxide from Aluminum dross. The following is a detailed analysis of its working principle:
1. Basic structure and composition
The Aluminum dross ball mill is mainly composed of a feeding device, a cylinder, a discharge end, a transmission device (such as large and small gears), and a grinding medium (such as steel balls). The inner wall of the cylinder is usually lined with corrugated or stepped lining plates to enhance the grinding effect.
2. Grinding process
Feeding and distribution: Aluminum dross enters the interior of the cylinder uniformly through the feeding device and hollow shaft.
Rotation and centrifugal force: After starting, the transmission device drives the cylinder to rotate, and the steel ball and Aluminum dross are lifted to a certain height under the action of centrifugal force and fall down, causing impact and grinding on the Aluminum dross.
Grinding and Separation: The mutual stirring and crushing of steel balls and Aluminum dross gradually separates the aluminum from the ash. Metal aluminum and aluminum oxide are effectively screened during the grinding process due to differences in density and particle size.
3. Discharge and Recycling
Discharge method: The ground material is discharged through the discharge end, and some equipment uses a wind discharge system to separate and recover fine particle materials through a pipeline system.
Recycling efficiency: The Aluminum dross ball mill reduces aluminum wear and improves the recovery rate of metallic aluminum by optimizing the grinding medium and lining plate design.
4. Environmental protection and energy conservation
Aluminum dross ball mills pay attention to energy conservation and environmental protection in their design, such as using self coupling pressure reduction starting to reduce current, and reducing dust pollution through wind discharge.
5. Application scenarios
Aluminum dross ball mills are widely used in electrolytic aluminum plants, aluminum parts plants, alloy aluminum plants, etc., to process the Aluminum dross generated in the production process of electrolytic aluminum and achieve efficient recovery of metallic aluminum and aluminum oxide.
Summary: The Aluminum dross ball mill efficiently recovers metal aluminum and aluminum oxide from Aluminum dross through mechanical grinding and separation technology, while also considering energy conservation and environmental protection. It is an important equipment in the field of Aluminum dross treatment.
Cooling machine, also known as aluminum ash cooling machine or cold ash bucket
Its purpose is for rapid cooling and processing of hot aluminum slag in aluminum profile forming furnaces. This device is also known as a cooling machine, aluminum slag cooling machine, aluminum slag cooling machine, or hot aluminum ash cooling machine.
Structure and principle of aluminum ash Hot aluminum dross cooling machine
- Structure: The cooling machine consists of a cylinder, front roller ring, gear, stop roller, drag roller, small gear, discharge part, reducer, motor, cooling water, etc. In addition, technical cooling tanks or supporting elevators, conveyor belts, etc. can be installed according to customer needs.
- Working principle of the cooling machine: The material enters the cooling machine cylinder, and as the cylinder rotates, it moves forward and directly or indirectly receives heat from the heat carrier, cooling the hot material. It is then cooled by the water tank and output from the feeding end.
Advantages of Hot aluminum dross cooling machine
The Hot aluminum dross cooling machine can quickly cool high-temperature materials while recovering heat. Widely used for ash cooling and transportation in circulating fluidized bed boilers, bubbling bed boilers, and boiling boilers.
