What Is An Aluminum Dross Press System And How Does It Work?

The efficiency and quality of aluminum dross recovery and treatment using aluminum dross press system is still very high, which can be processed quickly, avoid long-term contact with air oxidation, and the loss is too large, and can also optimize the factory environment to ensure its safety, especially high efficiency, and minimize operating costs.

In the process of aluminum smelting, some dross floating on the surface will be produced after oxidation reaction, but a certain amount of aluminum can be extracted and recovered. Aluminum, aluminum alloy, and recycled aluminum smelting process, will produce a large number of dross, generally 0.5%-10% of aluminum production, aluminum content in the dross is usually 30%-70%, and recycled aluminum dross aluminum content can be as high as 50%-80%.

Usually, the dross is mainly composed of the metal aluminum, alumina and different pollutants such as magnesium, iron, etc., but the proportion of each component varies according to the process of production and the specific conditions of the raw material. Aluminum is an important part of the waste dross, can be effectively recycled, but will be corroded by different components, so it needs to be treated quickly. Alumina is the most abundant part of the dross and reacts with oxygen in the air to form alumina, as well as other impurities. Therefore, some co-solvents can be properly used to optimize the melting process, thereby reducing the contact between aluminum dross and air, and effectively treating and recycling the dross.

Dross press can squeeze out the aluminum in the high-temperature aluminum dross by applying pressure, and at the same time, the dross is compacted, flame retardant, and cooling to prevent burning damage, and avoid the oxidation burning damage of aluminum in the aluminum dross, and also improve the working environment and conditions to ensure the safety factor of the operator. The aluminum dross processed by the dross pressing machine is massive, which is not independently completed by the traditional aluminum dross processing equipment, so the investment in the processing of aluminum dross is a good choice and program, which can maximize the value of resources and protect the environment.

Aluminum dross press system uses mechanical pressure extrusion to reduce aluminum dross and thus recover aluminum with higher purity. The following are important parts of a dross press system:

◇ Feed container and transports to get dross lumps

◇ Processor or smasher to lessen dross to more modest uniform sizes

◇ Warming heater to preheat dross (for cold dross)

◇ Pressure driven squeezing chamber and slam to pack dross at 100-150 psi

◇ Expelled aluminum assortment box

◇ Cake breaker and remixing arms

◇ Cake release framework

◆ The hydraulic system of dross press is to provide pressure and concentrate the recovered aluminum. The components of the hydraulic system are pumps, valves, cylinders, hoses, which work together and provide power to dross press.

◆ The blade is a part that helps remove impurities from the outer layer of liquid aluminum. The sharp edges scrape away the dross and drain it into sorting containers.

◆ Cooling framework is to control the temperature of the dross press to prevent overheating, this frame usually includes a water-cooled or air-cooled radiator, a fan and an indoor regulator to maintain the ideal operating temperature.

◆ The control panel is the control and adjustment of the system, which integrates a series of controls such as pressure and temperature checks, crisis stop buttons and other safety highlights.

◆ The extrusion chamber is used for dross management and extrusion of aluminum dross using an indenter, The pressed cakes go through additional processing to recover any remaining aluminum, while the product that was extruded flows into collection troughs.

The forklift truck transports the dross basin filled with hot aluminum dross to the dross box of the dross press machine. The dross press adopts the program setting to carry out automatic multistage pressing on it. At the same time, the cooling system of the pressure head is started to forcibly cool the aluminum dross, accelerate the solidification speed of aluminum liquid of the aluminum dross, and prevent the aluminum dross from continuing to oxidize in the air. The time and process of pressing are set according to the actual situation, usually set at about 20-40 minutes, and the system will automatically remind you after completion. After pressing the aluminum dross, part of the aluminum liquid in the aluminum dross is squeezed and stored in the collection tank below the dross basin, and the other part of the aluminum dross and aluminum are squeezed and cooled into the dross cake, and then enter the rotary furnace or similar equipment for secondary recovery.

In conclusion, using some equipment such as aluminum dross press system, not only can more aluminum be recovered, but also the quality is higher, and the operating costs are also saved.
