Automatic Aluminum Ash Treatment Equipment

INTRODUCTION

The automatic aluminum ash treatment equipment is suitable for all aluminum processing enterprises that use metal aluminum as raw material and melt metal aluminum as the production process, such as electrolytic aluminum factories, aluminum parts factories, and aluminum alloy factories. Used in conjunction with the aluminum melting furnace, it can also be used in the treatment process of aluminum ash and aluminum slag, or the smelting operation of recycled aluminum that does not contain iron, copper, stainless steel and other metals. The purpose of using this automatic aluminum ash treatment equipment is to separate and recycle the metallic aluminum contained in the aluminum ash produced during the smelting process, increase the utilization rate of metallic aluminum, reduce losses, and reduce costs.

PRODUCTION PROCESS

Pull out the hot aluminum ash and aluminum slag from the smelting furnace into the hot slag pot. Then use a forklift to deliver the hot aluminum ash and aluminum slag to the ash frying machine, and start the equipment. Through stirring, separate metallic aluminum with different specific gravity from hot aluminum ash.

Before the stirring starts, the operator decides to stir directly or add heating agent according to the temperature state of the hot aluminum ash to keep the hot ash in a burning state for stirring. After the hot aluminum ash is removed from the smelting furnace, it is stored for a long time and the temperature of the aluminum ash drops below 700℃. It is necessary to add a heating agent for stirring and separation.

After the separation, the hot aluminum ash is automatically transferred and poured into the cooling cylinder for cooling through the transfer and turning device, and then passes through the ball mill system, where the temperature of the hot aluminum ash is cooled from about 700℃ to about 50℃, and then enters the  grading sieve device. It is divided into three products, one is particles below 0.5mm, one is medium particles between 0.5mm and 15mm, and one is lumps above 15mm. Objects below 0.5mm and lumps enter the ton bag, medium particles are automatically transferred to the cooling cylinder for recycling, and the excess portion is put into the ton bag. During the operation, ash frying, pouring and sieving will produce a large amount of flue gas dust. Each collection port passes the flue gas dust through cyclone filtration and then adds it to the filter cartridge for secondary filtration before being discharged into the atmosphere.
