Dross cooling barrel is a specialised piece of equipment used in the aluminium processing and recycling industry to rapidly cool hot aluminium dross (slag) skimmed from melting furnaces.
Product Introduction
- The main function is the rotary furnace(rubbing machine)extraction of aluminum and water after the heat aluminum dross by water spray heat exchange cooling and screening,the 700-900°C high temperature aluminum dross in a short period of time is reduced to below 50°C,avoid high temperature combustion and oxidation of aluminum dross,so as to improve the recovery of aluminum dross the rate of production,the economic benefit is obvious.
- The straight type guide strip,roller+ball type pressure dross,cooling time is short,strong processing ability,waste aluminum dross coarse and fine classification,has low investment cost,low operation cost,low maintenance cost,aluminum dross in aluminum content is small,high work efficiency,good economic benefit,less environment influence advantages.
Why is rapid cooling of aluminium dross necessary?
Aluminium dross is a by-product that floats on the surface of molten aluminium during melting.It contains between 10% and 90% of metallic aluminium, making it a valuable recyclable resource.
Prevents oxidation and burning of aluminium:
– Freshly skimmed dross has a temperature as high as 700–900 °C. If left to cool naturally, the hot dross will continuously react with oxygen in the air, causing the metallic aluminium to burn and oxidise, resulting in a 5–10% aluminium loss.Rapid cooling effectively stops this process and significantly improves aluminium recovery.
Reduces harmful fumes:
– Natural cooling releases large amounts of harmful dust and gases.The cooling barrel, being a relatively sealed system, effectively suppresses dust emissions and improves the plant environment.
How does it work
The term “Dross Cooling Barrel” most commonly refers to the rotary cooling barrel, which operates as follows:
Loading:
– Hot aluminium dross is fed into an unlined steel drum through the inlet.
Rotation and cooling:
– The drum rotates slowly around its horizontal axis, continuously tumbling the dross inside. Simultaneously, cooling water is sprayed onto the outside of the drum. Heat is transferred through the drum wall to the water,achieving indirect water cooling – this avoids direct contact between water and the hot dross, which could be dangerous.
Discharge:
– The residence time inside the barrel is typically 10 to 20 minutes.After cooling,the dross is discharged through the outlet.
Our company product also can install the CMS system on different devices.The CMS is an industrial interconnection PaaS platform that provides customers with overall olutions for intelligent equipment systems and assists in the digital transformation and upgrading of users in the non-ferrous metal industry.It is very convenient to use.The CMS system can provide web publishing and mobile apps that can be accessed anytime and anywhere through computers,tablets,and mobile phones.And it can integrate custom multilingual tools,allowing for the free addition of new languages,making it easy to switch between multiple languages.
The dross cooling barrel addresses two major pain points associated with natural cooling of hot aluminium dross: severe metal burn-off and high environmental pollution, by applying forced rapid cooling. It is a key piece of equipment in the modern aluminium processing industry for achieving efficient resource recovery and cleaner production.
