Aluminium powder is the third most abundant material on the earth’s crust. This metal is a strong, non-toxic, nonmagnetic, and lightweight material. Bauxite is the ore that is used to manufacture aluminium. It consists of 40-60% aluminium oxide along with impurities like sand, iron, and other metals.
The aluminium is widely used from foils to aircraft parts and from cans to window frames. Every manufacturer desire to create a high-quality product to get the high price of it in the market. The quality of the product can be improved through purity in the product and removing unwanted impurities from it. Let us discuss how a perfect sieving solution can give you the top-notch quality product.
The aluminium powder is manufactured in various forms that can be flakes, granules, and powder. Aluminium ingots or pallets are brought to the factory and melted in the furnace at 720 to 760 C. Molten aluminium is then passed to spray atomization and different grades of aluminium powder are obtained.
Sieving is a very important step in aluminium powder processing. Aluminium powder is graded into different sized particles. Each particle has to be of equal size to get uniformity. The Uniformity of the particles brings high-quality application products.
Manufacturers are facing a lot many problems while sieving with a traditional Vibro separator or sieving machine. The common problem is the throughput capacity of the sifter. Many conventional sifters are made without considering the factors that are involved while sieving.
The physical factors are material properties like bulk density, humidity, temperature, viscosity, and many more. Based on that you decide what vibration, deck, material flow medium, and lead angle should be to get the desired throughput capacity or results.
Multideck Vibro Sifters from Dongzhen Machinery are used for grading aluminium powder from coarse to fine powder. Each graded material is accurate, uniform, and free from any foreign impurity introduced at the processing stages. These powders are then packed and sent to different manufacturers to build different aluminium products.
