The rolling screening machine is suitable for the sorting of waste materials before entering the furnace in the aluminum and recycled aluminum industry. By configuring the size and air volume of different sieve holes, dust, mud, fibers, etc. can be removed, and the waste can be classified according to different sizes. Then, the iron in the waste can be removed by the end magnetic separator, making it easier to control the composition of the waste materials fed into the melting furnace with fewer impurities.
