Because the density of the aluminum material is only slightly higher than that of the nonmetallic slag sand material, the aluminum material is difficult to separate from the sand material by using the buoyancy selection process, and if the aluminum material is not treated by the aluminum separation system process, the purified sand material cracks the brick body due to the oxidation reaction of the aluminum material during brick making. Therefore, sand materials with granularity of 32-75 mu m, 75-3 mu m and 3-40 mm and slag heads (orthopaedics materials) with granularity of >40mm in the working procedures of the sand material granularity grading and dewatering system are respectively recycled through the eddy current separator of the aluminum separation equipment.
When the aluminum material passes through the nonferrous metal eddy current separator, eddy current is generated to generate reverse magnetic field force which is repelled with the self magnetic field of the eddy current separator, so that the aluminum material flies out of slag.
