Jig recycling chrome iron slag process
Ferrochromium slag is a solid waste generated during smelting ferrochrome alloy, mostly dry residue, greater hardness, due to the limitation by the smelting process, the multi ferrochrome slag contains a certain amount of ferrochromium alloy particles, since the magnetic permeability than ferrochrome Low, it is difficult to obtain the ideal sorting effect by magnetic separation. Therefore, the chrome-iron alloy in the ferrochrome slag is recovered by the method of re-selecting the jig, and the ferrochrome jig is also appeared.
The chrome-iron alloy in the ferrochrome slag has uneven grain size, the largest can reach about 30mm, and the smallest is less than 1mm. In order to recover as much chrome-iron alloy as possible, it is often necessary to crush, grind and jirt the chrome-iron slag. When the process is recycled, the price of coarse-grained ferrochrome is higher, and the price of fine-grained ferrochrome is lower. Therefore, it is necessary to recover coarse-grained ferrochrome as early as possible to ensure maximum profit.
The hardness of ferrochrome slag is relatively large. Therefore, the crushing process is mostly crushed and finely crushed by a jaw crusher . After that, it is sieved by a vibrating sieve. The coarse grain enters the large particle jig sorting, and the fine grain is combined with the large particle jig. The tailings are mixed into the rod mill for grinding, and the grinding products enter the trapezoidal jig for secondary sorting, and finally the chrome-iron alloy particles of different size are obtained to obtain the maximum economic benefit.
After many practical results, the best method for ferrochrome recovery in ferrochrome slag is the jig re-election method. The recovery rate of the chromite alloy is higher than 90%, and the equipment investment is small, and the operating cost is low. Low, very suitable for small and medium sized ferrochrome treatment plants.
The chrome iron slag jig mainly refers to the large particle jig and the trapezoidal jig. The combination of the two types of jig equipment can complete the sorting and recovery of 0 to 30 mm granular ferrochrome slag, and the sorting effect is remarkable. It has been accepted by many customers.
