Crushing Method on Manganese Slag

Manganese slag or silicon manganese slag is the residue of silicon manganese alloy smelting, There are dry residue and wet residue, in which manganese alloys exist. Recycling manganese alloy brings considerable economic benefits. The manganese slag must be crushed first, making the manganese alloy and slag monomer dissociated, and then using gravity separation to recycle silico-manganese alloys, however do you know the crushing method on manganese slag?
    
Manganese slag crushing is an important step for different manganese slag ally recycling. It should choose different ways and crushing equipment for mangnese slag crushing.
    
Wet mangnese slag has small particle size, foamy shape, it only need further crushing and Impact Crusher is an ideal crushing plant. For dry manganese slag, the multi-stage crusher will be helpful due to big particle size and great hardness, usually need two or three stage breaking to achieve the desired particle size. Generally speaking, the manganese slag crushing adopts two jaw crushing for coarse crushing or tertiary crushing(Efficient Impact Crusher or rod mill according to the actual situation). Impact Crusher crushing for dry slag also can get good effect, but it needs high cost, big equipment wear and tear, service time of wearing parts period is too short, so many customers are reluctant to adopt this crushing method, and they are more inclined to use rod mill crushing equipment. Altough rod mill needs large upfront investment, but the crushing cost is lower, efficient and low loss, is an ideal crushing equipment, which is commonly applied to smelting slag crushing.

Therefore the crushing method for dry manganese slag shall be two jaw crushing and rod mill crushing. And for wet manganese slag, the impact crusher for fine crushing.
