A Method of Preparing Calcium-Magnesium Inorganic Fertilizer Made From Dolomite Waste Firebrick Of Steel Making

摘要

calcium with lung dolomite refractory bricks for steel making - as on the magnesium dolomite refractory lung mineral fertilizer production process calcium by bricks and dolomite refractory pulmonary hydration of water per brick 370~400kg 1000kg - magnesium mineral fertilizer is produced. ; After using the equipment for the steel mill without the burden of manufactured fertilizers with dolomite refractory bricks lungs raw material that is discarded as a raw material . First , Second and effective for the prevention of soil acidification , and the third to the recycling of waste resource conservation , and contribute to landfill life and environmental protection due to reduced landfill waste , except for the power source of the fourth production process of the unit does not require a separate heat source or energy . Thus, low-cost high-quality calcium - magnesium mineral fertilizer is provided.
