The invention belongs to the technical field of material preparation, and discloses a method for preparing a dust-falling and dust-absorbing material from non-metallic minerals and
cement plant production raw materials. The method comprises the following steps: calcining limestone blocks to obtain quick
lime; cooling quick
lime at the
room temperature,
drying, crushing quick
lime to obtain calciumcarbonate
powder;
drying nonmetallic minerals,
grinding nonmetallic minerals to obtain nonmetallic mineral
powder; mixing
calcium carbonate powder and non-metallic mineral powder, stirring, carryingout ball milling to obtain nano powder; adding a dust collection material, adding water, mixing, pouring the mixture into a mold,
drying; and drying in the air to obtain the hollow dust-
settling and dust-absorbing material. The raw materials are convenient to obtain, the cost is low, the material preparation cost can be effectively reduced, the dust-
settling and dust-absorbing material can be recycled after dust adsorption, and resources are effectively saved. By adding the dust collection material, the adsorption force can be enhanced, higher adsorption capacity is generated for
dust particles, and the dust collection effect is better.
