Steel slag, lithium slag, furnace slag and stone powder mixed grinding production process
The invention relates to a steel slag, lithium slag, furnace slag and stone powder drying and grinding production process. The steel slag, lithium slag, furnace slag and stone powder drying and grinding production process is characterized in that lithium slag, furnace slag, stone powder and steel slag are used as raw materials for mixed grinding, and the drying and grinding production process mainly comprises a raw material drying process, a batching process and a mixed grinding process in sequence; in the raw material drying process, the lithium slag and the furnace slag are controlled to bedried until moisture content of the furnace slag is less than 0.7%, the stone powder is controlled to be dried until moisture content of the stone powder is less than 0.5%, the steel slag is controlled to be dried until moisture content of the steel slag is less than 1.0%, and the dry lithium slag, the dry furnace slag, the dry stone powder and the dry steel slag are obtained respectively; and inthe batching process, a mixed grinding raw material is obtained by weighing and proportioning according to the proportion: the dry lithium slag : the dry furnace slag: the dry stone powder : the dry steel slag is 2.2-3.2:1:0.7:2. The steel slag, lithium slag, furnace slag and stone powder drying and grinding production process has the advantages that the mixed powder produced by direct grinding isused as a concrete admixture, a traditional mixed production process is simplified, the product quality uniformity is improved, and the production energy consumption and the cost are reduced; and theaverage energy consumption is 17.6 KWh/t when the powder fineness is 400 m<2>/Kg or above.
本发明涉及一种钢渣、锂渣、炉渣、石粉烘干及粉磨生产工艺,其特征在于:所述工艺以锂渣、炉渣、石粉、钢渣为原料进行混合粉磨,其依次主要包括原料烘干工序、配料工序、混合粉磨工序,所述原料烘干工序中,控制锂渣、炉渣烘干至水分<0.7%,控制石粉烘干至水分<0.5%,控制钢渣烘干至水分<1.0%,分别得到干锂渣、干炉渣、干石粉和干钢渣;所述配料工序中,按干锂渣:干炉渣:干石粉:干钢渣=2.2~3.2:1:0.7:2的比例进行称量配比得到混合粉磨原料。本发明优点是直接粉磨生产混合粉作为混凝土掺杂料,简化了传统混合的生产工艺,提高了产品品质均匀度,降低生产能耗和成本。在粉磨细度达400m/Kg以上的混合粉时,平均能耗为17.6KWh/t。
