Description
技术领域technical field
本发明涉及筛选机技术领域，尤其涉及一种用于生产水泥的废石粉筛选机。The invention relates to the technical field of screening machines, in particular to a waste rock powder screening machine for producing cement.
背景技术Background technique
石粉是石头的粉末的通称，石头的种类很多，根据矿物成分划分有很多品种，并不一定是碳酸钙。碳酸钙是石灰石，只是石粉中的一种，石粉中还有滑石粉，用于制作腻子。还有石英粉，用作制作玻璃。还有很多矿物成分的岩石，都可以磨成粉末，用作不同的工艺及用途，而水泥是一种粉状水硬性无机胶凝材料。加水搅拌后成浆体，能在空气中硬化或者在水中更好的硬化，并能把砂、石等材料牢固地胶结在一起，实际生产中，水泥可以稳定石粉的干缩，温缩，水泥和石粉混合后，其凝固后不仅硬度增强而且强度和密度都有所提升；在水泥和石粉混合之前，需要对石粉进行筛选，而现有的筛选设备效率较低，不利于批量生产。Stone powder is a general term for stone powder. There are many types of stone, and there are many varieties according to the mineral composition, not necessarily calcium carbonate. Calcium carbonate is limestone, which is just a kind of stone powder. There is also talcum powder in the stone powder, which is used to make putty. There is also quartz powder, which is used to make glass. There are also many rocks with mineral components, which can be ground into powder for different processes and purposes, and cement is a powdery hydraulic inorganic gelling material. Add water and stir to form a slurry, which can be hardened in air or better in water, and can firmly bond sand, stone and other materials together. In actual production, cement can stabilize the dry shrinkage and temperature shrinkage of stone powder. After mixing with stone powder, not only the hardness increases but also the strength and density are improved after solidification; before cement and stone powder are mixed, the stone powder needs to be screened, and the existing screening equipment is inefficient, which is not conducive to mass production.
