Description
Technical field
The utility model relates to a kind of chalk and prepares cement slurry system, particularly relate to a kind of in finely powdered and the higher chalk material of moisture to prepare the process system of raw material.
Background technology
Chalk, also known as carclazyte powder, is a kind of settling of fine calcium carbonate, is the mutation of calcite.The ball algae becoming the coccolith source of structure chalk is a kind of vegetal Flagellata, it has two isometric flagellums, body is spherical size is 3 ~ 35 microns, the lime mass shell small in a large number covered at its cell surface is exactly coccolith, be the oblate shape of 1 ~ 11 micron of size or flat ellipticity, the horn-like projection of tool sometimes.On seawater, many minimum animal and plants adrift, one is wherein had to be called the protistan in " polyembryony hole ", the shell of these biologies is made up of lime, after these organisms die, their extremely small bodies sink to seabed, and if things go on like this, bonding forms chalk or chalk soil gradually.Due to the various motions of earth surface, often make those original underwater soils become land, originally lifted at the chalk soil layer in seabed and moved.
The main component of chalk is calcium carbonate, and calcium oxide content, generally more than 50%, is the natural good raw material producing cement.Chalk is except being applied to Cement industry, and making chalk is its comparatively common application.Chalk is generally formed in ocean; particle own is very thin; dry that to break up rear median size also less than the raw meal powder of calcining cement clinker; substantially the levigate requirement that can meet cement slurry need not be continued; but often contain more impurity in chalk as soil, sand etc.; these particles are also relatively thick, need to select and in addition grinding, to meet the requirement adding nodules degree in man-hour.
Chalk is generally from mine working exploitation, and moisture content is comparatively large, generally 20 ~ 40%, and has certain viscosity.On Europe and other places, the main wet method that adopts ground to produce cement in the past, and along with the maturation gradually of novel dry production cement industry, its all technical is obviously better than wet process technique, and wet production cement industry is eliminated gradually.Water content is higher and the chalk that fineness is thinner, needs oven dry to make dry powder material, could should be used for preparing cement clinker on new dry cement technology.
For the material that moisture is higher, ball mill is difficult to meet the requirement of drying, and usually adopts Vertical Mill to dry powder-grinding process of holding concurrently; But for fine powder, the powder abrasive bed of Vertical Mill is difficult to steady running; The main effect of Vertical Mill is grinding, and lumpy material is ground to pulverulent material, and do not need the fine powder pulverized further for only breaing up, Vertical Mill is obviously improper, wastes grinding energy again.Raw material are made up of according to certain rate value and ratio calcareous raw material, siliceous raw material, aluminum raw material, ferriferous raw material etc., and be satisfactory powdery dry material by the raw material grinding after batching combination, cement clinker can be fired at follow-up new dry process for cement production.
When the calcareous raw material employing chalk of raw material, other several raw material is usually based on lumpy material, need these lumpy material grinding powdering materials through grinding device, if now take the Technology of traditional grinding of first preparing burden again, often need to select very large milling equipment, and the chalk accounting for about 80% of raw material composition does not need to pulverize, only need break up, dry, other takes separate grinding at the less lumpy material of raw material component accounting example, and then carry out being mixed into raw meal powder with the chalk powder of drying separately, greatly can reduce the specification of grinding device, can invest by less equipment construction, operation power consumption can be reduced again, the production costs such as equipment attrition.
