Description
Technical field
The invention belongs to the artificial lightweight aggregate processing technique field, be specifically related to a kind of light hollow haydite and preparation method thereof.
Background technology
Now widely used artificial lightweight aggregate mainly is sintering-expanded haydite, it is to utilize clay, shale or flyash etc. can burn swollen raw material to add water stirring, balling-up that tradition is made sintering-expanded haydite, utilization can be burnt the characteristic that swollen raw material at high temperature expands, in high temperature rotary kiln through expanded and form spheroid or the ball column of porous, be exactly sintering-expanded haydite after the cooling, they are the shapes such as irregular inferior circle shape, inferior water caltrop shape more.The raw material of producing sintering-expanded haydite must be to burn swollen raw material, and this raw material is few at nature, therefore generally need to improve its expansion characteristics with additive, because the material performance difference such as clay, shale are larger, even same batch of material performance also there are differences, and the use of additive had both increased the swollen effect of burning after the production cost of sintering-expanded haydite is difficult to stable the adding, quality product is made a big impact, and this method had also greatly been wasted land resources.The swollen performance of basic not burning also can't expand to make the lightweight sintering-expanded haydite even add additive after the batching such as some regional clay, shale, and this is so that there is the limitation on the raw material in the manufacturing of sintering-expanded haydite.Moreover the production process of sintering-expanded haydite is at high temperature expanded and form the spheroid of porous, and energy consumption is high, cost is large, and it is low to obtain the intensity of sintering-expanded haydite; In addition, guarantee product performance and product size by material performance, be difficult to control on the technique, only have to burn and sieve to control product size after swollen, what general particle diameter was large is haydite, and what particle diameter was little is pottery sand.In order to address this problem, development hollow haydite is imperative, Chinese patent CN 200510041886.5 provides a kind of preparation method of hollow haydite, by extruding first the hollow circular tube base substrate with extrusion method, and then cut into segment, and in pan-pelletizer, be molded into irregular hollow haydite base substrate, in high-temperature calcination equipment, burn out again at last the hollow haydite.Propose similar method among the Chinese patent CN 91110948.X " shaft kiln cement raw material hollow forming equipment and technique " and also can prepare the irregular hollow haydite of profile, when these haydites prepare light concrete as light-weight aggregate, at first be shaped as irregular, easily produce stress concentration when forming concrete structure, secondly, irregular haydite generation space resistance is larger during stirring, haydite is easily destroyed, concrete easily stirs inhomogeneous, moreover, the aforesaid method moulding is not easy to form the hollow haydite of cavity sealing, and the water ash mass ratio when causing preparing light aggregate concrete is not easy control.In view of above situation the present invention proposes a kind of hollow haydite and preparation method thereof, prepared hollow haydite is that sphere or the class of internal cavities sealing is spherical, and can carry out on a large scale, at low cost the production of hollow ceramic product.
