Our research and development since 1958 autoclaved sand-lime brick, light brick building precise, in 1960 from the former East Germany to introduce sixteen hole rotary PRESS in Beijing built autoclaved sand-lime brick production line, and later developed eight-hole wheel type press, greatly promoted the development of autoclaved lime sand brick, making it have sand, lime and clay resources in the region and lack of resources of the main wall material. (1) Product Specifications GB GB11945-1999 the provisions of brick shape was rectangular hexahedral, precise light brick, brick nominal size length 240mm, width 115mm, height 53mm. Production Other sizes products, consultation is determined by the user and production. (2) the mechanical properties specified in the GB11945-1999 MU10, MU15, MU20, MU25 four intensity levels, precise light brick network, see Table 2-7 autoclaved sand-lime bricks and autoclaved fly ash brick is powder slag or ash or other ash sand as raw material, add lime, gypsum and aggregate, billet prepared by, pressing, efficient steam curing process made. Autoclaved brick equipment including: mixers, digestion machine, steam press, wheel mill, autoclave and other equipment to the main steam press equipment, and box-type feeder, screw conveyor, bucket climb, aggregate He said belt conveyor, maintenance car, ferry vehicles, and other auxiliary equipment.
