Autoclaved sand-lime brick production process, including raw material preparation, several major mixture preparation, brick molding, autoclave curing and finished on the village. 1. sand and lime are the main raw materials to produce sand-lime brick, sand available river sand, sea sand sand-lime brick size, aeolian sand, depositing sand and concentrator tailings, etc., depending on the type of sand of different characteristics and mines, respectively take a different approach to mine. Lime production is mainly taken by calcining. 2. Preparation of the mixture before, must be compared with the design. Mix design actually find technically and economically optimized critical point. Mix primitive conditions during the design, to be considered are: material properties (mineral sand and sand-lime brick particles size, chemical composition of lime, lime the calcium oxide content, hydration rate and temperature, etc.), product quality requirements and pressing, curing conditions. Prepared mixture containing lime digestion, measurement mixture with stirring, the mixture of digestion, digestion mixture treatment processes. 3. Forming sand-lime brick production process is the most important aspect, including four production steps of: feeding, pressing a blank, blank code blank taken. The second stage, heating stage boost. It mainly refers to the kettle through steam, steam and product reaches a predetermined pressure, the process temperature. At this stage, in order to avoid steam kettle, adobe brick surface inside the three large temperature difference caused by the temperature difference due to the brick surface and internal inconsistencies and cracks, must control the heating rate (which is related to the initial structural strength of the brick), so heating rate is not too fast, the general control 1.5 ~ 2h appropriate.
