1) for bulk material in front of lime and sand mix the ingredients must be crushing, grinding fineness of the production process to achieve the required general chunk of lime used jaw crusher for crushing. Needs to be crushed lime powder Grinding General grinding ball mill for lime (2) mix design mix sand-lime brick ① Mix ratio shall meet the following requirements a. physical and mechanical properties, especially compressive strength requirements. General compressive strength 10Mpa above requirements, and also to meet the frost, carbonation, acid, fire resistance, shrinkage and other performance requirements. b. to meet the brick molding of the plastic mix requirements. c. Mix to try to reduce the cost of sand-lime brick Huangpi Which is good, increase economic efficiency. Our research and development since 1958 autoclaved lime sand brick, 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 rotary PRESS Huangpi gray sand brick factory, which greatly promoted the development of autoclaved lime sand brick, make it have sand, lime and clay resources in the region and lack of resources of the main wall material.
