免烧砖是以各种类型粘土为主要原料,加入少量胶结材料经计量配料、搅拌、成型、自然或蒸气、蒸压养护而成的。按材料组合可分六种类型:粘土+水泥;粘土+石灰;粘土+水泥+石灰;粘土+工业废渣+水泥;粘土+工业废渣+水泥+石灰;粘土+砂+高钙粉煤灰。免烧砖是一种新型墙体材料,可用劣质粘土、砂土、贝岩、高岭石土、某些尾矿等原料进行生产,有利于保护耕地节约能源。但是,免烧砖技术在国内处于开发初期,生产成本较高,必须有计划、有组织地进行。生产设备 1.采土多用推土机、挖土机,也可用人工开采。 2.破碎。土多采用LP—40型笼式破碎机,该机在
The unburned bricks are made of various types of clay as the main raw material, and are made by adding a small amount of cementitious materials through metering, stirring, forming, natural or steam, and autoclave curing. According to the material combination, it can be divided into six types: clay + cement, clay + lime, clay + cement + lime, clay + industrial waste residue + cement, clay + industrial waste residue + cement + lime, clay + sand + high calcium fly ash. The unburned brick is a new type of wall material that can be used for the production of inferior clay, sand, shell rock, kaolinite soil, certain tailings and other raw materials, which is conducive to the protection of cultivated land and energy conservation. However, the unburned brick technology is in the initial stage of development in China and the production cost is high. It must be planned and organized. Production equipment 1. Earthmoving bulldozers and excavators can also be used for artificial mining. 2. Broken. Tudor uses the LP-40 type cage crusher.
