为保护耕地、治理环境污染、开发新型墙体材料,河南巩县孝南建材机械厂贯彻中央的“限制毁田烧砖、推动墙体材料改革”的通知,研制成功新型免烧压砖机。该厂通过对发电厂、化工厂、化肥厂、酒精厂、冶炼厂、碱厂等厂排放的废渣及矿山煤矸石的调查,经过两年的努力,终于与河南省建筑材料研究设计院共同研制开发成功一种以各类尾矿渣等为原料制砖的 MSZ60-8A 型免烧压砖机械成套设备,并已通过技术鉴定,批量投入生产。该压
In order to protect cultivated land, control environmental pollution, and develop new wall materials, Henan Gongxian Xiaonan Building Materials Machinery Factory implements the Central Circular on “Restricting the Destruction of Bricks and Burning Bricks and Promoting the Reform of Wall Materials” and has developed a new type of unburned brick press. After two years of efforts, the plant has finally completed a joint research with Henan Provincial Building Material Research and Design Institute through the investigation of waste residue and coal gangue discharged from power plants, chemical plants, chemical fertilizer plants, alcohol plants, smelters, and alkali plants. The company successfully developed a MSZ60-8A free-burning brick machinery complete set of equipment that uses various types of tailings slag as raw materials, and has passed technical appraisal and put it into production in batches. The pressure
