早在八十年代末、九十年代初,随国内高层、超高层建筑、高标准住宅、厂房以及高级公路、立交桥、混凝土预制构件、砌块机械化生产等飞速发展,对混凝土生产的速度、质量要求越来越高,而影响其生产效率及质量的关键就是原料的连续自动精确配比。国内机械秤、电子秤自动配料机应运而生,宇锋公司成为全国最早、销量最大的混凝土配料机 As early as in the late 1980s and early 1990s, with the rapid development of domestic high-rise buildings, high-rise buildings, high-standard residential buildings, factory buildings, and advanced highways, overpasses, prefabricated concrete components, and block mechanical production, the speed and quality of concrete production The demand is getting higher and higher, and the key to affecting its production efficiency and quality is the continuous automatic precise ratio of raw materials. Domestic mechanical scales and electronic scales automatic batching machines came into being. Yufeng became the country’s first and largest-selling concrete batching machine.
