不是，煤矸石烧结砖是以煤矸石为结合剂的烧结砖工艺所生产的建筑材料。煤矸石烧结砖，从耐压、抗折、耐酸以及耐碱性能都高于粘土砖；从建筑用砖的成本方面来看，砌墙及粉刷前不用浇水，可节省用水费及人工费，同时，由于硬度高，产品在运输中的损耗比粘土砖低。
No, coal gangue fired brick is a building material produced by the technology of fired brick with coal gangue as binder. Coal gangue sintered brick has higher compressive, flexural, acid and alkali resistance than clay brick; from the aspect of cost of building bricks, it can save water and labor costs without watering before wall building and painting. At the same time, due to its high hardness, the loss of products in transportation is lower than clay brick.
煤矸石烧结砖是将煤矸石装入料斗经皮带机送至原料加工厂房，经锤式粉碎机粉碎、滚筒筛或振动筛筛选加工成合格物料，经过陈化的物料用皮带机送入二级搅拌及真空制砖机，然后用液压自动码坯机将砖坯码到窑车上送入烘干洞，将烘干的砖坯用摆渡车送到隧道窑口后顶入窑内烧结而成。
Coal gangue sintered brick is loaded into hopper percutaneous belt conveyor and sent to raw material processing plant. It is crushed by hammer mill, screened by drum screen or vibration screen and processed into qualified materials. Aged materials are fed into secondary mixer and vacuum brick making machine by belt conveyor, and then the brick is coded into kiln car by hydraulic automatic billet conveyor and dried. Dry cave, the dried bricks are sent to the tunnel kiln by ferry and sintered into the kiln.
