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。
Coal gangue sintered brick is a kind of building material produced by the technology of sintering brick with coal gangue as binder.
生产工艺的主要环节有：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，然后送入一级搅拌加水后送入陈化仓进行陈化。把经过陈化的物料用皮带机送入二级搅拌及真空制砖机制成砖坯，然后用液压自动码坯机将砖坯码到窑车上送入烘干洞进行烘干，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为成品砖。
The main links of the production process are: the gangue is loaded into the hopper, sent to the raw material processing plant by the belt conveyor, crushed by the hammer crusher, screened by the roller screen or the vibrating screen and processed into qualified materials, and then sent to the first level mixing and adding water, and then sent to the aging warehouse for aging. The aged materials are sent to the secondary mixing and vacuum brick making mechanism by belt conveyor to make bricks, and then the bricks are sent to the kiln car by the hydraulic automatic brick coding machine to the drying hole for drying, and the dried bricks are sent to the tunnel kiln mouth by the ferry car and then put into the kiln for sintering to become finished bricks.
煤矸石制砖，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。
Coal gangue brick is superior to clay brick in terms of pressure resistance, folding resistance, acid resistance and alkali resistance; in terms of the cost of building bricks, no water is needed before building and painting, which can save water and labor costs. At the same time, due to high hardness, the loss of products in transportation is lower than clay brick.
