Coal gangue sintered brick preparation process capable of reducing lime burst and scumming harm
The invention belongs to the technical field of brick making, and particularly relates to a coal gangue sintered brick preparation process capable of reducing lime burst and scumming harm, which comprises the following steps: S01, sorting and removing: screening coal gangue and removing large limestone blocks, crushing the coal gangue and sorting out visible limestone, and then screening again; s02, fineness is controlled, wherein the particle size of discharged materials obtained after the coal gangue is subjected to primary coarse crushing, primary fine crushing and secondary fine crushing is smaller than 2 mm, and water is added for sufficient stirring after secondary fine crushing; s03, green brick forming: conveying the raw materials to secondary stirring, adding water to stir, conveying the raw materials to a brick machine to make bricks, extruding green strips by the brick machine, cutting the green strips into green strips with a certain length by using a strip cutting machine, and cutting the green strips into green bricks by using the green brick cutting machine; s04, reinforced roasting: roasting the coal gangue formed green bricks; s05, spraying water for digestion: spraying water on the formed coal gangue bricks; and S06, finished product acceptance: after the temperature of the brick is reduced to 45-55 DEG C, the brick is signed and inspected on site by quality inspection personnel. By means of the process, the harm of lime burst and scumming of the brick body can be reduced, and the quality of the finished brick is high.
本发明属于制砖技术领域，具体涉及一种可降低石灰爆裂和泛霜危害的煤矸石烧结砖制备工艺，包括以下步骤：S01拣选剔除：对煤矸石进行筛选并剔除大块石灰石，将煤矸石破碎并拣出能看见的石灰石后，再筛选一遍；S02控制细度：煤矸石经一次粗破、一次细碎、二次细碎后的出料粒径小于2mm，二次细碎后加水充分搅拌；S03砖坯成型：将原料再送至二次搅拌，加水搅拌后送到砖机制砖，砖机挤出坯条后，用切条机切成一定长度的坯条，再用切坯机把坯条切成砖坯；S04加强焙烧：对煤矸石成型砖坯进行焙烧；S05淋水消解：对成型的煤矸石砖进行淋水；S06成品验收：砖温降至45～55℃后，由质检人员现场签验。通过本工艺可降低砖体“石灰爆裂”和“泛霜”危害，成砖质量高。
