The invention discloses a stone powder brick making process. The stone powder brick making process comprises the following steps: step 1, a slurry mixing procedure; step 2, a grading process: gradingthe stone powder slurry a obtained in the step 1; step 3, a concentration process: concentrating and dehydrating the stone powder slurry b obtained in the step 2; step 4, a filter pressing process: carrying out filter pressing on the slurry c obtained in the step 3; step 5, molding: molding the filter cake d obtained in the step 4; step 6, a drying process: drying the blank e obtained in the step5; and step 7, a firing process: firing the raw brick f obtained in the step 6. The process has the beneficial effects that 1, aggregate stone powder is used as a raw material so that solid waste emission in aggregate production is reduced, and the resource utilization efficiency is improved; 2, clay raw materials required by traditional brick making are not used, clay resources are favorably protected, and cultivated land protection is facilitated; and 3, the molding pressure is large, the compressive strength is favorably improved, and the compressive strength can reach 30MPa or above.
本发明公开了一种石粉制砖工艺，包括以下步骤：步骤一、调浆工序；步骤二、分级工序：将步骤一得到的石粉浆体a进行分级；步骤三、浓缩工序：将步骤二得到的石粉浆体b进行浓缩脱水；步骤四、压滤工序：将步骤三得到的浆体c压滤；步骤五、成型工序：将步骤四得到的滤饼d成型；步骤六、干燥工序：将步骤五得到的胚体e进行干燥；步骤七、烧成工序：将步骤六得到的生砖f进行烧制。本发明的有益效果是：1、本发明利用骨料石粉做原料，有利于减少骨料生产中的固体废弃物排放，提高资源利用效率；2、本发明不用传统的制砖所需的粘土原料，有利于保护粘土资源、有利于耕地保护；3、本发明成型压力大，有利于提高抗压强度，抗压强度可达30MPa以上。
