The invention discloses tunnel kiln fired concrete aggregate and a production method thereof.The tunnel kiln fired concrete aggregate is prepared from shale, coal gangue, peat, clay, sludge and industrial waste residues, and the concrete aggregate is fired through seven steps; the shale, the industrial waste residues, the clay, the sludge, the coal gangue, the peat and other raw materials are matched and sintered to generate the composite aluminate and other minerals to form the high-strength compact building aggregate, the nearby material selection range of factory raw materials is wide, theindustrial waste residues can be digested and treated, and environmental protection is facilitated; inferior fuel with low calorific value is used as internal combustion fuel, so that the fuel production cost is greatly reduced, and energy is saved; the tunnel kiln is adopted to calcine the building aggregate, the process is simple, the production operation is reliable, a DCS control system is added to form a stable thermal regulation, the product quality is stable, the yield is high, the application range of fuel is wide, kiln tail waste gas is used for drying, crushing and grinding of raw materials, the unit energy consumption is further reduced, the investment is small, and the income is high.
本发明公开一种隧道窑烧制混凝土骨料及其生产方法，包括由页岩、煤矸石、泥煤、粘土、污泥和工业废渣组成，经七个步骤烧制混凝土骨料；本发明利用页岩、工业废渣、粘土、污泥、煤矸石和泥煤等多种原料配合烧结生成复合铝酸盐等矿物形成高强密实的建筑骨料，工厂原料就近选材范围广，且可以消化处理工业废渣，利于环保；使用发热量低的劣质燃料作为内燃燃料使用，极大地降低了燃料生产成本，节约能源；采用隧道窑煅烧建筑骨料，工艺简单、生产运转可靠，再加DCS控制系统形成稳定的热工制度，产品质量稳定，产量高，且对燃料的适应范围广，窑尾废气用于原料的烘干破碎及粉磨，单位能耗进一步降低，投资少且收益高。
