Preparation method of aluminum sludge ceramsite
The invention relates to the technical field of sludge waste utilization, and particularly relates to a preparation method of aluminum sludge ceramsite. The aluminum sludge ceramsite comprises following raw materials: electroplating sludge, aluminum sludge, iron oxide and fly ash. The preparation method comprises following steps: stirring raw materials by a stirrer, conveying the mixture into a granulator; then conveying the mixture into a dryer, conveying the ceramsite raw material into a rotary kiln for roasting; grading and screening by a closed screening machine; conveying waste materialsand ceramsite with a size smaller than the standard size to a crushing device by a closed conveyor; forcibly crushing the ceramsite by a crushing device, screening, conveying the powder to a mixed rawmaterial storage tank, weighing the powder by a gauge, and mixing the powder with the mixed raw materials. The wastes are reproduced and utilized, and the prepared ceramsite can be applied to roadbed materials, concrete aggregates and the like, and is wide in application range. The mixed material is formed and made into blocks; after the ceramic manufacturing, the broken ceramsite is crushed, conveyed and recycled by utilizing a crushing device, through advanced processing, the recycling rate of waste materials is increased, and the production benefit is further improved.
本发明涉及污泥废物利用技术领域，尤其涉及一种铝污泥陶粒制备方法，所用原料包括电镀污泥、铝污泥、氧化铁、粉煤灰，通过搅拌机搅拌，再输送到造粒机中，再输送到烘干机中，再将陶粒生料输送到回转窑中焙烧，通过封闭式筛选机进行分级筛选后，废料和小于标准尺寸的陶粒通过封闭式输送机输送到粉碎装置，利用粉碎装置强力粉碎分筛后输送到混合原料的储存罐，并通过计量器具称重与混制原料混合，对废料进行再生产利用，制作的陶粒可应用于路基材料、混凝土骨料等，应用广泛；混制料成型结块，通过对污泥陶制处理完后，利用粉碎装置将陶粒碎料粉碎输送回收，通过进一步加工，可增强废料的回收利用率，进一步提升生产效益。
