Method for preparing artificial agglomerated stone by recycling sludge of artificial agglomerated stone
The invention discloses a method for preparing artificial agglomerated stone by recycling artificial agglomerated stone sludge, and belongs to the technical field of calcium carbonate preparation. Themethod comprises the following steps: collecting agglomerated stone waste residue, and evaporating surface moisture; conveying the primarily dried materials to a thermal power plant in a centralizedmanner, and drying the agglomerated stone sludge by utilizing steam waste heat of the thermal power plant; and adding a modifier and a coupling agent, conducting grinding and grading by using a ball mill to obtain the recycled calcium carbonate powder for the artificial agglomerated stone, and producing new agglomerated stone by using the calcium carbonate powder as a production raw material of the artificial agglomerated stone. The method provided by the invention is simple in process, the artificial agglomerated stone sludge can be recycled to prepare the new agglomerated stone, and the problem that the agglomerated stone waste residue sludge is difficult to treat over the years is solved.
本发明公开了一种人造岗石污泥回用制备人造岗石的方法，属于碳酸钙制备技术领域，该方法包括以下步骤：收集岗石废渣，蒸发表面水分；将初步干燥的物料集中运送到火电厂，利用火电站蒸汽余热烘干岗石污泥；加入改性剂、偶联剂后用球磨机进行研磨分级即得回用的人造岗石用碳酸钙粉，作为人造岗石的生产原料生产新岗石。本发明提供的方法工艺简单，可以让人造岗石污泥回用制备成新岗石，解决了多年来岗石废渣污泥难处理的问题。
