Preparation method of high-content coal gasification coarse slag lightweight high-strength ceramsite
The invention discloses a preparation method of high-content coal gasification coarse slag lightweight high-strength ceramsite, and relates to the technical field of ceramsite preparation. The method comprises the following steps: S1, pretreatment of raw materials: drying the coal gasification coarse slag, pouring the coal gasification coarse slag into a ball mill for ball milling, sieving the coal gasification coarse slag with a 60-mesh (0.25 mm) sieve, and taking the sieved material for later use; the method for preparing the lightweight ceramsite by sintering the coal gasification coarse slag as the raw material has the advantages that the contained residual carbon can be used as a pore-forming agent and provide heat to reduce the sintering temperature, excessive heavy metal ions can be cured after being sintered at high temperature, and the lightweight ceramsite can be widely applied to the large-market-capacity fields such as buildings, water treatment and soil reclamation. The preparation method is simple, the coal gasification coarse slag can be consumed on a large scale, and the prepared ceramsite has the characteristics of low water absorption rate, low stacking density and high strength, is mainly used for fabricated building materials, thermal insulation materials, sound absorption materials and the like, does not need to add a pore-forming agent, is simple in process, low in raw material cost and low in sintering temperature, and has relatively high economic benefits.
本发明公开一种高掺量煤气化粗渣轻质高强陶粒的制备方法，涉及陶粒制备技术领域；而本发明包括以下步骤：S1、原料预处理，将煤气化粗渣烘干后倒入球磨机中进行球磨，过60目(0.25mm)筛，取筛下料备用；本发明的方法，以煤气化粗渣为原料烧结制备轻质陶粒的优势在于，所含残余碳可作为造孔剂使用并提供热量降低烧结温度，超标的重金属离子高温烧结后可被固化，可广泛应用于建筑、水处理、土壤复垦等大市场容量领域，本发明的方法，可大规模消耗煤气化粗渣，制得的陶粒具有吸水率低、堆积密度低、强度高的特点，主要用于装配式建筑材料、保温材料、吸声材料等，不需添加造孔剂，工艺简单，原料成本低、烧结温度低，具有较高经济效益。
