Improved silty clay sintered ceramsite and preparation method thereof
The invention discloses an improved silty clay sintered ceramsite and a preparation method thereof, and the formula comprises the following components in parts by weight: 90-100 parts of low ignition loss silty clay, 0-6 parts of rice bran powder and 15-15.9 parts of water. The preparation method comprises the following steps: step 1, drying the raw materials; step 2, preparing materials; step 3, stirring; step 4, aging; step 5, granulating; step 6, preheating; step 7, roasting; step 8, cooling; the low-ignition-loss powdery clay, a proper amount of cavings powder and water are metered and then fed into a stirring machine to be mixed and extruded, then the mixture is fed into a granulator to be granulated and formed, and the ceramsite is obtained through firing at the temperature of 1175 DEG C, the heating rate of 10 DEG C/min and the constant temperature time of 10 min, so that the strength of the ceramsite obtained through firing is improved, and the ceramsite has the advantages of being good in expansion performance and low in density; and compared with other chemical substances or coal gangue, the method has the characteristics of low cost and good improved economic benefit.
本发明公开了一种改良型粉质黏土烧结陶粒及其制备方法，配方包括：低烧失量粉质黏土、谷糠粉和水，各组分的重量份数分别是：90‑100份的低烧失量粉质黏土、0‑6份的谷糠粉和15‑15.9份的水；制备方法，包括以下步骤：步骤一，原料烘干；步骤二，配料；步骤三，搅拌；步骤四，陈化；步骤五，造粒；步骤六，预热；步骤七，焙烧；步骤八，冷却；该发明，将低烧失量粉质黏土与适量的谷糠粉、水计量后送入搅拌机混合挤压，然后送入造粒机造粒成型，通过温度1175℃，升温速率10℃/min，恒温时间10min烧制得到陶粒，从而提高了烧制得到的陶粒强度，以及具有膨胀性能好，密度低的特点，同时采用的配方，相比掺加其他化学物质或煤矸石，具有成本低，改良经济效益好的特点。
