【摘要】：利用實驗室自制小型模擬懸浮態(tài)煅燒裝置和馬弗爐,對菱鎂礦進行快速煅燒試驗制備輕燒氧化鎂,分別對懸浮態(tài)和堆積態(tài)的煅燒產(chǎn)物進行分解率、XRD、SEM、活性等分析,探討兩種煅燒方式對輕燒氧化鎂特性的影響。結(jié)果表明:相對于堆積態(tài)煅燒,菱鎂礦經(jīng)懸浮態(tài)煅燒1 min后分解率即可達到98%以上,得到的輕燒氧化鎂晶粒尺寸小、結(jié)晶度低,比表面積大、表現(xiàn)出很高的活性;懸浮態(tài)煅燒顯著強化了熱傳遞過程,加快了反應(yīng)速度,生產(chǎn)效率成倍提高,產(chǎn)品性能好、質(zhì)量穩(wěn)定,可應(yīng)用于大規(guī)模生產(chǎn)高活性輕燒氧化鎂。
[Abstract]:The light calcined magnesium oxide was prepared by the rapid calcination test of magnesite with a small simulated suspension calcinator and a muffle furnace in laboratory. The decomposition rate and activity of the calcined products in the suspended state and the accumulated state were analyzed respectively. The effects of two kinds of calcination methods on the properties of light calcined magnesium oxide were discussed. The results show that the decomposition rate of magnesite by suspension calcination for 1 min can reach more than 98% compared with that of pile-up calcination. The light calcined magnesium oxide has small grain size, low crystallinity, large specific surface area and high activity. The suspended calcination process has greatly enhanced the heat transfer process, quickened the reaction rate, increased the production efficiency, improved the product performance and stable quality, so it can be applied to the large-scale production of high active light calcined magnesium oxide.
