摘要
煤系伴生高岭岩是煤矿的伴生矿,其中高品质的高岭岩SiO2/Al2O3物质的量比接近理论值2.0,经过煅烧后,可以用来生产莫来石精铸砂.本项目介绍了20万t/a煤系伴生高岭岩煅烧莫来石的工艺及实践,其技术装备先进,采用了预热器、篦冷机等先进技术及装备,煅烧后的产品性能及质量稳定、能耗低,目前已成为国内乃至亚洲规模最大、技术装备最先进的莫来石生产线.
Abstract
Coal bearing associated kaolinite is a coal mine associated mineral,in which the high-quality kaolinite SiO2/Al2O3 material ratio is close to the theoretical value of 2.0.After calcination,it can be used to produce mullite precision casting sand.This project in-troduces the process and practice of calcining mullite from 200000 t/a coal bearing associated kaolinite.The technology and equipment are advanced,using preheaters,grate coolers and other advanced technologies and equipment.The calcined products have stable per-formance and quality,low energy consumption,and have become the largest and most technologically advanced mullite production line in China and even Asia.
