免烘干高强防水工业型煤

High Strength and Water Repellant Industrial Briqettes without Drying in their Production

介绍了ＨＪ系列型煤粘结剂在山东一些煤矿型煤生产中的实际应用情况。该粘结剂原料来源广泛，吨型煤粘结剂成本仅１４～３０元；型煤制造工艺简单，可免烘干；型煤浸水数十天不碎不散，冷、热压强度较高，可满足造气或化肥用煤要求。

Application status of Hj series binder in briqette production at coal mines in ShangDong Province introduced.Raw material for these binders diversified;binder cost being only 14～40 yuan/t briqette.With this technique:briqetting process simplified,no drying process required,briqettes being not disintegrated after soaking in water for several dozen days,both cold an thermal strength of briqette rather high,meeting requirment for gasification.
