High hardness materi-als become very abrasive; therefore, they are not suitable for high-speed hammer mills. In a typical jet mill, grinding action is caused mainly by particle-particle collisions, so wear to the mill’s internals is less of an issue. 网页2020年2月25日 pulverized coal at the mill outlet is 30%, the gas temperature required at the mill inlet is considered to be approximately 450°C. The evaporation of water in raw coal increases the vapor concentration in the gas at the mill outlet and consequently the O2 level of the primary gas in the burner is expected to be decreased to approximately 9%. 网页2016年7月23日 So I thought of the following solution: Buy a 10-meter PVC pipe of 3mm inner section (outer section is 5mm).
