At present, this type of mill has been widely used in coal-fired power plants of China, and its structure is shown in Figure 1. The medium-speed coal mill system is mainly composed of raw coal bunker, coal feeder, coal mill, primary fan, sealing fan, hot and cold air regulating valves. The coal feeder transports the raw coal from bunker to mill ...
PP/MH/RP and PP/MH/RP/CoAl-LDH. When 3 mass% CoAl-OLDH replaced MH/RP, PP/MH/RP/CoAl-OLDH nanocomposites passed UL-94 V-0 rating and the LOI value was high to 27.8%. The cone calorimeter test results indicated that the peak heat release rate, total heat release and total smoke release of PP/MH/RP/CoAl-LDH nanocomposites with …
