就滚筒烘干机而言，其热源设备一般都是直接式热风炉。采用该热风炉可将高温烟气送入滚筒烘干机筒体内部，使筒体内温度升高（筒体******温度在800℃左右）。 如果您要烘干的物料要求更高的温度，需要提前告知生产厂家，技术人员在设计烘干机时会考虑机器材质的热承受能力。 如果您要用滚筒烘干机烘干粒状物料时，烘干机在烘干这些物料时由于温度过高导致导致粒状的高炉矿渣发生重结晶而会失去水硬活性。正科在使用烘干设备的时候物料的烘干过程中应该针对物料不同的水分和物理特性的要求来确定其所需要的烘干的温度，这样才能够不至于引起物质的变化，从而影响到产品的质量。在此，郑州正科建议您在选择滚筒烘干机先将自己的实际情况与我厂技术人员交流一下，他们会为您设计符合您要是的新型设备。有关滚筒烘干机热风炉的选择，烘干机价格、烘干工序、烘干方案等问题可咨询在线客服或拨打24小时服务热线

When buying a drum dryer, the choice of hot blast stove should be cautious  in terms of drum dryer, the heat source equipment are generally directly type hot blast stove. Using the hot blast stove can be incorporated into high temperature flue gas inside the drum dryer cylinder, the cylinder body temperature (cylinder maximum temperature at about 800 ℃). If you want to dry the material demand a higher temperature, the need to inform the manufacturer in advance, technical personnel in the design of the dryer can consider material heat capacity of the machine. If you want to use the drum dryer to dry granular materials, the dryer during drying these materials cause of granulated blast furnace slag due to high temperature recrystallization and hydraulic activity will be lost. Material is division in the use of drying equipment drying process should be aimed at the requirement of different moisture content and physical characteristics to determine its need drying temperature, so that can not cause the change of the material, which affect the quality of the products.
