工业发展模式的转变和步伐的加快对褐煤烘干机生产自动化程度要求增高，褐煤烘干机设备整条生产线大多采用自动化操作模式，输送机送料出料，褐煤烘干机仅需完成对物料烘干作业，在干燥作业时由于各方面的原因所烘干物料难免会混入诸如石子、金属渣、等杂质，这些杂质的性质和着火点与褐煤烘干机烘干的物料并不相同，在不影响烘干物料品质的前提下正确处理这些杂质非常有重要。这时企业客户对褐煤烘干机的选取要求，也是郑州正科机械的研究方向。 目前市场上大多数褐煤烘干机具备基本的除杂功能，不同的褐煤烘干机生产厂家对除杂方式各不相同，一般的褐煤烘干机设备旋转筒内设置对褐煤扬料装置，并在进出料口处安装自动除杂过滤装置。 郑州正科在生产实践中以及客户的反馈中，考虑到
褐煤烘干机的烘干物料形状大小不一，在进料口处安装过滤装置不太现实，只有在出料口处增加过滤除杂装置。我厂的褐煤烘干机筒体内部设有破碎打散装置，比如湿褐煤，进入筒体后经破碎打散烘干后直接经特定的过滤装置过滤后由输送机输送至料仓。具体的除杂工艺如下： 在褐煤烘干机设备旋转筒与过滤筒相连处设有挡板，挡板上开有一小孔过滤筒一端与旋转筒相连，另一端与物料输送管相连，过滤筒内设有挡块底部设有排渣孔，冷却筒一端通过鼓风机与物料输送管相连，另一端与出料口相连。待烘干褐煤物料在进入物料输送管前再次充分散开使水分蒸快速蒸发，挡块可将褐煤物料中的杂质挡住，保证进入物料输送管中褐煤的质量。郑州正科褐煤烘干机节省人力、物力，提高烘干物料的品质，降低了烘干成本，提高企业效益。
Zhengzhou is lignite dryer in the process is introduced Speed up the pace of industrial development model transformation and production increased degree of automation requirements of lignite dryer, coal dryer equipment automation model USES mostly the whole production line, conveyor feed discharging, lignite dryer only materials and complete the assignments, for various reasons when working in a dry drying material will inevitably mixed with impurities, such as stones, metal slag, the nature of the impurities and ignition and lignite dryer drying material is not the same, in does not affect the drying material quality under the premise of the proper handling of the impurities is very important. When enterprise customer requirements, the selection of lignite dryer and zhengzhou is a branch of mechanical research direction. On the market at present most of the lignite dryer has the basic function in removing impurity, different ways of lignite dryer manufacturers for removing impurity each are not identical, general lignite dryer equipment rotating cylinder on lignite coal feed device is installed inside, and on into his
