我国工农业生产中的副产品如锯末、棉柴末和秸秆等数量很大,没能得到充分利用而白白浪费,甚至造成严重的环境污染或成为废弃物难以处理。一些经济发达国家如端典、德国和澳大利亚等,利用工农业生产的废弃物压制高密度饼块设备的制造与应用都达到了较高水平,工厂化生产规模较大,压块机主机与辅机配套性好。但由于设备庞大复杂,资金一次性投入大,总配套动力过大,物料和成品集散运输半径过大,所以并不适合我国国情。国内近年来对工农业生产的废弃物利用越来越重视,用稻壳、锯末 The by-products of our country’s industrial and agricultural production such as sawdust, end of cotton chaff and straw are so large that they can not be fully utilized and were wasted, even causing serious environmental pollution or being difficult to handle as waste. Some economically developed countries such as Dian Dian, Germany and Australia, the use of industrial and agricultural production of waste suppression of high-density cake equipment manufacturing and applications have reached a high level, large-scale factory production, briquetting machine host and auxiliary Machine supporting good. However, due to the huge and complicated equipment, the one-time capital investment, the total supporting power is too large, and the collection and distribution of materials and finished products is too large in radiating radius, so it is not suitable for China’s national conditions. In recent years, the domestic industrial and agricultural production of waste utilization more and more attention, with rice husk, sawdust
