1)、物料输入按预期比例分流堆放在一次料场的不同料条的计划堆位上；
2)、物料输出按预期比例将不同品种的物料通过精准控制取料量方式同步取出并合流至物料输送线上，同时保证各物料输送速度满足混合的预期比例；
3)、在料流合流点进行合流打散、料流聚拢，使不同品种物料通过物理方式进行一次匀化；并在料流一次匀化合流点的第一漏斗内设置对向反击积料板，打散料流，改变料流流向，增大不同物料的接触面；
4)、将一次匀化后的输出料流分解为双流程，并进行合流，在合流点处料流进行对向冲击并进行混料作业，使不同品种物料充分混合，得以二次匀化，形成全料料流；并在料流二次匀化合流点设第二漏斗，在其内设置第一分料锥，在第一分料锥下方设双向钩齿式或辊齿式混料机进行混合；
5)、在合流后的输送转运点处设置分料拌料，使不同品种物料进行转运匀化；并在料流转运匀化点的第三漏斗内设第二分料锥，在第二分料锥下方设螺旋式拌料机进行拌料；
6)、在成品外发装料工序设置长型料仓，通过控制仓面布料车往复走行进行布料，使仓内料流形成层叠状，起到匀化。
这样，进厂物料输入采用带式输送机输送至一次料场内不同料条进行分堆贮存，同一个品种可按预期比例分流堆存到各料条内的相应堆位上。物料输出按预期比例将不同品种的物料通过堆取料机精准控制取料量方式同步取出并合流至输送线上。在输出线路上设计为双料流合流布置方式，经过一次合流匀化、二次合流匀化、转运匀化加工处理得到充分混合的物 料，并在末端成品外发装料工序经过布料匀化处理，使物料在粒度及成分上得以充分匀化。
上所述仅为本发明的优选实施例，并不用于限制本发明，显然，本领域的技术人员可以对本发明进行各种改动和变型而不脱离本发明的精神和范围。这样，倘若本发明的这些修改和变型属于本发明权利要求及其等同技术的范围之内，则本发明也意图包含这些改动和变型在内。
