摘　　要：为提高锤片有筛粉碎机粉碎效率，国内外饲料科技工作者都进行了长期的研究和试验。并对粉碎机的结构做了大量的改进，大多措施仅能提高粉碎效率在5％，15％。要较大幅度地提高，采用定锤减速挡块、开刃锤片和筛面振动配上良好吸风等结构和技术，每项结构的改进均能提高粉碎效率在20％～25％以上。如将所有技术组合配套使用，其粉碎效率可提高到100％。只有把多种有效的技术组合配套使用，具有叠加效应，才能获得最佳的提高粉碎效果。并获得节能、低碳、环保技术新措施，使现有的锤片有筛粉碎机性能获得较大的飞跃，使锤片有筛粉碎机获得新的生命力。To improve grinding efficiency for hammer mill with screen, both domestic and international institution have did long-term research and experiment, making huge amount of improvements, howev- er most of the improvements only improved grinding efficiency around 5%～15%. In order to achieve greater improvement, Stationary Hammer, Edged Hammer, Vibrating Screen technology combined with improved pneumatic system are applied, every technology improved on grinding efficiency over 20%～ 25%. If these technologies are combined and applied together, grinding efficiency can be improved up to 100%. Through the use of a variety of effective technical combination with the superposition effect, the best grinding efficiency can be achieved. Energy conservation, low carbon, environmental protec- tion can be obtained, the traditional hammer mill will have great performance breakthrough and obtain new vitality.
