物料与锤片的线速差和物料通过筛孔的能力决定了锤片粉碎机的粉碎效果

Line speed difference between material and hammer, and material's screen passing ability determine hammermill's grinding effect

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.
