破碎机破碎机

Capacity – How many tons per hour? Efficiency – How many tons per Horsepower?
Quality – Uniformity, fines, oversize
Economics – Cost per ton to grind
加工能力—每小时多少吨？ 效率—每马力多少吨？ 性能—均匀、粉末、过大尺寸
The particle does not “see” a hole, but rather a shortened elliptical opening 碎粒不圆，接近椭圆形
Screen Hole Stagger 筛孔网格
Correct 正三角排布
Direction of hammer travel
经常更换筛子 Replace Screens Frequently
As the screens wear, less material is able to pass through; hammermill capacity and efficiency decrease
当筛子磨损，少量原料能通过时；锤片式 粉碎机加工能力和效率降低

加工谷物、豆粕等易于粉碎的原料时14 – 18 In2/HP 14 – 20 In2/HP for hulls, fiber, tough to grind
加工豆皮、纤维等难于粉碎的原料时14 – 20 In2/HP
Less In2/HP produces a finer grind, more heat 加工好的粉末，热量更高时小于In2/HP
