| 摘 要： | 为了解决大多数粉体混合造粒设备存在对物料的针对性较强或混合设备与造粒设备分离的问题,基于搅拌和揉搓原理,研究开发了双旋转横卧式粉料混合造粒机,阐述了该设备的主要结构与工作原理.以铁粉做示踪物评价了混合均匀度,试验表明:该试验机的混合偏差为2.06%,混合均匀度最高可达到97.94%,混合周期在210 s左右.利用颗粒直径散点图的线性回归曲线斜率评价了颗粒均匀度,在试验时间50～1050 s内,造粒范围为3.89～18.78 mm;在250～650 s内,取样散点线性回归曲线的斜率在0.0644～0.1026之间.混合和造粒试验结果表明该设备对预混粉料适应性强、造粒范围较宽、混合均匀度和造粒均匀度较高、混合周期和造粒周期较短.

| Abstract: | In order to resolve the problems that the most of mixer granulators had the stronger pertinence to materials or mixing equipments and granulators were separated, the horizontal double-rotary mixer granulator was developed based on the stirring and rubbing principles. The main structure and working principle were expounded. In the experiments, iron powder was used as the tracer to evaluate the mixing uniformity. The mixed deviation of the tester was 2.06%, the maximum mixing uniformity could attain 97.94%, when the mixed period was around 210 seconds. The mixed uniformity was evaluated by the curvature of linear regression curve with the particle diameter scatter diagram. When test time was between 50 and 1050 seconds, the granular range was from 3.89 to 18.79 millimeters. When mixed time was between 250 and 650 seconds, the slope of the linear regression curve was between 0.0644 and 0.1026. The mixing and granulating tests show that the horizontal double-rotary mixer granulator has strong adaptability to the pre-mixing powder, and has wider range of diameters of granule, higher mixing uniformity and granule uniformity, and shorter mixing cycle and granulating cycle. |
