Compared with similar advanced equipment, FPP Series mill has advantages as follows,① Adding the cutting and grinding function;② Extend the time of material pressing and cutting and grinding;③ Solve the sensitivity of keeping the proportional spacing and proportional thickness;④ Widened material input size;⑤ Material output size are in a perpetual state;⑥ Multifunctional machine is used to dry and grind and filtrate material;⑦ Auxiliary equipment is less and covering is small and investment is small;⑧ Noise is low and dust is small, it is beneficial to protect environment and keep physical and mental health for operation workers.

FPP 型系列磨机的结构形式是电机拖动减速机带动磨盘旋转，带有压力的磨辊在磨盘上自转，对物料进行碾压，磨内的物料在旋转离心力的作用下均匀进入碾磨区，磨辊对物料实施挤压、剪切、研磨，故破碎能力大，粉磨能力强，与同类先进设备相比：①增加了剪切研磨功能；②延长了物料挤压剪切研磨时间；③解决了对物料粉层均匀一致，厚度一致的过于敏感性；④拓宽了对物料的进料粒度；⑤物料的出料粒度永远处于受控状态；⑥可以对物料进行烘干、粉磨、筛分一机多能化；⑦辅机设备少、占地小、投资省；⑧噪音小、扬尘点少，有利于环保和操作工人的身心健康。

The pugging process experiment of silica brick pug was made in Φ1 600×450 wet pan mill to study the change rule of main component mixing homogeneity and molding performance of the pug. The results showed that the pervasion and mixing concurred when diversified materials acceded to the wet pan mill, prolonging time in dry-mixed and wet-mixed periods had no action for increasing mixing homogeneity with pugging time prolonging, the molding performance was improved and the porosity of silica brick adobe had downtrend, but prolonging time after pugging 14 min the effect was not remarkable.

通过对Φ1 600×450湿碾机混练硅砖泥料过程中泥料主要成分的混合均匀度、泥料成型性能的变化规律研究，发现在各种物料加入湿碾机时，同时存在着扩散混合作用，延长干混、湿混阶段的时间，对于提高混合均匀度实际上没有意义；随捏练时间延长，泥料成型性能改善，砖坯气孔率呈下降趋势，但捏练14 min以后继续延长捏练时间，采用正常压制制度时，砖坯气孔率降低值已经很小。
