XMQS 系列真空带筛球磨机采用球磨、筛分一体化设计，粉磨和筛分在筒体内同时进行，凡达到理想粒度的物料被及时筛出，未过筛的粗物料返回筒体内再次被粉磨。特殊的结构设计，密封性能良好，物料过磨性小，产品粒度分布窄，无粉尘污染，具有良好的环保性能。高度密封的磨粉系统与真空泵的组合，能达到 0.09 ～ 0.1Mpa 真空度 , 特别适合稀土、钕铁硼和镍氢电池储氢合金粉加工防氧化、防爆工艺要求。

XMQS  ball mill with screen is so designed as is able to realize both material grinding  and material screening. With it, materials are grinded and sieved at the same  time in the drum. Materials which are grinded into desired particle sizes are  sifted out in time. The coarse materials which have not been able to be sieved  are returned to the drum, to be grinded again. Such equipment enjoys special  structure, good sealing property, fine grinded materials, uniform granular  size, no dust pollution, and good environmental performance. With both the  tightly sealed grinding system and vacuum pump, a vacuum degree of 0.09 ～ 0.1Mpa can be reached. It especially applies to  anti-oxidation and ant-explosion of rare earth, NdFeB, and NI-MH battery, and  hydrogen storage alloys.
