The paper discusses some issues of fine powders production technologies adjustment. These powders can be used in concrete mixtures for 3D building printers. The work proposes the implementation of vibrational sieves which use the dry method of sifting fine and ultra-fine powders with high performance and efficiency. In this technology, ground material is removed from the mill which prevents the material from consolidation and the grinding process from the slowdown. The paper focuses on a new type of equipment able to withstand overload conditions of up to 30g. It is lightweight, compact, it does not require filters, cyclones, high-pressure fans, sluice feeders. Its sieves do not clog and do not require tightening which considerably simplifies and reduces the cost of operation.
