The Process of Sedimentation of Solid Particles of the Grinding Sludge

Abstract


 
 
 Thousands of tons of grinding slimes are formed every month at the mechanical engineering enterprises (especially at bearing plants) and metallurgy ones, which are processing metals. Slimes are practically not processed at present, but exported to special landfills or dumps, worsening the environment. Slimes of abrasive metal processing can be a raw material base for powder metallurgy, as they contain 60-80% of metal particles. It is necessary to carry out the solid particles separation by density process at the slimes washing stage to increase the homogeneity of metal powder, which is extracted from grinding slimes of abrasive metal processing. The fluid flow consumption through the vertical nozzles, which allow keeping solid particles in a suspended state, is determined in this work on the basis of theoretical studies of the solid particles deposition process of grinding slimes.
