Research On New Technology Of Hydraulic Grinding And Washing Of Crude Salt

The advantages of water power comminuting and washing raw salt has been approved, for example this technique possess double function that comminuting and washing raw salt at the same time. It not only can simplify the technologic flow, minish environment pollution and improve efficiency of comminuting and washing, but also can decline impurity content of output , improve fluidity , seeming quality and so on. High-pressure water jet comminuting technique as a kind of new-fashioned technique will own broad application and good prospect. It is the finally purport of this thesis to apply this advance technique to our county salt industry as possible quickly as, in order to enhance competition ability of our county salt industry on the world.In this task, we use High-pressure pump(Q=401/min, P-22kw) to provide power for saturated brine. Comminuting device is designed by ourselves. After increasing pressure by High-pressure pump, saturated brine through the comminuting device, in there raw salt is comminuted.In order to ensure the most excellent technical parameters, this thesis presents that one can use the method of orthogonal analysis to study factors how to influence the process of comminuting. Math model about industrialized production of High-pressure water jet comminuting and washing has been founded by taking method of dimension analytical. Furthermore, analysis and forest of model enlargement have been done according to principle of model resemble. It is necessary for further research the technique of waterpower comminuting and washing raw salt.
