SCM Ultrafine Mill

SCM Ultrafine Mill

A jet-type grinding mill wherein particles are entrained within a circulating gaseous vortex and triggered to pulverize one another throughout their passage via the mill, the mill having a classifier or separator section wherein you will discover a pair of coaxial tubular nozzles, one particular inside and radially spaced from the other, the two nozzles forming an auxiliary cyclone-type separator signifies whereby the lightest with the ground particles pass via the inner nozzle as final solution whilst the heavier ground particles are recycled back for additional processing.

A classifier section upstream with the grinding chamber

A jet-type grinding mill for somewhat significant particles wherein stated particles are entrained in a gaseous vortex and brought on to pulverize one another in the course of their passage by way of a grinding chamber inside the mill, a classifier section upstream with the grinding chamber, and an outlet in the classifier section, lighter ground particles becoming separated from heavier ground particles in the classification section by centrifugal force, and also the lighter particles passing by way of mentioned outlet by the action of mentioned centrifugal force, a pair of opposed coaxial tubular nozzles within stated classifier section, one of mentioned nozzles obtaining a fairly smaller diameter than the other and getting arranged within said other in radially spaced relation thereto, the nozzle of comparatively smaller diameter being operatively connected to stated outlet and stated other nozzle getting operatively connected to said grinding chamber, mentioned nozzles forming a secondary centrifugal separator within the classification section, whereby the finer particles are drawn in to the smaller sized nozzle although the heavier particles are maintained separate therefrom inside the annular chamber formed among the two nozzles.

A process of grinding comparatively heavy particles

A process of grinding comparatively heavy particles which comprises entraining stated particles inside a whirling vortex of gaseous fluid to cause mentioned particles to pulverize each other under the action of mentioned gaseous fluid in mentioned vortex, initially separating the smaller sized particles resulting from the pulverization in the bigger particles resulting in the pulverization by signifies of centrifugal force causing stratification on the smaller particles on the inner periphery of a circulating stream and on the bigger particles on the outer periphery thereof inside a classifier area and then causing a secondary separation of smallest from much less smaller particles in stated classifier location by subjecting said smaller particles to a secondary centrifugal separation at the center of stated circulating stream when simultaneously subjecting mentioned much less modest particles to a additional pulverization action in the outer periphery of said circulating stream surrounding mentioned center.

A different object in the present invention is always to give a mill of your aforesaid variety

It's, thus, 1 object on the present invention to provide a jet-type mill in addition to a procedure of working with it which is capable of not only adequately grinding or pulverizing coal and comparable components to acquire ultrafine particles but is capable of separating out the ultrafine particles from these of huge size.

A different object in the present invention is always to give a mill of your aforesaid variety that is comparatively uncomplicated in building and uncomplicated to use and maintain.

Other objects and several of the attendant advantages on the present invention will be readily appreciated because the very same becomes superior understood by reference to the following description when study in conjunction together with the accompanying.
