Description
Technical field
The utility model belongs to grinding attachment technical field more particularly to a kind of variable-pitch auger of large-scale vertical Ball-stirring mill
Blender.
Background technique
Vertical mixing mill is a kind of connected superfine pulverizer, be widely used in metal mine regrind or fine grinding operation in, work
Principle is the stirring action by spiral agitator, so that the abrasive media filled inside Ball-stirring mill and being ground material and stirring
Complicated abrasive action or shuttling movement are done in grinding cylinder, to realize the high-efficient grinding of material, vertical mixing mill is advanced with its
Grinding mechanism, simple structure and process flow, good Operation and Maintenance by more and more be used as ore-dressing technique it is thin
Grind equipment.
Spiral agitator is the critical component of vertical mixing mill, and the energy transmission that it exports motor is to abrasive media and object
Material, structure size directly affect grinding efficiency, and screw pitch is the important feature parameter of spiral agitator, and the size of numerical value is direct
The stress condition of abrasive media is influenced, when screw pitch is larger, helix angle is big, and abrasive media and material vertical velocity are larger, squeezes
It acts on that larger, grinding and peeling effect is smaller, is suitable for the more coarsely graded material of grinding, when screw pitch is smaller, helix angle is small, abrasive media
Smaller with material vertical velocity, squeezing action is smaller, grinding and peeling effect is larger, is suitable for the more fine-graded material of grinding.
Due to the effect of vertical mixing mill gravity classification, coarsely graded material is gathered in the lower part of spiral agitator, particulate
The material of grade is gathered in the top of spiral agitator, and material grade is smaller, to reach identical reduction ratio, and ore grinding energy consumption is got over
Height, the severity of grind needed are bigger；Due to the effect of abrasive media gravity, vertical mixing mill lower part abrasive media and material by
Pressure it is larger, severity of grind is higher, and the pressure that top abrasive media and material are subject to is smaller, and severity of grind is lower, under
It is gradually reduced to upper severity of grind, spiral agitator uses single screw pitch in traditional vertical mixing mill, and which results in spiral shells
The severity of grind that rotation blender top needs the relatively fine particle of bigger severity of grind to be subject to is smaller instead, is not suitable for vertical mixing mill
The middle and upper part material actual conditions different with lower part material size, result in equipment mill efficiency is low and wearing piece uses
