Description
Technical field
The invention belongs to solid material crushing technology field, especially relate to a kind of high pressure roller mill charging gear.
Background technology
, by the way of attrition crushing, after crushing, ore fine ore ratio is big for high pressure roller mill；But high pressure roller mill is carrying out roller
The stock column pressure that when pressure, between two rollers, mid portion material bears is higher than the stock column pressure of both sides material, and high pressure roller mill edge
The material of grinding roller length direction both sides easily drops from grinding roller two ends without roll-in, and it is thick that this not only causes two ends to run, Er Qiejin
One step reduces the pressure at the extruding force particularly grinding roller length direction two ends of grinding roller, here it is the rim charge effect of high pressure roller mill.
Rim charge effect can not only result in the reduction that integral high pressure roller grinds extruding force, thus reducing the disposal ability of high pressure roller mill, Er Qiebian
Material runs and high pressure roller mill marker size slightly also can be caused uneven, along grinding roller length direction both sides rim charge granularity substantially than intermediate
Material granularity is thicker.In order to solve rim charge effect, material can be solved on feed and naturally drop along the two ends of grinding roller length direction
Problem.
