Roller Is An Important Part Of Roll Press. The Quality Of Surfacing Wear-Resistant Material On Roll Surface Directly Affects The Use And Maintenance Of Roll Press.
Roller Press Uses The Mechanism Of High Pressure Material Layer Comminution And Adopts The Working Mode Of Single Particle Comminution And Group Comminution To Carry Out Continuous Work. There Are Three Stages In The Operation Of Roller Press: Compaction Stage, Extrusion Stage And Expansion Stage. Compression Stage Is The Most Important Of The Three Stages. In Order To Complete The Grinding Of The Feed Bed, A Sufficient Number Of Materials Must Be Pulled And Pressed Steadily And Continuously Into The Roll Gap (The Narrowest Part) To Grind The Feed Bed (I.E. Extrusion Stage). The Maximum Pressure In The Extrusion Zone Can Reach 200 MPa. It Takes A Lot Of Friction And Considerable Gravity To Pull The Material Into The Zone From Atmospheric Pressure. Moreover, If There Is A Little Fluctuation In The Quantity Or Performance Of The Feed Material, The Pulling Process Will Stop Or The Pulling Quantity Will Be Reduced, Which Will Cause The Fluctuation In Production. If The Material Can't Be Pressed Well In The Pressing Stage, The Most Common Phenomenon Is That The Pressure Can't Go Up During The Extrusion Grinding Operation, The Practical Power Is Low, And The Grinding Effect Is Poor. Selecting The Operating Pressure Of The Roller Press Must Be Appropriate, Too Low Pressure Causes The Roller Press Can Not Play A Normal Grinding Role, And The Effect Is Reduced. However, In Order To Pursue A Good Grinding Effect, Too Much Work Pressure Will Cause Serious Wear And Tear On The Roll Surface Of The Roller Press And Reduce The Operation Rate. Its Biggest Disadvantage Is The Wear Of Roll Surface. It Can Be Seen That Maintaining The Stability Of The Feeding Bin Material Level, Stabilizing The Feeding Volume And Feeding Pressure Are The Necessary Conditions To Maintain The Normal And Efficient Operation Of The Roller Press.
