Air-Cooled Die-Face Pelletizing Belongs To Melt Pelletizing (Hot Cut). It Means That Melt Comes From A Die That Is Almost Immediately Cut Into Pellets That Are Conveyed And Cooled By Air.
It Is A Process Applicable Only To Non-Sticky Products, Especially PVC. Negligible Amounts Of PVC Compounds Are Transformed Into Pellets.
Melt Pelletizing (Hot Cut)
Melt Comes From A Die That Is Almost Immediately Cut Into Pellets That Are Conveyed And Cooled By Liquid Or Gas. It Is A Process
Applicable Only For Non-Sticky Products, Especially PVC.
This System Includes A Dying Head, Air-Cooling Pelletizer, Air-Cooling Conveyor, And Vibrating Classifier.
The Die Is An Important Part Of The Die Surface Thermal Granulation System. It Is Installed Vertically Or Horizontally And Is Usually Heated By Oil, Steam, Drum, Or Band Electric Heaters. Electric Heating Is Usually Used For Smaller Dies, And Larger Dies Are Usually Heated By Steam Or Oil. Die Structure Materials Have Different Materials, But No Matter What Material Or Heating Medium Is Used, The Diameter Of The Die Orifice Must Be Uniform. The Die Must Have Enough Heat To Maintain The Temperature Of The Polymer During The Entire Extrusion Process, And The Pelletizing Knife Must Be Tough And Smooth Against The Rotating Die Surface. These Are Necessary To Produce Uniform Pellets.
When The Molten Polymer Is Extruded From The Die, A Pelletizing Knife Rotating At A High Speed Cuts It Into Pellets. The Typical Situation Is That The Pelletizing Knife Is In Contact With Or Very Close To The Die Surface. After The Pellets Are Cut, They Are Thrown Away From The Knife By Centrifugal Force. And Transported To The Cooling Medium. The Size, Shape, Material, And Installation Method Of The Pelletizing Knife Can Be Different. In Some Systems, The Pelletizing Knife Has A Spring-Applied Load To Automatically Adjust The Spacing Between The Pelletizing Knife And The Die; While In Some Systems, The Spacing Between The Pelletizing Knife And The Die Must Be Manually Adjusted. Since The Cutter Life Depends On The Accuracy Of The Knife-Die Centering, The Abrasiveness Of The Polymer, And The Aggressiveness Of The Operator, It Is Advisable To Cut Polymer Pellets In The Molten State.
Our Granulator Is Recommended For Polymers That Are Sensitive To Heat And Have A Long Residence Time, Such As Polyvinyl Chloride, TPR, And Cross-Linked Polyethylene. The Pelletizing Rate Is As High As 4989.52Kg/H. The Flow Path Of The Polymer From The Extruder To The Pelletizing Chamber Should Be Kept As Short As Possible And The Minimum Heat Should Be Used. When The Polymer Is Extruded Through The Die, The Rotational Force Of The Rotation Of The Die Surface Cuts It Into Pellets. After The Pellets Are Cut, They Are Thrown Away From The Rotating Knife And Captured By The Forced Circulation Of Air In The Specially Designed Pelletizing Chamber. The Airstream Initially Quenches The Surface Of The Pellets And Takes Them Out Of The Pelletizing Chamber To The Cooling Zone.
The Design Of The Air Duct Reduces The Adhesion Between Pellets.
The Design Of The Flow Channel Is Simple And Efficient.
