STATIC MIXERS - MALIK ENGINEERS MANUFACTURES VARIOUS TYPES OF STATIC MIXERS INTENDED FOR PLASTIC EXTRUFDERS. CONVENTIONAL METHODS OF MIXING USE SPECIAL PROFILES AND ELEMENTS, GROOVES, PINS, ETC, INCORPORATED ON THE SCREW ITSELF AND CAN BE TERMED AS DYNAMIC MIXERS, SINCE THEY ROTATE WITH THE SCREW. THESE STATIC MIXERS ARE MOTIONLESS AND DO MIXING WITHOUT CREATING ANY BACK-PRESSURE. AND ARE PARTICULARLY USEFUL OT EQUALISE TEMPERATURE DISTRIBUTION ACROSS THE MELT STREAM AND TO PROVIDE UNIFORM DISTRIBUTION OF SHEAR EXPERIENCES HBY THE MELT. THE MIXERS ALSO HELP TO ATTAIN UNIFORM DISTRIBUTION OF COLORANTS AND PIGMENTS, DISTRIBUTION OF PLASTICISERS, FIRE RETARDANTS AND OTHER INGREDIENTS IN THE PLASTIC RESIN COMPOUND AND ALLOW INTRODUCTION OF ADDITIVES THAT COULD NOT SURVIVE THE TEMPREATURE AND SHEAR EXPERIENCES THAT WOULD OCCUR IF INTRODUCED AT THE HOPPER OR PART WAY DOWN THE SCRES. THE STATIC MIXERS HELP TO INCREASE OUTPUT OF EXTRUDERS AND THE RESTRICTIONS IMPOSED BY DIES ON THE FLOW RATE OF THE EXTRUDERS ARE ALSO LIMITED AND THE DESIRED PROFILE SECTION IS ACHIEVED OVER A FAIRLY WIDE FLOW RANGE.
