sprinG loAded pelletizer MAnUAllY AdJUstABle pelletizer electronicAllY AdJUstABle pelletizer (eAc) The Manually Adjustable Pelletizer (MAP) features a manual adjusting wheel to position the blades against the die plate. This simple blade adjustment design provides visual blade wear indication and maximum control of blade position. The Gala EAC Pelletizer offers fully automatic control of blade adjustment, positioning and monitoring, resulting in maximum blade and die face life. The unique design of the axial advance system replaces the need for a bearing housing assembly. The MAP design...

process scheMAtic The process schematic shows the flow of resin through a Gala Underwater Pelletizing System. Material is fed into an extruder or melt pump, which forces the molten polymer through a screen changer and/or polymer diverter, then through the pelletizer die plate. As the polymer emerges from the die, pellets are cut by rotating blades and are solidified by the process water flowing across the die face inside the cutting chamber. The process water transports the pellets to a dryer-86120.html">centrifugal dryer where the water is removed and the dry pellets are discharged. The process water is...

GAlA direct crYstAllizAtion process technoloGY An exciting development for the industry and specifically for crystallizing polymers is the Direct Crystallization Process. This process avoids the use of expensive precrystallizers and crystallizers prior to taking the pellets into the SSP process or other downstream after-treatment processes. The direct crystallization process offers two energy reducing elements. It retains sufficient heat in the pellets to cause the polymer to crystallize without any additional external heat required. It also allows the free flowing pellets to go directly...

COMPONENTS OF THE PELLETIZING SYSTEMS die plAte The die plate is the heart of the Gala underwater pelletizing system. All Gala dies are custom designed to fit each customer’s specific polymer requirements. The material of construction and wear face material are determined by the specifications of the Customer’s application. All die face surface materials provide maximum wear life before resurfacing is required. MUlti-zone die plAte heAtinG A significant advancement in Gala’s underwater pelletizing technology is the multi-zone die plate heating concept which provides local heating Gala’s...

cUtter BlAdes cUttinG chAMBer d2 is the material of construction known as the benchmark of the industry. This material will usually get the job done at a low price. The primary element is 12% Chrome which gives the blade good toughness and rust resistance. The cutting chamber is the housing in which the pellets are actually cut. The pelletizer is coupled to the cutting chamber, which places the cutter 440A Stainless Steel (available on special request only) has an 18% Chrome content and is part of the stainless steel family of tool steels. This is the best tool steel offering for knives...

COMPONENTS OF THE PELLETIZING SYSTEMS polYMer diVerter VAlVe (podV) The polymer diverter valve is used to direct the polymer melt from the pump or extruder to the floor, to the side, or directly into the die plate. This is an indispensable function during start-up for difficult products that are sensitive to temperature fluctuation. In underwater pelletizing, an optimized volume flow per die hole must be ensured right from the start. Most of the upstream equipment responds rather slowly, e.g. ramping up of the extruder. The polymer diverter permits a controlled start-up of these upstream...
