Die Ein- speisung des Materials erfolgt bei schwer fließenden Pulvern meist mit Zellradpumpen oder Austragsschnecken, bei leicht flie- ßendem Pulver mit Sauglanzen oder Absaugkästen. Bei der Auswahl der Filter in den Fördergeräten ist besonders auf Filtermaterial und -fläche sowie den Abscheidegrad zu ach- ten. Filter und Pulver müssen unbedingt zueinander passen, da andernfalls die Gefahr besteht, dass Partikel die Filter durch- dringen oder dieser verstopft. Gleiches gilt überdies für den zen- tralen Sicherheitsfilter vor dem Vakuumgebläse. ➠ Guill Tool & Engineering Co., Inc. www.guill.com on the tooling, allowing easier and more precise concentricity adjustments without loosening the face bolts. Easy-Out inserts for the adjusting bolts also allow simple replacement of locked or damaged ad- justing bolts, which further saves on re- pair and downtime. Another innovative feature of this new rubber/silicone crosshead is a cast alumi- num liquid-fed cooling sleeve that allows the user to switch out the cooling jacket in the event of a line obstruction, again reducing downtime compared to tradi- tional integrated cooling systems. The NEW 500 Series crosshead with MAGS gum space adjustment is a drop-in replacement on most existing NRM lines, however this crosshead design can also be adapted to fit any extruder design or line layout. The addition of a newly designed flow Guill Tool introduces the NEW 500 Series crosshead with MAGS gum space adjustment. The 500 Series is designed specifically for the flow characteristics and unique processing challenges of elas- tomeric compounds. One of the key fea- tures engineered by Guill on this new crosshead design is the mechanically as- sisted gum space (MAGS) adjustment sys- tem. This new method of gum space adjustment allows the operator to make an effortless adjustment from a single point using a common socket wrench. No more need to struggle with multiple nuts and bolts in order to adjust gum space, which leads to faster adjustments. The vi- sual indicator on the core tube allows the operator to see how far the gum space has been moved, making those adjust- ments much more accurate and repeat- able. The hardware-free and patented cam lock design of the NEW 500 Series from Guill means no time is wasted unbolting and re-securing fasteners for disassembly and re-assembly. Only half of a rotation of the cam nut is required to loosen and automatically extract the deflector from the head body, which is another time saver. Also, with no undercuts on the de- flector, there are no material hang-ups when extracting the deflector, allowing for faster and easier cleaning and changeover. The NEW 500 Series also features the lat- est Center-Stage concentricity adjustment system that significantly reduces pressure New 500 Series Rubber/Silicone Extrusion Crosshead inlet channel reduces the shear and heat that is generated as the materials are being processed. This leads to lower head pressures allowing the material to move through the head in a much more bal- anced and even flow. All crossheads supplied by Guill are fur- nished with a tool kit for assembly and disassembly as well as a detailed opera- tor’s instruction manual. The engineering team at Guill will gladly assist users in the implementation and operation of the NEW 500 series crosshead.
