Gala Systems for HMA Production are designed to be cost effective at pellet rates up to 4.550 kg/h. The typical Gala HMA production system will include a vessel, booster pump, melt pump, screen changer, melt cooler / hot oil system, polymer diverter valve with side discharge, water box by-pass system, underwater pelletizer, tempered water system, centrifugal dryer and process control system.
A micropellet is typically around 0.5 mm to 1.0 mm diameter compared to an industry standard pellet size of around 3 mm. Micropellets are often used in rotational molding processes, where the major advantage over powder is the elimination of the two-step compounding and grinding operations. Micropellets are virtually dust free compared to powder. With micropellets being uniform in shape and having a tight distribution, cycle times and/or temperatures can be reduced by using micropellets. Masterbatch micropellets allow very accurate dosing at low rates, good dispersion and easy and efficient clean-up compared to powdered pigments. Additional applications for micropellets include clothing decoration, floor and sports surface applications, toner, insecticide, and more.
Direct crystallization process avoids the use of expensive pre-crystallizers and crystallizers prior to taking the PET pellets into the SSP process or other downstream after-treatment processes. The Gala CPT process complements this process and is superior in method of operation.
Goals of CPT Process:
•Retain sufficient heat in pellets to cause crystallization without additional external heat; •All the free flowing pellets to go directly into packaging or other downstream process
Gala Underwater Pelletizers are frequently used for the continuous and discontinuous production of Polycondensation Polymers (polyamides, polyester, etc.) downstream of a reactor.
Gala provides underwater pelletizing systems for post industrial recycling by converting the recovered scrap back into pellet form. Gala centrifugal dryers are used in large post-consumer scrap conversion, downstream of size reduction equipment and the wash and dry process. Clean, dry scrap can then be re-pelletized.
i-Heat® is a patent pending process that uses gas injection to separate and speed your polymer to the Gala dryer. An inert gas is injected into a key point in the process slurry line. This decreases the residence time and contact time with water, which results in a pellet with most of its internal heat (i-Heat) remaining. This internal heat flashes off moisture, which results in highly improved moisture levels.
