Pellets are lens or half-round with 8\u201312% surface moisture before drying. At very high filler the die holes can bridge \u2014 the die heater and knife geometry are what we tune on trial.<\/p>\r\n\r\n<h2 class=\"sec\" id=\"specs\">Reference data<\/h2>\r\n<div class=\"tw\"><table><caption><b>Table 1.<\/b> Water Ring Hot Die-Face Pelletizing \u2014 reference selection data.<\/caption>\r\n<thead><tr><th scope=\"col\">Item<\/th><th scope=\"col\">Value<\/th><\/tr><\/thead><tbody><tr><td class=\"num\">Best for<\/td><td class=\"num\">Filler\/black masterbatch, PE\/PP compounds<\/td><\/tr><tr><td class=\"num\">Output range<\/td><td class=\"num\">200\u20132,000 kg\/h<\/td><\/tr><tr><td class=\"num\">Pellet shape<\/td><td class=\"num\">Lens \/ half-round<\/td><\/tr><tr><td class=\"num\">Watch out<\/td><td class=\"num\">Die hole blockage at high filler, moisture before drying<\/td><\/tr><\/tbody><\/table><\/div>\r\n<p class=\"note\">Reference output measured on the stated material family; subject to a material trial.
