Las causas m\u00e1s comunes son bordes mellados o desgastados, una luz de corte (shear gap) excesiva o desigual, y una condici\u00f3n de criba\/OAR que permite que las piezas \"marginales\" se orienten y atraviesen los orificios.<\/p><h3 class=\"wp-block-heading\" id=\"8f913e69-8e14-4dd3-9d2f-d0aaf39d3c61\">P: \u00bfQu\u00e9 significa \"P98 \u226450 mm\" en el dimensionamiento de CDR\/PDR?<\/h3><p>R: Significa que el 98 % de la masa de la muestra pasa el criterio de 50 mm (dejando solo un 2 % de sobretama\u00f1o en masa).

En la pr\u00e1ctica, lo m\u00e1s importante es la uniformidad a lo largo del ancho del rotor y mantener el valor nominal frente al desgaste y la dilataci\u00f3n t\u00e9rmica: tr\u00e1elo como una tolerancia controlada que requiera verificaci\u00f3n y aprobaci\u00f3n.<\/p><h3 class=\"wp-block-heading\" id=\"32f6bded-1489-47d0-9261-76b095c53674\">P: \u00bfPor qu\u00e9 empeoran los eventos de enredo cuando ajusto la especificaci\u00f3n?<\/h3><p>R: Una especificaci\u00f3n m\u00e1s estricta suele aumentar el tiempo de residencia y la recirculaci\u00f3n. Si la geometr\u00eda, el control de la luz de corte (shear gap) y el equipamiento antienredo no est\u00e1n ajustados para lograr que el material se enganche y corte de forma limpia, el exceso de recirculaci\u00f3n se convierte en un riesgo de enredo e paradas no programadas.<\/p><h3 class=\"wp-block-heading\" id=\"680063c2-4a2f-433b-b7e3-f7c322d22e8b\">P: \u00bfPueden las cuchillas de repuesto para trituradoras (aftermarket) mantener las especificaciones de tama\u00f1o como P98?<\/h3><p>R: S\u00ed, siempre que las cuchillas se fabriquen y verifiquen para mantener el ajuste y la geometr\u00eda requeridos, permitiendo que la m\u00e1quina conserve las tolerancias de dise\u00f1o.
