    • A process for generating a non-spherical shaped particles comprising the steps of: extruding a material through an extruder nozzle orifice along an extruding axis, and. slicing the extruded material into extruded elements having a predetermined length (L). Wherein the temperature at the nozzle is kept at a temperature Tn, where Tn = Tm - T, and T is greater than about 20 C, Tm being the melting temperature of said material. Where said extruder nozzle orifice has a predetermined cross-sectional shape on a plane perpendicular to said extruding axis, said predetermined cross-sectional shape being the inverse image of the predetermined cross-sectional shape of the extruded elements, wherein said non-spherical shaped particles comprise elements having a longitudinal length (L) where the ratio of said length (L) to a perimeter-equivalent diameter of said predetermined cross-sectional shape "ECD P Hull " is between about 0.5 and about 5.
    • 一种用于产生非球形颗粒的方法,包括以下步骤:沿着挤出轴线通过挤出机喷嘴孔挤出材料,以及。 将挤出材料切成具有预定长度(L)的挤出元件。 其中喷嘴处的温度保持在温度Tn,其中Tn = Tm-T,并且T大于约20℃,Tm是所述材料的熔化温度。 在所述挤出机喷嘴孔口在垂直于所述挤出轴线的平面上具有预定横截面形状的情况下,所述预定横截面形状为挤出元件的预定横截面形状的倒像,其中所述非球形颗粒 包括具有纵向长度(L)的元件,其中所述长度(L)与所述预定横截面形状“ECD P Hull”的周边当量直径的比率“ 在大约0.5和大约5之间
