PELLETISING SCREW EXTRUDER FOR FORMING CATALYSTS MASSES Russian patent published in 2014 - IPC B29B9/06

Abstract RU 2503537 C1

FIELD: process engineering.

SUBSTANCE: invention relates to extrusion of high-concentration disperse, mainly, thick pastes to produce different-size grains in product of catalysts and sorbents to be used in chemical and food industry, etc. Proposed extruder comprises housing, screw and press tool with multiple forming channels with their axes arranged at 9-16 degrees to acres axis. Forming channels in said press toll are recommended to be made with the help of replaceable polymer composite die carriers.

EFFECT: 1,2-1,5 times higher mechanical strength of extruded pellets.
