Polyolefin production includes two distinctive process sections: wet-end process and dry-end phases. The wet-end process can be high pressure or low pressure and the dry-end process consists of 2 phases. Phase 1, called the formulation phase includes primary feeding, additive proportioning, mixing and conveying to an extruder. Phase 2, post formulation phase includes extrusion, pelletizing, conveying, blending, storage and load out systems. The equipment in the formulation phase assists with the primary feed, additive supply, additive feeder refill, additive proportioning and mixing/conveying.
