A continuous process for fractioning, combination, and recombination of asphalt sources into asphalt components for pelletization of asphalt and asphalt-containing products such that the pellets formed are generally uniform in dimension, freely flowing, free from agglomeration, and the pelletized asphalt is packaged, and preferably compatibly packaged, for additional processing and applications.

A method and apparatus for underwater pelletizing and subsequent drying of crystallizing polymers to crystallize the polymer pellets with out subsequent heating is shown in FIG.. High velocity air or other inert gas is injected into the water and pellet slurry line () toward the dryer near the pelletizer exit () at a flow rate from about 100 to about 175 m3/hour, or more. Such high-speed air movement forms a vapor mist with the water and significantly increases th speed of the pellets into and out of the dryer such that the polymer pellets leave the dryer with sufficient latent heat to cause self-crystallization within the pellets. A valve mechanism in the slurry line () after the gas injection further regulates the pellet residence time and a vibrating conveyor after the dryer helps the pellets to achieve the desired level of crystallinity and to avoid agglomeration.

Method and apparatus for making crystalline polymeric pellets and granules

The present invention relates to a method for enhancement of the minimal shear molding process utilizing pellets and/or micropellets produced through controlled extrusional and pelletization processes in combination with nonpowder melt flow rheology that incorporates reduced molding temperature and/or reduced cure time, reduced rotation axis ratios and/or reduced rotation rates. Molding can be uniaxial, biaxial, or multiaxial rotational or oscillatory or both. The molded items produced can be single or multiple layers and can be produced in one or more molding sequences using similar or different chemical compositions.

Described herein are extrusion processes to produce hollow pellets. Also disclosed are pelletizer devices that can be used to produce the hollow pellets. The processes and devices make use of an extrusion die having a die orifice and an insert that is placed in the die orifice to produce the hollow pellets.

Method and device for extrusion of hollow pellets

A method and apparatus for underwater pelletizing and subsequent drying of crystallizing polymers to crystallize the polymer pellets without subsequent heating is shown in FIG.. High velocity air or other inert gas is injected into the water and pellet slurry line () toward the dryer near the pelletizer exit () at a flow rate of from about 100 to about 175 m/hour, or more. Such high-speed air movement forms a vapor mist with the water and significantly increases the speed of the pellets into and out of the dryer such that the polymer pellets leave the dryer with sufficient latent heat to cause self-crystallization within the pellets. A valve mechanism in the slurry line () after the gas injection further regulates the pellet residence time and a vibrating conveyor after the dryer helps the pellets to achieve the desired level of crystallinity and to avoid agglomeration.

An apparatus and process maintain control of the temperature of low-melting compounds, high melt flow polymers, and thermally sensitive materials for the pelletization of such materials. The addition of a cooling extruder, and a second melt cooler if desired, in advance of the die plate provides for regulation of the thermal, shear, and rheological characteristics of narrow melting-range materials and polymeric mixtures, formulations, dispersions or solutions. The apparatus and process can then be highly regulated to produce consistent, uniform pellets of low moisture content for these otherwise difficult materials to pelletize.

Apparatus and method for controlled pelletization processing

A continuous process wherein polymers or polymeric materials can be subjected to multiple sequential processing systems of differing temperatures and process conditions to synergistically enhance the pelletization and crystallization of those polymers and polymeric formulations, dispersions, and solutions. The multiple sequential processing systems include the processes and equipment for mixing/extrusion, pelletization, multiple transportation processes, crystallization, multiple drying processes, and optional post-processing manipulations of pellets formed. Multiple serial and/or parallel crystallization processing systems are disclosed.

Method and apparatus to achieve crystallization of polymers utilizing multiple processing systems

A self-cleaning centrifugal dryer system and method for removing surface moisture allow complete removal of plastic pellets, flakes and particles from the dryer and water-conveying or water processing system during or after each drying cycle. By eliminating plastic particulate retention in the dryer and throughout the water conveyance and processing systems whereby contamination of different type materials dried during a subsequent drying cycle is avoided. Air and water alone or in combination under pressure are discharged toward various accumulation or occlusion ('hang-up') points in the dryer and throughout the water-conveying or processing system to remove retained plastic pellets, flakes and particles.
