DRY PELLETIZING PROCESS BY HIGH IMPACT AND COMPRESSION

Abstract

The high impact and compression dry pelletizing process that the invention proposes focuses its novel characteristics on the fact of obtaining a unified mixture of olefins and conventional polyolefins, recycled plastics, new generation plastics, Biobased, bioplastics, mineral carbonates and/or organic and/or organic fibers and/or synthetic fibers for use in the plastic industry based on compression and temperature, thus achieving greater production capacity, as well as reducing times, materials and space, simplifying these steps by not requiring the tub of water, nor the cutter, in addition, to eliminate the high temperature to melt the materials and mix them and/or formulas.

Claims

1. Dry pelletizing process due to high impact and compression, of the known pelletizing processes to obtain pellets or tablets for the plastic industry, characterized in that the process is dry due to high impact based on compression and temperature, greater pellet production capacity for use in injection, extrusion, thermoforming, blowing and several more.

Description

DETAILED DESCRIPTION

[0007] To complement the description that is being made and with the aim of a better understanding of the characteristics of the invention are accompanied to this as an integral part of it, the following stages of this innovating dry pelletizing process by high impact and compression.

[0008] The process that the invention proposes focuses its novel characteristics on obtaining a unified mixture of conventional olefins and polyolefins, recycled plastics, next generation plastics, bio-based, bio-plastics, mineral and/or organic carbonates, natural and/or synthetic fibers for use in the plastic industry based on impact and compression, achieving greater production capacity, as well as reducing production times, materials savings, energy and space at the production site, simplifying these steps without requiring a tub of water for cooling, nor the cutter, in addition, to eliminating the process the high temperature and energy to melt the materials and mix them.

PREFERRED EMBODIMENT OF THE INVENTION

[0009] The high impact and compression dry pelletizing process is performed by mixing the powdered materials in a high-speed mixer (turbomixer) according to the formulation required to obtain a homogeneous mixture of plastic materials, (Pe, pp, ps, pet, pla, pbta or any other commercial or engineering resin) they are mixed with natural and/or synthetic starches, natural and/or synthetic fibers or natural or synthetic additives or a mixture of all, obtaining a unified and mixed compound at high speed (mixture of lumps); This new compound is introduced to a hopper, in this case, it is required that the materials to be introduced is the mixture of lumps already unified or previously mixed by the high-speed mixer to the pelletizer by compression made lumps, from the hopper it passes to the rollers of high compression and speed, these rollers have the drawing in the desired way, in this case in the form of pellet or tablets, once the product passes through these rollers the (mixture of lumps) is compacted and exits the rollers in the form that they have, in this case, pellet or tablets.

[0010] Subsequently, once the pellet or tablet is obtained from the lump mixture and if required depending on the formula, it is sent by means of bands or gravity to a high temperature dryer which works either by electric energy, gas, biomass or other energy medium, once the dry pellet (mixture of lumps) leaves the dryer, it is packed in sacks, super bags or other selected packaging for storage and subsequent marketing.

[0011] With this process, the compressed pellet or tablet has the same functionality as the pellet of conventional processes, but with a great simplification in the reduction of inputs, space, personnel and costs.

[0012] With this new pelletizing process it can be performed with all types of Plastic and organic material, mainly PE (Polyethylene), PP (Polypropylene), PS (Polystyrene), PLA (Polylactic Acid), PBAT (Polybutylene adipate-co-terephthalate), PVC (Polyvinyl Chloride); Among many other plastic resins.

[0013] In Organic materials we can process, plastic materials with all kinds of natural fibers such as, wood fibers, rice fibers, corn fibers, sugarcane fibers, agave fibers in all its types, among many more fibers. In Mineral and organic materials we can process: CAC03 mineral carbonates, Organic carbonates Sea shells, among many others.
