Single Screw Melter System

Project Overview

Energy efficient, high yield & robust.

Because productivity counts.

The new single screw melter series from PolyReTec defines the benchmark for performance when it comes to the efficient mechanical preparation of post consumer “waste” for chemical recycling.

Particularly robust machines and technologies, the highest flexibility in terms of input material

combined with consistently high melt stability and very low energy consumption throughout

the entire process deliver no-compromise productivity, safety and cost effectiveness.

Energy-saving all-in-one technology concept

Thanks to the high degree of technology integration, several essential process steps are

integrated compactly in one plant, which would otherwise have to be solved using additional,

upstream components. This saves costs both in investment and during operation and makes a

significant contribution to energy and production efficiency.

Main structure and working principle

The machine is primarily composed of a frame, transmission system, air cylinder, feeding hopper, screw conveyor, cooling system, and granulation system. Materials enter through the feed hopper and, under the action of the screw shaft, are compressed through the uneven spiral shaft and perforated plates on the feeding hopper, achieving the dewatering and extrusion effect. Finally, the material is processed into granules or flakes by the blades on the knife frame of the granulation system.

5.The PTW600 pesticide bottle recycling line POLYRETEC.
Pesticides are agricultural chemicals used to prevent pests and diseases and regulate plant growth. They are widely used in agriculture, forestry and animal husbandry production, environmental and household hygiene to prevent pests and epidemics, and industrial products to prevent mould and moths. There are many kinds of pesticides, which can be divided into insecticides, acaricides, rodenticides, nematicides, plant growth regulators, etc., according to their uses. According to the bottle material, it is divided into three categories: PET bottles, pure HDPE bottles and bottles with barrier layers. Many pesticide bottles are produced in farming every year.
