The EPS pelletizer is a specialized equipment designed for the recycling and processing of waste EPS foam, effectively converting it into granular raw material through a series of process steps. Shuliy EPS pelletizing machine has a production capacity of 150-375 kg/h. This article is mainly about its working principle, parameters, and so on.

What Is EPS?

Expanded polystyrene (EPS) has excellent insulation, heat resistance, shock absorption, and seismic resistance properties, and is widely used as insulation material and product protection material in industrial environments. It has a high recycling value in industrial environments. The Shuli EPS granulator can process various types of EPS foam, including packaging boxes, insulated cups, insulated boxes, takeout containers, and furniture packaging materials. These discarded EPS foam materials usually come from sources such as household waste and logistics packaging waste, which can be recycled and processed into regenerated granules by the foam granulator and used to manufacture new EPS products or other materials.

Structure of EPS Foam Pelletizing Machine

EPS foam pelletizing machine is mainly composed of the main machine, auxiliary machine, die head, grinder, and cooling water tank.

• Among them, the host is the core of the EPS pelletizing machine, responsible for processing EPS particles into plastic strips through hot melt, extrusion, and other processes;
• The auxiliary machine with the host provides the necessary auxiliary functions.

• EPS pelletizer die head is used to form the key components of the particles, its structure and aperture determine the shape and size of the regenerated particles;
• EPS granulator grinder is used to deal with the waste material and the surface treatment of the particles;
• The cooling tank is used to cool down the EPS plastic strips so that it is rapidly to ensure production efficiency and product quality.

EPS Granulator Working Process

EPS pelletizer, as an essential equipment for foam recycling plants, has a simple and efficient workflow. Firstly, the EPS foam is fed into the inlet of the EPS granulator, and the EPS foam is heated to the molten state by the heating system. Next, a rotating screw pushes the molten EPS foams towards the extrusion outlet. At the extrusion outlet, the molten EPS feedstock is extruded through the die head to form pellets of the desired shape, which are cured after cooling. The entire workflow ensures the production of high-quality EPS pellets by controlling parameters such as heating, extrusion speed, and pressure.

Main Features of the EPS Foam Granulator

Outstanding Design:

• Utilizing the automatic design and advanced screw melting technology, the Shuliy EPS foam granulator can efficiently reduce manual costs and improve the plastic recycling process, which reaches up to 375 kg/h, exceeding most similar products in the market.
• The design of the feeding system takes into account the varying densities of materials, enabling customers to have precise control over the feed rate. Additionally, the incorporation of dual reducers empowers customers with effective management of production pace.

High-quality productions:

• Customers can monitor the screw temperature and other operating conditions by the color of the plastic strips, and adjust them through the temperature control box to avoid failure due to excessively high or low temperatures, which facilitates producing more transparent plastic pellets.
• The main and auxiliary machines collaborate to maintain a stable heating temperature, thereby effectively enhancing the molecular structure of the material and improving its permeability. Consequently, there is a significant enhancement in particle quality.
