EPS Polystyrene Foam granulating line

The EPS polystyrene foam granulating line could process waste foam made of polystyrene into particles. The line includes a granulator machine, water tank, pellet cutting machine, a control cabinet. The main machine is an EPS foam granulator, which includes two machines, combining the functions of crushing and melting.

  • Model: 220+150
  • Power:15kw+5.5kw
  • Capacity:150-200kg/h
  • Double reducer
  • Electric mould as picture(change net without stopping machine)

This foam granulator machine includes a crusher, and a pellet making machine. This EPS foam granulation machine consists of an auxiliary machine, the main machine, a die head, a grinder. It has different types according to the output. Since EPS foam is prone to debris during processing, customers could cover the feed inlet with the cloth.

Water Tank

water tank

This cooling machine is used to cool the plastic pellet and send the pellet to the next step-plastic cutting machine. Customers could also customize the tank according to their demands, but the most common length is 3 meters.

Pellet cutting machine

This machine is used to cut the plastic strip into small pieces and the size of the pellet can be adjusted as your requirements.

Control cabinet

The temperature control cabinet controls the temperature of the plastic pellet machine and also makes people easy to operate the machine.

What are EPS polystyrene foam and EPE styrofoam?

EPS (Expanded Polystyrene) is a lightweight polymer. It uses polystyrene resin to add a foaming agent, and at the same time, it is heated to soften and generate gas, forming a rigid closed-cell structure foam.

This uniformly closed cavity structure makes the EPS have the characteristics of low water absorption, good heat preservation, lightweight, and high mechanical strength. EPS can be molded into shape, that is, it can be pre-expanded into particles, and then formed into various shapes in the mold. It has poor toughness, easy to break, and general cushioning performance.

EPE (Expandable Polyethylene) is commonly known as pearl cotton. The density is small, the flexibility is good, and the recovery rate is high. Excellent shockproof performance, independent bubble structure, low surface water absorption. Good impermeability. It is resistant to acid, alkali, salt, oil, and other organic solvents, and has excellent aging resistance. It does not flow at high temperatures and does not crack at low temperatures.

EPE can be extruded or foamed and can be made into plates, sheets, or pipes, and then punched and cut and bonded to form. It has good toughness, is not easy to break, and has good cushioning properties.
