EPS Polystyrene can be densified using a foam densifier, which is a machine that crush and melts expanded polystyrene (EPS) foam into denser, more manageable blocks or ingots. Here are the general steps involved in densifying polystyrene using a foam densifier:

 

Collection: Collect EPS foam waste, such as packaging material or insulation, and separate it from other waste streams.

Pre-processing: Remove any contaminants such as labels or tape from the EPS foam waste, and break it down into smaller pieces or beads to help it feed more easily into the densifier.

Feeding: Feed the EPS foam waste into the foam densifier using a conveyor or other feeding mechanism.

Compression: The foam densifier compresses the EPS foam using a combination of heat and pressure, reducing its volume by up to 90%.

Melting: The compressed EPS foam is melted by heating it to a temperature of around 180-220°C, depending on the type of foam and the densifier being used.

Extrusion: The melted EPS foam is extruded through a die to form blocks or ingots of densified polystyrene.

Cooling: The densified polystyrene blocks or ingots are cooled using water or air.

Storage: The densified polystyrene blocks or ingots can be stored or transported for recycling or disposal.

Foam densifiers can come in different sizes and capacities, and the specific steps involved in densifying polystyrene can vary depending on the type of densifier being used.
