Processable Materials

  • EPS


Our High Melter series of large-scale EPS volume reduction machines
efficiently reduce the volume of large quantities of styrofoam.
The crushed material is stored in a stock tank by pneumatic conveying,
thereby enabling separate feeding and volume reduction operations.
This eliminates unevenness in the amount of material
received and reduces the time required for a human operator
to be involved in the process.

Recycling Process


Feeding of Raw Materials

Stainless steel feeding conveyor with high rust resistance. The speed can be adjusted to suit the feeding operation. It is also equipped with a function to separate heavy foreign objects.



Styrofoam is crushed evenly and finely to make it easier to reduce its volume. A simple uniaxial crushing system prevents foreign objects from causing blockages. It is also equipped with a function to separate heavy foreign matter.



Finely crushed styrofoam is stored in a stock tank by pneumatic conveying. A full storage of 15 m3is enough for 120 kg of continuous operation.


Volume Reduction

The finely crushed styrofoam is melted with an electric heater to remove air and reduce the volume to about 1/50.

The volume reduction capacity by model is as follows.


Molding & Cutting

Reduced-volume styrene foam is formed into ingots and automatically cut to a specified length before being discharged.

Why Yamamoto?
We're all about making work
safe and comfortable.

While our machines provide unrivalled performance
and create the highest quality ingots,
our real focus is on workplace safety, comfort, and ease of use.

Easy and simple operation
for everyone

Regular operation is simple with the touch of a button. The function monitor allows you to check the supply of raw materials and maintenance information.

Work-Related Stress

The warm-up time is 15 minutes. There is no need to keep workers waiting at the start of work or resuming work after a break. The ingot cooling water is circulated, so there is no need for water supply or drainage, and no need for a cooling system due to natural cooling.

Consideration for the Working Environment

The heat source is small, the odor generated does not diffuse easily, and an activated carbon adsorption type deodoriser is equipped as standard. Also, the crushing hopper is equipped with sound-absorbing materials to reduce noise significantly. These features combine to promotes a more comfortable working environment for the operators.

Designed for

Dangerous parts, such as chains and blades, are covered to prevent access. A safety switch is fitted to stop the machine and prevent it from starting when the cover is open.
An inspection platform is also provided as standard for maintenance of the pneumatic conveyors. This makes it possible to carry out maintenance work safely.

●The E2000 (200 kg/hour) and E3000 (300 kg/hour) are identical in appearance.

●The E1000A (100 kg/hour) and E1500 (150 kg/hour) are a combined version of the E2000 and E3000.


Feeding Hopper

Large capacity of approx. 3.0 m3. Equipped with an inspection stage as standard, which allows safe cleaning of the filters in the pneumatic conveying section.



Electric Heater

Warm-up operation time is 15 minutes.
As the volume is reduced in a short time at a low temperature of 200℃, ingots are formed that are of higher quality and with less deterioration of physical properties.



Molding Section

Expanded polystyrene melted from the heater is formed into the specified shape by rolls and stamps, air cooling with a blower, and water cooling with a molding sink. A cooling water circulation system is adopted to eliminate the need to worry about drainage.



Cutting Section

The wheel sensor monitors the discharge of ingots, and the cutting blade automatically cuts them to the specified length (400, 600, 800, or 1,000 mm).




It deodorises the odour generated at the time of volume reduction by the activated carbon adsorption method and promotes a comfortable working environment.



Function Monitor

An easy-to-understand conceptual diagram allows you to intuitively check the operating status of the equipment and material supply.



Control Panel

Precise and meticulous temperature control is possible. In the event of a problem, the alarm lamp lights up, and a warning sound is made. A message will be displayed on the monitor. The E2000 and E3000 models are equipped with a separate control panel for each system (they both have two volume reducers and two actuators).



Manual Operation Switch

A maintenance switch is located inside the panel. By switching to manual operation, the individual motors can be operated separately, e.g. during maintenance.


Options & Layout Examples

One system type of volume reduction unit [RE-E1000A / 1500]

High throughput and satisfactory cost performance

Two volume reduction systems [RE-E2000 / 3000]

Only one system can be operated in the case of abnormalities or maintenance.

Feeding conveyor + crusher + stock tank + compactor [RE-BC602L4 + RE-SC2001 + RE-T1200W + RE-E2000]

Layout flexibility is achieved through separate the crushing, storage, and volume reduction sections.

Feeding conveyor + crusher + volume reducer + automatic ingot arranger (without stock tank) [RE-BC602L4 + RE-SC2001 + RE-E1000A + RE-HC1000]

This system can be made more compact by omitting the stock tank.
