The Screw Compactor for Greater Requirements

RUNI SK240 screw compactors are the second largest machines for compacting EPS and recommended for an annual volume of 30-50 tonnes. The screw compactor can compact the EPS (also known as airpop) at a ratio of up to 50:1. Before compacting 50 trucks were needed to take the EPS to landfill and now only one truck is needed. The density of the blocks is approx. 350 kg/m³. The compacted blocked can be stacked on a pallet and sold for recycling. 20 tonnes can be loaded on a truck or in a container. TURN WASTE TO VALUE!

Which Machine to Choose?

The material can be fed manually into a 45° hopper or by conveyor belt into a vertical hopper. The pre-crusher placed inside the hopper will cut the EPS into smaller pieces, which falls into the screw. The screw and the automatic hydraulic jaws compress the EPS into the solid and uniform blocks.

The density and size of the EPS is crucial for the choice of pre-crusher. The different incorporated sensors ensure easy operation with the automatic start and stop function and adjustable speed. It is also possible to place the compactor below a silo if you are handling large quantities. The optional automatic block divider and crane ease the handling of the blocks after compaction. The block divider cuts the blocks in predetermined lengths that are fit for easy stacking on a pallet.

Benefits of the SK240:

Save space and handling costs through rapid, efficient waste management.  

Save energy – no heat required in the process. The friction of the screw and the material generates enough heat to make the blocks cohesive.  

Profit from selling compacted EPS for recycling into new PS-pellets.  

The build of the SK240 is airtight making it suitable for compacting dust. An exhaust system is also available for the SK240.  

The amount of manual labor associated with handling the waste can be reduced.

Options for Easier Handling:

Our pre-crusher is available with different configurations and motor sizes. The Heavy Duty Pre-crusher can be fitted for particularly tough and dense materials.

A silo solution is optimal when dealing with large quantities of EPS that needs to be processed quickly.

Automatic block divider that cuts the blocks in lengths perfect for stacking on a pallet.

A crane for moving the heavy blocks from the machine to a pallet.

The SK240 Screw Compactor compacts various materials, e.g. EPS fish boxes and packaging in the ratio 50:1. This achieves a density of about 350 kg/m³.

The RUNI SK240 can be fitted with either a 45 degree, a vertical or a customized hopper depending on the individual requirements. In the movie above we demonstrate the use of a SK240 with a 45 degree feed hopper designed for manual feeding of fish boxes, etc. All SK40s are fitted with hydraulic/electrically-controlled jaws allowing the machine to maintain an almost constant compression pressure.

Power consumption

Primary motor 5.5 kW
Hydraulic pump 0.55 kW
Pre-crusher motor 1.1 kW or 4.0 kW

Capacity

This machine can compact approx. 75 kg of EPS per hour (approx. 110 fish boxes with lids).

Warranty

As with the SK200 and SK370 we offer 2 years warranty or 6000 operation hours, whatever comes first on the machine.
