RUNI SK370 Screw Compactor - Separation

SK370 screw compactor with conical hopper for dewatering packaging

SK370 with vertical hopper for AD, RDF, reject or LDPE-film

Compactor for Great Quantities of Trash

The SK370 screw compactors are RUNI's largest machines for separating solids from liquids, and they can dewater various products.

The SK370 is the optimal solution for drying LDPE-film after washing. Using only 20 KW to dry 1 ton of PE-film (the SK370 reaches a moisture content of 5-10% in PE-film), the SK370 is very energy efficient, and often the machine has a quick ROI, as plastic recycling plants can save a huge amount of electricity compared to traditional drying methods.

The SK370 can also be used for drying RDF, which can lower the moisture content from above 50% to below 30 % (depending on the material mix) and increase the calorific value significantly.

Anaerobic plants can also benefit from the SK370. The machine can dewater the rejects from food waste and squeeze out even more biopulp for biogas. Simultaneously, the weight of the reject is reduced, making it cheaper to dispose of and leaving it dry enough to be sent for incineration.

The SK370 can also be used for product destruction at dairies, breweries etc. It can dewater and compact PET-bottles, aluminum cans, Tetra-Pak, and other packaging in one continuous flow. The liquid comes out at the bottom of the machine and can be collected for either animal feed or biogas. The empty and compacted packaging comes out at the end and can be sold for recycling or sent to incineration.

TURN WASTE TO VALUE!

Benefits of the SK370 Model:

Larger screw, more power, more capacity
