SpanskRUNI SK240 Screw Compactor -Separation
The Screw Compactor for Dewatering of a Wide Range of Materials
RUNI SK240 screw compactor is the smallest of the RUNI machines that can dewater and separate solids from liquids. The SK240 can dewater expired or wrongly labeled products or any other products that require destruction for whatever reasons. These products include aluminum cans, PET bottles, Tetra-Pak, cosmetics, etc.
When the machine separates, compacts, and creates two waste streams in one continuous process, the liquid is pressed out through a matrix and can go directly into the drain or (if edible) be collected and used for animal feed or sent to anaerobic digestion plants for the production of biogas. The compacted packaging material is slowly pushed out of the exit chute and can easily be collected in containers. After compacting, the packaging becomes so dry that it can be sent to incineration at a lower cost or sold for recycling. Installing the compactor close to the production area helps increase the certainty of carrying out the destruction. It saves costs on manual handling, storage, and transportation.
The SK240 is suitable for drying rejects from plastic washing plants and dewatering wet stickers and labels. Anaerobic digestion plants can also benefit from the SK240 as it can dewater the reject from food waste and squeeze out extra biomass for the pulper. Dewatering the reject with a RUNI SK240 makes the reject dry enough for incineration instead of ending up as an expensive and polluting waste at a landfill.
Which Machine to Choose?
The RUNI screw compactors for dewatering come in two different sizes: The SK240 and the SK370. Which to choose depends on the capacity needed and the size of the material.
The SK240 is suitable for handling packaging sizes up to 1 liter. It can dewater 7.000 aluminum cans containing 33 cl, 5.000-litre Tetra-Pak, or 5.000 0,5 liter PET-bottles.
With the SK240, the following densities of these compacted packaging materials can be reached:
Alu cans: 400 kg/m3
Tetra-Pak®: 500 kg/m3
PET-bottles: 225 kg/m3
The same machine can dewater different materials, but they must be sorted before entering the RUNI if you want to sell the dry packaging for recycling.
The SK240 is available with a standard vertical hopper or conical hopper. Customized hoppers can also be made. The compactor can be fed manually, via a conveyor, or with a tip-container.
Benefits of the SK240:
- Easy destruction of faulty or expired products. The machine separates and compacts in one continuous flow.
- Save space and handling costs through rapid and efficient waste management. Compaction rate of PET bottles: 8:1. Compaction rate of aluminum cans: 20:1.
- Profit from selling separated liquid and compacted packaging.
- Decreasing costs associated with bringing rejects to landfill, as they can now be sent to incineration with a much lower water content. The weight of the waste is also reduced, decreasing the transportation costs.
- The amount of manual labor associated with handling the waste can be reduced.
