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 aluminum cans, PET-bottles, Tetra-Pak, cosmetics etc. when products are either expired, have been incorrectly labelled or for other reasons need to be destroyed.
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 is so dry, that it can be sent to incineration at a lower cost, or it can be sold for recycling. Installing the compactor close to the production helps increase the certainty of destruction and saves a lot of manual handling, as well as transportation and storage
costs.
The SK240 is also suitable for drying reject from plastic washing plants as well as 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 going to incineration instead of ending as expensive and polluting waste at 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 liter Tetra-Pak or 5.000 0,5 liter PET-bottles.
With the SK240 the following densities of the compacted packaging material can be reached:
Alu cans: 400 kg/m3
Tetra-Pak®: 500 kg/m3
PET-bottles: 225 kg/m3
The same machine can dewater many 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 a standard 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 production. The machine separates and compacts in one continuous flow.
- Save space and handling costs through rapid, efficient waste management. Compaction rate of PET-bottles: 8:1. Compation rate of aluminum cans: 20:1.
- Profit from selling the separated liquid and compated packaging.
- Decreasing costs associated with bringing reject to landfill, as it can now be sent to incinaration with a much lower water content. The weight of the waste is also reduced which decreases the transportation costs.
- The amount of manual labor associated with handling the waste can be reduced.
