Vecoplan offers a gentler way to handle waste
Bag opener is energy efficient with low maintenance components; offers new possibilities in reprocessing industry
In order to recycle plastic, metal and composite packaging or household waste collected in bags and put out for collection, the waste needs to be continuously and reliably fed into sorting processes. With the Vecoplan bag opener VSA 250 T, Vecoplan has developed a durable, low maintenance, high throughput yet extremely energy efficient bag opener fit for the job. The machine uses Vecoplan's pioneering drive technology.
The VSA 250 T can be loaded via belt conveyors, shovel grabs or wheeled loaders. What is special about this machine is that it gently opens the bags and empties them. Because the recyclable materials are not destroyed during this process, more material can be recycled - meaning less ends up in landfill. The bag opener's cutting unit consists of hammers welded onto the two rotors, which operate inside the machine's large, open cutting frame. The open design of the cutting frame means the cutting unit is able to cope with extraneous materials such as stones or hand-size pieces of metal. Because the machine only breaks the materials, the subsequent sorting of the reusable, recyclable materials is simplified. With a bulk density of 125 kilograms per cubic meter, the VSA 250 T achieves a throughput rate of 35 tonnes per hour.
The rotors use Vecoplan's dynamic, high-performance HiTorc drives. These are free from mechanical elements such as belt drives, couplings and hydraulic assemblies. They are extremely low maintenance compared to hydraulic drives, which competitor products tend to use. In addition: Because less bulk needs to be moved, the HiTorc has a high degree of efficiency. Vecoplan is therefore able to use versions with a power consumption of just 82 kilowatts – which is lower than in comparable machines. This means significant cost-savings in terms of energy. The drives are fully able to handle extraneous materials. They are highly dynamic and therefore improve the start-up and reversing behaviour of the machine. This makes the bag opener suitable for even difficult, tough materials.
The machine supports are manufactured in a very robust, inert gas shielded arc welded design for holding the rotors and cutting frame. The double side wall on the machine supports prevents dirt from entering the bearing housing. The designers placed a lot of importance on keeping the operating and maintenance costs as low as possible for the machine operators. Wear-resistant, replaceable sealing elements on the rotor and side wall prevent, for example, materials from depositing between the front face of the rotor and the machine housing. In addition: The cutting frame and rotors are replaceable. Time-consuming maintenance tasks such as hardfacing work can be done outside of the machine. This reduces downtimes significantly. Furthermore, the machine is compact and quiet to run.
To ensure reliable operation at all times, the VECO+ Live Service tool is offered as part of the delivery scope. If any faults occur, operators can quickly diagnose the cause online and rectify the error, while also receiving important status messages and production information.
