SatrindTech Srl applications
The paper mill waste is the resulting from the recovering process of cellulose from used paper and cardboard. The process is carried out in a pulper that separates and hydrates the cellulose fibers, having as a result a mixture of plastic materials (about two thirds of the total), wood, waste paper, metallic material, gravel and glass fragments.
SatrindTech shredders are used within the recycling lines of refrigerators. When treated properly, it is possible obtains a total of nearly 90% in different materials (among which iron, plastic, polyurethane, aluminum and copper) from these product. The two shaft shredders are used as primary crushers if used as the first step of the process as they are used for a volume reduction after the collecting cycle, while the three-shaft and four-shaft are used as secondary shredding as they allow a controlled size.
This category includes both the wet fraction of MSW (generally collected in the appropriate compostable bags) and all that waste generated by the food industry. If treated properly, this waste can be reintroduced in the production cycle. SatrindTech proposes two-shaft shredders or bag opener for preparing the material for the subsequent steps of separation and composting cycle. If the industrial applications may require a controlled size of the output, the choice has to be fall onto single-, three- and four-shaft shredders These last models, provided with a sorting screen, guarantee the preparation of the material for the subsequent steps of the industrial process.
The oil filters mounted on cars, trucks and tractors, if shredded and properly processed, can return the 97% of the materials. The components which can be recovered are oil, paper, plastics, ferrous materials and not.
This category includes those industrial waste which, due to their physical and chemical characteristics, have to be subjected to special processes to render them harmless before and during the grinding phase. SatrindTech has developed a nitrogen-blanketing system to defuse the possible explosions during the shredding process. Our company propose customized solutions including shredders to 2, 3 or 4 shafts, whether the requirement is to save space and money for logistic purposes and storage.
The paper mill waste is the resulting from the recovering process of cellulose from used paper and cardboard. The process is carried out in a pulper that separates and hydrates the cellulose fibers, having as a result a mixture of plastic materials (about two thirds of the total), wood, waste paper, metallic material, gravel and glass fragments. If crushed and separated properly, this waste is recovered and re-used as a material in the production process or for the creation of RDF. It looks like a deformed twisted dry mass of a steel cable and the recovery operation begins with a volume reduction using a two-shaft shredder.
It’s the so-called Residue Derived Fuel, obtained by treating the dry fraction of the MSW that, after having carefully removed glass, metals and inert, has suitable characteristics to be used as an alternative fuel. The mix of materials are paper (less than 50%), plastic (less than 25%), textiles (less than 15%), organic (less than 15%), wood and other (less than 5%). It is mainly used in cement and steel production plants and energy production plants. SatrindTech proposes two-shaft shredders as primary machines for volume reduction and single shaft shredders, three- and four- shaft shredders for obtaining of a controlled size.
An interesting variant of hard disk shredding consists of the secure data destruction h5 which complies with the DIN 66399-2 requirements. Safe destruction makes it impossible to trace any data contained in hard disks, or similar data storage products, once the storage media has been destroyed. There are many international regulations concerning the safe destruction of documents. They set different destruction methods and levels of security to the required class of protection. This information can be found in our article, which is available by clicking here.
They are all those plastic and textile materials in the car that can be shredded. SatrindTech proposes a two-shaft shredders for volume reduction of bumpers, headlights and three- and four-shaft shredders for shredding automotive interior fabric, sponge and plastic type of synthetic materials.
The drums (from 5 to 220 lt) and the IBCs in HDPE are used for the transport and storage of liquids in countless industrial fields, alimentary and not. The shredders proposed by SatrindTech for this application are two-shaft type in the case of a simple volume reduction, used for achieving an optimization of the logistic processes (resulting in significantly reduce transport costs and material storage once shredded) and single-shaft, three- and four-shaft if the goal is to recycle material discarded from the production line. The two-shaft shredders can also be fitted with the special CL counterblade system that allows a controlled size of the material whilst shredding.
