From a 1 m3 cubitainer to 50mm chips, using a two-shaft shredder? With SatrindTech, “sí, es posible!”

A Spanish manufacturer of HPDE cubitainers and containers based in Cataluña has chosen SatrindTech to implement its recycling line of defective cubitainers.

The request received by our Sales Department was to replace an existing SatrindTech twin-shaft shredder, in use since the mid-1990s, to now be able to ensure a regular size of the shredded material.

The cubitainers are HDPE containers of approximately 1 cubic meter of volume that, inserted in a metal cage, are used in a wide variety of industrial sectors (oil+gas, food, medical and chemical sector, just to name a few) stocking and handling liquids or juicy materials.

The model purchased by the customer is a two-shaft shredder of the K 25 HP series equipped with 50mm blades at four picks (/hooks), a 1000 mm shredding chamber and completed with our patented CL system.

This counterblade system, patented by SatrindTech, enables conversion of a dual-shaft shredder model, with which it is normally only possible to perform volumetric, and therefore irregular,  reduction of the processed material in a machine capable of shredding materials with a pre-defined size.

A fixed counterblade located under the blades, together with grilles under the shredding chamber of the machine, allow a continuous process of material shredding so that it can be expelled from below upon reaching the required size.

Cubitainers are a type of material for which it is advisable to use a special hopper, called angular, so that material, with its typical cubic shape, can slide inside the machine at an angle of 45° from the centre distance of the blades, thus facilitating gripping by the blades.

The configuration selected by our customer will allow them to process one cubitainer per minute, obtaining a final size of the product being processed of approximately 50 x 50 mm.

Further information on the CL system is available by downloading the relevant technical data sheet here. Use this link to watch the example video.

Our shredding solutions speak American

Our client is an American multinational corporation in the plastic sector with offices and production plants in 23 countries and over 35,000 employees.

The client’s need to improve its performance in recycling material waste, whereby they currently only use one material granulator, led SatrindTech to suggest using two twin lines to handle plastic material in PPE. One line will be used to reduce the volume of sprues, while the other will be used to process waste from the plant’s extrusion line.

The engineering of the line consists of three elements: an automatic hoist tilter, a dual shaft shredder (model: K 8/25) and a transport belt placed after the shredder to transport the shredded material to the mill.

The process provides a total automation of the process for the cargo and discharge of material, whereby cargo is carried out by placing the material cargo into the hoist tilter which will lift and carry the material into the hopper. Once the material has been shredded in the shredding room, it will be transferred to the mill using the transport belt. The whole process cycle is managed by a PLC Siemens control panel.

While this solution is in itself a solution that has already been tried and tested during SatrindTech’s history, its uniqueness lies in the fact that the main electrical panel that governs the plant was designed and uses components in accordance with UL 508 / NPFA 79. Therefore, the electrical panel had to be completely redesigned, in keeping with IEC standards, for the use of components that respected the UL standards, as the on-board wiring had to reflect the similar requirements. All of the electrical cables had to be reviewed and replaced in keeping with European standard supplies.

In essence, this legislation regulates the provision of equipment and instructs the technical characteristics which the machine(s) must possess for the United States. Where the certification, in accordance with these regulations, is a contractual requirement, the SatrindTech and its Engineering are able to satisfy any such problematic requests.
