Plastic recycling grinders<\/strong> is a useful device in any plastics processing plant. They enable the recovery of raw materials from production waste or defective products resulting from injection molding, thermoforming or extrusion. Thanks to properly selected mills, the plant recovers the valuable raw material on its own and uses it for re-production. By implementing the circular economy model, the company gains real savings, reduces the carbon footprint and the negative impact on the natural environment. <\/strong><\/p>\n

In order to properly select a mill and obtain a product ideally suited to your needs, it is worth paying attention to several aspects.<\/strong> It is also good to be aware that by improperly shredding the material, and thus warming it up, we can lead to its degradation, which will make it useless in the next stages of processing. A more accurately selected mill will allow you to obtain a very good quality grinding, without dust. Such a device will also be more efficient, will serve many years and pay for itself quickly<\/strong>.<\/p>\n

<\/strong><\/p>\n

Match the mill to the destination and material you will have!<\/strong><\/p>\n

Depending on the type of material that will be used for grinding, there are two types of devices:<\/p>\n

    \n
  1. Roller mills,<\/strong><\/a> exemplified by the solutions of the French company MO.DI.TEC. They are perfect for hard materials<\/strong> such as ABS, PA, PEEK, PEAK. These are bench mills<\/strong> , used for recycling directly at injection molding machines. Thanks to the wide offer of the manufacturer, the device can be adapted to the type and size of the detail to be ground.\n

    \"MO.DI.TEC

    Roller mill MO.DI.TEC<\/a><\/strong> Series Goliath Plus – energy-saving bench mill with a compact, durable and wear-resistant design with a solid shaft structure. The device is available in various sizes and powers. <\/em><\/p><\/div><\/li>\n<\/ol>\n

    Roller mills work in a slow-<\/strong> running technology which has many advantages, incl. low noise level<\/strong> and no dusting<\/strong> of the ground material. This method of grinding also ensures high quality of the obtained regrind and no degradation of the material. Thanks to this, the obtained raw material can be directly returned in the production process and used to produce further, full-value details.<\/p>\n

    2. The second type of device is the knife mills<\/a><\/strong> of the German company Neue Herbold – designed for grinding soft products made<\/strong> of polyethylene, polypropylene, LDPE, as well as elastomers: TPE, TPU, TPV. Thanks to the rapid rotation of the knives in these devices, the material with a soft texture can be shredded better.<\/p>\n

    The advantages of the Neue Herbold knife mills are also:<\/strong><\/p>\n

    – High processing capacity, thanks to the optimal selection of the geometry of the cutting elements,<\/p>\n

    – Low energy consumption while maintaining high efficiency,<\/p>\n

    – Low proportion of dust,<\/p>\n

    – Placing the knives at an angle to obtain a scissor cutting effect,<\/p>\n

    – Quick and easy knife replacement – adjustment of the rotor and stator knives takes place outside the mill, which significantly increases operator safety and reduces downtime to a minimum.<\/p>\n

    Which mill for the automotive industry and what for the packaging industry?<\/strong><\/p>\n

    So what is the impact of the type of material used on the industry and how to best match the appropriate device to a specific purpose in the company?<\/p>\n

    In the technical and automotive industry, slow-speed mills, e.g. by MO.DI.TEC, definitely prevail. The solutions of this manufacturer currently dominate the market of automotive manufacturers. In the household appliances industry, where a lot of ABS and hard polyethylene are used, slow-speed roller mills are recommended.<\/p>\n
