Production of powder for Masterbatch

The outstanding characteristic of this system, the one that distinguishes the mill from others in the market, is the capability to process hard-to-grind plastics such as EVA, ABS, SAN or PA6 without special cooling into high quality powders, for example for masterbatch and compounds. Saving energy does not only start by tweaking the constructive details but also with basic procedural issues. If the materials do not have to be excessively and expensively cooled by means of liquid nitrogen or other cooling agents, if the mill can be cleaned faster and more thoroughly and if more material can be processed in one mill and in quick succession and if the important parameters of the end product can be specifically influenced, considerable energy-, cost- and quality advantages can be achieved.

State of the art of almost any mill available on the market is that the mill can almost only process PE at ambient temperature. The cooling achieved by means of the air flow is not sufficient enough to eliminate the temperature increase incurred during the grinding of other materials and thereby requires the addition of a cooling agent. Most of the time liquid nitrogen is used, which is costly to produce, store and correctly dose. The related expense is reflected in a 5 to 10 Euro cents per kilogram in production costs. These costs can be saved by using a Pallmann Polygrinder Grinding system.

This is demonstrated in the numerous patent protected parts in the mill’s design, which allows for pulverization of difficult materials such as EVA, with an 18 to 20 percentage of VA, without additional cooling. The Polygrinder has mastered a Polypropylene-copolymer, depending on the material composition which almost none of the market available mill can process. In addition to the direct savings as a result of not using expensive liquid nitrogen, the relatively low system complexity also works to save costs.

The pulverization of a wide spectrum of plastics without additional cooling agents and to a defined particle is possible due to the specially designed grinding discs: Instead of a one piece disc the profile section of the machine is made up of key segments, which produce a scissor-type cutting across the entire width of the grinding area. This type of cut also puts less energy –and thereby less heat- into the product. This scissor-cut design is not only gentle to the material but also to the mill: Less wear extends the life of the segments considerably. In addition the segmentation allows for an easy exchange of wear parts, less set-up during re-sharpening and increased safety. The one piece disc in other machines tends to warp during heat treatment and leads to installation difficulties.

Pulverization of PP Copolymer without any cooling nitrogen

In the rotomoulding markets, new applications, end products and materials are increasingly in demand. The PP Copolymer is a result of these efforts. This type of material is used during the production of parts which must perform their services under difficult conditions. Parts made of PP Copolymer are mire impact-resistant in extreme cold conditions, very heat-resistant and dimensionally stable.

These characteristics allow them to be used in vehicle engine compartments and during the manufacture of pressure containers. These moulded parts are also optimally suited for utilization in extreme climatic conditions or for installation below ground level.

In order to produce these products in the rotomoulding process, the PP Copolymer must first be pulverized. Only the production of a high quality powder allows for a defined distribution in rotational moulds. Pallmann, in close cooperation with its customers, optimized a process to prepare this difficult-to-pulverize material, without the addition of liquid nitrogen

Pulverization is performed under ambient temperature. The pulverizing system, type PKMM thereby achieves a high and continuous throughput rate. The evaluation of the results from these trials and comparisons between powder quality, capacity and energy consumption attest the efficiency of the Pallmann process when compared to established cryogenic grinding process. Similar good results are also achieved when pulverizing materials such as PS, PMMA, PC and polyester.

Turn your waste into profit.

The result of a constantly growing world population and increasing industrialization is a permanently rising demand, scarcity and price increase of natural resources. Waste, as a raw material, is therefore more important than ever. The recycling issue gains more and more importance with this background.

Recycling means the reutilization and return of used materials into the material cycle. PALLMANN has been very active in this field for many years now and develops tailor-made and innovative solutions for our customers.

We offer machines and systems for the recycling of:

Useful preparation of post-consumer thermoplastic film waste

Almost any thermoplastic and pre-cleaned waste material, especially from PET-bottles, packaging- and agricultural film can be processed, respectively agglomerated with the PFV-PC.

Worldwide, the amount of so-called post-consumer waste from plastic film, - packaging and –fibers is constantly increasing. In the future it is important to protect the necessary, however limited material resources which are required for the production of these products.  In order to achieve this, it is only logical to recycle these types of material so they can be reintroduced into the recycling process.

For this application, Pallmann has a suitable system, the Plast-Agglomerator, type PFV-PC.
 
The Plast-Agglomerator PFV-PC is able to process pre-cut and pre-cleaned thermoplastic materials with an initial moisture content of up to 10%. The feed material is cleaned in a plastic washing system and afterwards directly introduced into the Agglomerator via a screw press or a centrifuge. They reduce the moisture content of the material to less than 10%. Therefore a cost-intensive upstream thermal drying process is not necessary. The result is a reduction of investment- and operating costs for the system technology. 

The actual process of agglomerate production is performed below the material melting point by means of frictional heat.

Therefore there is no thermal damage and the valuable properties of the feed material are preserved to the greatest possible extent. The end product can be further processed across a range of applications. The performance of the agglomerator can be further augmented by an upstream thermal drying step. Thus throughput rates of much more than 1000 kg/h are achieved with a power consumption of the motor of less than 200 kW. The machine convinces with its compact design and its user friendliness.

Rubber Powders of Finest Qualities

More than 3 million tons of waste tires and a considerable amount of rubber waste are ready to be disposed of annually in Europe. More than 30 percent of this amount are meanwhile recycled. This means that they are not burnt but are mechanically processed. Against the background of diminishing raw materials and the increasing impacts on our environment with carbon dioxide, this is definitely the most efficient manner to deal with waste tires.

 
Mechanical processing, especially the pulverization into finest powders is performed by special machinery. PALLMANN presents the Turbofiner “LYNX”, type PLMW, developed for this application, during the IFAT 2015 in hall C2, booth 117/216. This special pulverization process allows for end product sizing of minus 425 micron. Any rubber tires waste, precut to 2 – 4 mm, or other natural- or synthetic rubber as well as hard to grind or temperature-sensitive products can be used as feed material to be processed.

This achievable, ultra-fine material optimizes the uses of the rubber powder during the production of new tires, as an admixture for insulation boards and rubber products. Besides, it also improves the feel of commodities.

The entire process is performed at ambient temperature. The feed material does not need to be additionally cooled with nitrogen, resulting in the maintenance of the rubber characteristics while achieving greatly decreased processing costs.

 
The precut material is introduced into the Turbofiner “LYNX”, type PLMW by means of a vibratory feeder or rotary valve. Possible contaminants such as metal pieces are preliminarily separated by means of a solenoid coil or an air sifter. Downstream pulverization is performed in the pulverizing chamber by means of material impact at the grinding path and the reciprocal particle impact in the air whirls behind the beater plates of the high r.p.m rotor.  The newly developed beater plate geometry and the high circumferential speed of the rotor in the Turbofiner allow for final particle sizes that have not been achieved with traditional ambient grinding processes. The maximum achievable or desired end product sizing fineness can be determined by selection of the suitable grinding track profile. An adaption to other materials or fineness is also possible at any time.  After the pulverization process, the material is pneumatically suctioned and transported into a downstream filter which separates the powder according to particle size. Material that does not correspond to the desired end fineness is automatically reintroduced into the pulverization process
