E3 beaters – efficiency now has a name
E3 stands for economical and energy-efficient grinding. With the new E3 beaters, throughput increases of up to 20 percent compared with existing ACM classifier mill beaters are achieved. As a result of the energy savings, the production costs sink to a minimum. The geometry of the E3 beaters serves to improve the effectiveness of the size reduction process twice over: besides the impact intensity, the impact frequency is also optimised. The inwards-oriented stagnation point flow, which works as a performance obstacle, was minimised. In this way, an optimum energy utilisation of the beaters is achieved. The result: a lower specific energy consumption. The main applications of the E3 beaters are to be found in the grinding of powder coatings and the grinding of tough materials that are difficult to grind such as wax and stearate.
Low production costs, high product quality, uncomplicated retrofitting – all advantages at a glance
The short batch times brought about by the high throughput rate, the low specific energy requirement, the short set-up time due to the wide fineness range of the grinding equipment and the high service life as a result of the speed-dictated low degree of wear all combine to reduce the production costs to a minimum. The E3 beaters also increase the product quality. The fines portion is minimised and even the heat generated during the comminution process and the product contamination brought about by abrasion is reduced.
The investment for retrofitting amortises within one year
The exchange of the old grinding disc for a new one fitted with E3 beaters is simple and guarantees an uncomplicated retrofitting process. No changes to other components are necessary when changing the grinding discs – meaning that the system is fully operational within a very short space of time. Retrofitting can take place on site or by a HOSOKAWA ALPINE expert – dependent on customer requirements. The retrofitting costs of the E3 beaters amortise within one year – an investment which really pays off in the long run.
Precise and uniform processing of metal and polymer powders
HOSOKAWA ALPINE, one of the leading providers in the fields of process technology and film extrusion, has presented solutions for 3D printing at the POWTECH 2019. "The demands in the additive manufacturing sector are steadily rising. In order to do justice to this fact, we have improved and refined several HOSOKAWA ALPINE machines. We can thus offer our customers optimum solutions for the size reduction and classification of metal and polymer powders", says Sylvia Bräunlein, Operations Director of the Chemicals Division of HOSOKAWA ALPINE's process technology business segment.
HOSOKAWA ALPINE ultrafine classifier technology for metal powders in 3D printing
In the additive manufacturing of metal powders, a precise but homogeneous particle size distribution plays a decisive role. HOSOKAWA ALPINE has decades of experience in the development of classifying technologies for different branches. The proven ultrafine classifiers ATP and TSP permit flexible cut points in the range 5-150 μm, and dependent on the requirements, also as a classifying system without filter in circuit-gas mode. The refined TTSP classifier is the only machine on the market capable of realising two cut points for metal powders in one single machine. The top cut and dedusting are accomplished thereby in only one process step.
Ultrafine cryogenic grinding of polymer powders
Ultrafine grinding with an exact top cut as well as the dedusting step are the essential requirements when it comes to the 3D printing of polymer powders. "The Contraplex wide-chamber mill has proven itself in practical operation over many years. And we have now adapted the machine to meet the specific demands in 3D printing", explains Bräunlein. The CW II is characterised by the optimised grinding elements and temperature control, as the result of which the liquid nitrogen and energy consumption is reduced. Tumbler screening machines or air classifiers are employed to
achieve the demanded particle size distribution. The latter, for example, dedust particles that are smaller than 10 – 20 μm and attain a top cut between 70 – 100 μm.
