Haver & Boecker presents the new generation of CpaServ software at Powtech, in Nuremberg HAVER CpaServ software is the “artificial intelligence” for CPA particle measurement technology. The user interface allows a wide range of measurement procedures to be easily defined and initiated. Measurement and evaluation is then done automatically, with no more intervention by the user. However, if necessary, all data – down to the individual particle – can be reexamined and reanalyzed in many different ways. When developing the CpaServ 2 software, Haver & Boecker again focused on improved ease of use, clarity and efficiency for the user. Customer feedback was very important – and the Haver & Boecker team listened. What’s new this time? Plenty. Inside the analysis software, results and data from a variety of search and sorting functions can now be found faster in almost all areas of the interface. To make both orientation and daily work more efficient, now all major elements have symbols with labeling. Moreover, unused elements can be hidden. Regardless…

Particle Analysis: Sample preparation, measuring, weighing, analyzing Whether using traditional or photo-optical particle analysis – the process for measuring bulk materials should be as simple and yet accurate as possible. At this year’s Powtech in Nuremberg, HAVER & BOECKER presents everything about process optimization in particle analysis. Sample preparation, measuring, weighing, analyzing are simply an integral part of particle analysis. This applies, both, to the classic screen analysis with sieve set and test sieve shaker as well as computer-assisted particle analysis of size and shape of dry, non-agglomerating bulk materials particles. The HAVER particle analysis offers its customers a process chain all of a piece. Generating reproducible sieving results is important with classic sieve analysis. Thanks to the automatic sieve identification and data acquisition from the balance, the analyses are evaluated quickly and reliably with the HAVER CSA software. With photo-optical particle measuring devices, the HAVER CPA 2-1 can…

The new HAVER UFA for test sieving of critical materials under 300 µm. When it comes to particle analysis HAVER & BOECKER offers an extensive range of accessories and peripherals that allow precise and comfortable laboratory work. The HAVER UFA was specially designed for the test sieving of powders involving critical materials with a grain size under 300 µm. The clamping rings are fastened around the sieves to be shaken (for standard sieve diameters of 76.2 mm to 400 mm) so that a transmission of ultrasonic energy over to the test sieve’s screen cloth is enabled. In many cases, compared to classic three-dimensional screening, a significantly improved throughput is achieved through the combination of the laboratory sieve shaker and additional ultrasonic sieving. In some cases sieving is possible for the first time when other processes were needed previously or were not even possible. Sieving time is shortened for most materials because the ultrasonic agitation reduces the friction between the test sieve cloth and the particles. The…

HAVER Industrial Wire Screens When screening loose, bulk materials, and especially when handling abrasives products such as stone, gravel or crushed stone, screen decks are subjected to extreme loads. This leads to more frequent replacement of the wire mesh, which in turn results in undesirable downtime. An alternative is using polyurethane screen decks. Although they have longer lifetimes, they also have less open screen area and so there’s a loss of screening capacity. To compensate for this an additional screening machine often has to be put into operation. One solution offers all the advantages: TY-WIRE Hybrid screening decks combine all the advantages of wire and polyurethane screening decks because TY-WIRE consists of wire mesh that is encapsulated in polyurethane using a special process. The result is a screening deck with a significantly greater open area when compared to conventional PU screening decks. At the same time, they have a lifetime that is 4 to 6 times longer than wire screen…

From MAJOR WIRE Industries Ltd and HAVER & BOECKER Self-cleaning screen media have become the ones to use especially for processing loose, bulk materials. With the FLEX-MAT from our partner company Major Wire, Haver & Boecker now offers a new screening media generation where the design significantly improves the self-cleaning effect. As opposed to the currently available products, the horizontally crimped warp wires are fixed not by weft wires in the FLEX-MAT screen media, but exclusively by recyclable PU connections. In doing so, each wire can individually vibrate throughout its entire length so that caked up material and jammed particles are more effectively prevented. In addition to the high flexibility of the wire, the smooth screen surface provides a considerably longer lifetime when compared to conventional screen sections. Clean: from very coarse to very fine: Self-cleaning screen media up to now have been available with opening sizes of 2 mm to 28 mm and are traditionally suited only for difficult to screen…

Square and rectangular wire mesh cloth The standard is already cutting edge. Haver & Boecker stocks a wide range of standard wire mesh as to ISO 14 315 and ISO 9044, which therefore allows customers to find the right mesh for the job at hand. Square mesh wire cloth. Whenever precise cut sizes for loose materials are required or whenever long particles need to be screened, it is essential to use rectangular opening mesh. For processing coarser loose materials, the type of weaving determines the screening behaviour. Wire mesh pre-crimped on both sides, e.g. DOKA weave and DOKA mesh, causes good rotation of the screened material because of its rough three-dimensional surface. The material has much greater chances of falling through the mesh openings and thus leading to successful screening. Moreover, the fine particles are brought to the screen surface more quickly, which accelerates the entire screening process. The faster the fine particles are screened out, the more screen area is left for screening…

Ultrasonic frequency variation for test sieves from HAVER & BOECKER HAVER & BOECKER offer a comprehensive range of accessories and ancillary equipment for precise and comfortable work in laboratories for particle analysis. The HAVER UFA (Fig.) was especially designed for sieving of powders at critical cuts ≤ 300 µm. The sieve cloth is activated by ultrasonic waves with a continuously varying frequency. These high-frequency oscillations reduce the frictional resistance between particles and sieve cloth. The inclination to blinding is minimized, the sieving capacity is increased and the sieving duration is clearly shortened. Thus, reaching the endpoint of sieving is strongly accelerated by this kind of support and automatic sieving of some bulk solids is only possible at all in this way.
