Simply reliable. Simple installation and set-up Multifunctional unit for discontinuous level monitoring in bulk goods The electromechanical measurement device is an invaluable instrument in the field of inventory management due to its advanced electronics technology. The reliable electromechanical lot system Nivobob® with its robust mechanical design has for that reason become the choice of many plant operators across the globe faced with demanding conditions. The Nivobob® series of plumb bob sensors is used for continuous level measurement within bulk storage silos and also for interface measurement. The simple electromechanical measurement principle is a truly reliable all-rounder in most bulk materials. The sensor weight, made of a suitable material, attached to either a tape or rope is electromechanically lowered from the top into the vessel. Once the sensor weight rests on the material, the winding direction of the motor changes and the sensor weight is rewound to the upper stop position. The electromechanical…

Take a look behind the scenes of RHEWUM on 12 September 2018. Those who are interested in learning more about the separation of bulk solids and the operating principles of screening machines and vibrating feeders, are kindly invited to take a look behind the scenes of RHEWUM on 12 September 2018. As an interest group the German Powder and Bulk Association (in German: Deutscher Schüttgut-Industrie Verband e.V., abbreviated: DSIV) brings together individuals and companies that are working in the fields of production, warehousing, transportation and handling of bulk solids. Since its foundation in 2012, the DSIV has regularly been gathering its members for exchanging opinions and experiences and has also been offering informative professional events. Screening technology plays an important role when processing bulk solids as it significantly influences the quality of the final products. RHEWUM has been planning, constructing and manufacturing screening machines and vibrating feeders at its own site in Remscheid for more than…

Driving with a screening machine on a truck across India? We’re doing it! In April, we started our roadshow across India to show our customers and prospect the performance of our screening machines. The first stage is now behind us and was a complete success. We were able to present our versatile RHEWUM screening technology to 15 companies from the fertilizer, sugar and sand industry. With our WA (U) mobile screening machine, our colleagues in India have not only provided their hosts with theoretical know-how, but have also been able to give hands-on examples of screening fertilizers, sand and sugar, and that’s what counted. In this way, we were able to show one of our customers in the fertilizer industry how he can increase his phosphate screening productivity by 25% without having to change existing processes. With considerable savings in electricity and maintenance costs, as well as a screen purity of around 97% (i.e. in the case of material <150 microns), we exited our customer. Various sand producers also received demonstrations…

Plastic recycling The high-frequency sieve was already frequently used for sieving dust and grit in feed and pet food applications. The desire was to be able to change a sieve deck quickly (<30 sec), but above all to be able to realize a higher sieve effeciency. The machine is then further developed and is now used for plastic recycling, for example, where the machine is placed just before the color sorter. Dust is disastrous for the lenses in a color sorter and so sieve must be sieved thoroughly. The unique thing about this system is that the screen deck can be automatically tensioned and relaxed. It looks like an elastic that attracts you, and causes a larger amplitude when tensioning / relaxing. wedge-shaped flakes, which get stuck in the screen deck, are fired from the deck. Closing the deck is therefore almost impossible. The machine vibrates high-frequency and provides higher sieving efficiency than conventional vibrating sifting machines. This is possible because only…

Support Lockout compliance Lives can be saved during maintenance by placing lockout procedures directly on the relevant machinery and adding tags with contact information on installed lockout padlocks to support procedure compliance. A practical way to do this, is to design tags and procedures in the Lockout Writer app from Brady Workstation and print it with the BradyJet J5000 Label Printer in full colour on reliable materials. Easy to design, print and apply Use the Lockout Writer app from Brady Workstation to quickly create padlock tags and step-by-step lockout procedures. You can also upload pictures and use a standardised template to further strengthen communication impact. Once the lockout procedure or tag is designed, easily print them in full colour on reliable, self-adhesive and tag materials with the BradyJet J5000 Label Printer. Reliable, full colour signs and labels The BradyJet J5000 Colour Label Printer prints full colour safety…

Flour Milling Company in East Jawa, Indonesia It is not unusual for a flour mill to have problems with in-line flap diverters when installed in a pneumatic conveying system. The soft seals around the flap are exposed to direct blast abrasion from grist or wheat flour. This can create significant pressure drops in the conveying system, as well as line plugs once product is allowed to pass through the closed leg of the diverter. A flour milling company was experiencing these problems with the in-line flap diverters purchased when the mill was built. The product leakage from the diverters was creating conveying inefficiencies and significant downtime to uninstall the flap diverter and remove line plugs. The milling company decided to install Vortex Wye Line Diverters, which are ideally designed to overcome common problems associated with in-line flap diverters. The wye line design features a stainless steel sliding blade while maintaining a positive seal when the ports are closed. The diverter is also capable…

RHEWUM sponsors student excursion With the financial support of RHEWUM and other sponsors from the mining industry, students from the field of Raw Materials Engineering of the Technical University Georg Agricola (THGA) traveled about 2,800 km through the sixth largest economy of Southeast Asia. Vietnam is considered one of the emerging economies of Southeast Asia with good economic prospects. Stable economic growth, a relatively cheap and well-educated workforce and political stability offer attractive conditions for investors. With a share of around 6.5% of the gross domestic product, mining is now Vietnam’s fourth-largest economic sector and continues to gain in importance. With the aim to visit mining sites in the northern and central parts of the country, the students of the THGA started their excursion to Vietnam in April. Above all, the focus was on mining of hard coal, apatite, copper, limestone and heavy minerals. To obtain practical impressions, the students visited in addition to the…

Video series about screening and classifying As a specialist when it comes to industrial screeners, we would like to share our knowledge and are therefore starting a video series which answers questions from the field of screening and classifying quickly and comprehensibly. Have you ever wondered why screeners are inclined? Dou you know the differences between dedusting, classifying and protection screening? And what has explosion protection to do with industrial screeners? These questions and many more will now be answered by Mr. Prof. Dr.-Ing. Albert Daniels (Professor of Mineral Resourcing Extraction at the Technical University Georg Agricola) in our weekly published YouTube-Videos. Check our YouTube channel regularly or directly subscribe to our channel at www.youtube.com/rhewumgmbh. Here you can already see what questions will be illuminated in the following 12 weeks: What role does the inclination of the screening machine play? Why does one require different screening machines for different products? What…
