The Corona pandemic is a wake-up call to improve air quality inside manufacturing plants and other spaces Technological solutions are available for manufacturers to maintain their plant air relatively free of fine dust and viruses. Ulrich Stolz, Head of Technical Engineering at Keller Lufttechnik in Kirchheim unter Teck near Stuttgart, explains how this works, which systems are required, and where it is advisable to use them. Until recently, air pollutants such as coolant and oil mist, welding fumes or dust from machining processes have been the primary focus when it came to the safe filtration of emissions in manufacturing plants. Presently, during the time of the Corona pandemic, the question arises as to whether companies should also protect their employees against viruses, especially the Corona virus Sars-CoV-2, and how to effectively implement this protection. The Corona virus is a largely airborne hazard It is important to know that viruses are microscopic in size. They measure only 20 to 330 nanometers (= thousandths of a micrometer, μm). According to current…

FM Conway got first prize at this years MPA (Mineral Producers Association) awards ceremon FM Conway was awarded first prize at this years MPA (Mineral Producers Association) awards ceremony last night. This was an Innovations award for Health and Safety and environmental technology. They won the Award with the Cleansky Asphalt technology (Odour System) designed and installed by Luksal at an FM Conway Asphalt plant in the neighbourhood of Heathrow Airport. There was a total of 134 innovations submitted by the industry combined (including all the big players in the Asphalt industry) and FM Conway won!!!!

Foundry KUTES Metal in Turkey places its trust in EIRICH molding material preparation EIRICH has been able to deliver several molding material preparation systems. As well as improving the quality of the cast parts, this also helps to increase plant availability thanks to the comparatively low wear on the mixing tools. KUTES Metal has now also decided to opt for an EIRICH molding material preparation system for its new production line. Claybonded molding material is used primarily in the production of cast parts. There are a large number of parameters that impact on its suitability for use, including com-pactability, gas permeability and green strength. Only the use of optimized molding material can ensure fault-free cast parts. This means that the preparation of the molding material plays a central role in the process. In this preparation process, sand is mixed with bonding clay, additives and water. Through the addition of water, the bentonite swells up and exhibits adhesive strength. The water content has a large impact on the plasticity and therefore…

The EZD in selb is an interdisciplinary center, that was established to undertake development work in the ”production and characterization of dispersions”. The EZD has supplemented its fleet of machines with an Eirich evactherm® dispersion mixer. The R&D areas cover the entire spectrum, from additive production to dispersion to non-destructive testing. Activities relating to dispersion (formulation, analysis and dispersion techniques) are now exclusively bundled at Selb. The relevant services are offered for a wide range of sectors and applications, such as paint and coatings, nanocomposites, adhesives and matrices for fiber-reinforced composites. The laboratory facility needed for this is accordingly equipped for a wide range of tasks. Recently, this equipment has been supplemented with EIRICH processing technology: a 1-liter vacuum mixer with an EX-protection finish, 4 kW drive power, with an accompanying condenser, vacuum pump retort and fully-automatic touch-panel…

Increased service life with reduced energy consumption For many years, Keller has been committed to a better living environment under the label “Green Balance”. Keller builds efficient dust filters with the lowest emissions which make a significant contribution to the environment. Keller also wants to reduce the ecological footprint of dust filters. After launching the Vario ECO filter appliances, Keller now continues with a new generation of Keller filter elements: the KLR-filters-Keller Long Run. The new KLR-filters have a guaranteed service life of 18,000 hours or 3 years equivalent to 120,000 cleaning intervals, a true record! In this way, Keller ensures a longer life cycle of the filter elements and less waste. In addition, the energy consumption of the filter elements is 5% lower which reduces not only CO2 emissions but also provides a cost saving. By this, Keller continues the tradition as a leading supplier of dust filters and proposes its customers the latest filter technology available. You can…

Eirich preparation technology for the recycling of dusts containing valuable material In many industries dust containing materials which can still be reused is generated along with the exhaust gases involved. In the metallurgical industry, for example, these can be metals and metal compounds. To recover these materials the dust has to be agglomerated. Depending on the specific application this is achieved by granulation, pelletization or even compaction/briquetting. The use of Eirich preparation technology offers advantages for all applications. In virtually all cases the agglomeration process is preceded by a mixing process. This is because, first, the self-moisture of the dust alone does not provide sufficient compactability; second, other materials – e.g. carbon carriers – often have to be mixed in as well. This is why liquids and additives are also admixed in a mixer, often along with binders as well. As a general rule the volumes of dust requiring processing are very large. It is therefore desirable to use as little binder as possible. In…
