LUDWIGSHAFEN – A suspension is a heterogeneous mixture of substances comprising a liquid and a solid finely dispersed in it. The simplest option for separating out this solid is sedimentation, in which the suspension is left to stand until the solid particles sink to the bottom and accumulate there. The liquid can now simply be decanted, i.e. poured off.
FELTHAM – Industrial powder coating systems have an average transfer efficiency of around 60 percent, meaning 40% of the powder paint does not adhere to the component being powder coated. However, this powder cannot simply be recycled. Due to contamination collected during the spray process, the powder paint collected from the spray booth must be recovered and screened before it can be used again.
WAIBSTADT – The screening specialist GKM Siebtechnik has developed a new generation of pneumatic lifting devices.
FLORENCE, KY – SWECO, the world leader in separation technology, introduces the 3D Metal Printer (3dMP) Screener System. This innovative design collects, screens, and rebottles reclaimed metal powder from 3D metal printers.
LONDON – A Laboratory test sieve is an instrument which is used for the measurement of particle size. In its most common form it consists of a woven wire screen, with square apertures, rigidly mounted in a shallow cylindrical metal frame.
REMSCHEID – The requirements of the premixed plaster industry for the production of up to five sharpsized fractions mean dealing with various processes in order to meet the needs of this difficult to screen material. An Italian manufacturer of different grain sizes for well-known producers of premixed plasters approached RHEWUM with the objective of sizing 80 t/h crushed dolomite flour into the fractions 10.0 mm, 3.5 mm, 2.25 mm, 1.6 mm and 1.0 mm.
HAMBURG – Minebea Intec continues to expand its foreign body detection product range with the introduction of the new X-ray inspection system Dymond Bulk.
REMSCHEID – The prevention of dust explosions is a necessary treatment to ensure the safe operation of sugar plants worldwide. Especially in the field of screening technology only few mistakes can lead to hazardous process conditions. This paper discusses the principles of sugar dust explosions with special focus on their formation. An example is given to show possible threats which can occur during production. Advices for choosing suitable process parameters and equipment are given. A professional dust control is key to decrease the risk of dust explosions.
NUREMBERG – At the Powtech, Goudsmit Magnetics of Waalre (stand 2-450) will show a recently developed magnetic system: the continuous cleaning Cleanflow magnet. This removes both iron and stainless steel from powders and bulk goods and achieves capacities of up to 200 tonnes/hour.
OXFORD, MI – A plastics producer lost many dollars and production time due to weak and leaking magnetic separation equipment in their plant.
