Requirements for the process technology Schönberg, August 2021 From society to politics to industry – everyone acknowledges that a functioning circular economy is necessary to meet climate goals. Everyone also agrees that the use of recyclates must be significantly increased. But there are a number of obstacles and problems along the way. For example, not enough recyclates are available in sufficient quantity and suitable quality. This is due to the fact that recycled plastics are very heterogeneous in composition (type of material, color, foreign bodies). In addition, the prices for recyclate are rising very fast. Innovative process technology is needed to improve profitability and reduce the risk involved in the use of recycled plastic materials. In the new Sesotec White Paper "Using recycled materials in plastics processing" you will learn about … why there is increasing pressure on plastics processors to use more recyclate … the differences between post-consumer and post-industrial recyclate …

Learn more about our radar level transmitters to reliably measure solid and liquid materials in silos and tanks. We have solutions for the most diverse industries. Our radar sensors include a non-contact series NivoRadar® 3000 and a guided wave radar serie NivoGuide®3000 for solis and NivoGuide® 8000 for liquids. Electromagnetic waves form the basis of level measurement with radar. A radar sensor emits a focussed electromagnetic wave that is reflected by objects as an echo and is then evaluated by the sensor. In addition to free-radiating radar sensors, the radar category also includes those based on guided microwave technology, which are referred to as guided radar, TDR (time domain reflectometry) or also GWR (guided wave radar) sensors. The fundamental difference between free-radiating and guided radar sensors is the way the electromagnetic waves reach the medium to be measured. While free-radiating radar sensors use special types of antennas to transmit the waves in the direction of the material without contact, guided radar sensors require a probe (rod or cable) as

For the first time, T&B is preparing a certified protection concept in cooperation with VdS The drying of materials is often the prerequisite for their further processing. The drying process, i.e. the thermal removal of water and other liquids, makes the dried goods durable, mixable, grindable or otherwise usable for further process steps. Drying processes have been industrial standard for many decades already. The first belt dryer in Europe, for example, went into operation as long ago as 1907. These days, belt dryers are used in a wide range of different branches. Examples include belt dryers for timber, pharmaceuticals, food, plastics, wastewater sludge and many other organic substances. All these substances have one thing in common: they are combustible and, in combination with a belt dryer, result in a high fire load. The importance of belt dryers in industrial applications has increased significantly over the past few years. Generally, standard series belt dryers have a modular design. They are made up of a product feeding module, a drying module

Sodium carbonate is difficult to screen as its hydrophilic properties cause agglomerations. RHEWUM’s high quality sieving technology increases production. Soda ash is obtained from sustainable production sources, such as the processing of wood. Soda ash is an indispensable raw material in partticular for the glass industry, but also used as a bleaching agent in the chemical industry and not least in the lye of Bavarian pretzels. The demand for high-quality soda ash is high. The quality of the soda granulate is significantly influenced by the performance, and thus the quality, of the screening machine in use. Soda ash is considered to be a difficult material to sieve, which easily sticks to the screening mesh and tends to form lumps due to its hydrophilic properties. The screening mesh can quickly become clogged and the entire production come to a standstill. Thus, the reliable supply of soda ash for important industrial sectors, and with it the capacity of soda ash producing plants, depends on the screening machine. With the RHEWUM WA, RHEWUM offers a state-of-the-art screening machine with direct excitation of the
