Technical article: ultrasonic homogenising and blending — reducing small particles in a liquid download
Ultrasonic homogenising is a mechanical process designed to reduce small particles in a liquid so that they become uniformly small and evenly distributed. According to Hielscher, ultrasonic homogenising is said to be very efficient for the reduction of soft and hard particles. The homogenisation is based on cavitation. When liquids are exposed to intense ultrasonication, sound waves propagate through the liquid causing alternating high-pressure and low-pressure cycles.
Heat is used throughout the manufacture of glass, from the heat required to melt the sand, soda and lime, to heat required for tempering and for carrying out many of the processes that are essential to the production of the glass products of today. Infrared heating technology is being increasingly specified to solve heating problems in glass processing stages, providing benefits in terms of cost savings and energy savings. However, the application of infrared systems can also help to ...
The chemical industry is rife with examples of two hazardous chemicals coming together to produce an innocuous and useful chemical, such as chlorine and sodium-producing table salt or hydrogen- and oxygen-producing water. Conversely, when ‘safe’ chemicals are combined, they can produce a hazardous chemical, such as water- and sulphur-producing sulphuric acid.
Ultrasonication is an efficient means for the wet milling and micro-grinding of particles. Besides dispersing and de-agglomerating, the wet milling is an important application of Hielscher ultrasonic devices. Particularly for the manufacturing of superfine-size slurries, ultrasound has many advantages when compared with common size-reduction equipment such as colloid mills, disc mills, jet mills, rotor-stator mixers or high-pressure homogenisers.
The dispersing and deagglomeration of solids into liquids is an important application of ultrasonic devices. Ultrasonic cavitation generates high shear that breaks particle agglomerates into single dispersed particles. As this application note from Hielscher explains, the mixing of powders into liquids is a common step in the formulation of various products, such as paint, ink, shampoo, beverages or polishing media.
There are two aims associated with the optimisation of drying systems. Any optimisation should allow new technical requirements to be realised by the system, such as an increase in the process speed, and it should allow the integration of innovative process improvements. The research results presented in this article from Heraeus Noblelight describe the methodology that should be used to explain the relationship between the important influencing parameters.
This technical article from Hielscher discusses biogas — a byproduct of the decomposition of organic matter by anaerobic or aerobic bacteria that consists primarily of methane, carbon dioxide and hydrogen sulphide. This makes biogas a renewable alternative for fossil fuels, such as natural gas. The article also focuses on ultrasonic disintegration systems and the benefits that their application to the processing of sludge and waste streams results in — including improving the biogas ...
In this paper, Peter Guttridge, chairman of Guttridge, and Ian Walton, chief executive officer at DSH Systems, examine the issue of dust release during bulk material loading, why it happens and the problems it creates. The limitations of conventional equipment are considered within this context alongside the potential benefits of adopting alternative, more modern dust suppression technology. Example data illustrate the cost savings associated with dust suppression.
