Versatile Mixer for Chemical and Thermal Processing

Ifat 2020 Versatile Mixer for Chemical and Thermal Processing

2020-03-09Editor: Ahlam Rais

Lödige Process Technology will present a Ploughshare mixer at its Ifat booth (A4.441) in Germany. The mixer is an example of the manufacturer’s sturdy, durable process engineering systems for mechanical, chemical and thermal processing of sludges, sewage sludges, ashes, dusts and other waste materials.

Ploughshare mixers are based on the mechanically generated fluidised bed process patented by Lödige. This process involves Ploughshare shovels rotating close to the walls of a horizontal, cylindrical drum. The mixers are available for both batch mode and continuous processes.

The continuous mixers of the KM series are particularly suitable for environmental engineering applications, states the company. This low-maintenance mixer model is intended not only for processing powders, fibrous or granular solids, but also fluids and pastes. The continuous mixer even performs granulating processes with minimum retention times. According to the firm, it is characterised by excellent repeatability, maximum homogeneity of the final product, short retention times and great economic efficiency.

The sophisticated mixer concept also includes universal applicability of the machine. Beyond processing of dry, powdered, granular or fibrous solids, it can also be equipped for numerous other mixing tasks. Adding fluids to moisten product components is just as possible as processing pastes and fluids.

Specialist Book „Heat Transfer Technique“The comprehensive standard work „Heat Transfer Technique“ offers not only a detailed and well-founded presentation of the basics of heat transfer technique, but also shows the latest state of the art and the latest regulations in the use of organic fluids. Thematically, the book is rounded off with an overview of property data of organic heat transfer fluids as well as many use cases from practical experience.

Moreover, installation of choppers in the mixing drum permits breaking up of agglomerated material as well as systematic granulation during the mixing process, adds the firm. A heated and cooled drum, head pieces and shaft are also among the available equipment options.

If the machine is subject to particular wear, extremely wear-proof surfaces, high tensile structural steel materials, stainless steel and special materials increase the high availability of the mixer even further. A broad range of different mixer sizes allow for even more versatility. The smallest model with a drum volume of 5 litres boasts a feed rate of 0.25 m3/h based on retention time and degree of filling. The feed rate of the largest model to date with a 57,000 l drum volume is 1,300 t/h, concludes the company.
