Intensification of the technological processes by AVS100: powder industry

The main technological advantage of the powder metallurgy industry is usage of the different metals and its alloy combination, metalloids, metal-to-nonmetal joins and others materials like feed stock for the powder material production. Treatment, mixing, dispersing of those components require a lot of time, energy and material costs. In many cases, usage of vortex layer advantages allow simplify the duration of technological processes of powder preparation and its following treatment.

The most typical in this case is the technological processes of high-melting compound production. Those compounds are generally obtained from restoration of transition metal oxide. Formation of the main phase similar to metal occurs by reactive diffusion. This fact imposes stringent requirements to burden material preparation. For example, the size of metals and soot should be fine-dispersed and intimate mixed upon receipt of the carbides (size of the particles should be less than 0.04 mm). All used mills and mixers do not satisfy the requirements of up-dated production. To make the powder with essential granularity apply vibrating sieve sizing by different execution.

Therefore, to obtain the required powders granularity it is using sifting machine with various design vibrosieve. Mixing of burden material compounds spend for a long time to evenly dispense all components. This is necessary operation for obtaining required properties of burden material.

Using of the service capacity with the cooling and without it on the units AVS-100 permit to increase the possibility of the installation.

Besides, Intensifier of Technological Processes can be used also for the mixing of metal powder directly before the sintering.

This list of application of the AVS100 Intensifier of Technological Processes is still incomplete and includes the processes of dispersing, homogenizing, emulsifying etc.

At the table 1 we show the results of our researches where we compared the processes of mixing and dispersion by using the high-profile installation and Intensifier of Technological Processes AVS-100.

Using of AVS-100 in the powder industry will allow intensify the series of technological processes and also upgrade the production, exclude the ball mills and vibrational mills which are the source of the noise and the anthesis.
