Ultrasonically assisted powders production


High intensity and high capacity ultrasonic atomizers are applicable to the atomization of all kinds of organic and inorganic liquids, and powders production, in the chemical industry, metallurgy, food-industry, pharmaceutics and cosmetics.


Applicable for cold or hot atomizing and pulverizing of: different liquid solutions, liquid metals, salts, minerals, chemicals, paraffin, chocolate mass, polymers, liquid-sugar, painting and coating products, and all other unspecified low and high viscosity (and variable density) liquids. Atomization can be made: on atmospheric, reduced or elevated pressure, on room, or any other temperature, in an inert gas environment, in a direct contact between ultrasonic atomizer and liquid to be atomized, or remotely (transferring ultrasonic pressure-waves through gas media, without touching a liquid) etc.


Using very specialized ultrasonic atomizing systems, a very high flow rate of almost any liquid can be easily transformed into fine spray and dried (dehydrated) in line, eliminating drying, solidifying or cooling channels and creating very fine dry powder as the end-product.


Very often, in various chemical and metallurgical processes, it is technologically extremely beneficial to use fine powders of certain salts, oxides, metals, chemicals or other raw materials, which are usually found as granulates in macro crystalline forms. In order to transform these macro crystalline materials into fine powders it would be necessary to mix, melt, homogenize and transform them ultrasonically (or by some other means) in a convenient liquid form, and then to atomize such liquid. The most convenient and efficient method is to use an ultrasonic atomizer, producing a very fine spray, and dry (cool / solidify) the spray in-line, as it free falls. This will result in very fine powders.


The difference between the technology proposed here and currently known Ultrasonic Atomizers is that this technology has no temperature limits, and any flow rate can be realized by relatively simple scaling means (not possible using other currently-available ultrasonic atomizers).
