Assonic has supported companies in the chemical industry in the screening of chemical powders for 10 years. 

Our know-how and leadership in technology have made us an established supplier to this complex industry.

Our products and services are used in various steps of the process: separation of oversized grains, precise separation and safe preparation of various powders such as calcium carbonate or titanium dioxide.

Our patented SONIC SPEED SCREEN™ technology ensures high throughputs as well as free screen linings by simultaneously stimulating it at high and low frequency.

The high-frequency ultrasound, ranging from 30 to 38 kHz, ensures the reduction of adhesion and frictional resistance.


The low-frequency pneumatic stimulation, ranging from 100 to 250 Hz, ensures additional mixing of the powder.
