Screening Titanium & Alloy Powders

Making the grade in the medical market

Whereas powders in the range of 150μm/100 mesh are suitable for many industries, the medical field requires even finer material. To satisfy this need, Reading Alloys sought to ramp up its capacity to produce titanium and alloy powders from 300μm/50 mesh to 45μm/325 mesh. However, the company noticed its existing vibratory screeners were experiencing problems attaining the necessary particle size distributions, throughput, and material recoverability.

Ultrasonic sieving of titanium and alloy powders

In search for a new solution, Reading Alloys turned to the Russell Vibrasonic® system. The system uses a combination of ultrasonics and conventional vibration and can be retrofitted onto any new or existing vibrating separator/screener. By using an acoustically developed transducer, an ultrasonic frequency is applied directly to the screener mesh to break down surface tension, effectively rendering the stainless steel wires friction free. This eliminates mesh blinding and enables accurate separation down to 20μm on even difficult powders, while maintaining product consistency. As the machine does not have to be stopped for operators to manually clean and handle the mesh, downtime is also reduced and screen life is prolonged.

What our clients say

“The Vibrasonic system has helped eliminate blinding at the fine mesh sizes/narrow particle size distributions required by the medical market, all the way to 45μm/325 mesh. It has enhanced our material throughput to the point where we can meet specified requirements in virtually a single screening pass, while improving material recoverability.”
