Ultrasonic Vibrating Screen for Silicon Powder

We have a customer which is a silicon powder manufacture. Before they used a simple  vibrating screen which is made by themself . The processing capacity is low and the screening effect is poor. And they use 200 meshes but many fine sizes are difficult to sieving. At the same time, the customer wants to improve the product quality through a 300 mesh screen.

In order to give customer better advice, we recommend the customer sent us 20kg sample materials and use our vibrating screen machine.

First we use a 200-mesh rotary sieve to sieving. we found that the material sieving works much better than their site vibrating screen.

then we replaced with 300 mesh, and the material could still be sieved, but the efficiency was greatly reduced. according to our experience, we replaced the equipment with an ultrasonic vibrating screen, and opened the ultrasonic system during screening. Through observation, we found that the fine size which were originally difficult to pass were quickly sieved by the high-frequency vibration force of the ultrasonic system.
