Ultrasonic Vibrating Screen for Fly Ash

The appearance of fly ash is similar to cement, and the color varies from milky white to gray-black. The color of fly ash is an important quality indicator, which can reflect the amount and difference of carbon content. To a certain extent, it can also reflect the fineness of fly ash. The darker the color, the finer the fly ash particle size and the higher the carbon content. Fly ash is divided into low calcium fly ash and high calcium fly ash. Usually the color of high calcium fly ash is yellowish, and the color of low calcium fly ash is more gray. The fly ash particles have a porous honeycomb structure with a large specific surface area and high adsorption activity. The particle size of the particles ranges from 0.5 to 300 μm. And the bead wall has a porous structure, the porosity is as high as 50%-80%, and it has strong water absorption. The screening and impurity removal of fly ash usually use an ultrasonic vibrating screen, and the mesh is generally 400 mesh. The following is a detailed introduction to the ultrasonic vibrating screen for fly ash.

The ultrasonic vibrating screen organically combines the ultrasonic controller and the vibrating screen. On the basis of the DH series rotary vibrating screen produced by Dahan Machinery for many years, a high-frequency and low-amplitude ultrasonic vibration wave is superimposed on the screen. The body accepts huge ultrasonic acceleration, so that the material on the screen surface is always in a suspended state, thereby inhibiting the blocking factors such as adhesion, friction, leveling, wedging, etc., thus solving the problem of strong adsorption, easy agglomeration, high static electricity, and high precision. , high density, light specific gravity and other screening problems, so that the screening of ultra-fine powder is no longer a difficult task, especially suitable for users of high-quality, fine powder.

1. High screening output

Ultrasonic vibrating screen can be used in single layer and multi-layer, and the output is 2-10 times that of ordinary vibrating screen.

2. High screening efficiency

Ultrasonic vibrating screen is a set of ultrasonic device added on the basis of rotary vibrating screen, so that the insulating powder on the screen surface is kept in a suspended state, which effectively solves the problem of strong adsorption, easy agglomeration, high static electricity, high precision and light specific gravity of insulating powder. Sifting problems.

3. High screening accuracy

Dahan ultrasonic vibrating screen is larger than 500 mesh can be effectively screened, with self-cleaning function, no need to add a cleaning device, the mesh is not blocked.
