Crystal dehydration and washing without fracture
Pusher™ is a centrifugal filter consisting of two cylindrical baskets with metal screen that are horizontally installed on a driving shaft. Slurry with crystals or pellets is fed on the inner basket, and the solids are kept on the screens and move towards the end of the outer basket by oscillation of the inner basket. They are dehydrated to a low moisture content and discharged from the outer basket. It is possible to minimize damages on the solids, since the first basket oscillating with short stroke gradually pushes bulk of the solids, not individually. Thus, this model is ideal for treatment of crystals and pellets to avoid damages to fragile particles. In addition, even when processing hard crystals, wear of the screens and conveying parts are lower than other filters, resulting in longer maintenance periods and stable processing.
This model is also available for washing solid form impurities by showering clean water or rinsing solution during the solids moving on the basket screens, and it has a function of dewatering and washing solids at the same time. This is an ideal device for dehydration and washing of resin and nylon pellets of 0.1mm or larger, ammonium sulfate, salt, etc.
This machine consists of a large (outer) and a small (inner) basket, and wedge wire screens are installed inside the baskets. A slurry is fed to the accelerating hopper via the supply pipe and is carried to the inner basket. Then the particles in the slurry are scattered on the screen and are instantly dehydrated. The particles overflow from the inner basket and drop on the outer basket. The inner basket oscillates back and forth in the axial direction. This motion helps particles’ move of the overflowing from the inner basket and pushes the particles on the outer basket towards the basket end. During the particles move on the screens, they are dewatered rapidly. In addition, impurities on the particles are washed out by spraying a rinsing solution to the screens.
