General machine description

Turbo Screener is a continuous classifying machine having a horizontal
cylindrical screen with a range of opening size from 10 to 1000 μm in which
the raw material is conveyed from inlet to outlet by means of blades rotating
at a high speed.

Separation Principle
The raw material fed from machine inlet is conveyed into the entrance ofcylindrical screen through the screw and is dispersed evenly over the innersurface of screen by blades rotating at a high speed. As these blades have atorsion angle, the raw material is moved from the entrance of cylindricalscreen entrance to its exit spirally turning on the inner surface of screen.
During the conveying the accelerated raw material by blades rotating at ahigh speed hits the inner screen surface, which causes very fine vibration ofscreen both at front and rear sides of blades. This vibration has a highfrequency and a large acceleration force, by which the finer particles thanscreen opening size pass though it and is collected through the outlet forfine, while coarser particle than screen opening is carried to its exit and overflow from there and collected through the outlet for coarse. Such process isdone simultaneously preventing screen from clogging.

CHARATCTERISTICS＊The raw material fed into the machine isdispersed by blades rotating at a highspeed, which creates a high frequency
vibration. This vibration prevents thescreen from clogging.
＊Even an agglomerated raw material canbe disintegrated by the rotating blades
and is dispersed homogeneously overthe screen inner surface, which results
in a high separation accuracy.
＊ The number of blades, their torsion
angle and rotation speed will bedecided according to the purpose of
the separation. Therefore, even veryfragile granules can be separated
without being destroyed by adjusting
the machine to a short retention timeand a soft agitation.
＊The change of screen can be done in a
few minutes by having a spare screen
frame.（Photo１）＊The cylindrical screen can be taken out
only by opening the front door. Therotor, and the screw part can also be
dismantled each separately and veryeasily without using any tools for athorough cleaning of each machinepart. For the small to medium machinetypes are conformed with GMP andtherefore, very suitable for theapplication of pharmaceutical, food,fine chemical uses

＊ By applying anti-abrasion
materials to the machine andspecially designed protection
to the cylindrical screen highlyabrasive raw materials such as
metal
powder,corrosive
powder can betreated keeping a longmachine life time.

＊ Using special geometry
blades and urethane madetapping balls sticky raw
materialduetostatic
electricity like powder paintand toner can be separated.
To prevent the accidental
escape of ball into theproduct a specially designedballescapeprevention
device is also available as anoption.
＊ An optional air flow device(Pat.) is also available to gain
an outstanding product yieldfor
very
difficultrawmaterials to be separated.
＊ Vibration and noise free
operation is possible.

machine (Roller Compactor) for the elimination of fine powder part.
＊ Separation into 3 product size ranges------Type,TS250x400-IIBS is available for the separate 3 product sizes by one
machine.…
This type is very advantageous in case of shortage of the installation
space for 2 Turbo Screeners.
