Turbo Mill model S & M
GRINDING PRINCIPLE
A fine grinding machine by means of vortex airstreams. Grinding is done by mechanical impact of rotating blades as well as intensive vortex airstreams and high frequency of air pressure oscillation generated at the backside of rotating rotor blades. This mill can grind heat-sensitive materials without damage as grinding takes place in the airstreams that can take heat away.
❖ MACHINE STRUCTURE
Material is taken into the mill being carried by airstream. The airstream containing material is given spiral motion in the inlet spiral chamber⑨ and transmitted evenly into the grinding chamber. Grinding takes place between rotor blades④ and liners⑦ by mechanical impact, intensive vortex airstreams and high frequency of air pressure oscillation, and after that the ground product is taken out through outlet of vortex chamber⑩ carried by airstream.
CHARACTERISTICS
- Sharp product particle size distribution 【Product side range: d50=20 to 500 micron meter】
Product contains very few percentage of excessively fine part and its particle size distribution curve is very sharp.
❖ APPLICATION EXAMPLE
・ABS resin [Particle size before grinding: d50=348 micron meter]
⇒ After grinding (* Special specifications) 【Product size: d50=28.69 micron meter】
- Efficient removal of grinding heat
Airstream takes the heat generated by grinding from the product. - Robust machine construction
As it has no screen inside and the structure is very simple that makes long time running possible without trouble. - Low costs peripheral equipment
Since Turbo Mill itself generates airstream, required system air volume is relatively small and the investment costs on peripheral equipment like suction blower is accordingly low. - Wide range of application
Chemicals, foods, pharmaceuticals, etc. - Various derivative machine types To meet various requirements we have a number of derivative types like type S (Standard), type M,type E and type R to obtain from coarse to fine products.
Machine type Type S (Standard) Type M Number of rotors 4 8 Number of blades 14×4 28×8 Gap size between rotor and liner(mm) 3~10 Anti-abrasion specifications hardening/tempering of stellite pudding / WC chip brazing BLADE & LINER SHAPES
