Turbo Mill model E, R & CR

❖NEW PRODUCT❖　『Multi-cooling System TURBO MILL』

GRINDING PRINCIPLE

A ultra-fine grinding machine by means of vortex airstream. Ultra-fine 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 and the groove slopes.

This mill can grind heat-sensitive materials without damage as grinding takes place in the airstream that can take heat away.

❖ MACHINE STRUCTURE & MATERIAL FLOW

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 airstream and high frequency of air pressure oscillation, and after that the ground product is taken out through outlet vortex chamber⑩ carried by airstream.

CHARACTERISTICS

1. Sharp product particle size distribution 【Product side range: d50= 3 to 50 micron meter】
   Product contains very few percentage of excessively fine part and its particle size distribution curve is very sharp.
   
   
   
   ❖ Application example by Model T400 RS

   ---

   ・Battery material(Carbon)【Particle size before grinding: d50=ca.600 micron meter】
   　
   ⇒ After grinding (by 1 pass)【Product size: d50=3.46 micron meter】
   　
   
   
2. Efficient removal of grinding heat
   Airstream takes the heat generated by grinding from the product and thus heat-sensitive materials like toner can be well ground.
   
   
3. Low running costs
   Much lower running costs in comparison with those by a jet mill.
   
   
4. Continuous long running possible
   Design for long time continuous trouble free operation without heavy maintenance.
   
   
5. Easy machine cleaning
   Mill casing is designed consisting of 2 parts which are fixed together at an angle of 45 degree and is possible to open the upper one so as to enable to clean inside the chamber with ease.
   
   
6. 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.)

• アンバランスを発生させない構造設計
• 高速対応のロータリージョイント

CHARACTERISTICS

1. Specially designed coolant channel to achieve effective heat removal.
2. Doubled throughput compared with conventional type without cooled rotor.
3. Even smaller product particle size can be obtained.
4. In case of new machine installation considerable costs down is possible with smaller cooling utilities.
5. Capable of grinding of heat-sensitive materials like toner and powder coating
6. Cooled rotor can be retrofitted on a existing mill with non-cooled rotor.

Comparison graph of heat removal between the mills with cooled and uncooled rotors (by model T400-CRS).

• 『ローター冷却』+『ジャケット冷却』+『プラス冷風』の3倍冷却方式にて
  当社比2.5倍以上の冷却効果！

• Cost cutting is possible by replacing a big capacity air-cooler to cool down air under 0 degree C with smaller one, as the heat removal efficiency of 1.3 times higher with this system in our internal tests result by both jacket cooling, rotor cooling and air cooling sat over 0 degree C.
