Individual revolution and rotation speed control system

Equipped with revolution and rotation individual speed control system.
The ratio of revolution and rotation can be adjusted; thus 90 different speed combinations can be set.

All-in-one support of other applications (abrasive, coating, etc.).
With ordinary models, the rotation speed ratio is fixed by the gear ratio, so even if the speed of revolution is adjusted, some materials may not properly mix or create lump, and practically these problems could not be solved.
By contrast, with the individual speed control system, revolution can be set in 9 steps, rotation in 10 steps, providing the advantages below.

6 advantages of variable rotation speed

Furthermore, this keeps the temperature of the material down!

Rather than simple adjusting the speed of revolution, the speeds of revolution and rotation are optimized, thereby sustaining the thermal elevation of the material.

Revolving speed setting table

To keep rotation direction is as usual, new function which revolving direction is changeable either clockwise or anti-clockwise for revolution. Under vacuum pressure, it may change material property, however it enables to achieve high precision degassing even atmospheric pressure condition.

To keep centrifugal force of revolution, it enables to achieve setting which revolving speed pf rotation can be surpassed to revolving speed of revolution. Mixing force is drastically enhanced, thus it can correspond to various materials case.
