Non - Supported Screw Model
|
|
| |
|
|
| |
-
An important engineering development
with the MIKRONS Nauta mixer is the non-supported
screw design in sizes upto 1000 litres volume.
-
In this case, bottom support is
not required for the screw. As a result, the lower
portion of the cone is of modular construction.
-
These opening may be used for
a discharge valve, cleanout port, lump breaker,
porous diffuser plates for air drying, spray attachment,
etc.
-
An additional benefit of the MIKRONS
mixer with non-supported screw is that materials
can be discharged directly from the bottom of the
cone; rather than through the side, this will not
only speed up product discharge, but will also greatly
enhance discharge of difficult-to-move materials.

MIKRONS Mixer series may also be equipped
with a bottom-supported screw for higher capacity model
involving heavy materials or specialized applications.
The screw may be supported by a pintle bearing. |

Twin Screw model |
|
| |
The twin screw mixer is suitable for
mixing and blending a wide range of materials both in
powder and paste forms. To the triple action of the single
screw a fourth is added intermixing between two screws.
Mixing time is up to 90% faster |

Vacuum operation |
|
| |
Vacuum mixers are available in case
of applications that are designed specifically for mixing
heavy paste products. Mechanical seals are provided for
these mixers. |

Dryer |
|
| |
|
|
| |
Generally nauta mixers are used for
drying purpose, Those mixers which are used for drying
are provided with MS jacket and limpet coil. |

The blender used in pharmaceutical
industry comes with ribbon shaped agitator as against
the screw design. The agitator is mounted vertically and
rotates at close clearance to the conical vessel walls.
Materials being mixed are moved in axial and radial directions
by the agitator. The outer helix moves materials from
the walls up and the screw moves materials from the bottom
to the top of the vessel. The cone design helps to insure
a complete discharge of all materials. |

The small capacity mixers are designed
to serve as a lab mixer and for use in small production
runs. It has a maximum capacity of 50 litres. |
