Unitfine Ribbon Mixer


Ribbon mixer is widely used in chemicals,pharmarcy,food, and construction materials industry etc, which could be used for mixing of powders, powders and liquid, powders and granules etc.


Inside the mixer there are ribbons in convective direction,inner and outer, up and down to even powder in short time.Air leakproof device” is patent design to prevent powder pollution. According to particular powder, Heating system, Liquid Spraying system and High speed chopper can be installed in mixer to solve the special mixing requirement.


  • Mixing blade is two spiral “S” type design.
  • Excellent and high speed mixing efficiency.
  • Powder won’t be raised mixing operation.
  • Complete and through of raw materials by ribbon agitator which create two layers and counter movement of flows.

  • Material: Steel thickness of outer shell, blade and cover is two times of others. The durability is over 20 years.
  • Speed: Double spiral ribbon blade makes higher mixing speed than others.
  • Bearing: Teflon seal can avoid powder leak. Split assembly can separate power from machine grease.
  • Convenient: Single side assemble makes maintenance easier.
  • Output: Power discharge via “butterfly valve”. Rigid seal will avoid powder leak. Liquid mixing & washing are applicable.
  • Independent control panel: Let cleaning safety.

Model Selecting:

Generally ribbon mixer model is selected according to batch capacity.

  • Batch capacity: 0.1-20 Cubic meter per batch.

How to select a ribbon mixer?

1.Please tell the volume of batch products, range 0.1 to 20 cbm.

2.Select material of the mixer, contacting products parts,and other parts , so please tell your own products working condition,sanitary requirements.

3.Please tell specific gravity and flowability of your products, with which we would select a right motor for you.

4.Please tell f you need any other auxiliary equipment, such as cool and warm keeping, spay etc.

5.Please tell openings requirement of the mixer, such as feed inlet,cleaning windows, exhaust hole etc.
