Double Ribbon Mixer

Double Ribbon Mixer

Double Ribbon Mixer

Construction :

Double Ribbon Screw Mixer with full width discharge bottom provide very fast discharge of mixer and are suitable for plants having mixer fitted at some height (i.e., structure) and have surge bin below it. Due to fast discharging, segregation at discharge is greatly avoided.

These mixers consists of U-shaped horizontal through in which a heavy duty shaft with two ribbons in helix shape at different pitch circle diameter are mounted with the help of arms. The ribbon helix is so shaped that when inside mixing shaft rotates, one ribbon pushes the material in one side while at same time other ribbon pushes the material opposite side. So, particles inside the mixer are given very fast movement and homogenous mix is achieved.

Salient Features :Drive system

Suitable combination Inline helical gear box, shaft mounted gear box with V-Belts , or chain sprocket as per suitability to system requirement is used to ensure that it is highly reliable with good factor safety, energy efficient and maintenance free.

Air-Exchange Pipe And Interlocking Doors:

Fitted with air-exchange pipe for smooth filling and discharge of mixer. Accessing doors interlocked with main motor, when opened will not let the mixer to start.

Our patented design

Double ribbon screw mixer is being manufactured in this world from the last many decades with common design features of inner and outer blades. One or more of following problems are generally faced in these designs :-

  • Bending of ribbon and arms particularly near to side walls.
  • Excessive product heating.
  • Longer mixing time.
  • More power per ton of mixing.
  • Mixing not up to the mark.

For achieving same mixing result on any other mixer in its class it will at least save 25-35 percent of time,similarly at least 25-35 percent of power is saved.

In our patented design, both outer and inner ribbons are having variables cross section area that is wider at the start of the ribbon and narrower at the end, both ribbons are having end relief. With these modifications , we have achieved following results:

  • Breakage bending of ribbons completely eliminated.
  • Very less heat is generated.
  • Mixing efficency:Due to the usage of much wider blades,more pitch of blades,higher rpm,the mixing efficency of these mixers is the highest in its class world over.
