Double Shaft Paddle Mixer2

Working Principle

1. Double shaft paddle mixer is with 2 horizontal paddle shaft; there is the paddle on each shaft;

2. With the driven equipment, two cross paddle shafts moves intersection and patho-occlusion.

3. Driven equipment makes paddle rotating fast; the rotating paddle generates centrifugal force during high speed rotation, spilling the material to the upper part in the barrel, then material falling down (the vertex of material is in a so-called instant non-gravity state). Driven by the blades, material is mixed back and forth; also sheared and separated by the meshing space between the twin shafts; fast and evenly mixed.

A: Flexible material selection

Material can be carbon steel, manganese steel, ss304, 316L and Carbon steel; besides, different Material can also be used in combination. Surface treatment for stainless steel include sandblasting, wiredrawing, polishing, mirror polishing, all can be used in different parts of a mixer.

B: Various Inlets

Double Shaft Paddle Mixer11

Various inlets on the top cover of the barrel can be designed according to different situations. They can be used as man hole, cleaning door, feeding hole, vent, and dust colleting hole. The top cover can be designed as fully-opened lid for easy cleaning.

C: Excellent discharging unit

Double Shaft Paddle Mixer12

The drive types of valve are Manual, pneumatic, and electric.

Valves for consideration: powder spherical valve, cylinder valve, plum-blossom dislocation valve, butterfly valve, rotary valve etc.

D:Selectable Function

Double Shaft Paddle Mixer13

Paddle blender sometimes needs to be equipped additional functions because of customer requirements, like jacket system for heating and cooling, weighing system, dust removal system, spray system and so on.

E: Adjustable speed

Powder ribbon blender machine can be customized into speed adjustable by installing a frequency converter. And for motor and reducer,it can change the motor brand, customize the speed, increase the power, add the motor cover.

6.What products can ribbon blender mixer handle?

It is used for mixing powders, powder with liquid and powder with granule and even the smallest quantity of ingredient can be blended efficiently with large volumes. Ribbon mixing machines are also useful for agricultural chemicals, food, pharmaceuticals, etc. Ribbon mixing machine offers highly uniformity mixing for efficient process and result.

7. How do industry ribbon blenders work?

Double layer ribbons which stand and turn in opposite angels to form a convection in different materials so that it can reach a high mixing efficiency. Our special design ribbons can achieve no dead angle in mixing tank.

The effective mixing time is only 5-10 minutes, even less within 3 min.

8.How to select a double ribbon blender?

Choose a suitable model 

Ribbon blenders have the effective mixing volume. Normally it is about 70%. However, some suppliers name their models as total mixing volume, while some like us name our ribbon blender models as effective mixing volume. You need to calculate the suitable volume according to your product density and batch weight. For example, manufacturer TP produces 500kg flour each batch, whose density is 0.5kg/L. The output will be 1000L each batch. What TP needs is a 1000L capacity ribbon blender. And TDPM 1000 model is suitable. 

Ribbon blender quality  

Shaft sealing: 

test with water shows the shaft sealing effect. Powder leakage from shaft sealing always troubles users. 

Discharge sealing: 

test with water also shows the discharge sealing effect. Many users have met leakage from discharge. 


Full welding is one of the most important part for food and pharmaceutical machines. Powder is easy to hide in gap, which may pollute fresh powder if residual powder goes bad. But full-welding and polish can make no gap between hardware connection, which can show machine quality and usage experience. 

Easy-cleaning design: 

A easy-cleaning ribbon blender will save much time and energy for you which is equal to cost.
