Mixing principle
Overlapping Paddle Action in a W-Shaped Trough
Two counter-rotating shafts use overlapping paddle blades to divide, fold and recombine material. The design is intended for demanding, high-viscosity materials where complete discharge and intensive working action matter.
100–10k LDPM total volume range
3–110 kWListed motor power range
10–80 RPMListed speed range
2 shaftsCounter-rotating paddles

Counter-rotating paddles divide material throughout the trough.
Overlap zone
The paddle overlap zone folds and recombines viscous material.
Liquid dosing
Spray-bar systems can introduce liquid or binder during mixing.
Dual discharge
Bottom discharge paths support complete emptying of sticky batches.

Frequently asked questions
Double Paddle Mixer Questions
What makes a double paddle mixer different from a ribbon mixer?
The twin counter-rotating paddle design creates an intensive overlap zone and is described for pastes, doughs, slurries and high-viscosity materials. Ribbon mixers are commonly selected for free-flowing dry powders.
Can it handle wet or paste materials?
Yes. The existing DPM application range includes pastes, doughs, slurries and wet granulation masses, with liquid addition available via spray bar.
What model range is available?
The listed DPM series ranges from 100L to 10,000L, with DPM-200, 800, 1500 and 3000 also available.
Can vacuum operation be added?
Vacuum operation is an available option for deaeration during mixing when air entrapment is a process concern.
Are heating and cooling available?
Heating or cooling jacket configurations are available for temperature-sensitive or reactive materials.
How should I size the mixer?
Send your batch volume, viscosity, bulk density, liquid addition, temperature and discharge requirements for a suitable configuration.

Introduction
Double shafts paddle mixer is high-performance mixer for powder, granules, liquid additives, short fibres, etc. like for mixing moistening, agglomerating, and granulating material, which is widely used in food, feed, chemical, dry mortar industries etc.
With the most powerful motor and double shaft paddle structure, material can be mixed evenly in the shortest time. It is particularly good at mixing material with big difference in gravity, mesh size, fluidity. Four or two hatches on the side of the machine (depending on the size of the mixer) ensure easy and hygienic cleaning of the system.
where requried, spray lines, side clean doors, high-speed choppers, heat or cold jacket，different functional coating can be installed to achieve the desired mixing effect.

Details
Mixing Unit
paddle mixer is a high-precision blending machine that can achieve excellent mixing results even when the materials have significant differences in density, particle size, and proportions. This is due to the rapid and intense tumbling and scattering of the materials by the interlaced paddle blades.
Gearbox
For large-scale mixers with a capacity of over 6 cubic meters, an inline gearbox is used to increase torque and reduce maintenance rates, effectively addressing some of the previous drawbacks.
Two-piece blades
To reduce the cost of replacing vulnerable parts, the paddle blades can be made in a two-piece design. A movable small blade is placed on the blade base, allowing for direct replacement of worn-out small blades. This approach is economical and efficient.
Discharge valve
Standard valve for double shaft paddle mixer is twin pneumatic planar flap valves. When close the valve, the planar flaps match the mixing barrel perfectly, this makes no mixing dead zone and better mixing effect.
