Double Shaft Paddle Mixer Machine

Dual paddle mortar mixer is also called non gravity mixer machine or twin paddle mixer, it is widely used for drying and mixing of dry powder mortar, chemical, pesticide, detergent, pigment food, monosodium glutamate, milk powder, salt, feed, chemicals, ceramics, plastics, rubber additives, and other powders.

Working Principle And Structure Editing of Double Shaft Paddle Mixer
To reduce the replacement cost of the wearing parts of the device, the paddle can be made into two pieces, and a movable small blade can be placed on the blade base to directly replace the worn small blade, which is economical and quick; the discharge form is generally a pneumatic (manual) flap valve, and the arc valve is closely embedded. Inside the cylinder, it is flush with the inner wall of the cylinder, and there is no material accumulation and mixed dead angle phenomenon; the standard type has a large opening door and a small opening door, and the large opening door is opened to the side of the cylinder, and the discharging is clean and fast, and the residue is small.

The machine is equipped with a pair of shafts rotating in opposite directions in a w-shaped mixing chamber, and a blade having a certain angle and a certain number of overlapping shapes is mounted on each shaft, and a fluid layer is formed in the mixing chamber having a certain peripheral speed. The materials in the layer are mixed under the action of the convection mixing principle and are in a state of weightlessness in an instant, thus obtaining a homogeneous mixture. A liquid ejecting port may also be provided above the container for solid-liquid mixing of the sprayed liquid.

The machine's turning speed is 50%-80% of the critical speed. When the blade distance is small, the critical speed can be approached.

Structural Characteristics of Double Shaft Paddle Mixer Machine
The double shaft paddle mixer machine makes full use of the principle of convection mixing, that is, the flow layer is formed by the upper throwing motion of the material in the mixer, and the instantaneous weight loss is generated to achieve the optimal mixing effect state. The horizontal cylinder of the machine is equipped with two-axis rotation. Reverse the paddle, the paddle is at an angle to circulate the material in the axial direction and the radial direction, so that the material is quickly mixed evenly.

Application of Dual Paddle Mixer
Dry mortar

Chemicals, chemicals, detergents,

Feed, pesticides,

Pigment food, monosodium glutamate, milk powder, salt

Ceramic, plastic, rubber additives


Main Features of Double Paddle Mixer
1. High efficiency:

Rotate reversely and throw materials to different angles, mixing time only 1-3 minutes

2. High uniformity:

Compact design and rotated shafts be filled with hopper, mixing uniformity up to 99%

3. Low residue:

Only 2-5mm gap between paddles and wall, open -type discharge outlet

4. No leakage:

The patent design ensures the rotating axle discharge outlet wo leakage.

5. Full clean:

Full weld and polishing process for mixing hopper, W/o any fastening piece like screw, nut

6. Elegant appearance:

The whole machine is from full stainless steel to make its profile elegant except gear reducer case, direct mechanism, and bearing seat.
