Double Shaft Paddle Mixer is a device used to mix powdered, granular, flake, block and thin materials. It is a device that uses a pair of spiral shafts with stirring blades to synchronously rotate, spray, humidify and stir the powdered materials while conveying them. It can be used to mix and crush clay materials in the ceramsite industry; powder and other raw materials and aggregates, additives, etc. are evenly mixed and mixed.
The working principle of a double shaft paddle mixer is based on the principle of convection mixing. It uses the upward motion of the material in the mixer to form a fluidized layer, produce instantaneous weightlessness, and achieve the best mixing state. The rotation speed of the equipment is usually 50%-80% of the critical speed. The paddle moves the material from A to B at a specific angle, and then achieves all-round mixing through axial movement.
During the working process, the transmission device drives the two blade shafts with stirring blades to rotate synchronously. When the material enters the machine slot from the feeding port, the water spraying device immediately sprays water to change the material from dry to wet; while humidifying, the wet material is continuously stirred and mixed with each other under the action of the spiral stirring blades, and moves toward the discharge port, and finally the qualified material is unloaded from the discharge port.
It is suitable for stirring viscous materials such as sludge, oil sludge, coal slime, bentonite, etc. The materials are very viscous and difficult to stir.
