Double drum dryer refers to the dryer by two rollers at the same time to complete the drying operation of the machinery, dryer two rollers by the same set of deceleration transmission, by the same modulus and number of teeth of a pair of gears meshing, so that the two groups of the same diameter of the drum relative rotation and operation.
Double drum dryer According to the cloth position is different, can be divided into two types of rolling and coaxial type. To the rolling double drum dryer, the material liquid exists in the middle Groove area of the two rollers, surrounded by weir plate retaining material. The gap between the two cylinders, controlled by a pair of circular diameters consistent with or similar to the outer diameter of the cylinder, is generally in the 0.5~LMM range and does not allow the material liquid to leak. The direction of rotation of the roll can be determined according to the actual material and the requirements of the device layout. When the bite angle of the drum rotates at the end of the material, the thickness of the material film is controlled by the gap between the two cylinders. If the bite angle is in reverse, the thickness of the material film between the two cylinders is controlled by the gap between the weir plate and the cylinder arranged in the direction of the length of the cylinder. This form of dryer is suitable for drying slurry materials with precipitation or large viscosity materials.
