In order to increase the material evenly distributed in the drum section parts on good contact with the drying medium, in the rotary dryer cylinder body device Yang board. Yang board types are the following:
A lifting-type Yang Board: For bulk materials or easily bonded to the tube wall material.
Second, the four formats Yang board: for density, not brittle or easily dispersed materials. The cylinder is divided into four panels will Yang grid, showing each other through the fan operating room, materials and hot gas contact surface than the Yang-style plate lifting large, and the filling material can increase the rate and reduce the height of material fall and reduce the amount of dust losses and so on.
Third, the cross or frame-shaped Young Board: For a more brittle material and easily dispersed into small pieces, so that material can be evenly dispersed throughout the tube cross-section.
Fourth, the sleeve-type Yang board: for the duplex heat (or semi-diameter heat) rotary drum dryer Yang board.
Five sub-format (fan) board for Jan easily understood cause very fine particles flying powder materials. Material deposited on a grid to enter on board, when the cylinder rotation, the material is constantly turning and contacts with the hot gas, while the reduced height of land because of the material, reducing the drying material is the possibility of gas away.
All of the above forms of Yang board can be distributed throughout the cylinder body, to make the material more quickly and evenly to the Yang-board, can also feed at the end of 1 ~ 5m spiral-shaped guide plate installed to prevent the wet material accumulation in the cylinder wall bonding. At the same time because of dry material can easily be raised and taken away by exhaust gas, while in the discharge at the end of 1 ~ 2m Renhe Yang board is not installed.
