Plasterboard Equipment

The Plasterboard equipment drying process of Shandong Tengfei Electromechanical Technology Co., Ltd. adopts the most advanced hot air drying process in China

Plasterboard equipment drying Principle: the high-temperature hot flue gas produced by coal combustion is returned into clean hot air through the heat exchanger, and is driven by the induced draft fan to circulate in the dryer to dry gypsum board.

Each layer of the dryer is equipped with multiple hot air nozzles, which can freely adjust the air volume of each layer of the dryer. The temperature adjustment of each layer of the dryer is easier and more uniform, the temperature difference of each layer is smaller, and the temperature difference between layers is between 2-4 degrees.

Product Details

Each nozzle is equipped with multiple air outlets, which can freely adjust different wind directions of each nozzle, so that the moisture content error of the same gypsum board in different parts does not exceed 1%

Forced dehumidification by fan is conducive to the drying of gypsum board.

When adjusting the temperature of the dryer, the cooling and heating adjustment reaction is rapid.

The hot blast stove automatically adjusts the coal feeding amount according to the flue gas temperature, with high thermal efficiency. At the same time, the thickness of the insulation door and the upper bottom cover plate is 160mm (with thermal insulation rock wool inside), which has good thermal insulation effect, improves the drying efficiency of gypsum board, and saves energy obviously. Generally, the energy saving is more than 30%.

The tail gas recovery system and dryer hot air curtain system are added, and the temperature of exhaust gas is controlled to about 100 degrees to further save heat energy.

DCS control system, hot blast stove, dryer and tail gas replenishment system are adopted to form closed-loop control, automatically adjust various indicators, improve the degree of automation and make the production process control more stable.
