The kiln dryer is a kind of large-scale drying equipment in the industrial production and it is widely used in the production of the cement industry, metallurgical industry, wood drying and the brick drying. The reaction temperature of the kiln body is relatively high in the production process of the kiln dryer. Therefore, the temperature of the kiln body and the collection and monitoring of other process parameters are the very important aspects to ensure the roasting quality.
For the kiln dryer produced by Henan Hongxing Mining Machinery Co.,, the shell is made of the welded steel and imported color steel tile. The inner wall is made of the high-strength anti-corrosion aluminum plate. The inside plate and outside plate are filled with the new insulation materials. The kiln is composed by the evaporator, blower, furnace, scattered wind pipe, moisture removal device and the control box, etc.. The hot air steam into the kiln dryer is totally separated from the combustion chamber. Therefore, the materials dried will not be deformed. The kiln dryer produced by Henan Hongxing Mining Machinery is composed by two parts, namely the combustion device and the drying kiln. The working principle of the hot air drying apparatus is to use the heat energy produced by the conbusition to heat the air in the kiln. The host at the top of the hot air furnace can be used to suck the air in the kiln into the body of the furnace and heat the air. Then the pipe can be used to send the hot air to the kiln. The circulating fan continuously circulates to evenly heat the materials in the kiln. The vapour needed in the drying process for the materials can be supplied by the steam generator in the hot air furnace. There is insert valve equipped in the pipe. The insert valve can be adjusted to control the temperature of the kiln. The kiln dryer produced by Henan Hongxing Mining Machinery is equipped with the heat recovery unit which can take full advantage of the drying medium to greatly reduce the drying costs and improve the economic efficiency of enterprises.
