Continuous and forced asphalt mixing production method

A continuous and forced asphalt mixing production method, comprising the following operating steps:

• Step 1, pre-treating a cold aggregate and milled materials;
• Step 2, heating the cold aggregate in a drying cylinder to obtain a hot aggregate, treating the milled materials in a heat transfer manner using hot mixing and/or cold mixing to obtain a recycled material;
• Step 3, weighing and storing the hot aggregate, the recycled material, powder materials and asphalt;
• Step 4, blending the hot aggregate, the recycled material, the powder materials and the asphalt to obtain a premix;
• Step 5, temporarily storing the premix in a pre-stirring storage bin, opening the pre-stirring storage bin to unload the premix when the premix achieves more than 90% of a total capacity of the pre-stirring storage bin, then stirring the premix for 15 to 30 seconds in a forced stirring cylinder, to obtain a finished product material;
• Step 6, temporarily storing the finished product material in a finished product storage bin;
• Step 7, in a finished product material loading area, unloading the finished product material in the finished product storage bin into a storage tank of a finished product material conveying vehicle;
• and
• Step 8, introducing both asphalt flue gas and water vapor generated in Step 4 and Step 5 into the drying cylinder for a secondary incineration;
• discharging dust collected in Step 6 into a tail gas absorption and purification device for a tail gas purification and absorption;
• and introducing a mixed gas of a flue gas and air collected in Step 6 into a burner part of the drying cylinder to be used as a combustion-supporting gas.
