The belt scale feeds the materials according to the preset parameters, with a very small error, ensuring the stability and accuracy of the raw material input and laying a foundation for the smooth progress of subsequent processes.
2.Efficient Drying: A paddle dryer is adopted, which skillfully utilizes the low-pressure steam from the thermal power plant and combines it with the supplementary heat from the calcining furnace. This unique drying method efficiently removes the moisture in the raw materials, ensuring that the humidity of the raw materials entering the calcining process meets the standards, and the drying process is energy-saving and efficient.
(II) Core Calcination Process
1.Fluidized Calcination Technology: The dried raw materials enter the desulfurized gypsum calcining furnace, and the fluidized calcination technology is applied to make the materials fully fluidized in the furnace and come into full contact with the heat medium, achieving uniform calcination. This technology can precisely control the calcination conditions, promoting the efficient conversion of calcium sulfate dihydrate into β-hemihydrate gypsum, ensuring the excellent quality of the product.
2.Precise Control of Temperature and Time: Through the advanced automatic control system, the calcination temperature and time are precisely regulated. Ensure that the phase composition of each batch of products is stable and meets the strict requirements of different fields such as construction and industry for the performance of gypsum powder.
(III) Post-treatment Processes
1.Modification and Grinding: The semi-finished product after calcination enters the pin mill for modification and grinding, further refining the particles and improving the surface properties, enhancing the key properties of the gypsum powder such as dispersibility and adhesion in practical applications.
2.Aging and Packaging: The ground product is aged in the finished product silo for 3 days to stabilize the product performance. After that, the automatic packaging machine, with high-precision metering and high-quality packaging, ensures that the product is convenient for storage and transportation, and at the same time, ensures that the product quality is not affected.
