Silicone spray drying production line

Material Description:

Si-C alloy is a new type of alloy used in converters, which can replace ferrosilicon, silicon carbide, and carburizer, reduce the amount of deoxidizer, and is used in the deoxidation alloying process of converter smelting. The effect is stable, and the chemical composition, mechanical properties, and internal control quality of the steel grade are superior to traditional processes. Its characteristics include improving the quality of molten steel, enhancing product quality, improving product new energy, reducing alloy addition, lowering steelmaking costs, and increasing economic benefits.

working principle:

This machine is a drying device that uses a high-speed centrifugal atomizer to disperse materials into mist, and completes instant drying by fully contacting with hot air to form powdered finished products. The air first passes through the primary and intermediate filters, is heated by the heater, and then enters the air distributor at the top of the dryer. The hot air enters the drying chamber in a spiral shape and flows in parallel with the hot air. It can be dried into finished products in a very short time. The finished product is continuously output from the bottom of the high-efficiency cyclone separator, and the exhaust gas is discharged by the induced draft fan.

Equipment features:

(1) The drying speed is very fast. After spray, the surface area of the feed liquid increases. In the high-temperature airflow, most of the water can be evaporated instantly. The drying time is generally about 5-40s.

(2) The temperature of the droplets during the drying process is not high, resulting in good product quality. Temperature range for spray drying. Even if high-temperature hot air is used, the exhaust temperature will not be very high. In the early stage of drying, the material temperature will not exceed the wet bulb temperature of the surrounding hot air, which is particularly suitable for heat sensitive materials.

(3) The product has good dispersibility, fluidity, and solubility. Due to the fact that the drying process is carried out in air, the product naturally maintains a spherical shape similar to droplets and has good fluidity.

(4) The production process is simplified and the operation control is convenient. Spray is usually used to treat solutions with moisture content of 40% -90%, which can be dried into powder products at one time. Most products do not need to be crushed and screened after drying, thus reducing the production process and simplifying the production process. The particle size, bulk density, and moisture content of the product can be adjusted by changing the operating conditions within a certain range, which is relatively easy to control.
