Project overview:
Silicon carbide (SiC) is produced by high-temperature smelting using quartz sand, petroleum coke (or coal coke), and sawdust as raw materials in a resistance furnace. Silicon carbide also exists in nature as a rare mineral, moissanite. Silicon carbide, also known as carbon silica. Among contemporary non oxide high-tech refractory materials such as C, N, and B, silicon carbide is widely used and economical. It can be called diamond sand or refractory sand. At present, the industrial production of silicon carbide in China is divided into two types: black silicon carbide and green silicon carbide, both of which are hexagonal crystals with a specific gravity of 3.20-3.25 and a microhardness of 2840-3320kg/mm2.
Equipment overview:
The silicon carbide drying production line is a new fluidized bed drying equipment developed by our company to overcome the low efficiency and high consumption of static drying. In the design process, the machine fully combines the characteristics of fluidized drying such as air flow drying, maximizes strengths and avoids weaknesses, so that the whole machine has a reasonable process structure and superior performance, achieving the low consumption and goal of fluidized drying.
The machine has a wide range of applications, and can be used for drying fine powder materials with small specific weight such as silicon carbide, black silicon carbide, green silicon carbide, black silicon carbide powder, green silicon carbide powder, foam ceramic silicon carbide, refractory silicon carbide, etc. The equipment has high thermal efficiency, low energy consumption, small footprint, simple configuration, and convenient operation and control.
working principle:
Hot air enters the mixing and crushing drying chamber from the bottom of the dryer at a suitable spraying speed through the air inlet, exerting strong shearing, blowing, and rotating effects on the material. As a result, the material is subjected to centrifugation, shearing, collision, and friction, leading to particle formation and enhanced mass and heat transfer. At the bottom of the dryer, larger and wetter particle clusters are mechanically crushed under the action of the agitator. Particles with lower moisture content and smaller particle size are carried up by the rotating airflow and further dried during the upward process. Due to the rotating flow of gas-solid phase, the inertia of solid phase is greater than that of gas phase, and the relative velocity between solid and gas phases is higher, which enhances the heat transfer effect between the two phases. Therefore, the drying intensity of this machine is high.
Engineering advantages:
1. Strong professionalism, large processing capacity, fast drying rate, greatly increased surface area of the material liquid after atomization, and greatly reduced drying time under vacuum state. 2. The equipment has a simple structure, no vulnerable parts, and low maintenance costs. 3. Simple and stable operation, convenient control, and the ability to achieve intelligent operations. 4. Using different boiling temperatures to achieve liquid-liquid separation. 5. The atomizer adopts a specialized non-standard design, with good atomization and separation effects. 6. Integrating chemical reaction and drying, completing the reaction and drying in one go, optimizing equipment performance.
