Project Overview:
Silicon carbide (SiC) is made of quartz sand, petroleum coke (or coal coke), and wood chips as raw materials through high-temperature smelting. Silicon carbide also exists in nature as a rare mineral, moissanite. Silicon Carbide is also called Carborite. Among contemporary non-oxide high-tech refractory materials such as C, N, B, silicon carbide is the most widely used and economical one. It can be called golden sand or refractory sand. At present, China's industrial production of silicon carbide is divided into black silicon carbide and green silicon carbide, both of which are hexagonal crystals, with a specific gravity of 3.20 to 3.25, and a microhardness of 2840 to 3320 kg / mm2.

Equipment overview:

Silicon carbide drying production line is a new and efficient fluidized drying equipment developed by our company in order to overcome the low efficiency and high consumption of static drying. In the design process, the machine fully combines the characteristics of flow drying such as air drying, so as to avoid strengths and weaknesses, so that the machine has a reasonable process structure and superior performance, and truly achieves the goal of low consumption and high efficiency of fluidized drying.
This machine has a very wide range of applications. It can be used to dry fine powder materials such as silicon carbide, black silicon carbide, green carbon silicon, black carbon silicon powder, green silicon carbide powder, foam ceramic silicon carbide, and refractory silicon carbide. The equipment has high thermal efficiency, low energy consumption, small footprint, simple configuration, and convenient operation and control.

working principle:

The hot air enters the stirring, crushing and drying chamber from the bottom of the dryer through the air inlet at a suitable spraying speed. The material is strongly sheared, blown, and rotated. Therefore, the material is micronized by centrifugation, shearing, collision, and friction. Enhanced mass and heat transfer. At the bottom of the dryer, large and wet particles are mechanically broken under the action of the agitator, and particles with lower moisture content and smaller granularity are entrained by the rotating airflow and further dried during the rise. For rotating flow, the inertia of the solid phase is greater than that of the gas phase. The relative speed between the two phases of the solid and gas is relatively large, and the heat transfer effect between the two phases is enhanced, so the machine has high drying strength.

Engineering advantages:

1. Strong professionalism, large processing capacity, fast drying rate, the surface area of the material liquid after atomization is greatly increased, and the drying time is greatly reduced under the vacuum state. 2. Simple equipment structure, no wearing parts, low maintenance cost. 3. Simple and stable operation, convenient control and intelligent operation. 4. Use different boiling temperature to realize liquid-liquid separation. 5, using a special non-standard design atomizer, atomization, separation effect is good. 6. It integrates chemical reaction, drying and integration, and completes reaction and drying at one time to optimize equipment performance.
