Project Overview:
Silicon carbide (SiC) is produced by high-temperature smelting using quartz sand, petroleum coke (or coal coke), and sawdust as raw materials. Silicon carbide also has a rare mineral, Moissanite, in nature. Silicon carbide is also called carbon silica. In contemporary non-oxide refractory materials such as C, N, and B, silicon carbide is widely used and economical. It can be called grit or refractory sand. At present, China's industrial production of silicon carbide is divided into two types of black silicon carbide and green silicon carbide, are all hexagonal crystals, the specific gravity of 3.20 ~ 3.25, the microhardness of 2840 ~ 3320kg/mm2.


Equipment Overview:
Silicon carbide drying production line is a new type of efficient fluidized drying equipment developed by our company to overcome static drying inefficiency and high consumption. In the design process, this machine fully combines the features of flow drying such as air drying and avoids weaknesses, so that the whole machine has a reasonable process structure and superior performance, and it truly achieves the objective of low consumption and high efficiency of fluidized drying.
The machine has a wide range of applications and can be used for drying of fine powder materials such as silicon carbide, black silicon carbide, green carbon silicon, black carbon silicon micro powder, green silicon carbide micro 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 agitating and crushing drying room from the bottom of the dryer through a suitable spouting speed at the air inlet, and the material is strongly sheared, blown and rotated, and then the materials are micronized by centrifugal, shearing, collision, and friction. Enhanced mass transfer and heat transfer. At the bottom of the dryer, large and wet particles are broken mechanically by the stirrer. Particles with lower moisture content and smaller particle size are entrained by the swirling airflow and further dried during the rise, due to the gas-solid phase. For rotary flow, the inertia of solid phase is greater than that of gas phase, the relative velocity between solid and gas phases is large, and the heat transfer effect between two phases is strengthened, so the drying intensity of the machine is high.


Engineering advantages:
1. With strong professionalism, large amount of processing, and fast drying rate, the surface area of the material liquid after atomization is greatly increased. Under the vacuum state, the drying time is greatly reduced. 2, the device structure is simple, no wearing parts, low maintenance costs. 3, the operation is simple and stable, easy to control, can achieve intelligent operations. 4, the use of different boiling temperature, liquid-liquid separation. 5, the use of special non-standard design of the atomizer, atomization, separation effect is good. 6, set chemical reaction, drying and integration, one-time reaction, drying, optimize equipment performance.
