Silicon carbide drying line

Project Overview: Silicon carbide (SiC) is smelted
from quartz sand, petroleum coke (or coal coke) and wood chips through high temperature in a resistance furnace.

Silicon carbide also exists in large naturally rare minerals, moissanite
.

Silicon carbide is also known as moissanite
.

In the contemporary C, N, B and other non-oxide high-tech refractory raw materials, silicon carbide is a widely used and economical one
.

It can be called gold steel sand or refractory sand
.

At present, the silicon carbide produced in China's industry is divided into two kinds: 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: Silicon carbide drying production line is a new type of high-efficiency fluidized 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 flow drying such as airflow drying, promotes the strengths and avoids the shortcomings, so that the whole machine has a reasonable process structure and better performance, and truly achieves the low consumption and high efficiency goal
of fluidized drying.

This machine has an extremely wide range of applications and can be used for silicon carbide, black silicon carbide, green carbon silicon, black carbon carbide micro powder, green silicon carbide powder, foam ceramic silicon carbide, refractory silicon carbide and other small proportion fine powder materials drying
.

The equipment has high thermal efficiency, low energy consumption, small footprint, simple configuration, and convenient
operation and control.

Working principle: Hot air from the air inlet at a suitable spraying speed from the bottom of the dryer into the stirring and crushing drying chamber, the material has a strong shearing, blowing and floating, rotating effect, so the material is centrifuged, sheared, collided, friction and particleized, strengthening mass transfer and heat
transfer.

At the bottom of the dryer, the larger and weter particles are mechanically broken under the action of the agitator, the particles with lower wet content and smaller particle size are entrained by the rotating air flow, and further dried in the process of rising, because the gas-solid phase is rotating flow, the inertia of the solid phase is greater than that of the gas phase, and the relative speed between the solid-gas phases is larger, and the heat transfer effect between the two phases is strengthened, so the drying strength of the machine is high
.

Engineering advantages: 1, strong professionalism, large processing capacity, fast drying rate, the surface area of the material liquid after atomization is greatly increased, in the vacuum state, the drying time is greatly reduced
.

2.
The equipment structure is simple, there are no wearing parts, and the maintenance cost is low
.

3.
Simple and stable operation, convenient control, and intelligent operation
.

4.
Use different boiling point temperatures to achieve liquid-liquid separation
.

5, the use of special non-standard design of the atomizer, atomization, separation effect is good
.

6.
Integrate chemical reaction, drying and integration, complete the reaction and drying at one time, and optimize the performance
of the equipment.
