Project Overview:

Silicon carbide (sic) is made of quartz sand, petroleum coke (or char), sawdust as raw material through resistance furnace high temperature smelting. Silicon carbide also exists in the nature of rare minerals, moissanite. Silicon carbide is also known as carbon silica. In contemporary C, N, B and other non-oxide high-tech refractory materials, silicon carbide is the most widely used, the most economical one. Can be called golden steel sand or refractory sand. At present, China's industrial production of silicon carbide is divided into black silicon carbide and green silicon carbide two, are six square crystals, the specific gravity of 3.20~3.25, micro-hardness of 2840~3320kg/mm2.

Device Overview:

sic drying production line is our company to overcome static drying inefficient, high consumption and developed a new high-efficiency fluidized drying equipment. The machine in the design process fully combined with the characteristics of air drying and other flow drying, to avoid weaknesses, so that the machine has a reasonable process structure and superior performance, the real realization of fluidization drying low-cost, efficient target. the machine is widely used in silicon carbide, black silicon carbide, green carbon silicon, black carbon silicon powder, green sic powder, foam ceramic silicon carbide, refractory silicon carbide and other small proportion of fine powder material 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 inlet to the appropriate jet speed from the bottom of the dryer into the stirring and crushing drying chamber, the material of strong shearing, blowing, rotating action, so the material by centrifugation, shearing, collision, friction and was particulate, enhanced mass transfer heat transmission. At the bottom of the dryer, larger and more wet particles are mechanically broken under the action of the agitator, the particles with lower wet content and smaller particle size are increased by the rotating airflow, and further drying in the rising process, due to the gas-solid rotation flow, solid-phase inertia is greater than the gas phase, solid gas two phase relative speed, strengthen the heat transfer effect So the machine has high drying strength.

Engineering Advantages :

2, the equipment structure is simple, no wearing parts, low maintenance costs.

3, simple and stable operation, easy to control, can realize intelligent operation.

4, using different boiling point temperature, to achieve liquid-liquid separation.

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

6, set chemical reaction, drying and integration, one-time complete reaction, drying, optimize equipment performance.
