Project Brief:
Silicon carbide (SiC) is using quartz sand and petroleum coke or coal tar, wood chips as raw material through high temperature electric resistance furnace smelting. There is also a rare mineral silicon carbide in nature, and the mo SangShi. Silicon carbide is also called the moissanite. In contemporary C, N, B the oxide refractory raw materials in the high technology, such as silicon carbide as the most widely used, one of the most economic. Can be called corundum sand or refractory. At present, the industrial production of silicon carbide can be divided into two black silicon carbide and green silicon carbide, are the six-party crystal, specific gravity of 3.20 ~ 3.25, the microhardness of 2840 ~ 3320 kg/was.
Equipment Brief:
Silicon carbide Drying production line is my company in order to overcome the static Drying inefficient, High cost and the research and development of new type High efficient fluidized Drying equipment. The machine during the design process fully according to the characteristics of the airflow drying flow drying, foster strengths and circumvent weaknesses, make the whole machine has the reasonable structure of process and the use of superior performance, truly achieve fluidized drying of low consumption, High efficient target.
Native application range is very wide and can be used for silicon carbide, black silicon carbide, green silicon, carbon black carbon silicon micro powder, green silicon carbide micro powder, foam ceramics such as silicon carbide, silicon carbide refractory small proportion of dry powder materials. Equipment, high thermal efficiency, low energy consumption, Floor area is small, simple configuration, easy operation control.
Working principle:
Hot air from the air inlet enters from bottom of drier with suitable spouted velocity stirring drying chamber size, strong shearing, blow to raw materials and the rotation effect, so the material by centrifuge, shearing, collision and friction by particles, to strengthen the heat transfer and mass transfer. At the bottom of drier, larger than wet particles under the action of stirrer is mechanical crushing, low moisture content, the smaller the particle size, particle entrainment by the rotating flow increase, in the process of rising further dry dry, because of the gas-solid phase rotation flow, solid phase of inertia is greater than the gas phase, two phases of gas in the relative velocity is larger, effect of enhancing heat transfer in two phases, so the machine dry high strength.
The advantage of project:
1, professional and strong, large amount of Handled, fast drying speed, significantly increased after spraying the surface area of material liquid, in the condition of vacuum, the drying time is reduced greatly. 2, the equipment has simple structure, no wearing parts, low maintenance cost. 3 stable, operation simple, easy to control, which can realize intelligent operation. 4, the use of different boiling point temperature, the realization of liquid-liquid separation. 5, using special non-standard design of atomizer, atomization, separation effect is good. 6, the chemical reaction, dry dry and a body, a one-time reaction, drying, optimization of equipment performance.
