Silicon Carbide Drying Production Line
Project Name：Silicon Carbide Drying Production Line
Project Overview:
Silicon carbide (SiC) with quartz sand, petroleum coke (or coal), wood chips as raw material made by electric arc furnace smelting. There are also rare in nature, silicon carbide mineral, Moissanite. Silicon carbide, also known as moissanite. In modern C, N, B and other non-oxide refractory materials in high-tech, silicon carbide is the most widely used, the most economical. Can be called corundum or refractory sand. At present, China's industrial production is divided into black silicon carbide and silicon carbide green silicon carbide two, are hexagonal, accounting for 3.20 ~ 3.25, microhardness of 2840 ~ 3320kg/mm2.
Equipment Overview:
Silicon carbide production line drying is inefficient companies to overcome the static drying, high consumption and developed new and efficient fluidized drying equipment. Aircraft fully integrated in the design process and drying air flow characteristics of the dry state, avoid weaknesses, so that the whole process with a reasonable structure and excellent performance, truly fluidized dry low, high goals.
Extremely wide range of applications of this machine can be used for silicon carbide, black silicon carbide, green silicon carbide, carbon black and silica, green silicon carbide powder, foam ceramic silicon carbide, silicon carbide and other refractory small proportion of the fine powder drying. Equipment, high thermal efficiency, low energy consumption, small size, configuration is simple, convenient control.
How it works:
Hot air from the inlet to the appropriate rate from the dryer spouted mixing crushed into the bottom of the drying chamber, the material strong shearing, blowing, floating and rotating effect, so the material by centrifugation, shear, impact, friction has been micronized, enhanced heat and mass transfer. The bottom of the dryer, the wet particles larger than the group under the action of the agitator mechanical crushing, low moisture content, particle size smaller particles are rotating air entrainment increase, rising further during drying, due to gas-solid flow in rotating inertia is greater than the gas-solid phase, solid-gas relative velocity between two phases of a larger, enhanced heat transfer between two phases, so the machine dry and high strength.
Engineering advantages:
1, highly specialized, large capacity, drying rate, and liquid atomized by the greatly increased surface area, in a vacuum, the drying time is greatly reduced. 2, the device structure is simple, no wearing parts, maintenance costs low. 3, simple and stable, easy to control, intelligence operations can be realized. 4, the use of different boiling temperatures, to achieve liquid-liquid separation. 5, using special non-standard design of the atomizer, atomization, separation is good. 6, the set of chemical reactions, dry and one, one complete response, drying, optimize equipment performance.
