Project Overview:
Silicon carbide (SiC) with quartz sand , petroleum coke ( or char ) , sawdust from electric arc furnace smelting . In nature there are also rare silicon carbide mineral moissanite . Silicon carbide , also known as Moissanite . In contemporary C, N, B and other non- oxide refractory materials in high-tech , silicon carbide is the most widely used and most economical one. Can be called emery or refractory sand . At present China's industrial production of silicon carbide is divided into two kinds of black silicon carbide and green silicon carbide , are hexagonal crystals, accounting for 3.20 to 3.25 , microhardness 2840 ~ 3320kg/mm2.

Equipment Overview:
SiC drying production line is the company to overcome the static drying inefficient , high consumption and developed new and efficient fluidized drying equipment. The aircraft fully integrated in the design process , such as fluidized drying air drying characteristics , weaknesses, so that the whole process has a reasonable structure and superior performance , the real fluidized dry low , high goals.
The machine is extremely broad range of applications , can be used for silicon carbide, black silicon carbide, green silicon carbon , black carbon silica powder , green silicon carbide powder , foam ceramic silicon carbide, silicon carbide and other refractory small proportion of fine powder material drying . Equipment Thermal high efficiency, low power consumption , small footprint , simple configuration, easy to operate controls .

How it works:
Hot air from the inlet to the appropriate speed spouted from the bottom of the dryer into stirring and crushing and drying chamber , the material strong shearing , blowing , floating and rotating effect , so the material by centrifugation , shear, impact, friction is atomized , strengthen the heat and mass transfer . At the bottom of the dryer , wet particles larger than the group under the action of mechanical stirrer was broken , low moisture content , particle size smaller particles entrained airflow is rotated rise in the drying process of rising further , because the gas-solid phase flow in rotating inertia of the solid phase is greater than the gas phase , the larger the relative velocity between solid and gas phases , the effect of enhanced heat transfer between the two phases , so the aircraft high dry strength .

Project Benefits:
1 , professional and strong , large capacity, fast drying rate , after atomized liquid greatly increased surface area , in a vacuum , drying time is greatly reduced. 2 , the device structure is simple, no wearing parts, low maintenance costs. 3 , simple operation and stable , easy to control, intelligent job. 4 , the use of different boiling temperatures , to achieve liquid-liquid separation. 5 , using a dedicated non-standard design atomizer , atomization , separation. 6, the set of chemical reactions, drying and integration, time to complete the reaction , drying and optimize device performance .
