Project Overview:
Silicon carbide (SiC) with quartz sand, petroleum coke (or coal), wood chips as raw material in electric arc furnace smelting. There are also rare in nature, silicon carbide mineral, Moissanite. Silicon carbide, also known as Moissanite. In contemporary C, N, B and other high-tech non-oxide refractory raw material, silicon carbide is the most widely used and most economical one. Can be called emery or refractory sand. At present, China's industrial production is divided into black silicon carbide and silicon carbide green silicon carbide two kinds, both hexagonal crystal, specific gravity of 3.20 ~ 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 in the design process to fully integrate air drying, etc. fluidized drying characteristics, weaknesses, so that the whole process has a reasonable structure and superior performance, truly fluidized dry low consumption, high goals.
The machine is extremely wide range of applications that can be used silicon carbide, black silicon carbide, green silicon carbon, black carbon silica, green silicon carbide powder, foam ceramic silicon carbide, silicon carbide and other refractory small proportion of fine powder material drying. Equipment, high thermal efficiency, low energy consumption, small footprint, simple configuration, convenient control.
How it works:
Hot air from the inlet to the appropriate speed from the spout into the bottom of the dryer stirring and crushing and drying chamber, the material strong shearing, blowing, floating and rotating effect, so the material by centrifuge, shearing, impacting and friction being atomized, enhanced heat and mass transfer. In the bottom of the dryer, a larger group than the wet granules under the action of the agitator is crushed, low moisture content, particle size smaller particles are rotating air entrainment rise further in the process of drying up due to gas-solid phase flow in rotating inertia of solid phase than gas, solid-gas relative velocity between the two phases is large, enhanced heat transfer between the two phases, so the machine dry and high strength.
Engineering Advantage:
1, professional and strong, large capacity, drying rate, after the spraying liquid surface area increased significantly, under vacuum, drying time is greatly reduced. 2, the device structure is simple, no wearing parts, maintenance costs low. 3, simple operation, stable and easy to control, can realize intelligent operation. 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, set a chemical reaction, drying and one, one-time completion of the reaction, drying, optimize equipment performance.
