Project Overview:
Silicon carbide (SiC) is made of quartz sand, petroleum coke (or char), wood chips as raw materials through high temperature resistance furnace smelting. Silicon carbide also exists in nature, a rare mineral, Moissanite. Silicon carbide, also known as carbon silica. In contemporary C, N, B and other non-oxide high-tech refractory raw materials, silicon carbide is the most widely used and most economical one. Can be called grit 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, the proportion of 3.20 ~ 3.25, micro-hardness of 2840 ~ 3320kg / mm2.

Equipment Overview:
Silicon carbide drying production line is our company to overcome the static dry inefficient, high consumption and research and development of new high-efficiency fluidized drying equipment. In the design process, the machine fully combines the characteristics of fluidized drying, such as airflow drying, to avoid weaknesses and make the whole machine have a reasonable technological structure and superior performance, and truly achieve the goal of low consumption and high efficiency of fluidized drying.
This machine has an extremely wide range of applications. It can be used for the drying of fine powder materials with small specific gravity such as silicon carbide, black silicon carbide, green carbon silicon, black carbon silicon fine powder, green silicon carbide fine powder, foam ceramic silicon carbide and refractory silicon carbide. Equipment, high thermal efficiency, low energy consumption, small footprint, simple configuration, easy operation and control.

working principle:
Hot air from the inlet to the appropriate spouting speed from the bottom of the dryer into the mixing crushing drying chamber, the material strong shear, blowing, rotating role, so the material by centrifugal, shear, collision, friction and be micronized, Strengthen the mass transfer heat. At the bottom of the drier, the larger wet granule mass is mechanically crushed under the action of the agitator. The lower the wet content, the smaller granule particles are entrained by the whirling airflow and further dried during the ascent. Due to the gas-solid phase For the rotating flow, the solid phase inertia is greater than the gas phase, solid gas relative speed between the two phases is larger, strengthening the heat transfer between the two phases, so the aircraft dry high strength.

Engineering advantages:
1, professional, large capacity, fast drying rate, the feed liquid greatly increased the surface area after atomization, in a vacuum, the drying time is greatly reduced. 2, the device structure is simple, no wearing parts, low maintenance costs. 3, simple and stable operation, easy control, intelligent operation. 4, the use of different boiling temperature, liquid-liquid separation. 5, using a special non-standard design of the atomizer, atomization, separation is good. 6, set the chemical reaction, drying and integration, one-time completion of the reaction, drying, optimizing equipment performance.
