Project Overview:

Silicon carbide (SiC) is the use of quartz sand, petroleum coke (or coal), wood chips as raw materials from high temperature smelting resistance furnace. Silicon carbide also exists in the rare minerals of nature, Mozambique. Silicon carbide, also known as carborundum. In the modern C, N, B and other non-oxide high-tech refractory materials, silicon carbide is the most widely used, the most economical one. Can be called grit or refractory sand. At present, China's industrial silicon carbide production is divided into two kinds of silicon carbide and green silicon carbide, are hexagonal crystal, 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 drying inefficient, high consumption and research and development of new efficient fluidized drying equipment. The aircraft in the design process fully combined with air drying and other drying characteristics of the flow, and avoid weaknesses, so that the machine has a reasonable structure and excellent use of performance, truly fluidized dry low-cost, high efficiency goals.

The machine has a 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 powder, green silicon carbide 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 chamber, the material strong shear, blowing floating, rotating role, so the material by centrifugation, shear, collision, friction and was micronized, Enhanced heat and mass transfer. At the bottom of the dryer, the larger particles of wet particles are mechanically broken by the agitator, the moisture content is low, the particles with small particle size are entrained by the rotating airflow, and further dried during the rising process. Solid phase inertia is larger than gas phase, solid-gas two-phase relative velocity is bigger, strengthens the heat transfer effect between two phases, so this machine has high drying intensity.

Engineering advantages:
1, strong professional, large capacity, fast drying rate, liquid by the atomization of the surface area greatly increased, in a vacuum state, the drying time is greatly reduced. 2, the device structure is simple, non-wearing parts, low maintenance costs. 3, simple and stable operation, easy control, intelligent operation can be achieved. 4, the use of different boiling temperature, liquid-liquid separation. 5, the use of special non-standard design of the atomizer, atomization, separation effect. 6, a set of chemical reactions, drying and integration, one-time completion of the reaction, drying, optimizing equipment performance.
