Silicon Carbide (SiC) is one of the most popular high performance tribo-materials, which has been commercially available for more than twenty-five years. Its features include:
· Excellent abrasion and wear resistance
· Excellent corrosion resistance
· Low coefficient of friction
· Low coefficient of thermal expansion
· High thermal conductivity
· Hardness greater than Tungsten Carbide
Different grades of Silicon Carbide are available as following:
· Reaction Bonded Silicon Carbide (RB SiC) - a very economical material which gives excellent wear characteristics, as well as good chemical resistance.
· Sintered Silicon Carbide (SSiC) - the absence of free silicon makes it most resistant to chemically-aggressive fluids, and ideal for high temperature applications.
· Graphite-Loaded Silicon Carbide - this is a composite of silicon carbide and free graphite. Graphite is added to RB SiC (RB SiC + C) or SSiC (SSiC + C), to improve tribological behavior by enhanced lubricity.

Soybean Dryer is an ideal drying equipment to dry grain and oilseeds, soybean is input to the top by bucket elevator, through the feeding device, to ensure that the equipment during operation is always in full load condition. Induced draft fan introduce hot air into inside of the tower body, through the combined effects of inwardly inverted V-
shaped baffle bottomless and processing and staggered rows of V-shaped baffle, so that soybean can be mixed with hot air, as well as dry air access routes, a majority of dried air can be recycled, water vapor generated by drying the material discharged from the dryer exhaust system, it consumes very little fuel. 5HY series low-temperature batch circulating soybean dryer adopts low temperature drying method to achieve drying.
Soybean dryer is designed by Hongyun based on many advantages of domenstic dryers and foreign dryers.Long-term production practice proves that this soybean dryer has advanced technology and reasonable structure. It has many advantages such as good drying quality, less energy consumption, low investment, high adaptability and so on. It is suitable for drying corn, rice, sorghum, wheaat, barley, soybean and other crops.
