Uses: For delivery of sintered ore, coke, cement clinker and other high-temperature materials. Pitting conveyor belt characteristics: high temperature, anti-aging, acid, weathering resistance, can be used in a sunny, humid environment for a long time, not cracking early aging with interlaminar adhesion strength, the process of using does not appear blistering, delamination phenomenon. Convex conveyor T3 use temperature ≤ 150 ° C; and T4 use temperatures ≤ 180 ° C. Convex conveyor belt implementation of standards: HG/T2297 (T3-type), HG/T2297 (of T4 type) standard is used to transport food crops, chemical products, such as peanuts, corn, rice, wheat, soybeans, and other ancillary products of medium and small particle size of the material equipment which is characterized in the transportation process, at different times, in different parts of throughput relative to the average. Can be used to require a higher food production, processing, storage, and chemical fertilizer, chemical, medical goods transported.
