China Drying Net Nanjing Sanpu Granulation Equipment Co., Ltd. has developed a new type of high-yield sulphur granulator, rotary trumpet granulator, which has sold nearly 30 sets since its launch on the market. After a long period of application inspection and further technical improvement, the granulator has now formed a 15/20/25/30 tons/hour specification equipment product, and the maximum single-machine capacity is 5 times that of the steel belt granulator.
The steel strip type sulfur granulator has been applied to the sulfur recovery process for nearly 20 years, and the processing capacity of a single unit is small. With the rapid growth of China's refining capacity, the new project is basically 10 million tons. Due to the large amount of imported crude oil, the sulfur content is relatively high, and the sulfur recovery capacity of each refinery reaches 200,000 to 300,000 tons/year. Refining companies urgently need a single sulfur granulator with a significant increase in production capacity to meet the demand for plant sulfur recovery. Nanjing Sanpu sharply captured this market information and developed a new type of large-capacity rotary drum granulator for three years. Its maximum single-product capacity is five times that of the steel belt granulator.
Compared with the steel belt granulator, the rotary drum granulator does not need to replace large wearing parts, and the loss of the ton product equipment is only 1/20 of the former, and the continuous long-term running time is longer. If the equipment is operated at 8,000 hours/year, a steel belt granulator needs to be replaced with steel strips in 1~2 years at a cost of 400,000 to 450,000 yuan. However, the annual cost of equipment and spare parts for rotary drum granulators is only It is 20,000 yuan/year. At the same time, the main part of the drum granulator is only 1/3 of the floor area of ​​the steel belt granulator, which can save the company more investment in infrastructure and other infrastructure. In addition, the selling price of rotary granulator is only 1/2 of imported equipment of the same type abroad, which can save a lot of money for the company.
Revised Chain and Escalator Step Chain,Comprising a plurality of link units interconnected in series with each other, each of the link units comprising pairs of inner links in parallel with each other, arranged in pairs and in parallel with each other for connecting two adjacent link units And a steel wheel rotatably provided on the steel wheel shaft, characterized in that the link unit further comprises a traction main wheel, the traction main The wheel is provided on the steel wheel shaft and the outer diameter of the traction main wheel is larger than the outer diameter of the steel wheel. Since the outer diameter of the traction main wheel is larger than that of the steel wheel, the steel wheel plays a supporting role when the cascade Chain is driven by the drive steel wheel, and the main wheel takes the active action, so that the violent friction between the steel wheel and the transmission wheel can be avoided , Significantly extending the service life of the steel wheel and effectively protecting the transmission wheel, and the noise in the cascade chain movement is significantly reduced.
