Guizhou Rongshenglihe Industrial and Mining Equipment Manufacturing Co., Ltd. is a subsidiary of the limited company. Shanxi Shanli Buna Rubber Belt Co., Ltd. is a project for investment promotion in Xiangyuan County, Changzhi, Shanxi Province. It was settled in Fuyang Industrial Park of Xiangyuan in early 2012. A construction project that relies on the new coal chemical industry chain of circular economy, fully utilizes the local new coal chemical raw coal - coal washing - power generation - chemical - rubber products, and further extends the industrial chain through comprehensive utilization. This project adopts German imported production line technology and domestic equipment, implements a modern management system, and strives to create a complete range of scientific and technological new composite material bases in the same industry in China. Rubber conveyor belts are the second largest rubber industry product after tires, mainly used for material transportation in coal, docks, metallurgy, machinery, and warehousing industries. Shanxi is a major coal province, and the demand for mining conveyor belts is particularly prominent. Shanli Platinum Rubber Machine Belt Co., Ltd. has mature technology and unique geographical advantages. As one of the links in the circular economy industry chain, it has achieved a true cycle of coal chemical products. The company mainly produces PVC, PVG whole core flame-retardant conveyor belts, layered flame-retardant conveyor belts, strong wear-resistant conveyor belts, heat-resistant conveyor belts, steel wire core conveyor belts, steel wire core tear resistant flame-retardant conveyor belts, ordinary core conveyor belts, circular conveyor belts, NN nylon conveyor belts, EP polyester conveyor belts, heat-resistant conveyor belts, EP100-400 high-temperature conveyor belts, circular conveyor belts, corrugated edge conveyor belts, acid and alkali resistant conveyor belts, patterned conveyor belts Oil resistant conveyor belts, steel wire tear resistant conveyor belts, steel wire spiral mesh conveyor belts, parallel transmission belts, rubber waterstops, etc. Among them, as the main products, the ordinary type (heat resistant, * force type), steel wire rope core, and flame retardant type, all three series of whole core flame retardant belts have an annual production capacity of 700000 meters. The company also produces a series of mining water pipe products, including polyethylene (PE) water supply pipes, steel wire mesh skeleton (PE) pipes, steel wire mesh skeleton polyethylene composite pipes (SRPE), high-density polyethylene double wall corrugated pipes, high-pressure pipes, polyethylene pipes for gas use, steel strip reinforced polyethylene (PE) threaded corrugated pipes for buried sewage discharge, polyethylene winding structure wall corrugated pipes, and various products in the field of mechanical manufacturing, such as conveyors and scraper machines.
