Paper making machinery is a machinery that includes the preparation of raw materials, pulping, papermaking, until they are made into rolls or flat sheets, as well as the processing of paper and paperboard. The papermaking industry consumes a large amount of raw materials, water, electricity, and chemical drugs, and generates a large amount of wastewater and waste residue. Therefore, the future of papermaking machinery will develop towards using a wide range of papermaking raw materials, reducing material and energy consumption in the papermaking process, and reducing environmental pollution.

Statistical data from the China Paper Machinery Parts Industry Association show that in the first two quarters of 2011, the year-on-year growth rate of sales revenue and sales in the construction machinery industry slowed down, and the decline was significant. The purpose of low power consumption and less fiber loss is suitable for some large industrial and mining enterprises. Paper making machines have strict requirements for such devices.
