Roots blower: development and crisis coexist

The Roots blower industry has been very stable since its development. However, as the market continues to promote and emerging industries continue to expand, the industry is constantly facing various challenges.

First, the new development opportunities in the traditional application industry The chemical, cement, and steel industries are the three most important applications for Roots blowers. The sales of the three have been among the top five in the industry.

In 2011, the chemical industry continued to maintain a growth trend: From January to June, the industry's added value increased by 18.9%, an acceleration of 10.4% year-on-year; from January to May, the industry's fixed asset investment actually completed 331,049 million yuan, a year-on-year increase of 13.9%. The stable growth of the chemical industry will bring good development prospects to the Roots blower market.

The large amount of fixed asset investment formed by the elimination of backward production capacity and new production capacity in the cement industry has brought huge market opportunities to the Roots blower industry. According to the statistics of China Cement Association, in 2011, 176 new dry process cement production lines were newly put into operation throughout the country, and the newly designed cement clinker production capacity was 195 million tons. Of these, 69 production lines with daily output of 5,000 tons and above accounted for 56.47% of the total new production capacity. From the start of 2010 to the 12th Five-Year Plan period, with the gradual commencement of unstarted projects and the successive launch of capacity transformation projects, the investment in fixed assets of the cement industry will continue to grow rapidly.

The Roots blower is one of the important equipments in the nonferrous and ferrous metal smelting systems and is widely used in various processes. The elimination of backward production capacity in the iron and steel industry, production capacity restraint and layout optimization will affect the demand for Roots blowers. At the same time, as the country's requirements for energy conservation and emission reduction are increasingly strict, emerging industries emerge in large numbers, such as the air separation and oxygen industry, and Roots blowers have a wide range of applications in these industries.

Then the emerging markets have developed rapidly, and the potential for water treatment, pneumatic transportation, and other potential applications is huge. The water treatment industry is the most rapidly developing industry in recent years, and the sales of Roots blowers in the industry have grown rapidly. Take Shandong Zhangqiu Blower Co., Ltd., the industrial leader of the Roots Blower, as an example. In 2009, 2010, and 2011, the sales of Roots blowers in the water treatment industry accounted for 13.23% and 16.63% of the company's operating revenue, respectively. 15.35%. In addition, the rapid growth of emerging industries such as pneumatic conveying and gas separation has also made the Roots blower industry a promising development. As a general-purpose air source device, the Roots blower has many potential applications. Once the potential market matures, the market capacity will grow rapidly.
