Henan Liming Heavy Industry Science and Technology Co., Ltd. is a joint-stock company that focuses on the production of large and medium-sized crushing mills and integrates research, development, production and sales. The company is headquartered in the National Hi-Tech Industrial Development Zone in Zhengzhou and covers an area of ​​about 30,000 square meters. It has several wholly-owned subsidiaries under its jurisdiction. Its domestic annual sales exceed 140 million yuan, and the foreign exchange earned through exports reaches 6.8 million US dollars annually. Since its establishment in 1987, the company has been adhering to the scientific management methods of modern enterprises, manufacturing with precision, continuous innovation, and has rapidly grown and become a shining pearl in China's machinery manufacturing industry. Raymond Mill equipment continues to evolve, starting with the 2R Raymond Mill, the improved high-pressure micropowder mill on the basis of Raymond Mill, and Liming Heavy Industries' patented high-pressure suspension mill and Ultra Pressure trapezoidal milling machine. Liming Heavy Industry Products has passed IS09001: 2000 international quality system certification, YGM, TGM series mill has passed the European Union CE certification, and successfully entered the EU market. The experts from Henan Science and Technology Department unanimously determined that the double-use super-pressure trapezoidal mill has reached the domestic leading level, won the Henan Provincial Science and Technology Achievement Award, and the super-pressure trapezoidal mill patent number: ZL200520030288.3 currently used Raymond Mill, the feed size and The output is limited. The material is usually broken by a jaw crusher to achieve the required feed size of the mill. It can be fed into the milling machine for milling. The material yield is low and the dust pollution is serious. This phenomenon has been a major challenge for milling equipment manufacturers to overcome.
Henan Liming Heavy Industries Raymond Mill (abbreviated as Raymond Mill) has the advantages of cost-effective products, first-class equipment quality, high production yield, and high-efficiency skills. It is a leading manufacturer of large-scale milling machines. Some products are exported to India, Vietnam, Indonesia, Malaysia, Laos, Egypt and other countries and regions, and enjoy a high reputation both at home and abroad. Raymond Mills, High-Pressure Ultrafine Powder Mills, High-Pressure Ultrafine Powder Mills, High-Pressure Medium-Speed ​​Mills, High-Efficiency Centrifugal Mills, Powerful Mills, Ultrafine Powder Mills The development of the milling industry requires the development of a patented device with multiple intellectual property rights, which has created a new era of high efficiency and low energy consumption in international industrial milling. In order to meet users' requirements for processing different rock, fineness, yield, and use, and different process requirements, in line with local conditions, optimizing investment scale, and aiming at achieving the best economic benefits for investors, it is an industrial mill production project. , Henan Liming Heavy Industry Engineering and technical personnel to the site of the user to carry out on-site survey, planning, design process, and is responsible for the late installation and commissioning and maintenance services.
The technological innovation of China's construction machinery companies, especially the original technological innovations, has exerted arduous labor and tremendous efforts. In the new historical period, China's flour milling machinery industry is moving toward establishing a world-class Chinese brand, becoming a truly competitive partner and standing in the world's counterparts and making unremitting efforts. Raymond Mill produced by Liming in Henan Province adopts a new design principle, adopts a new concept of grinding technology, introduces advanced German technology, and owns a new generation of mill products with independent patent property rights, which can meet the requirements of different material specifications. The new mill technology is superb, creating a new era of efficient industrial milling and low energy consumption.
In recent years, with the rapid development of the pulverizer industry, a number of elite enterprises have emerged. The research and development of powder technology in powder production, application and equipment manufacturing in China has progressed at a rapid rate. New equipment and new products are continuously available. Appearing in the market shows strong vitality and vitality. Henan Liming Heavy Industry Science and Technology Co., Ltd. is a company that mainly researches and develops crushers, mills and sand makers. Since the establishment of the company, the company has been at the forefront of grinding machine technology, and has developed foreign advanced technologies from the earliest date. Ball Mill, Raymond Mill, High-Pressure Micropowder Mill, etc.; now fully independent patented overpressure trapezoidal mills, straight-through centrifugal mills, high-pressure suspended mills and other equipment, step by step China Mill technology has pushed the world's technology frontier.
