The controlled-release fertilizer project was introduced by Hengli Chemical from the Chinese Academy of Agricultural Sciences. The total investment of the project was 165 million yuan. Construction started at the end of 2009. After 10 months of intense construction, a total of slow-release fertilizer was built. , Compound fertilizers, organic-inorganic compound fertilizers, compound microbial fertilizers, slow-release blending fertilizers and other 6 modern production lines. The completion and commissioning of this project will play an active role in improving the chemical industry chain of Guang'an, promoting agricultural development, and accelerating the industrialization process. It is reported that the slow-release fertilizer has the characteristics of one-time crop fertilization, labor-saving time, high utilization rate, and high economic efficiency. It can effectively reduce the volatilization, leaching and denitrification of fertilizers, and reduce the environmental pollution caused by fertilization. It is widely used. In Daejeon agriculture, vegetables, flowers, lawns, etc., is currently recognized as an environmentally friendly fertilizer in the international agricultural community.
Hengli Chemical Co., Ltd. introduced slow-controlled release fertilizer production technology and technology, making the company a national high-tech enterprise integrating research and development, production and sales of various new fertilizers, and the largest research and development of controlled-release fertilizer and compound microbial fertilizer in southwest China. Base, in 2010 the company's Fertilizer Engineering Technology R&D Center was identified by the National Development and Reform Commission as the “National High-tech Industrialization Demonstration Projectâ€. At present, the company will implement second-phase slow-release fertilizer and other fertilizer projects, and after the completion of the project, the annual production capacity will reach 1 million tons.
A concrete mixer is a machine that mixes cement, sand and aggregate with water to make a concrete mixture. It is mainly composed of mixing drum, feeding and unloading mechanism, water supply system, prime mover, transmission mechanism, frame and supporting device, etc. According to the nature of work, intermittent type (batch type) and continuous type; According to the stirring principle, it is divided into self-falling type and forced type. According to the installation of fixed and mobile; According to the way of discharging, tilting type and non-tilting type; According to the structure of the drum, it is divided into pear type, drum type, double cone, disc vertical shaft type and round groove horizontal shaft type.
