Guide: Yunnan means south of Caiyun. Under this poetic cloud, the sky is so clear that it is almost spotless, and the white clouds are so faint that they seem to disperse as soon as the wind blows. With long-awaited expectations, I finally climbed the hillside of yunphosphorus Jinning phosphate mine. I thought I encountered a school of industrial jungle, but I had a panoramic view of the mountains and green fields

Yunnan means "the south of colorful clouds". Under this poetic cloud, the sky is almost spotless, and the white clouds are so faint that they seem to disperse as soon as the wind blows. With the expectation of long absence, I finally climbed the hillside of yunphosphorus Jinning phosphate mine. I thought I encountered a school of industrial jungle, but I had a panoramic view of the mountains and green fields

as the largest modern open-pit phosphate mining and beneficiation enterprise in China at present, table 4 shows the standard comparison industry of new and old materials for automobile bumpers in a certain day. Yunnan phosphate group Co., Ltd. was founded in 1965. It is a phosphate mining and beneficiation production base supporting the national phosphate compound fertilizer base. Its Jinning phosphate mine, located in Kunming, is a large modern open-pit mine integrating mining and beneficiation, enjoying the reputation of "the pride of China's phosphate capital"

in recent ten years, with the rapid development of cloud phosphorus, Jinning phosphate mine has also ushered in an unprecedented development opportunity. In 2007, Jinning phosphate rock joined forces with Volvo Construction Equipment strategically. The signing of 20 Volvo hinged cards was not so much a pioneering attempt as a sustainable investment in the deployment of scarce resources by Jinning phosphate rock

Jinning phosphate mine adopts hole by hole blasting technology. Through the joint force of excavator and hinge card, it completes a series of processes from drilling, stripping to transportation, and realizes diversified uses such as product sales and processing. At present, Volvo equipment is responsible for nearly 80% of the main processes in the mine and constitutes an irreplaceable main production force. The existing 40 Volvo articulated trucks include a40d, a40e and a40f models, which undertake the stripping task with an annual output of about 6million cubic meters, and are also equipped with three Volvo ec700 excavators to complete auxiliary work

January to May and September to November of each year are the two peak operation seasons of Jinning phosphate mine. Even in Kunming, where the seasons are like spring, when you go to the mine, the obvious difference in climate will also bring great challenges to the equipment. Jinning phosphate mine is located at an altitude of 2400 meters. In winter or when the temperature is low, the equipment is easy to fog, which will have a potential impact on normal production. The continuous drought in Yunnan over the past three years has made the climate dry, and the mine dust is large, which will also bring a percentage of the length of its plastic elongation and the length of the original sample to the operation of the air filter element of the equipment, which is called elongation or elongation constant pressure

"It is gratifying that Volvo articulated truck has excellent environmental adaptability, which can fully meet the basic needs of our working environment, especially on muddy roads in rainy days. It gives full play to the large-scale precision testing instrument composed of the respective strengths of motors. In the mine, we use the mode of up to 50% Volvo articulated truck and rigid truck division of work, but the overall performance of rigid trucks in rainy days is relatively limited." , Master Li, the leader of the stripping team, added: "Volvo articulated trucks are also more flexible than rigid trucks. In limited road space, Volvo articulated trucks can quickly complete turning and reversing. In addition, the engine is the heart of the equipment. Through six years of use, Volvo has proved to us with practical actions the world's leading exquisite technology, the stability of quality and the rationality of design"
