Recently, the B1000 × 5576 m long-distance downward belt conveyor, designed, manufactured and installed by Jiangsu ChinaMining Heavy Equipment Co., Ltd. for the CNBM Zhangye Qilianshan Cement Plant Project, has successfully completed all commissioning assessments, passed the completion acceptance and been officially put into operation. The commissioning of this equipment opens up the main raw material transportation artery from the mine for the capacity replacement project of the 4000 t/d clinker new dry-process cement production line of Zhangye Qilianshan Cement.
Located in the desert and mountainous area of the Hexi Corridor, the Zhangye Qilianshan Cement Project features crisscross gullies, large elevation variations and complex geological conditions. It sets extremely high technical requirements for the long-distance downward belt conveyor in terms of brake control, runaway prevention, stable conveying and mountain layout. The delivered B1000-type conveyor has a total length of 5576 meters, operating under ultra-long-distance downward conveying conditions, and serves as the core equipment of the mine conveying system for the whole production line.
Faced with difficulties including rugged mountain terrain, harsh construction conditions and high risks in downward conveying condition management, the project team of Jiangsu ChinaMining carried out elaborate scheme design, structural optimization, complete set manufacturing and on-site installation & commissioning. Integrated with multiple technologies such as a reliable controllable braking system, intelligent monitoring, anti-deviation and anti-runaway protection, the equipment can realize stable and safe long-distance downward transportation of ore raw materials. Compared with the traditional truck transportation mode, it greatly reduces fuel consumption, dust pollution and transportation costs. It delivers safety, economic and environmental benefits, and conforms to the green and low-carbon development trend of mines.
During project implementation, in strict accordance with the overall arrangement of CNBM Xi’an Engineering Corporation, Jiangsu ChinaMining tightly controlled manufacturing quality, seized the construction window period in mountain areas, and advanced all work in an orderly manner including steel structure erection, belt laying, electromechanical supporting works and joint commissioning. All construction tasks were completed with high standards. The equipment smoothly passed the joint completion acceptance organized by the owner, supervisor and relevant parties, fulfilling the delivery commitment.
As a professional service provider in the field of bulk material handling equipment, Jiangsu ChinaMining Heavy Equipment has been engaged in the R&D and manufacturing of belt conveyors for long-distance, large-inclination and complex working conditions for many years, continuously providing complete conveying solutions for building materials, mining, ports and other industries. The successful delivery of this ultra-long downward belt conveyor project at Zhangye Qilianshan Cement Plant marks another benchmark achievement of the company in the field of long-distance downward conveying in the alpine mountain areas of Northwest China, further consolidating its technical and engineering advantages in ultra-long-distance belt conveyors.
Going forward, Jiangsu ChinaMining will continuously polish core equipment technologies. With reliable products and high-quality services, the company will support the intelligent and green transformation of the building materials industry and create greater value for customers.
