Matching with production capacity; digitalization, automation, and real-time management of key indicators of shoveling and transporting crushing process, realizing quantitative linear management of human-machine efficiency and cost management; application of integrated quality, blasting, and distance management system to achieve resource integration Optimization of utilization rate, precision of quality control, controllability of distance and cost management.
Now its transformation effect is obvious. In 2015, its mining management technology was listed by the Ministry of Land and Resources as “the fourth batch of advanced demonstration technologies for the conservation and comprehensive utilization of mineral resources”; its digital management technology application won the National Building Materials Industry Technology Innovation Award in 2016.

In the selection of equipment, the Yuebao Mine not only comprehensively considers the factors such as the efficiency, service life, and use cost of the equipment, but also meets the important criteria for the construction of green mine concepts. Liebherr's R984C has extensive applications in cement mines, metal mines, and chemical mines in China. Among the many mine customers in China, the longest working hours have exceeded 30,000 hours. As an upgrade product for R984C, the R9100 is more in line with the habits of Chinese customers - weighing 110 tons, bucket capacity of 7 cubic meters, and positioning on a 100-ton excavator.
The R9100 is equipped with a D9512 engine designed and manufactured by Liebherr. This engine is the only one of its kind in the excavator to adopt the V12 cylinder design and operates extremely smoothly; the power is up to 565kW and the fuel consumption is very economical. The hydraulic system is equipped with 3 main pumps, adopts CAN bus technology, electronically controlled pressure and flow management system, Liebherr independent rotary system design is reserved, and the rotation speed reaches 6 rpm, which improves the working efficiency of the vehicle. The vehicle cooling system uses an independent cooling module, a large radiator, and a hydraulic motor to drive the fan. The cooling efficiency is greatly improved but the power consumption is reduced by about 40%. The cab area has increased by 20% and it is equipped with a 10.5-inch LCD display.
This product is very suitable for loading 30-60 tons of dump trucks, according to the actual loading situation of the cement field in Vietnam, the production of up to 1200 tons per hour. Therefore, in the fierce competition, with its superior performance and outstanding performance of Liebherr products in other mines, the R9100 stands out from the customers.
The delivery of Liebherr R9100 also marks the beginning of the cooperation between China Resources Viborg Cement and Liebherr. Liebherr’s cooperation with Vietnam’s cement began 12 years ago. At that time, the Liebherr R914B purchased from Viejo Cement was still the main equipment for mine site operations. Its engines, main pumps, and valves have never been replaced since the purchase. Or overhauled. Viejo Cement praises Liebherr's excellent, stable quality and efficient work performance. It is believed that the increase of R9100's help will continue to increase its production efficiency.
We wish that Bingbao Cement will continue to make efforts and continue to create success in the context of stable domestic economic conditions. At the same time, we will work even harder to meet the needs of our customers, provide good service guarantees, and contribute to the continuous improvement of our business. A power!
