Guiyang is located in the middle of the Qianshan Plain hills, which belongs to the typical karst landform fully developed mountainous terrain. In Guizhou, all large, medium and small projects involving infrastructure construction, including real estate development, inevitably involve a large number of stone blasting and excavation, so a large number of waste rock accumulation and low-value low-lying landfills have also been generated, resulting in a great waste of resources.

It is to see that this regional business opportunity is untapped.At the beginning of this year, the customer in Guizhou purchased a set of crawler mobile crushing and screening equipment of BORGERS, including mobile impact crusher BGI1040RS and mobile screening plant BGS500, to process the waste stone excavated from the foundation excavation in the process of real estate development into high value-added building aggregate (0-31.5mm), which can turn waste into treasure and realize the recycling of resources while achieving good economic benefits. The customer uses this set of equipment under the flight take-off and landing routes of Guiyang Airport, and the equipment comes with dust-proof and multi-automization spray dust removal devices, which can ensure the dust removal effect when working, and can meet the high environmental protection requirements of construction under the airport take-off and landing routes.

After processing all the waste rock accumulated on the site into sand and gravel aggregates, the customer immediately transferred this mobile production line to a rural road construction site in Anshun, Guizhou Province, to process aggregates smaller than 45mm for the owners of road repairs, and then mix them for water stabilized materials for roads, with an hourly production capacity of up to 150 tons.

The reason why the highway construction owner rented this mobile aggregate production line from a customer in Guizhou is that the site is narrow, it is difficult to arrange the fixed line, and the construction period is short, and it is too late to carry out the necessary infrastructure for the complicated fixed line such as field leveling, concrete foundation, steel structure, belt conveyor, and application for overhead line electrification. By selecting the nearest quarry point and carrying out aggregate production and mixing nearby, the rapid supply of water-stabilized materials is guaranteed, the transportation cost of materials and engineering construction costs are greatly reduced, and the project profitability of highway construction owners is improved.

It is through the successful operation experience of the above two construction sites and the value-added services brought by them that the customer in Guizhou ordered the crawler mobile jaw crusher BGJ1350 and the crawler mobile impact crusher BGI1040 at the end of the year.

The customer used the BGJ1350 and BGI1040 machines to process the rocks after the blasting of the limestone mountain into subgrade bottom filler and water-stabilized material when the customer used the new plant of Guizhou Geely Automobile. The adoption of the two-stage crushing process of crawler jaw crusher + crawler impact crusher has greatly increased the production capacity and reduced the wear cost. The finished aggregate has a particle size of 0-70mm mixture, and the capacity can reach 260 tons per hour. The customer brings its own excavator and loader to cooperate with the production, the operating ton cost of the four pieces of equipment does not exceed 6 yuan, the processing fee of finished aggregate is 22 yuan per ton, the working hour is 12 hours a day, and the monthly customer can make a profit: 25 (day/month) x 12 (hour/day) x 260 (ton/hour) x [22 (processing fee per ton)-6 (cost per ton)] = 1,248,000 yuan.

Since the customer has blasting qualifications and has excavators, drilling rigs, air compressors and other auxiliary machinery, since the purchase of the mobile production line of Terex South Road Machine, it has effectively supplemented the profitability of its traditional business, and its aggregate processing business is booming.

BORGERS tracked mobile crushing and screening equipment has significant advantages such as easy mobility, energy saving and environmental protection, high production efficiency, low operating costs, and fast and flexible on-site layout. The Guizhou customer has purchased a total of 4 mobile crushing and screening equipment for BORGERS within one year, which is a strong proof of the stable performance, high cost performance and good after-sales service of BORGERS.
