Limestone crushing and sand production project at the Gansu Longnan Shiban deposit with a capacity of 500 tons per hour.

This project is a key node in the network of white crushed stone production enterprises of Gansu Public Transport Construction Group, which starts in Lanzhou, is complemented by the cities of Longdong, Longzhong, and Longnan, and connects Hexi into a single line. It is also a "key demonstration project" under the "14th Five-Year Plan for the Development of Transportation and Road Economy of Gansu Province."

The project utilizes high-performance C6X jaw crushers, CI5X impact crushers, and S5X series vibrating screens from Shibang Group, ensuring high efficiency, high quality, low energy consumption, and consistent stability of the production process. Currently, the high-quality sand and gravel aggregate produced by the project effectively meets local demand and provides a stable supply of sand and gravel aggregate at a guaranteed price for key construction projects in the province, such as the Kanglue Expressway and the Tianlong Railway, effectively contributing to the sustainable, environmentally friendly, circular, and low-carbon development of the regional economy.
