Liuzhou, located in the northeast of the central part of Guangxi, is known as the "commercial port in Guangxi".  It is not only an important railway hub connecting southwest China with central and southern China, east and South China, but also an important node connecting the "One Belt and One Road" and a leading city and core city in the Central and Western River Economic Belt of the western Development strategy.  

At present, the mining of limestone resources in Guangxi is basically in the state of low value-added processing, mostly used for construction aggregate, marble and primary cement, low value-added production and processing of calcium carbonate and other projects, and there are problems such as backward technology and equipment, unscientific product structure, and difficult to enter the field of high-end product processing and use.  

For the positive response of guangxi industrial high quality development plan of action, to carry out the "second venture" traditional industry, building innovation ability is stronger, deeper and better supply higher quality, industrial structure and better economic benefit and less resource consumption of traditional industries new business CARDS, chongqing three inscription heavy industry in guangxi liuzhou user intends to adopt the domestic advanced technology,  To build a production base for limestone industrial series products with high output, high scale and advanced technology.

◎ Project Highlights:  

This fine sand aggregate production line adopts chongqing Sanming Heavy Industry's two-stage crushing + one-stage sand making + three-stage screening process scheme, which has multiple advantages:  

* Flexible production can be realized, the proportion of gravel and fine sand output can be adjusted, according to the market demand and product prices, users can adjust themselves, in order to improve the economic benefits of enterprises.  

* Machine-made sand aggregate has excellent grain shape, continuous gradation, reasonable fineness modulus and dust content, which can simultaneously meet the different needs of dry mortar, commercial concrete, asphalt concrete and high performance concrete.  

* Packaging and sales of machine-made sand products to improve quality and facilitate dust-free transportation.  

The production line is equipped with advanced and efficient mining equipment and adopts step mining mode to carry out mining restoration and reclamation work synchronously.  At the same time, the use of domestic advanced central control management system, cloud monitoring system, etc., to realize the whole process of mining and production of intelligent, environmental protection, and strive to build a green building materials industry concentration area as soon as possible.  

Across the country to speed up the large sand machine production base and processing and distribution center construction, chongqing three inscription heavy industry co., LTD., paying attention to national policy changes, to grasp core technology industry, constantly improve product performance, adhering to the "integrity, pragmatic, innovative" business philosophy, around the "smart, high efficiency, energy saving, environmental protection" product market positioning,  Committed to providing customers with intelligent green sand aggregate system overall solution, hand in hand to build a model of green mine, help the sand and stone industry high-quality development.
