The innovations of Liming Heavy Industry's artificial sand production line are mainly reflected in the following aspects:

The launch of dry sand making process: Liming Heavy Industry launched the dry sand making process, which is a major breakthrough in the machinery manufacturing industry. Dry sand making does not require water to remove mud powder in artificial sand, but reduces the mud powder content through sand making machines and powder selectors, thereby ensuring the quality and grade of sand. This process is not restricted by water sources and the environment, and is particularly suitable for use in areas with scarce water resources. It also reduces production costs and is more environmentally friendly.

Application of VU aggregate optimization system: Liming Heavy Industry has a VU aggregate optimization system that turns waste into treasure. The system adopts a highly intensive tower-style fully enclosed layout, integrating sand making, particle shape optimization, and stone powder control. It can achieve the improvement of various indicators such as particle shape, grading, and powder content of artificial sand, and is suitable for crushing, screening, shaping, and sand making operations of various soft rocks, hard rocks, and construction waste. The VU aggregate optimization system has a strong processing capacity, a certain transfer storage function, and modular and easy installation, quick assembly line into the operation mode, multiple seals and dustproof, light and flexible, and strong overall versatility.

Strengthening of environmental protection design: Liming Heavy Industry's machine-made sand production line has also made significant innovations in environmental protection. For example, the dry-type floor-type machine-made sand production line adopts a fully enclosed conveying, production, and negative pressure dust removal design to reduce dust at the production site and reduce the content of particulate matter in the air. At the same time, the production line is also equipped with a humidifying agitator to ensure that the finished sand has a qualified moisture content, uniform composition, and is not easy to segregate. In addition, the silo storage monitoring and automatic telescopic discharge design also ensure that there is no overflow during the stone powder transportation process, and the dry powder storage and selection technology ensures that the stone powder is dry and clean, easy to handle and comprehensively utilized.

High-efficiency and energy-saving operation characteristics: Liming Heavy Industry's machine-made sand production line has the characteristics of high efficiency and energy saving in operation. The reasonable matching of crushing equipment at all levels and the rigorous spatial cross-layout make the production line have the characteristics of small footprint, high investment economic benefits, good quality of crushed stone, and low stone powder output rate. At the same time, the production line is also equipped with an advanced electronic control system to ensure smooth discharge, reliable operation and convenient operation of the entire process.

Flexible product adjustment capability: Liming Heavy Industry's machine-made sand production line can flexibly adjust the size of finished sand and gravel materials according to the different particle size requirements of sand and gravel aggregates in different construction periods, and can produce marketable products in a timely manner, realizing multiple uses of one line, greatly reducing project investment.
