Liming Heavy Industry's River Pebble Pulverizing Vertical Mill Technology Boosts the Upgrade of Sand and Powder Industry in Border Areas!

Xinjiang is rich in mineral resources, sand and gravel aggregate processing is one of its local traditional industries. However, restricted by issues such as low resource utilization rate and high environmental protection pressure, some building materials need to be purchased from other regions. Liming Heavy Industry's efficient and stable river pebble pulverizing production line helps increase the added value of river pebbles. The high-quality river pebble sand and powder meet the local demand for sand-powder building materials and contributes to Xinjiang's urban construction.

Recently, the on-site visit team from Liming Heavy Industry went to a customer's site less than 20 kilometers away from the China-Kazakhstan border. A large-scale vertical mill river pebble pulverizing production line built by Liming Heavy Industry has been operating continuously and stably since it was put into production in 2023, with its production capacity meeting the standard. Behind this, it is not only dependent on the high-quality grinding equipment and technology of Liming Heavy Industry, but also on the comprehensive after-sales service support and professional maintenance team.

Processed Material: River Pebble

Finished Product Fineness: 325 Mesh

Finished Product Application: Concrete, Construction Materials

Equipment Used: Liming Heavy Industry LM Vertical Roller Mill

This river pebble pulverizing production line is a project settled through local government's investment promotion efforts, mainly producing new commercial concrete admixtures, putty powder, tile adhesive and other materials. Built rapidly in line with first-class standards, the project was delivered with high quality and has been in smooth operation since its commissioning. It has broken the region's dependence on some building materials from other areas, enabling local building material enterprises to achieve self-sufficiency in sand and powder usage at higher cost performance, thus injecting new impetus into regional economic development.

The return visit team conducted a comprehensive inspection of the project site, carrying out patrol checks and providing guidance on aspects such as equipment operation data, on-site operations, and daily maintenance.

Core Advantages of LM Vertical Roller Mill

In the process of river pebble pulverizing, the grinding process directly affects the quality and production efficiency of downstream products. Liming Heavy Industry's LM series vertical roller mills integrate advanced technologies from Germany's Loesche and Pfeiffer, combined with our nearly 40 years of manufacturing experience. These mills integrate crushing, drying, grinding, classifying, and conveying functions in one unit, with multiple independent intellectual property rights. As a large-scale, high-efficiency, and energy-saving grinding equipment, the LM vertical roller mill provides strong support for improving resource processing with its stable performance and advanced technical indicators.

River pebbles enter the center of the mill's grinding disc through air-locked feeding equipment. Under centrifugal force, they move to the periphery and enter the grinding roller track, where they are crushed by the extrusion, grinding, and shearing of the grinding rollers. Meanwhile, hot air is ejected at high speed from the air ring: coarse materials are blown back to the grinding disc for re-grinding, while suspended materials are dried. Fine powder is carried by the hot air into the classifier for grading—qualified fine powder is collected as finished products by dust collection equipment, and unqualified coarse powder falls back to the grinding disc for cyclic grinding, thus efficiently completing the entire operation.

Application of River Pebble Sand and Powder

The successful application of Liming Heavy Industry's river pebble pulverizing vertical mill technology in Xinjiang has provided a low-cost, high-performance solution for the local sand and powder processing industry, and promoted the green transformation of resource-based industries through technological innovation. We firmly believe that only by adhering to technological innovation and putting service at the core can we remain invincible in the fierce market competition and create lasting value for customers.
