LYH138 Ultra-Fine Raymond Mill: Precision Grinding and Smart Installation in Jiangsu

Years change, Huazhang is renewed day by day, and the value of "manufacturing" to "intelligence" sets sail.

In January 2026, the winter morning light in the Yangtze River Delta penetrated the mist and shone on the modern factory area of Nantong Liyuanheng Machinery Co., Ltd. In the standardized heavy equipment delivery area, a majestic and exquisite craftsman wearing "LiYuanheng Red" LYH138 super large Raymond mill , is being placed smoothly on a special hydraulic axis transport vehicle by an intelligent traveling crane.

This marks the physical displacement of a piece of high-performance equipment, and also means the official start of the in-depth implementation of Nantong Li Yuanheng's "integration of equipment delivery and professional technical services" model - this LYH138 will drive to a high-end new materials technology park in Jiangsu and receive precision installation, commissioning and guidance services led by Li Yuanheng's senior engineer team, laying a solid foundation for the customer's industrial upgrade blueprint.

Chapter 1 The most important weapon of the country, the technical heritage and mission of LYH138

• A new benchmark for scale and performance: As a representative product of the 138 series, its grinding ring diameter, host power and system integration are among the best in the industry. When designing the table, the output (according to material hardness) can reach 8-25 tons , the finished product granularity can be found in D97=5μm to 45μm Flexible and stable adjustment of time meets the large-scale, continuous and high-quality production needs of Jiangsu customers.
• Core technology breakthroughs:

1. Layered grinding and multi-force field synergy technology: The innovative air flow and material flow field design in the grinding chamber enables the material to achieve efficient graded grinding under the combined action of centrifugal force, shear force, and extrusion force, with higher energy consumption than traditional models. Optimize more than 18% .
2. Intelligent temperature control and accuracy guarantee: Integrated multi-point temperature sensing and air volume adaptive system can effectively control the grinding temperature rise, protect the activity of heat-sensitive materials, and ensure product performance consistency.
3. Fully enclosed negative pressure production and pulse dust removal: The system adopts the ultimate sealing design and efficient back-end collection. The working environment is clean, and the dust emission is far better than the national ultra-low emission standard, which is in line with Jiangsu's strict requirements for green manufacturing.

This LYH138 carries the customer's strategic expectations of improving product competitiveness and expanding market share. It is also Li Yuanheng's solemn commitment to empower the real economy with cutting-edge equipment.

Chapter 2 From drawings to site, scientific and rigorous “pre-installation” escort

Delivery is only the beginning of service. In order to ensure that LYH138 achieves "seamless connection, accurate placement, and efficient production" at the customer's site, Li Yuanheng's project management process has been started as early as the middle stage of equipment manufacturing.

• Three-dimensional modeling and site pre-review: After signing the contract, Li Yuanheng's technical team used BIM technology to conduct a three-dimensional layout simulation of the entire set of equipment based on the preliminary factory data provided by the customer, identifying issues such as spatial interference, logistics channels, and load-bearing points in advance, and submitted the "Basic Layout Drawing", "Power Pipeline Interface Drawing" and "Installation Condition Confirmation List".
• Basic guidance and joint acceptance: The company dispatches preliminary engineers to the site to conduct technical briefings and provide guidance on key aspects such as concrete marking, location and levelness of embedded parts, and maintenance cycles; after the foundation is completed, both parties jointly accept the project to ensure delivery conditions.
• Component pre-assembly and modular transportation: A large number of pre-assembly and modular integration tests have been completed in the factory. The main machine, classifier, cyclone collector, pulse dust collector, fan and pipeline have been pre-numbered and matched before shipment to ensure that they are "matched" on site.

Chapter 3: Ingenuity in action, panoramic record of professional installation guidance

On the day the equipment arrived at the Jiangsu customer factory, a team of mechanical, electrical, and process engineers was led by the senior project manager of Li Yuanheng After-sales Service Department. 5-person special service team Arriving simultaneously, we started the precise installation and guidance work which lasted about 15 days.

The first stage: unpacking inspection and safety briefing

The service team, together with the personnel of the customer equipment department and the safety and environmental department, unpacked the boxes and checked them item by item according to the "Shipping List". Then the first on-site meeting was held to explain the installation safety procedures, daily plans and coordination interfaces, sign the "Safe Construction Agreement", and establish the principle of "safety first, quality first".

The second stage: precise positioning and leveling of the core host

The weight of the LYH138 main engine exceeds 50 tons. The engineer used a laser level and a frame level to direct the hoisting, and it took two days to complete the hoisting, preliminary leveling and fine leveling; the secondary grouting of the anchor bolts was strictly carried out in accordance with the process to ensure stable long-term operation.

The third stage: system integration and pipeline connection

The service team organized the hoisting and docking of the grader, large cyclone and dust collector according to the pre-installation number. The flanges were made of high-strength sealing materials; the electrical engineer simultaneously completed the main electrical cabinet placement, cable bridge laying and power/control wiring. The wire numbers were clearly marked and complied with GB standards.

The fourth stage: stand-alone debugging and linkage test run

1. No-load trial operation: Start the fans, classifiers, hosts and other equipment one by one, and use infrared thermometers, vibration detectors and noise meters to monitor and record key parameters.
2. Light-load debugging of belt materials: Insert a small amount of easily abrasive materials for "run-in", focus on checking the gas path sealing, dust removal effect and classification efficiency, and guide the customer to read the pressure/current meter and initially adjust the speed of the classifier.
3. Full-load process debugging and parameter optimization: Match the analyzer speed, air volume and feeding speed around the target product (such as heavy calcium carbonate D97 ≤ 10 μm), take samples for testing and draw a "parameter-particle size" curve to help customers lock in The best, most stable and most energy-saving craft points.

Stage 5: Systematic training and document delivery

• Theoretical courses: explain working principles, daily operation SOPs, common fault identification and maintenance points.
• Practical drills: Customer operators independently complete the startup, parameter fine-tuning, shutdown and emergency handling procedures under supervision.
• Data transfer: Complete documents such as "Operation and Maintenance Manual", "Electrical Schematic Diagram", "Spare Parts List" and "Debugging Report" are delivered and backed up electronically.

Chapter 4 Customer Testimonials and Value Sublimation

The customer's production director said at the completion acceptance meeting that Li Yuanheng engineers' professionalism and rigor run through the entire process of basic construction and debugging. In particular, debugging optimization not only produces qualified products, but also helps the team master the method of managing production through data.

After LYH138 is put into operation, the fineness is stable and the particle size distribution is concentrated; the energy consumption per unit of production capacity is reduced and the comprehensive cost is controlled; the fully enclosed dust-free environment improves operating conditions and enhances the company's ESG image.

Epilogue: Deepen trust with service, and create a better future with intelligence.

In the first month of 2026, this LYH138 shipped to Jiangsu and its accompanying in-depth installation guidance services illustrate Li Yuanheng's insistence on the three-in-one value delivery system of "products, technology, and services": from pre-installation planning, on-site construction to debugging optimization and knowledge transfer, it ensures that the equipment creates continuous, stable and efficient benefits at the customer site.

This trip to Jiangsu was both a technical expedition and an in-depth service development. It consolidated Li Yuanheng's position in the high-end powder equipment market in East China and established a strategic partnership with customers based on deep trust and common growth. Facing the future, Li Yuanheng will continue to focus on high-end equipment and full-cycle services, and work with partners to jointly promote China's intelligent manufacturing.
