Introduction

In cement, metallurgy, power and other industries, vertical mill (vertical roller mill) as the core equipment of material grinding has become the "heart" of modern industrial grinding process with its high efficiency, energy saving and stable operation. The grinding roller and grinding table, as the core components of the vertical mill, directly determine the grinding efficiency, energy consumption level and production stability of the equipment. How to extend its service life and reduce operation and maintenance costs through technological innovation and scientific maintenance? This article provides you with an in-depth analysis.

一、Grinding roller and grinding table: the "golden partner" for efficient operation of vertical mill

1. Core role

Grinding roller and grinding table are the core force-bearing components of the vertical mill grinding process, and undertake the key tasks of material crushing, crushing and grinding. The matching accuracy, material properties and surface morphology of the two directly affect the grinding efficiency and finished product quality.

• High energy-efficient grinding: The optimized design of the grinding roller surface and the grinding table groove can significantly increase the material crushing area and reduce unit energy consumption.

• Stability guarantee: The reasonable selection of wear-resistant materials can reduce the frequency of downtime and maintenance and ensure continuous production.

2. Technological breakthroughs

With the advancement of material science and manufacturing technology, the new generation of grinding rollers and grinding tables have achieved performance leaps through the following technologies:

• Composite surfacing technology: The life of the surface wear-resistant layer is increased by 30%-50%, reducing the replacement cost.

• Dynamic simulation design: AI-based simulation of the pressure distribution of the grinding roller, optimizing the structural stress and extending the life of the components.

• Modular design: Supports rapid replacement, reduces downtime, and improves capacity utilization.

二、Common problems and solutions for grinding rollers and grinding tables

1. Uneven wear

• Phenomenon: Abnormal wear on the edge of the grinding table or the end of the grinding roller leads to a decrease in grinding efficiency.

• Countermeasures: Use laser cladding repair technology to restore the geometric dimensions of the components; optimize the pressure distribution of the hydraulic system.

2. Surface cracks

• Phenomenon: Long-term high-load operation leads to the expansion of microscopic cracks, threatening the safety of the equipment.

• Countermeasures: Introduce an online monitoring system to track the wear status in real time and provide early warning maintenance.

3. Rising energy consumption

• Phenomenon: Unit power consumption increases and production capacity decreases.

• Countermeasures: Restore the original design parameters through roller surface regeneration technology to reduce friction resistance.

三、Scientific maintenance: the key to extending life, reducing costs and increasing efficiency

1. Preventive maintenance strategy

• Regular inspection: Conduct roller and disc thickness, hardness and morphology inspections every quarter to establish a wear database.

• Lubrication optimization: Use high-temperature and pressure-resistant special grease to reduce material fatigue caused by friction heat.

2. New trend of intelligent operation and maintenance

• IoT remote monitoring: Collect vibration and temperature data in real time through sensors to predict failure risks.

• Digital twin technology: Build a virtual mill model, simulate working condition changes, and optimize maintenance cycles.
