5. Application Case of SRM1300-3 Vertical Roller Mill

A large metallurgical enterprise in Southeast Asia sought a high-efficiency grinding solution for iron ore processing, requiring stable performance, low energy consumption, and compliance with local environmental standards. After evaluating multiple options, the enterprise chose Mascot’s SRM1300-3 Vertical Roller Mill system.

The SRM1300-3 system, including the main mill and all auxiliary equipment (bucket elevator, belt scale, dust collector, etc.), was installed and commissioned within 45 days. Since operation, the system has maintained a stable processing capacity of 22t/h, with finished product granularity of 100um (meeting the enterprise’s requirements). The energy consumption per ton of ore is reduced by 35% compared to the previous ball mill system, and the dust emission meets the local environmental standards of ≤30mg/m³.

The enterprise reported that the SRM1300-3’s PLC intelligent control system simplifies operation, reducing labor costs by 20%, and the low maintenance requirement has cut maintenance costs by 15% annually. This case fully demonstrates the SRM1300-3’s reliability, efficiency, and cost-saving advantages in metallurgical applications, similar to successful VRM applications in phosphate and iron ore processing worldwide.

6. Frequently Asked Questions (FAQs)

Q1: What should I do if the SRM1300-3 vibrates excessively?

Causes: Unstable feeding, hard impurities, or uneven grinding roller wear. Solutions: Adjust feeding uniformity, remove impurities, or replace worn rollers.

Q2: Why is the output below the designed capacity?

Reasons: Insufficient grinding pressure, low hot air temperature, or high classifier speed. Solutions: Adjust hydraulic pressure, increase hot air temperature, or reduce classifier speed.

Q3: What is the service life of grinding rollers/table lining and how to extend it?

Service life: 8000-12000 hours (low-abrasion materials) or 4000-6000 hours (high-abrasion materials). Extend by controlling feed size (<30mm), maintaining stable material bed, and cleaning impurities regularly.
