Insun presents the Used HRM3400 Raw Meal Vertical Roller Mill — a high-performance solution for raw meal grinding in cement production. Designed for efficiency and reliability, this 4 rollers RRM3400 unit delivers a 200t/h cement equipment capacity with robust 1800Kw AC motor and precision gearbox grinding equipment, offering operators a cost-effective and high-throughput alternative for modern plants.

Product Overview and Core Features

The Insun Used HRM3400 Raw Meal Vertical Roller Mill is engineered for continuous raw meal grinding with an emphasis on energy efficiency, stable operation, and ease of maintenance. As a vertical roller mill solution, this unit integrates a proven grinding bed concept with four rollers arranged to optimize pressure distribution and wear balance. The 4 rollers RRM3400 configuration ensures consistent grinding performance across varied raw materials and feed gradations, making the unit versatile for diverse cement industry requirements.

Key features include:

- Robust 1800Kw AC motor matched to a precision gearbox grinding equipment system for reliable torque transfer and minimized downtime.

- Four rollers RRM3400 setup that improves grinding efficiency and extends service life through balanced loading and optimized hydraulic control.

- Capacity rated at 200t/h cement equipment output for raw meal grinding, enabling substantial throughput for small and medium-sized cement plants or retrofit projects.

- Pre-owned HRM3400 unit refurbished to Insun standards, with inspected mechanical components, replaced wear parts, and verified hydraulic and control systems for safe, long-term operation.

- Compact vertical roller mill footprint that reduces civil and structural costs while allowing straightforward integration into existing process lines.

Applications and Operational Benefits

This Used HRM3400 Raw Meal Vertical Roller Mill is specifically tailored for raw meal grinding in cement production, but its robust design also supports processing of other minerals and raw mixes. The machine excels in scenarios requiring consistent particle size distribution and stable system operation. Typical applications include:

- Raw meal preparation for rotary kilns in cement plants using limestone, clay, and supplementary raw materials.

- Retrofit and capacity expansion projects where 200t/h cement equipment performance delivers meaningful throughput gains without full plant rebuilds.

- Replacement of outdated grinding systems where adoption of vertical roller mill technology reduces energy consumption and simplifies plant layout.

Operational advantages of this vertical roller mill configuration include:

- Reduced specific energy consumption due to efficient grinding bed dynamics and the use of large-diameter rollers that promote effective compression grinding.

- Enhanced process stability with improved flowability of raw meal and a consistent product fineness meeting kiln feed specifications.

- Lower maintenance costs compared with conventional ball mill circuits, owing to fewer rotating parts and easier access to wear components.

- Rapid start-up and flexible load response enabled by the AC motor and gearbox grinding equipment arrangement.

Innovation and Technical Advantages

Insun’s refurbishment and configuration of the Used HRM3400 emphasize technical enhancements that maximize the life cycle value of the vertical roller mill. Key innovations and technical advantages include:

- Precision gearbox grinding equipment adaptation: the gearbox coupling and gear profile are matched to the 1800Kw AC motor to ensure smooth torque delivery, minimizing shock loads and gear wear while improving reliability under high-capacity raw meal grinding.

- Hydraulic loading optimization for the 4 rollers RRM3400 design: Insun reconfigures hydraulic circuits to maintain even roller pressure, ensuring balanced wear and improved grinding efficiency across the roller assembly.

- Wear part management: rollers, grinding table segments, and protective liners are inspected and replaced where necessary to restore optimal contact geometry for efficient raw meal grinding and to maintain 200t/h cement equipment throughput.

- Control and instrumentation upgrades: modernized control modules enhance process monitoring, allow finer control of separator speed and air flow, and provide diagnostic capabilities to minimize unscheduled stops.

- Thermal and vibration diagnostics applied during refurbishment to identify and rectify potential failure points, delivering a reliable vertical roller mill ready to operate in demanding production environments.

Performance and Reliability

Insun’s Used HRM3400 has been validated to sustain continuous raw meal grinding at up to 200t/h cement equipment capacity when installed and commissioned according to recommended procedures. The vertical roller mill’s design minimizes variability in product fineness and reduces reprocessing needs, which contributes directly to kiln stability and fuel efficiency downstream. The combination of a powerful 1800Kw AC motor and robust gearbox grinding equipment supports long-term load-bearing performance, while the 4 rollers RRM3400 layout reduces peak stresses and distributes wear more evenly across components.

Maintenance and Lifecycle Support

Insun provides comprehensive lifecycle support for the Used HRM3400 Raw Meal Vertical Roller Mill. Services include:

- Full mechanical inspection and certified refurbishment of main pinions, bearings, rollers, and grinding table sections.

- Reconditioning or replacement of gearbox grinding equipment components and verification of motor coupling alignments.

- Hydraulic system overhaul and recalibration to ensure precise roller loading and reliable operation.

- Spare parts kits tailored to the 4 rollers RRM3400 configuration and a recommended preventive maintenance schedule to minimize downtime.

- On-site commissioning support, operator training, and remote assistance to ensure optimal integration with existing process controls and achievement of target 200t/h cement equipment output.

Economic and Environmental Considerations

Choosing a used, refurbished vertical roller mill like the HRM3400 provides a cost-effective path to higher throughput without the capital outlay of new equipment. Operational energy savings from modernized raw meal grinding technology can deliver rapid payback through reduced power consumption and lower maintenance overhead. Additionally, improved grinding efficiency and tighter product control reduce kiln feed variability, which can decrease clinker rejection and lower fuel consumption—deliverables that align with environmental and sustainability objectives.
