Insun presents the Used SINOMA TRM32.3 Vertical Roller Mill — a robust solution engineered for raw meal grinding, cement clinker grinding, and high efficiency slag grinding. Designed to deliver reliable performance at industrial scale, this vertical roller mill combines proven SINOMA engineering with optimized energy consumption and operational flexibility. With a rated capacity of 150 t/h and a powerful 1800 kW AC drive, the TRM32.3 is suited to modern cement plants and grinding circuits seeking consistent product quality, reduced operational costs, and streamlined maintenance.

Overview and key features

The Used SINOMA TRM32.3 Vertical Roller Mill is a compact, integrated grinding unit specifically tailored for raw meal grinding, cement clinker grinding, and high efficiency slag grinding. Its vertical roller mill configuration enables high throughput while maintaining tight particle size distribution control. Core mechanical components, including the grinding table, rollers, hydraulic system, and separator, have been designed for longevity and serviceability. The unit's 150 t/h capacity aligns with medium- to large-scale production needs, enabling plants to meet output targets with fewer parallel lines and lower footprint requirements.

Performance advantages

At the heart of the TRM32.3’s performance is the vertical roller mill’s inherent energy efficiency. Compared with traditional ball mills, the vertical roller mill reduces energy consumption per ton of material ground, which directly impacts operating costs. The 1800 kW AC drive provides stable power delivery for continuous raw meal grinding and cement clinker grinding operations, while delivering the torque necessary for challenging high efficiency slag grinding tasks. The mill’s hydraulic system ensures consistent grinding pressure and automatic compensation for wear, maintaining stable production and product fineness across long campaigns.

Product quality and process control

Product quality for raw meal grinding and cement clinker grinding is critical to downstream kiln performance and final cement properties. The TRM32.3’s integrated separator allows precise control of particle size distribution, enabling operators to target specific Blaine or residue metrics for clinker grinding and to ensure homogeneity for raw meal grinding. For high efficiency slag grinding, the separator adjustments and classifier optimization minimize over-grinding, improving specific surface area control and preserving energy efficiency. Advanced instrumentation and process control options are available to monitor differential pressure, separator speed, airflow, and temperature, ensuring consistent quality and enabling rapid feedback adjustments.

Applications and flexibility

The Used SINOMA TRM32.3 Vertical Roller Mill is versatile across cement plant applications. For raw meal grinding, the mill efficiently processes blended limestone, clay, and additives to produce kiln feed with uniform chemistry and particle-size distribution. In cement clinker grinding applications, the vertical roller mill reduces dependence on multi-stage ball mill circuits, offering a more compact and efficient alternative that can be retrofitted into existing plants. For high efficiency slag grinding, the TRM32.3 handles granulated blast furnace slag and other industrial by-products, producing high-quality ground slag suitable for blended cements and specialty formulations. This versatility allows plants to optimize their raw mix and product portfolio, reducing clinker factor and improving sustainability metrics.

Energy efficiency and sustainability

Energy efficiency is a major driver behind adopting vertical roller mill technology. The TRM32.3 minimizes specific power consumption through a combination of efficient grinding mechanics, effective classification, and reduced internal recirculation. The 1800 kW AC drive is optimized to deliver required grinding energy precisely, while modern control systems further reduce unnecessary power peaks and idling. Operational energy savings translate into lower CO2 emissions per ton of material processed, supporting sustainability goals and regulatory compliance. Additionally, the mill’s compatibility with variable fuel and material inputs makes it well-suited for plants transitioning to alternative raw materials or co-processing wastes, enhancing circular economy initiatives.

Maintenance, wear management, and lifecycle benefits

Insun understands the cost pressures associated with mill maintenance and longevity. The TRM32.3 was built with wear-resistant materials for rollers and table liners, and the vertical roller mill layout facilitates quick access to wear parts and hydraulic components. Predictive maintenance strategies, enabled by monitoring systems, allow operators to plan interventions based on condition rather than fixed schedules, reducing downtime and spare part inventories. When managed correctly, the lifecycle costs of a vertical roller mill compare favorably to traditional grinding systems, delivering sustained returns on investment through reduced energy consumption, lower media usage, and simplified material handling.

Installation and retrofit potential

A significant advantage of the Used SINOMA TRM32.3 Vertical Roller Mill is its retrofit potential. Plants seeking to upgrade legacy ball mill circuits or to increase capacity with minimal civil works can integrate the TRM32.3 with existing classifiers, baghouses, and material handling systems. Insun can advise on mechanical, electrical, and piping interfaces, as well as on control system integration to ensure smooth commissioning and ramp-up. For green-field projects, the mill’s compact layout and straightforward maintenance access reduce plant footprint and construction complexity, enabling faster project delivery.

Operational safety and compliance

Safety is a priority in any grinding installation. The TRM32.3 includes safeguards for overpressure, over-speed, and hydraulic system faults, along with access platforms and lockout provisions to support safe maintenance practices. Emissions control options, including high-efficiency dust collectors and integrated sealing solutions, ensure compliance with environmental standards and minimize fugitive dust emissions associated with raw meal grinding, cement clinker grinding, and high efficiency slag grinding operations.
