NGC MPG Series Roller Press Gearbox Introduction

The MPG Series Roller Press Gearbox, a high-performance heavy-duty transmission product independently developed by Nanjing High Accurate Gear (NGC), is exclusively engineered for the extreme operating conditions of roller presses in building materials, mining, and cement industries. Integrating NGC’s cutting-edge planetary gear technology and rich experience in bulk material processing equipment matching, this series is designed to withstand high pressure, heavy load, and impact loads, delivering reliable power transmission for roller press systems.

The core structure adopts a combined planetary and parallel-axis design, optimized through advanced finite element analysis (FEA) to enhance overall rigidity and load-bearing capacity. The gear system features precision ground hard tooth surfaces, fully compliant with ISO, AGMA, and DIN international standards, paired with specialized gear profile and lead modification technology. This ensures uniform load distribution across gear teeth, effectively resisting wear, pitting, and gluing, even under long-term continuous operation with high torque and alternating loads.

Targeted for roller press working conditions, the MPG Series is equipped with a reinforced housing made of high-strength cast iron, which effectively absorbs vibration and reduces structural deformation. A proprietary forced lubrication system with a high-efficiency cooler ensures stable oil temperature control, preventing overheating caused by heavy-load operation. The multi-layer sealing structure, combined with high-temperature and wear-resistant sealing materials, reliably prevents oil leakage and blocks dust, gravel, and other contaminants from entering the internal components.

The MPG Series covers a wide range of technical parameters, with power capacity from 160kW to 1250kW, speed ratios ranging from 15 to 40, and maximum output torque up to 200,000N·m, perfectly matching various roller press models and production capacity requirements. It is widely applied in cement clinker grinding, ore crushing, and building materials processing, providing core power transmission for roller presses to achieve efficient material compaction and grinding. Backed by NGC’s strict quality control and professional after-sales service, the MPG Series offers excellent durability, low maintenance costs, and stable operation, becoming a trusted choice for heavy-duty roller press applications.
