High torque heavy duty gearboxes are essential for powering long-distance conveyors, grinding mills, and bulk material handling systems in mining, cement, and steel industries. These units deliver reliable performance under continuous high-load conditions where downtime is extremely costly.
Visão geral do produto
These gearboxes serve overland conveyors, ball mills, sag mills, and apron feeders. Core strengths include exceptional torque capacity, robust shock load handling, and the ability to operate continuously in dusty, high-temperature environments typical of mining and mineral processing plants.

Princípio de funcionamento
Power from the electric motor is transmitted through a high-speed pinion into multiple reduction stages of helical or bevel-helical gears. Each stage increases torque while reducing output speed. The final low-speed shaft connects directly to the conveyor pulley or mill pinion. A reinforced housing and oversized bearings absorb the heavy starting torques and shock loads common in these applications.
Principais vantagens
Handles peak starting torques of conveyors and mills without damage to gears or bearings.
Reinforced housing and optimized gear tooth profiles withstand sudden overloads from jammed material.
Designed for 24/7 operation with minimal maintenance in remote mining locations.
Precision ground gears achieve high efficiency, reducing energy consumption on long conveyors.
Foot, flange, and shaft-mounted options with torque arms simplify installation on existing structures.
Advanced sealing and forced lubrication systems allow longer periods between oil changes.
Artesanato em estrutura e materiais
Housings are fabricated from high-strength steel plate or heavy cast iron with internal ribbing for maximum rigidity. Gears are precision ground from case-hardened alloy steel. Large-diameter shafts and oversized spherical roller bearings handle combined radial and axial loads. Multiple labyrinth and lip seal stages provide excellent protection against abrasive dust.
Cenários típicos de aplicação
Transportadores terrestres: Transmits power to the head pulley of long-distance belts transporting ore or coal from mine to processing plant. High torque handles full load starts reliably.
Ball and SAG Mills: Provides the massive starting torque and continuous low-speed power required for grinding operations in mineral processing.
Apron Feeders: Delivers controlled high torque to heavy apron feeders handling large lumps of material at the primary crusher discharge.
Guia de Seleção
Calculate required output torque including starting torque and service factor. Determine exact ratio needed for desired belt or mill speed. Consider mounting position, available space, and ambient conditions. Evaluate thermal capacity for continuous operation and confirm adequate lubrication system for remote sites. Discuss pulley diameter, belt tension, and any future capacity increases with the engineering team.

Perguntas frequentes
Q: What service factor is recommended for conveyor applications with frequent starts?
A: A minimum service factor of 1.8 to 2.0 is advised for conveyors with frequent loaded starts to account for high starting torque.
Q: How is lubrication handled on remote mining sites?
A: Forced lubrication with oil coolers and condition monitoring is standard. Oil analysis programs help extend change intervals.
Q: Can these gearboxes be supplied with condition monitoring sensors?
A: Yes. Vibration, temperature, and oil condition sensors can be factory-fitted for integration with plant SCADA systems.
Q: What is the typical lead time for a high torque unit?
A: Standard configurations are available in 8 to 12 weeks. Fully custom designs with special ratios or cooling systems require 14 to 18 weeks.
Q: Are spare parts readily available for older models?
A: Yes. Critical components including gears, bearings, and seals are stocked for both current and legacy high torque series.
Estudos de Caso – Notas de Campo de Engenharia
Chile – Large copper mine in the Atacama Desert. A high torque gearbox was installed on a 6.2 km overland conveyor. After 22 months of continuous operation the maintenance team reported zero unplanned stops and confirmed excellent performance in extreme dust and temperature conditions.
Canadá – Gold processing plant in northern Ontario. The unit drives a large SAG mill. The operations manager noted smooth starting under full load and stable oil temperatures even during winter operation at -35 degrees C.
South Africa – Platinum mine near Rustenburg. Installed on a primary crusher apron feeder. Site records show reduced energy consumption compared with the previous supplier and successful completion of the first major service interval without gear or bearing issues.
