Gear Systems for the Mining Sector

It’s second-nature to Hardman to recommend ‘x-solution’ instead of ‘y-solution’ if we know it’s a better fit for your application, and we do this by having intricate knowledge of the gear systems outlined below and how they relate to the mining sector. Let’s go through a few of them:

Lubrication Pump Gear System

• For crushers, conveyors and screeners, this gear system ensures thorough lubrication of bearings and gears, while grinders benefit likewise for their mill bearings.
• This lubrication pump system is a must for conveyors to ensure smooth and continuous operation, and contributes to maintenance programs by ensuring longevity and efficiencies in crushing, grinding and screening equipment.

Reduction Gear System

• Reducing high-speed input from motors down to a lower speed with higher torque is where this reduction gear system is ideal for driving heavy-duty crushers, grinding mills and vibrating screens.
• Conveyors use this gear system to provide the required torque and adjustments in speed for driving the belts at optimal levels

Conveyor Drive Gear System

• It’s right there in the name – a gear system that drives conveyor belts to transport crushed or ground material to their next processing or storage area.
• Essential for screeners, to safeguard smooth material flow by conveyor belts between screening units, guaranteeing an uninterrupted screening process.

Feed Mechanism Gear System

• Vital for obvious reasons – crushers, grinders and screeners use this gear system to control the feed rate of mining materials into each of them, utilising variable speed drives and feeders with integrated gear mechanisms for precise control.
• Used in conveyors also to control the flow of material onto belts to facilitate consistent and controlled feeding.

Safety Mechanisms Gear System

• A non-negotiable for mining operations – safety devices such as emergency stops, automatic shutdown mechanisms and overload protection systems all deploy this type of gear system.
• Similarly, conveyors also integrate safety mechanisms to prevent dangerous incidents and promote constant safe operation under all conditions.

Hydraulic Gear System

• Used by hydraulic-driven crushers and mills to provide the force necessary for the crushing and grinding of materials, converting fluid power into mechanical motion.
• Can be used in specific vibrating and rotary screens to drive material separation mechanisms.
• Hydraulic-driven conveyor systems rely on this gear system’s precise control and movement

Pinion and Ring Gear System

• Large crushers and grinding mills deploy this gear arrangement regularly as it transmits torque to both crushing mechanisms and mill drums.
• Known to be used in heavy-duty conveyor systems for reliable power transmission.

Central Drive Gear System

• Smaller mills where space is a consideration will occasionally use this gear system where the mill drum needs to be rotated directly
• Direct-drive conveyor applications can use this system where advantageous.

Exciter Mechanism

• Screeners can use this mechanism which uses gears to convert rotational motion into linear or elliptical vibration, moving the screen deck to separate materials.
• Vibrating conveyors will occasionally deploy this mechanism to aid the materials’ movement.

Screening Media Tensioning Gear System

• A gear system that controls tension levels and maintains the wire cloth or synthetic panels on the screening decks

Incline Adjustment Gear System

• Screeners find this gear system advantageous, adjusting the screen deck’s angle for the ideal material flow and separation, whether it’s manually operated or automated.
• And unsurprisingly, it’s conveyor systems that make use of this system’s prime function of adjusting the incline of the belts to keep material transport and flow at an optimum.

Auxiliary Drive Gear System

• Ideal for maintenance procedures – grinding applications use this gear system to rotate the mil slowly or to position the mill drum for materials loading and unloading.
• Similarly, conveyors deploy this gear system in maintenance mode to move the belt slowly.

Control System Gear Components

• Screeners use this system to monitor and adjust screening operations, precisely controlling vibration frequency, amplitude and feed rates.
• Can be used to monitor and adjust conveyor operations, controlling speed and material flow.
