Hardman Gearboxes for the Mining Sector

In each gearbox design and production lies an inherent strength that sees it suited to specific mining applications, and working together, Hardman will match the gearbox solution to where it’s most needed in your mining operations.

Here’s where our range of gearboxes is best suited in mining applications:

Planetary Gearboxes

• Crushers. Grinders and Screeners benefit from this gearbox’s high torque density, compact design, handling of heavy loads and high-impact conditions.
• Heavy-duty conveyors suit the high torque handling of a planetary gearbox, but especially the compact size for space-constrained installations.
• They are suitable for ball mills and vertical roller mills in grinding applications
• Planetary gearboxes are used in some rotary screens and other specialised screening equipment

Helical Gearboxes

• Crushers benefit from this gearbox’s ability to handle high radial loads, plus its smooth and quiet operation. Suits both primary and secondary crushing applications
• Screeners can use helical gearboxes for vibrating screens and other screening equipment
• Long conveyor systems usually favour these gearboxes due to their high efficiency and durability

Bevel-Helical Gearboxes

• Right-angle output and strong load capacity is what this gearbox does best, which suits grinders, screeners and crushers
• Crushers that require angular alignment regularly use this gearbox
• Grinders use them for SAG mills, ball mills and other large grinding mills
• And screeners find this gearbox ideal where space constraints and some types of vibrating screens require a right-angle gearbox

Inline / Helical Gearboxes

• You might also know them as parallel shaft gearboxes
• But whatever term you prefer, one thing that’s certain is that their good thermal capacity, robust design, high torque output and high-load handling sees them as the preferred gearbox for several applications
• Crushers, grinders and screeners requiring parallel alignment benefit from this gearbox solution
• Grinding mills where space constraints and parallel alignment are necessary favour this gearbox

Worm Gearboxes

• This gearbox provides a really specific solution – it’s compact design and low-speed output are perfect for slow and precise movement
• Ideal for both Screeners and Crushers where shock absorption and high reduction ratios are advantageous

Cycloidal Gearboxes

• Not as well-known as other gearboxes, but they come into their own for screening systems that require a high-shock load capacity and simultaneously high precision

• With very high reduction ratios (often significantly higher than other gear systems), compact design and their ability to provide high positioning accuracy and low backlash, they are ideal for conveyors and materials handling.

Cylindrical Gearboxes

• A cost-effective gearbox of simple construction and straight-forward design with a high-load capacity
• Crushing, conveyor and grinding applications make the best use of this gearbox 

Multistage Gearboxes

• Grinders are often the best choice for this gearbox, achieving high-reduction ratios, high torque and optimal power transmission.

• Large grinding mills (SAG mills and ball mills) use this gearbox normally, as multiple reduction stages are required

Custom Gearboxes

• And let’s not forget those situations where a tailored solution for specialised equipment is required.

• Whether it’s our build-to-print capability or a design collaboration you need assistance with, we can meet the specific requirements of your crushing, screening, grinding and conveyor systems.
