In this third chapter of a seven-part series on the characteristics of effective leadership, IQA member and Hanson Construction Materials manager Sarah Bellman discusses her experiences of building leadership credentials in the quarrying industry.
Choosing a mobile that outdoes the modelling
As Metso Outotec’s Australian distributor, Tutt Bryant Equipment is expected to provide knowledgeable support, a wide range, and quality service – a tall order for any business. But after a quick chat with Tutt’s staff, it becomes clear they have all that and more.
Schaeffler seals the deal with top of line sealed bearings
Bearing failures on mine sites occur most often due to contaminants, such as aggregates, iron ore, coal or any mining material penetrating the seal of the housing. This is aggravated by poor maintenance of the equipment, insufficient or excessive lubrication, and incorrect installation.
On a mine site, water is often used to wash down equipment, leaking through the bearings, turning dust into mud, and hindering performance on production lines.
Sealed spherical roller bearings, as Tony Tormey, BSC’s product manager for industrial bearings explains, are the “last line of defence” where bearings are used in dust-prone applications in mining, such as in conveyor pulleys or conveyors in cement mills.
“Bearings in harsh conditions like mining generally have three barriers, which is the housing, the grease and the seal on the bearing. You can also fill the cavity in the housing with grease, which will act as another barrier,” Tormey said. “But despite all that, water or dust can still penetrate the housing, and that’s where sealed spherical roller bearings provide an extra layer of protection to the bearing.”
Battery-powered screen joins decarbonisation challenge
Powerscreen, a manufacturer and provider of mobile crushing and screening equipment, has responded to the decarbonisation challenge by unveiling the concept Eco-Warrior battery-powered mobile screen.
Optimised vibrating screens boost family business
A third-generation family quarrying business is maintaining its commitment to quality across changing seasons through its decades-long preference for sophisticated and optimised vibrating screens and their screen media.

Upstream tech solves downstream wear and tear
How you drill and blast your aggregate can be vital to how it is processed and refined downstream. Steve Price, of Impact Drill & Blast, explains why a full rock-on-ground service can ensure an operation’s quarry products smoothly make the transition from the face to the gate.
Machines of best fit: OEM recommends vibrating screens
As the distinctive identities of many products in the crushing and screening sector give way to rationalisation over time, one OEM is staying dedicated to offering the aggregates industry the best of its screens and feeders – across five different brands. John Flynn explains.
