New pump technology leads to increased productivity

New pump technology is increasing flow rates, reaching greater heads and improving solids handling. ABE looks at the benefits for quarries. Managing drainage is an essential task in many European quarries as operators try to maximise reserves by extending below groundwater or coping with natural springs in the formation. These units not only allow for drier working conditions but also protect expensive equipment, so performance and reliability are key assets.

Automation reduces health and safety risk

Reducing human interaction with machinery through greater automation is helping to deliver improved safety for quarry operators. Long gone are the days of breaking, loading and hauling rock by hand in quarries and as a result the safety of quarry workers has improved significantly. In recent years the safety has improved exponentially as greater automation has further distanced workers from the machines.

Rigid trucks still favoured in quarries

Quarry operators with a long-term outlook still consider rigid dump trucks to be the most cost effective solution for hauling. Rigid dump trucks are frequently called the ultimate hauling machine but there are lots of different applications and whether it lives up to this accolade depends on how the customer uses the machine," said Caterpillar quarry and construction truck application specialist Dave Ellington. Cat is able to offer both ADTs and RDTs so is less biased than some manufacturers on what is best

Technology investment saves Vietnamese quarry

Investment in new drilling rigs and breakers has helped one Vietnamese quarry avoid closure. ABE reports. Gaining permission to extract rock by blasting is getting more and more challenging and the situation is no different in Vietnam. The government has applied a blanket ban on blasting in any quarry close to its cities, but there is still a growing demand for aggregates in these urban areas. The Bien Hoa Building Materials Production and Construction Company (BBCC) quarry is located 32km east of Ho Chi Mi

Tyre maintenance result in longer life

Maintaining tyres is an essential part of minimising operating costs as well as improving machine service life. The importance of tyre maintenance to maximise service life was put under the spotlight a few years ago with the global shortage of earthmover tyres. Now with more production and the economic slowdown, the shortage may be over but the need to reduce costs remains.

Portuguese marble in demand

While demand for construction aggregates has been affected by the global recession, the call for marble appears to be unabated. Claire Symes visited a Portuguese marble quarry to find out more. Some of Europe's most prestigious hotels, museums, churches and piazzas owe some of their magnificence to the marble that lines the floors and walls of these structures. And it is demand for these materials for contemporary construction that is helping to maintain this market at a time when there is a slowdown in the

GPS technology improves rig performance

Advances in technology are helping to deliver both improved hole straightness and BLAST detonations for better fragmentation. No matter how carefully the load and haul functions and crushing and screening processes have been designed, if the feed stock does not match the design, any efficiencies are lost. Improvements in drilling techniques and blasting technology are helping to deliver benefits that mean the actual blast matches the design more closely than ever before.
