Best practices for using hydraulic breakers
PP&E recently connected with Stephane Giroudon, general manager at Montabert, to discuss a number of areas related to breakers, including maintenance practices, new markets for the tools and more.
PP&E: Breakers are inevitably needed at a number of operations, but how and when are breakers best put to use in rock crushing and C&D recycling settings?
SG: In rock crushing and C&D recycling, hydraulic breakers are best used in reducing oversize material prior to feeding into a primary crusher to optimize the crusher feed rates.
PP&E: In a quarry setting, what impact are improved blasting techniques having on the use of breakers?
SG: Improved blasting techniques and hole tracking have decreased the amount of oversize that needs to be reduced. As a result, hydraulic breakers are now able to size the material for the primary crusher in a shorter time frame, increasing efficiency and productivity for quarry operators.
PP&E: What are some best maintenance practices that can be employed to prolong the life of breakers?
SG: Ensuring proper, constant greasing of the tool and bushing will greatly improve the life of the breaker. Regular inspections of the tool and bushing for wear and replacement of worn parts will also prevent premature failure. Operator training and preventive maintenance also play an important role in preventing misuse or missed service that can dramatically shorten the life of a breaker.
PP&E: What advantages are seen by producers who use breakers in direct tandem with their portable crushing plants?
SG: The use of hydraulic breakers for “pre-sizing” material for portable crushers allows for more consistent feed rates and less jams or clogs, which often results in costly downtime and repairs. Proper sizing of the material with the use of a hydraulic breaker also reduces wear on the portable plant.
PP&E: Are there any new possibilities or markets embracing breaker technologies these days?
SG: The expansion of metropolitan areas has created a need for demolition in areas where blasting is not an option. Hydraulic breakers are ideal for demolition applications and capable of demolishing thick concrete, foundations and buildings. Some site preparation companies are also recognizing the benefits of larger breaker models used for mass excavations.
