provide recycling solutions for applications that may require versatility. ConstructionWorld spoke to Fernando Abelho, Pilot Crushtec International’s Export Manager who explains how Rubble Master enables contractors to work smarter and achieve greater productivity by using the Rubble Master.

A belho says that Rubble Master is a range of mobile compact recycling machines of which the powerful impact crushers provide recycling solutions in versatile applications. “These reliable machines produce uniform cubical shaped aggregate from construction debris, natural rock and asphalt. It is ideal for use in urban layout as they possess noise protection, while transporting is easier as they are light and compact,” he says. “Comparative impact crushers with similar throughput can be anything up to 30- 40% larger physically,” Abelho says. Product philosophy Abelho says that one word summarises the philosophy behind the Rubble Master: simplification “On the face of it, Rubble Master’s developers attempt to keep it as basic as you can get. The machine has no complex settings. At the forefront there are few buttons and gauges. All the processing is done behind the scenes,” Abelho explains. Apart from simplicity, durability is vital. “The Rubble Master’s diesel-electronic system is more efficient than hydraulic systems. With hydraulic pumps you may lose up to 5% power every year. Electric motors maintain the same maximum capacity from day one to the end of life,” he says. “Apart from these,” says Abelho, “aspects such as longevity, ease of transport, productivity, usability and its compact nature are vital.” Working smarter The Rubble Master range is powered by a diesel engine and has a dust encapsulated genset to run its conveyors. “Fuel consumption is more efficient relative to the diesel hydraulic system that most mobile crushers use to drive the crusher,” says Abelho. “Further, the dust encapsulation on the genset is critical for any application where dust and fines

are present, for example coal crushing applications, as this minimises maintenance requirements and improves overall reliability. Operating the Rubble Master’s system is simple. “All the electronics are ‘behind the scenes’ so to speak and it takes the push of a few buttons to get the process started,” says Abelho. “Little technical training is needed to operate the units.” The range has a variety of options for dealing with different materials so as to improve on efficiencies. “It has a monitoring system (RM Go! Smart) that can be downloaded as an App to one’s phone which provides information such as fuel consumption, errors, warnings and operating hours. This can be used to help with the maintenance of the unit and monitoring production,” says Abelho. When crushing wetter material, the RM100Go! has an option for an Active Grid® on the feeder that allows for greater separation of wet material. The Rubble Master also has the option of a hanging screen to size the product that is crushed. “While a hanging screen to operate the crusher in a closed circuit has always been an option, the newer models can be operated in a closed circuit with the added functionality of an oversize belt from the hanging screen allowing it to pivot to a stockpile position for an additional oversize product,” says Abelho. An option that is especially useful when material is recycled is the Windsifter. “This enables the operator to produce cleaner material as a major challenge with recycled material is that it often contains many contaminants such as wood, paper and plastics. The Windsifter allows light contaminants to be removed upfront,” Abelho says. Raising the bar with trailblazing technologies “For its relative weight the Rubble Master is punching way above its weight class. It weighs about 28 tons and
