Rethinking the compact crusher

By |  May 15, 2018

A series of portable plants were in action at Rubble Master‘s Live Demo Days event at Winzinger‘s recycling yard in Franklinville, New Jersey, where the RM 120GO! impact crusher was introduced to the North American market.

A custom crushing solution for large asphalt paving contractors, road builders, demolition contractors and material producers, the RM 120GO! offers a production capacity of up to 385 tph without sacrificing mobility, Rubble Master says.

Featuring a 44-in. rotor and weighing just 90,000 pounds in a closed-circuit configuration, the RM 120GO! features the options and tonnage requirements to meet high-performance production demands without the weight and hassle, the company says.

“For years in mobile crushing, in order to get 44 in. of rotor, the machine needed to be huge. It just needed to be a monster,” says Geoffrey Faber, West territory manager at Rubble Master. “This machine is tailored to be a 44-in., high-production mobile compact crusher.”

Gerald Hanisch, founder and CEO of Rubble Master, agrees.

“We’ve always looked at the crushing industry differently,” Hanisch says. “When I turned my sights to the larger spectrum of machines, I was unimpressed with what I saw. I didn’t understand why a machine had to be over 100,000 pounds. To be honest, I didn’t like the way the table was set, so I flipped over the table.”

According to Faber, the RM 120GO! opens a new market for Rubble Master – the contractor requiring high-production volumes who does not want a 115,000-pound machine.

“Contractors tailored to the urban environment are simply not going to get a 115,000-pound machine on Wilshire Boulevard,” Faber says. “With this machine, that’s no problem. This machine is designed to be a full-sized, high-production impact crusher yet still tailored to the urbanized contractor.”

The RM 120GO! can be unloaded and set up for crushing in a closed-circuit configuration in less than 20 minutes without the need for special hand tools, the company adds. Like all Rubble Master impact crushers, the RM 120GO! features the company’s diesel-over-electric drive system.

“Anyone can set up one of these machines in less than 20 minutes,” Faber says. “Incredibly ergonomic, this machine is designed from cradle to grave with the contractor in mind. It’s designed to be operated by individuals who have zero crushing experience, [yet] within a matter of hours [they] can be remarkably successful.”

Other demoed equipment

While the North American debut of the RM 120GO! was the highlight of Live Demo Days, Rubble Master also showcased other crushing, screening and conveying equipment.

Scalping screens, including the RM HS3500M with a 9-ft. x 4-ft. screen deck screened construction and demolition waste. The RM HS5000M with a 12-ft. x 5-ft. screen deck, meanwhile, screened asphalt as the RM HS7500M with a 16-ft. x 5-ft. screen deck screened mulch.

“The scalping screen is pretty much a must-have for any contractor out there,” says René Wagner, inside sales manager and marketing coordinator at Rubble Master. “It’s a very versatile tool you can use in multiple applications. A contractor can use it as a standalone to screen out products.”

The HS5000M also pairs well with a portable crusher, Wagner adds.

“In combination with the crusher, it makes a ton of sense,” he says. “You can get rid of the fines in your feed material in case you have a lot of dirt in there, and you get a cleaner finished product. The better the product is that comes out at the end, the more value you have. If the material you put in is cleaner, the material that comes out is cleaner.”



At Live Demo Days, Rubble Master also demonstrated the RM MTS2010, a 65-ft. tracked stacking conveyor that operated in tandem with the RM 120GO! The RM 120GO! crushed concrete rubble up to 30 in. in diameter to produce a 1-in. finished product in a single pass. The unit was fed with a 30-ton excavator, and the finished product was stockpiled with the RM MTS2010.

“The [stacker] complements the crusher,” Wagner says. “Once it hits the end of the conveyor you need to move it, and there are three ways to do it.”

According to Wagner, contractors can either back up the crusher, utilize a wheel loader or pair the crusher with a stacker.

“Typically, contractors realize quickly after they purchase a crusher that they need something in addition to [the crusher],” Wagner says. “A [stacker] offers convenience. You need to move the material and get it out of your way. If you run a certain amount of hours every year or month, there’s a certain payoff. So do you pay a guy with a wheel loader or just make the payment on the stacker and put the fuel in there, which is close to nothing? It makes total sense for your crusher.”
