Austria-based crushing and recycling equipment maker Rubble Master HMH GmbH (RM) reports that its Argentina dealer Covema S.A.C.I.F. has helped place one of its machines into a high-volume, dual-purpose application.
An RM 100GO! model crusher has been on the job four years for a Covema customer who has been using it to crush both concrete and steel mill slag in a "highly efficient and environmentally friendly manner.”
The RM 100GO! has throughput capacity of 150 tons per hour and can crush both concrete and steel slag into either 0-to-500 millimeter fractions or to 0-to-30 mm pieces (either 19.5 inches maximum or 1.2 inches maximum).
RM says the RM 100GO! in Argentina typically operates for eight hours a day.
“The customer, an expert in the use and integration of recycled materials in road construction in Argentina, crushes concrete in order to reuse it for the production of new concrete,” RM says.
The slag, meanwhile, is crushed for road construction or recycled for the production of new steel. RM says 100 percent of the material introduced into the crusher has a recycling end market.
“It was particularly important to the customer to acquire a crusher that is suitable for a wide range of applications," the companies say.
Steel mill slag consists of mineral components and other elements that are removed from the ore and other materials used during the melting process. RM says slag usually contains iron that is dense enough to cause damage in some crushing chambers “if the wrong crusher is selected.”
The RM 100GO! features the RM Release System, an impactor opening installed to remove blockages in the impactor.
The company says larger pieces of iron-intensive material should still be sorted out or precrushed before feeding, as iron parts that are too big can cause damage to the crusher despite the release system.
