Kormann Rockster Recycler GmbH is an expert within the design and manufacture of mobile crusher for that lucrative processing of found materials and recycling of concrete, asphalt, and demolition boulders. As a result of customer demands, the company??s R1100D impact crusher noted for its robustness and crushing ratio associated with a material ?? was selected to become remodeled for quieter and much more fuel-efficient operation.
The brand new R1100DE machine uses an auto they are driving the crusher??s primary drum, while hydraulics provides other mechanical energy. The electrical motor??s high beginning torque causes it to be well suited for rotating the drum. Electrical energy is supplied with a generator driven at constant speed through the R1100DE??s diesel engine. Two pairs of tandem-mounted hydraulic pumps will also be driven through the engine. And since the engine runs at constant speed, all pumps have variable displacement to provide that energy needed through the load.
Parallel Electric hybrid drive
With the aim of enhancing fuel efficiency, the Rockster R&D team labored along with a Finnish component manufacturer to build up a parallel hybrid solution. Unlike diesel engines, electric motors supply full torque from the standing start within milliseconds, are designed for load changes effectively, and let an exact and steady crusher speed regardless of the burden demand. Permanent-magnet motors provide low-energy consumption, faster response, and greater energy density than conventional motor-generator sets.
The R1100DE mobile crusher uses four Parker Hannifin P1/PD Series pumps for hydraulic energy. Two operate right and left track drives, one works a vibrator, and something works a hydraulic-fan drive.
Peak loads are covered with batteries that temporarily store electrical power. Any load peaks are padded by condensers, which buffer energy and lower fuel consumption. The nearly put on-free electric motors reduce fuel consumption and maintenance costs. Ultimately, the R1100DE can conserve to 16,000 liters of diesel each year.
To combat the frequent load peaks and severe environment job conditions, Rockster made high demands around the materials. All electrical components are water cooled and adhere to the IP65 standard. They are equipped for use within mobile machines and superbly shielded from dust, grime, and water. Additionally, they're resistant against oscillations and wide temperature versions.
Hydraulics for energy and flexibility
The Rockster R1100DE is outfitted with variable-displacement piston pumps for that machine hydraulics and offer that pressure and flow needed through the load. This doesn't only save fuel, but additionally creates a continuously high material-handling rate, despite the diesel engine operating at relatively low speed.
With the choice to use four Parker P1045 variable-flow piston pumps with electronic control, Rockster engineers could integrate extremely fast and repeatable flow for that track drives, cooling fan, and conveyor devices.
The brand new hydraulic design uses four Parker P1045 pumps mounted together from two energy takeoffs (PTOs). All pumps are outfitted with Parker sequence valves in the outlet, supplying zero-flow capacity. A digital-control unit monitors pump pressure and instantly instructions pump displacement to complement that needed through the load.
The functions from the four pumps are the following:
One pump works the machine??s right track, plus among the conveyors.
The 2nd pump works the machine??s left track and the other conveyor.
The 3rd pump works a hydraulic-fan drive to cool down the.
The 4th pump provides flow to some vibrating unit that screens gemstones after they've been crushed.
Previous machine designs were operated by fixed-displacement pumps, necessitating the engine to operate at full speed to function the conveyors at high-speed. The variable-displacement axial-piston pumps, however, permit the engine to operate in a lower speed, which saves fuel and reduces noise.
