To further increase productivity and reliability, Komatsu has incorporated its patented HydrauMind hydraulic technology into its latest mobile crusher.
The system supplies the optimal amount of oil through load-sensing and pressure-compensated valves, which sense overloads and automatically slow the feed.
Equipped with a large-capacity KCJ4222 jaw crusher, the BR380JG-1 is powered by a 180-hp Komatsu SAA6D102E-2 engine and has a production output of 55 to 265 U.S. tph.
The BR380JG-1 offers numerous equipment feature:
Fully automatic discharge setting adjustment system that makes it easy to change the jaw discharge opening.
The vibrating grizzly feeder uses a two-step deck grizzly section to reduce clogging and evenly separates and feeds material into the jaw. In addition, an optional muck conveyor is available to further enhance feeding efficiency. The high-speed, large-capacity conveyor belt has a reverse feature to help remove jammed material.
NFLG jaw crushers
The NFLG jaw crusher sizes offered by Pennsylvania Crusher Corp. handle a wide range of materials at capacities ranging from 5 tph to 1,000 tph. Unlike ordinary jaw crushers , these models crush by compression applied in a straight line , with virtually no rubbing or grinding, the company says. This minimizes both fines and equipment wear.
In addition, the moving jaw of the Pennsylvania Crusher Corp. model is designed to be well balanced so that less power is needed to actuate the jaw. Most of the connected power is used to reduce the material. Because of this high mechanical efficiency, smaller motors may be used.
