Crusher’s hydrostatic system for different applications

By |  December 9, 2013

The Terex Finlay J-1170 is built around a 44-in. x 28-in. jaw crusher and has a track record in recycling, aggregate production and mining applications. The jaw chamber is available with an optional hydraulic release, which is ideal, Terex Finlay says, when crushing construction and demolition debris. The hydraulic release option has an automatic overload protection system to prevent damage from uncrushable items in the feed material.

In addition, the jaw chamber’s hydrostatic transmission offers operators reversible operation in the event of a blockage. The hydrostatic system provides variable chamber speed to suit given applications, Terex Finlay says. Also, the crusher features a hydraulic-assist┬áchamber closed side setting adjustment, and it can be changed in a matter of minutes.

The machine has a heavy-duty variable speed vibrating grizzly feeder with an integrated pre-screen, as well. The vibrating grizzly feeder ensures continuous choke feeding of the crushing chamber for optimal productivity, the company adds. Material from the pre-screen can be diverted to a stockpile via an on board bypass conveyor, or it can join crushed product on the main belt.

Also, the J-1170’s 12.55-cu.-yd. hopper has hydraulically folding sides and a hydraulic self-locking mechanism to provide efficient and faster machine setup and teardown times, according to Terex Finlay.
