Stone crushers for primary crushing stage
Stone crushers are ideal for stationary, skid-mounted, or portable and mobile primary crushing applications.
Compare the increased production, reliability, reduced operating costs and flexibility of a NFLG Jaw. Its large feed opening, and force-feeding
action from the inward and downward eccentric movement of the swing jaw, means increased capacity. Longer, curved jaw dies, a non-choking crushing action design, and a larger eccentric throw result in a reduction in nip angle, a more positive bite, and greater ratio of reduction.
A NFLG Jaw can have a smaller discharge setting, allowing for a higher degree of flexibility with related equipment . Positive setting adjustment is easy.
Reliability is the hallmark of a NFLG Jaw, featuring rugged ribbed frame construction, a one piece cast pitman, heavy duty rock ribs that protect the pitman, a huge oversized heat-treated shaft forged of special alloy, and extra large, premium quality tapered roller bearings that absorb and withstand radial and thrust shock loads. Finite element analysis techniques assure sound design and maximum strength at all stress points for trouble-free crusher operation.
The NFLG jaw is quality engineered for simplicity, easy access, low maintenance and includes reversible jaw dies for increased wear. An optional lube system is also available.
NFLG Large Model Heavy-Duty Stone crushers
When you need a truly massive jaw, NFLG’s range of large model jaws includes a 5062, 4248, 3650 and 3048 to suit your particular heavy-duty,
high volume crushing application.
These jaws offer maximum capacity, and are heavier, stronger, and more reliable than competitive jaws. Hydraulics save countless hours. Tension rod air springs maintain pre-set loading regardless of setting, so you can adjust under load. Wedge effect holds toggle bearing in on pitman and block for easy bolt-in removal and replacement.
