Longer jaw length to provide increased crushing area, steeper nip angle and increased capacity. Curved jaw dies to provide nonchoking crushing action, reversible for increased wear. Rugged frame with heavyribbed steel plate construction at stress points, stress relieved by heat treating before machining. Inside contact surfaces are fully machined.
The right jaw design can make a big difference. Columbia Steel offers more jaw crusher plate styles than any manufacturer in the industry. As viewed from the side, we offer straight, curved and straight with curved end jaw plates. Selection depends on nip angle needed for .
Its large feed opening and forced feeding action of Jaw Crusher from inward and downward eccentric movement of the swing jaw gives an increased capacity. Longer crusher jaws, a nonchoking crushing action design, and a larger eccentric throw results in a reduction in nip angle, and greater ratio of reduction in Jaw Crusher.
Jaw Crushers 6 A few of the special features are highlighted below • Curved scientifically proportioned jaw faces, which offer the following advantages: • No choking or packing • High capacities and low power consumption • Finer settings • Economy of operation and maintenance • Angle of nip progressively decreases as material proceeds
An optimized nip angle ensures that the material progresses smoothly down through the crushing chamber to enable high reduction, productivity and superb utilization of jaw plates It is not just a large nominal feed opening that is necessary †"the feed acceptance capability depends on a feed opening which is effective and active

Sep 23, 2015· KPIJCI and Astec Mobile Screens has expanded its Vanguard product line with the new, more compact 2056 Vanguard Jaw in efforts to meet every producer's operational needs. The 2056 Vanguard Jaw Crusher features a 20" by 56" jaw crusher that is ideal for sand and gravel applications, and also excels in recycled concrete and mining ...
Feb 12, 2008· Jaw Crusher Nip Angle The nip angle describes the angle the stationary jaw plate and the pitman make with each other. The exact value of this angle isn't quoted or even determinable due to curvature in the jaws themselves but what is important is how wide vs. narrow it is.
the nip angle when the crusher feed size is 10 cm, 4. the coefficient of friction between roll and gypsum particles. At a nip angle of 30°, an approximate relation between peripheral speed ν P (m/min), diameter of rolls D (cm) and sieve size d (cm) through which 80% of ore passes is given by the relation
Jaws longer than conventional crusher jaws permit a reduction in angle of nip, providing a more positive bite and fewer pinchedout rocks; Produces high production tonnage (up to 982 tph) and high reduction ratios while maintaining the same discharge opening size; Frame rigidity maintains bearing and shaft alignment and prevents costly failures
Jaw crushers process medium to hard quarry rock or other materials by compressing it between the fixed jaw and the swing jaw. The swing jaw being the moving part is attached to a rotating eccentric shaft. The fixed jaw is an integral part of the crusher frame. Both jaws are fitted with manganese jaw liners that can be replaced or reversed when worn.
The 2056 Pioneer Jaw Crusher is a newlydesigned, more compact model that features a 20" by 56" jaw crusher that is ideal for all crushing applications. The small gap provides an excellent nip angle at a tight closedsidesetting, making it a perfect fit for applications where material is minus16", according to Tim Harms, product manager for KolbergPioneer.
Aggresive Nip Angle. The sharp angle allows the jaw to consistently grab and process material for highlevel efficiency throughout the entire life of the die. Hydraulic Wedge Adjustment. Hydraulic wedge adjustment capability gives operators easy access to closed side settings. HeavyDuty Frame. Fullyfabricated base frame for strength and longevity.
The Grizzly King Jaw Crusher is heavier and stronger than most jaw crushers on the market. Its deep crushing chamber means less rock slippage, optimum nip angle, positive bite and fewer pinched out .
Iron Giant™ Series jaw crushers provide superior value in all operating conditions. To optimize performance, the Iron GiantTM jaws are designed with a long crushing chamber and shallow nip angles. These longer chambers provide both high volume crushing and .
Roll Crushers. It is generally considered that Roll Crushers are specially adapted for intermediate crushing, taking a product from rock breakers with a maximum diameter of from ¾ inch to 1½ inches, and reducing it to a size passing through a screen of 12 or 16 meshes to the square inch. Finer crushing, however, is often carried out.
On top of great performance, a good nip angle also reduces wear on the jaw dies and that has a direct impact on operating costs. High production and reduction: Jaw crushers are well known for the aggressive motion of the pitman and long stroke in the bottom of the cavity. This boosts the capacity as well as the reduction ratio, resulting in high production and better endproduct gradation.
Sandvik jaw crushers are of the singletoggle type with advanced features for optimized performance, easy maintenance, long life and a low cost per ton. These crushers feature a deep, symmetrical crushing chamber, easy settings adjustment, a large feed opening for its size, and an ideal nip angle that offers smooth material flow and high ...
All Sandvik jaw crushers are of the singletoggle type with a deep, symmetrical crushing chamber and easy setting adjustment. Each model has a large feed opening for its size and an ideal nip angle, giving smooth material flow, high reduction efficiency and high capacity.
