Sandvik Jaw Crushers Features & Benefits

Foot

Bolt on feet allows the crusher to be positioned in different angles and lowered down onto a mobile chassis or a steel structure.

Nip angle

Very important regarding the performance of the crusher. Sandvik have a nip angle between 16-23º.

Labyrinth and lip seals to prevent ingress of dust as well as a rigid one piece solid bearing housing for maximum reliability.

Bearings

Heavy duty deflector plate

Important, takes the heavy impacts against the shaft and bearing that occur during crushing. Also helps to direct the material into the crushing chamber.


Gap

eW

idth

Symmetrical chamber.

Well dimensioned gape to width ratio

Feed opening dimensions are measured horizontally.

Steel shim plates.

To prevent impact on the jaw stock and frame and protect against wear in the event of the jaw plates becoming loose. This is a cost effective insurance .

Replaceable support strips are easy to change if the support becomes damaged. Without this capability the whole jaw stock would have to be removed and repaired

Replaceable support strips

Shim Plates can be used to improve the nip angle when operating at tight settings




Heavy duty (HD)Coarse Corrugated (CC)

Corrugated (C)Wide Teeth (WT)

Sharp Teeth (ST)

Designed to give high performance and low operating costsAll jaw plates are reversible



Coarse Corrugated (CC)• More wear resistant compared to C• Used for bigger CSS• Good top size control• Good fines “transport” in between the teeth.

Heavy Duty (HD)•For very abrasive materials•Not as good top size control•Could be combined with CC on the swing side



Sharp Toothed• Very good top size control.• Good fines “transport” in between teeth• Good gripping ability• Good reduction ratio• Highly recommended if the Ai is not too high

Corrugated (C)•Suitable for less abrasive materials•Good for small CSS•Good top size control•Good fines transport in between teeth



Wide Teeth (WT)•The same plate is used for both sides, less stock required•Good wear resistance•Good gripping ability


Sandvik Jaw Crushers Competitor comparison

Capacity

Nip Angle Low frame height with large gape indicates poor nip angle. Also will reduce weight and price

Speed Higher speeds--- lower capacity---finer discharge. Lower speeds---higher capacity---coarser discharge.

Motor capability Relates to the strength of the frame and swing-jaw assembly

Feed arrangements Gape needs to be dimensioned to accept largest blocks.

Feed size capability Lack of protection plate will encourage heavy feed chute with corresponding reduction in feed size capability.

Frame design Bolted/welded—weld position Welded frame distributes forces evenly throughout the frame. Bolted construction concentrates forces towards the friction joint

Box section castings Stronger than open castings

Alignment of toggle plate Toggle plate has to be aligned to direct the forces evenly through to the rear support

Wear protection Sacrificial plates behind jawplates Lack of protection will eventually lead to expensive repairs to frame and swing-jaw

Replaceable support strips Lack of protection will eventually lead to expensive repairs to frame and swing-jaw

Bearing housing design Solid ring v split housing/plummer block Solid ring will prevent cracking of bearing inner race through stress concentration
