The left figures refer to fines removed from feed and the right refers to fines included in the feed. The Sandvik jawcrusher line is designed for the motor sizes listed in RPM and technical specifications. This means that for harder materials, the crusher will have to be operated at larger settings to avoid overload of drive and/or motor. Using oversized motors will lead to radically shorter crusher life and various mechanical problems. Warranty will not cover this! Capacity figures apply for clean, friable and dry granite with a bulk density of 1.6 t/m³ (100 lbs./cu.ft.) or compact density 2.65 g/cm³. Sandvik Construction

Sandvik Jaw Crushers Capacity Factors affecting CSS Stroke Width of chamber Feed size Toughness Bulk density Clay/Humidity 16 Sandvik Construction

Sandvik Jaw Crushers Throughput Factors reducing Lack of feed. Bridging/loader bucket dimensions. Poor nip angle. Load and haul reliability. 17 Sandvik Construction

Sandvik Jaw Crushers Features & Benefits Nip angle Bearings 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. Foot Bolt on feet allows the crusher to be positioned in different angles and lowered down onto a mobile chassis or a steel structure.

Sandvik Jaw Crushers Features & Benefits 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 . Shim Plates can be used to improve the nip angle when operating at tight settings 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 25 Tip: Excavator bucket matching the size of the jaw crusher Sandvik Construction

Sandvik Jaw Crushers Competitor comparison Capacity Nip Angle   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 Bearing housing design Solid ring v split housing/plummer block Solid ring will prevent cracking of bearing inner race through stress concentration  Welcome to Sandvik Construction
