1.Jaw Crusher Wear Parts Working Principle

Jaw crusher wear parts working principle is based on the reciprocating movement of the movable jaw plate that compresses and crushes the stone or ore between itself and the fixed jaw plate, as the material enters the zone between the jaws. The fixed jaw plate, movable jaw plate, and cheek plates are called jaw crusher wear parts.

2.Material Selection For Jaw Crusher Wear Parts

Material Selection For Cheek Plates

To protect the jaw crusher body that is the function of cheek plates, on the other hand, the cheek plates don’t direct to crush stones or ores. So jaw crusher cheek plates are manufactured by manganese steel.

Material Selection For Jaw Plates

A Jaw Crusher reduces large size rocks or ore by placing the rock into compression. A fixed jaw, mounted in a “V” alignment is the stationary breaking surface, while the movable jaw exerts a force on the rock by forcing it against the stationary plate. So the fixed jaw plate and movable jaw plate are the main roles in crushing stones or ores. Under different working conditions, select the right jaw plates based on feed material and required end materials, leading to better crusher and cost efficiency, as well as high productivity. There are some kinds of materials for jaw plates.

Mn14Cr2 Jaw Plates

Mn14cr2 jaw plates are used in crushing soft stone. For example, it has a good life when crushing the easy and non-abrasive blasted rock, non-abrasive gravel, and non-abrasive round rock.

Mn18Cr2 Jaw Plates

Mn18Cr2 is the most popular material for casting jaw crusher jaw plates. This Mn18Cr2 jaw plates widely in crushing difficult and non-abrasive blasted rock, medium and non-abrasive,non-abrasive gravel, and non-abrasive round rock.

Mn22Cr2 Jaw Plates

Mn22Cr2 jaw plates are widely used in crushing hard and abrasive stone. Under our technology, its span life much better than normal.

TIC Insert Jaw Plates

This material is developed by Qiming Machinery, it has improved our customer jaw plate by TIC(titanium carbide) insert.  Compare with normal manganese jaw crusher liners, TIC insert wear parts span life can be 2-3 times. Based on our customer feedback, the more hard material to crush, the long span life.

4.Popular Jaw Plate Tooth Profiles And Uses

Crush different kinds of stones or ores, it needs different jaw crusher tooth types to suit. There are some popular jaw plate tooth profiles and uses.

Standard Tooth

Tooth Profile: Standard Tooth

Uses: Suitable for both rock and gravel crushing; Wear life, power requirements, and crushing stresses in good balance; Typical factory installation.

Quarry Tooth

Tooth Profile: Quarry Tooth

Uses: Suitable for crushing Shot Rock in quarries; The flat teeth perform better with abrasive materials; (more wearable tooth material); Causes higher stresses and increases power requirements.

Super Tooth

Tooth Profile: Super Tooth

Uses: Suitable for general use and especially a good choice for gravel crushing; Large mass and special design of the teeth gives long wear life and allows fine material flow down through the cavity along the grooves without wearing the teeth.

Corrugated Recycling Tooth

Tooth Profile: Corrugated Recycling Tooth

Uses: Suitable for crushing concrete; Fine material flows easily through the cavity along the large grooves.

Wavy Recycling Tooth

Tooth Profile: Wavy Recycling Tooth

Uses: Suitable for crushing Asphalt, Material flows easily down through the cavity along the grooves without packing; Normally used in the small setting range with the intermediate plate.

Super Grip Tooth

Tooth Profile: Super Grip Tooth

Uses: Suitable for hard and round natural rock crushing; Provides better grip and capacity; Fine material flows easily through the cavity along the large grooves; Wear life of the fixed and movable jaw dies in good balance.

Wedge & Standard Tooth

Tooth Profile: Wedge & Standard Tooth

Uses: Suitable for both rock and gravel crushing; Thicker lower end of the jaw die and the thinner upper end of the jaw die; Maximizes size of the maximum feed size of the cavity with the maximum nip angle; Wedge jaw die is the fixed one and the Standard jaw die is the movable one.

Anti Slab Tooth

Tooth Profile: Anti Slab Tooth

Uses:  Special jaws designed to crush slabby sedimentary rock; Can also be used when recycling concrete and asphalt slabs.

TIC Insert Tooth

Tooth Profile: TIC Inserts Tooth

Uses: Special jaws designed to crush hard rock; Can also be used when recycling concrete, asphalt slabs, and mining industry.

Corrugated Tooth

 

Tooth Profile: Corrugated Tooth

Uses: Laminar material; Small setting; High amount of fines; Cubical products

Coarse Corrugated Tooth

Tooth Profile: Coarse Corrugated Tooth

Uses: Laminar material; Abrasive material; High amount of fines; Large setting

Sharp Tooth

Tooth Profile: Sharp Tooth

Uses: Increased nip action; Laminar material; Abrasive material; Large amount of fine.

Heavy Duty Tooth

Tooth Profile: Heavy Duty Tooth

Uses: Extremely abrasive material; Increase liner life; No demands on particle shape; Can be combined with CC or ST for improve particle shape.

Wide Wave Tooth

Tooth Profile: Wide Wave Tooth

Uses: Extremely flaky material; Less abrasive material, Muddy material; Good particle shape.

Wide Tooth

Tooth Profile: Wide Tooth

Uses: General applications; Abrasive rock; Less in stock due to that the Z-plate can be fitted on both sides.

S-Tooth
