Jaw Profile Selection For Sandvik Crusher

HIGH CAPACITY JAW CRUSHERS
AND LOW COST PER TON

Sandvik’s top-of-the-line CJ-type jaw crushers are specifically built for your primary applications where resizing is the key objective. They allow the material to be processed within your crushing plant.

To ensure optimum performance, the jaw crusher needs to have a good feed level and a homogeneous feed.

Our jaw crushers are of the single-toggle type and feature a deep, symmetrical crushing chamber, a large feed opening for its size, and an ideal nip angle that offers smooth material flow and high reduction efficiency.

Jaw crushers are normally capable of a reduction ratio of 1:2 or 1:3. This ratio is affected by the feed material’s bulk density, crushability, size distribution and moisture content – among other factors – and will affect the crushing chamber performance. The nip angle is the angle between the fixed and moving jaw plates. Our Sandvik CJ crushers have an optimum nip angle in the 16-23 degree range.

SELECTION OF JAW PLATES

Sandvik offers seven teeth patterns and up to three alloy selections (M1, M2, M8) to suit the different types of quarrying and mining applications. Our patterns include Wide Teeth (WT), Wide Wave (WW), Corrugated (C), Coarse Corrugated (CC), Sharp Teeth (ST), Heavy Duty (HD), Heavy Duty Ultra-Thick (UT).

M1 is the standard alloy, offering high resistance to shock and impact. It also work well with hard rock. Our M2 and M8 alloys offer high resistance to abrasive rock, but have lower resistance to shock and impact.

The optimal jaw plate selection can be determined based on the rock/ore type characteristics (WI, AI) and the feed characteristics (friction, gradation).

WIDE TEETH (WT)

Good wear resistance. For feed with a lot of fines. Can be used on both fixed and moving sides.

WIDE WAVE (WW)

For slabby and less abrasive feed material. Feed is relatively easy to crush. Good top-size control.

SHARP TEETH (ST)

For flaky feed material with a lot of fines. Good gripping ability. Very good top-size control. Highly recommended if the AI is not too high.

CORRUGATED (C)

Suitable for less abrasive material. Good for small CSS settings. Good top-size control.

COARSE CORRUGATED (CC)

For abrasive material. For feed with a lot of fines. Used for large CSS settings. Good top-size control.

HEAVY DUTY (HD)

For very abrasive material. Less top-size control. Can be combined with a CC moving plate.

HD ULTRA-THICK (UT)

For very abrasive material. Less top-size control. Fixed plate based on our HD pattern with an extra 30 mm thickness for longer wear life. To be used with the CC moving plate.
