Jaw Crushers

Not boiling material in the cavity when operating at the best CSS, being able to deal with all material shapes, sizes and hardness’s, fully utilising liner material, plus doing safer and less frequent liner changes are the challenges when using a primary jaw crusher.

Various liner profiles

Hard-Core inserts

Cheek plates

Typical Problems

Jaw liners only wear at the bottom of the fixed jaw & require replacement
Using 2 fixed jaws for one swing jaw
Cheek plates don’t last the full jaw life
Slabby crushed product blocking downstream crushers or SAG mill feed chutes
Insufficient liner life
Localised wear at the lower end of the chamber, leading to:
– Inability to maintain CSS
– Poor liner material utilisation
High carbon footprint thru poor liner utilisation
Safety concerns when changing liners

Makuri Solutions

Longer life liners with better tpoh and psd and safer and easier relines

A lack of attention to proper jaw design by OEMs results in poor product shape and high steel usage on jaw crushers, although this is easily resolved with the correct design. In some cases, we have seen jaw liners requiring replacement after only removing 5-10% of their initial mass, resulting in a large amount of wastage and excessive liner cost.

Simply selecting a new tooth profile is generally not enough to resolve these issues, and a more comprehensive review of the operation is required to meet increased operational demands of better tonnes / operating hour (tpoh) and lower product size distribution (psd).

By utilising the Makuri proprietary Intelligent Design™ processes, we are able to supply the right design and right materials that will ensure Makuri can guarantee a lower TCO and provide greater sustainability to our industry.

Using our safe lifting tools reduces downtime and risk when doing liner changes.
