of crushers, whether in aggregates, mining,

recycling or any other applications. Drawing

on our extensive experience and expertise, we

will make sure customers always have the right

wear parts for the highest quality of production

– and for increased profitability.

Customer knowledgeMetso is in the business of contributing to

customer success. This means working closely

with all customers with a view to understand-

ing their specific needs and business environ-

ments, and ultimately to providing the tools

that are needed for reliable production.

Process knowledgeNo chain is stronger than its weakest link.

Metso is a knowledge-based company with

an in-depth understanding of every link in the

customer’s production process. This is a crucialprecondition for achieving optimal results.

Product knowledgeMetso wear parts are developed on the

strength of both our customer knowledge and

our process knowledge. We have a full range

of high quality wear parts for every type of

crusher and every application.

Linking innovation through Metso The creation of Metso through the merger

of Nordberg and Svedala brought together

more than 200 years of experience in crushing

technology. All in all we have delivered some

30,000 crushers, and we have a presence in

more than 100 countries around the world.

The merger also put us in a solid financial

position to continue at the forefront of re-

search and development.

ncreased profitability

Lowest possible production costs The price of wear parts themselves is not

what matters – what matters is the production

cost/ton of crushed product. We have the

knowledge to combine long service life and

maximized production of value gradation.

Best end product quality, quantity

and gradation

The choice of working wear parts has a key

impact on many production factors – not least

the quality of the end product. The type of raw

material is one of the main considerations inthe choice of wear parts. Metso has the exper-

tise and knowledge to make these choices.

Whatever the application, we have the tools to

make production more cost-effective.

Wear parts that protectMetso certified wear parts will protect your

crushing equipment, prolong its service life

and at the same time preserve its trade-in

value. Metso has extensive experience and

competence in all kinds of wear material,

including Trellex wear resistant products.

we have the right wear parts

Gyratory crushersMetso offers a wider range of equipment and wear parts for high capacity

gyratory crushers than any other manufacturer on the market. Our wear parts for the

crushing chamber give the highest possible throughput with less stress on different

components, reduced power requirements, and evenly distributed wear patterns on both

the mantle and concaves.

Jaw crushersMetso jaw crushers are based upon a revolutionary modular, non-weld-

ed frame construction. The design offers superior fatigue strength and

reliability and gives numerous mounting options.

Combined with high-quality wear parts that are easy to replace, this

translates into exceptionally high capacity utilization, and cost-efficient

crushing.

Cone crushersMetso is committed to developing the best

possible wear parts for cone crushers as well:

this is crucial for maximum efficiency and

reliability in production. Today more than 2,000

Metso gyratory cone crushers are at work all over

the world, a testimony to their reliability and all-

round versatility.

Impact crushersMetso has over 50 years’ experience in impact crushers,

both vertical and horizontal shaft type crushers.

Our impact crushers feature a unique combination of

heavy rotor design, wear material and crushing chamber

design. The unique design of our impact crushers reduces

maintenance needs and facilitates adjustment in primary,secondary, tertiary as well as in recycling applications.

Other wear partsMetso offers almost any type of wear protecting products. Other wear parts available from

Metso include Trellex products that are made of rubber, polyurethane and ceramics – alone or

in combination. This is where our engineering shows to advantages – through our competence

to combine different materials.

Knowledge that offers

Metso is the world’s leading knowledge based

company in the crushing business. The depth

and breadth of our knowledge and expertise

gives every customer that extra bit of competi-

tive edge.

Main factors in abrasive wearingWearing occurs through various different

mechanisms, including adhesive, fatigue and

abrasive wearing. In the case of crusher wear

parts, whether working or protecting, the main

mechanism involved is abrasion by foreign

particles, which is further divided into three

types: gouging, grinding and scratching

abrasion. Depending on the crushing applica-

tion and the properties of the crushed material,

the wearing is a combination of these three

abrasion components.

Wear resistant material The most important feature of wear resistant

materials is their ability to prevent abrasive

particles from penetrating the wear part surface.

The choice of wear resistant material and itskey properties will depend upon the application

and the properties of the crushed material.

Austenitic manganese steelAustenitic manganese steel has unique proper-

ties for wear resistant applications. The most

notable of these properties are its toughness

and fatigue strength. When the surface of

austenitic manganese steel comes under an

impact load, a work hardening process occurs.

The initial hardness of the material is about 220

HV, whereas the hardened layer on the surface

can be up to 600 HV. The hard layer thicknesscan be 5-10 mm, depending on the impact load.

Austenitic manganese steel is ideally suited for

applications with high reduction ratios and

hard feed materials.

Main wearing processes in crushers

The main type of wearing that occurs in crushers will depend

upon the reduction ratio and the crushability of the feed material.

The design of effective wear parts relies crucially on this

knowledge about the crushing process.

Work hardening vs. final hardness

process and a good hardness profile.

Chrome iron and martensitic steels The wear resistance of chrome is based upon

hard iron and chromium carbides in the

martensitic matrix. The matrix can have a

hardness of 500-700 HV, depending on the

heat treatment process, whereas the hardness

of the carbide formation is up to 2500 HV.

Chrome iron has certain limitations as wear

material due to its low toughness. It is best

suited for applications where the feed material

is abrasive, but where the reduction ratio and

feed strength are not very high.

Boron steelBoron steels are hot rolled plate materials. Its

wear resistance is based on the high initial

hardness of the martensitic matrix. Its nal

hardness, strength and toughness depend

upon the heat treatment procedure used. But

hardness can be 300-500 HV and yield

strength 400-1000 MPa. This material is mostly

used in fabricated protective wear parts:

linings, cheek plates, etc.

Wear in operation

With wear patterns varying in different applications, it is

essential to have the right material in the right place to

achieve the best possible cost-efficiency in production and

get the longest possible service life out of the production

equipment. Metso has the know-how to make sure that thisis indeed what happens.

Our knowledge and expertise in crus-

hing technology covers the whole chain

from design to manufacturing and ins-

tallation. It is this broad know-how that

guarantees superior reliability in everyapplication.

of environmental management we follow the ISO

14001 standard.

No compromises in performance The world’s biggest supplier of crusher wear parts,

Metso has a strong R&D infrastructure particularly in

areas of metallurgy and part design. Over the years

our eorts in R&D have considerably increased the

service life of wear parts. Our product range includes

all wear part materials for all crushing applications,

from compressive crushing to impact crushing, from

different manganese steel grades to chrome iron.

Experts in wear resistant steelsClose process control is essential to the production

of high-quality manganese steel, starting from the

selection of raw materials with a low content of

impurities. Every step of the manufacturing process,

including all chemical analyses and melting and heat

treatment, is recorded to make sure that the me-

chanical properties of the wear parts are as constant

as possible.

Accurate fit in every crusher The final step in the manufacturing process is

machining. This is to ensure an accurate fit in every

crusher and correct chamber shapes. Certified Metso

wear parts always give the best possible product

quality and capacity and maintain the trade-in value

of production equipment.
