What is crusher wear parts?

A crusher is made up of hundreds of parts. In the crusher, the parts that mainly crush the ore or stone raw material and need to be replaced regularly are called the crusher wear parts.

Wear Parts Types

In different types of crusher plant, there are different wear parts:

  • In the jaw crusher, the wear parts are fixed jaw plate, movable jaw plate, and protection plate;
  • In the cone crusher, the wear parts are mantles, concaves, and feed cone;
  • In the impact crusher, the wear parts are blow bars and impact plate;

Austenitic manganese steel

Austenitic manganese steel is a very tough and ductile material having a high impact toughness. Mn-steel is rather soft material having an initial hardness of approx. 220-250 HV. The wear resistance of manganese steel is based on a work hardening phenomenon.
When the surface of Mn-steel is under heavy impact or a compressive load, it hardens from the surface while the base material remains tough. The depth and hardness of work-hardened surface vary depending on application and Mn-steel grade.

The work-hardened layer can be between 10 and 15 mm deep and hardness can be up to 600 HV in primary applications. In fine crushing applications, the work-hardened layer is thinner and hardness is usually around 350-500 HV.

The Mn/C ratio and amount of Cr are not only relevant when it comes to the wear resistance of Mn-steel. The entire casting process needs to be well optimized to produce high-quality wear parts. Below are a few critical steps to producing high-quality Mn-steel castings.

It all begins with raw material selection where raw materials are carefully selected for melting in order to get the material analysis inside strict specifications and to reduce the number of certain impurities. During melting and pouring the temperatures are carefully controlled in order to achieve fine grain structure for the castings. At the same time samples are taken to verify the material analysis and adjust if necessary. Melted metal is then poured into sand molds where the metal slowly solidifies. The molds have carefully designed feeding and gating channels to ensure solid castings.

Heat treatment is another critical step to producing ductile high-quality castings. Temperature, time and quenching need to be well controlled in order to avoid grain boundary carbide formation. After the heat treatment has been completed, castings are machined according to strict tolerance to ensure a perfect fit for the crusher.

Besides the casting, the cavity shape has a significant effect on the performance of the crusher and lifetime of wear parts. Cavity shapes are optimized by using sophisticated simulation tools and continuous testing and follow-up.

High chromium irons

This material group is offering classical solutions as well as more specialized solutions. These materials are of low cost and a good choice for many applications. The wear resistance is based on the hard carbides on the relative hard matrix, still, the composition and structure can be tailored considerably. Generally, high chromium irons are commonly used in abrasive wear applications

What is wear?

Wear is a material loss on the surface by means of several different mechanisms. The two main wearing mechanisms in the crusher cavity are:

  • Abrasive wear
  • Fatigue wear

The main wearing mechanism in the crusher cavity is abrasive wearing. Fatigue wear is also present as wear parts are subjected to multiple compression or impact loads.

 

Abrasive wear

Crushers typically compress the feed material between the fixed and movable wear parts. Besides the breakage of the feed material, this is also wearing material away from the wear part. Wearing micromechanisms are:

  • Microploughing
  • Microcutting
  • Microcracking
  • Microfatigue

During the crushing cycle, gouging or high-stress abrasion is present depending on the particle size of feed material. Between the crushing cycles when particles of feed material are sliding against wear parts, low-stress abrasion is present.

Wear Lifetime

There are several different factors that affect the wear of wear parts.

  • Type of wear
  • Environmental factors
  • crusher operating parameters
  • feed material
  • wear part properties
Wear lifetime of crusher wear parts

5 kinds of factors Wear lifetime

Casting Methods

There are three common casting methods for casting crusher wear parts:

  • Lost Foam Casting. It suits to cast some small and large quantity wear parts, such as side plate, cheek plate, wear liner, etc.
  • Sand Casting. It is the most popular casting method in casting wear parts. Almost all parts can use this casting method.
  • V-method Casting. It suits to cast large quantity standard parts, such as mill liner, cone crusher mantle, gyratory crusher concave segments, etc.
