Impact Crusher Wear Parts

Maximizing Wear Life

The Aim of the Game is to Make the Most Money Per Produced Ton.

Crushing materials consumes wear parts, resulting in recurring operating costs. The higher the wear rate per produced ton, the higher your operating costs. Impact crusher wear parts include hammers, wear plates, and rubber products such as conveyors and skirting. The wear rate depends on the characteristics of your wear part and also on the characteristics of your feed material. Material abrasiveness, fines content, moisture, material stickiness, and hardness may result in higher-than-normal wear.

Failing to Monitor and Manage Wear Results in High Operating Costs.

How you operate and select your impact crusher wear parts significantly affects your operating costs. If you are not proactive regarding wear, you…

  • change wear parts more frequently.
  • chase parts orders constantly.
  • face more downtime and less productivity.
  • lose money to high wear.

This is How to Make More Mone Per Ton:


1. Select the Right Hammers for Each Application 

Impact crusher hammers are the single biggest and most expensive wear item in your impact crusher. Different metallurgical compositions show different wear characteristics with different materials. For example, hammers made of cast chromium are ideal for crushing natural stone due to their hardness and composition. For recycling applications, softer hammers made of martensitic cast iron are more suitable because they absorb impact without breaking when crushing reinforced concrete.

2. Use Thicker Wear Plates for Abrasive Natural Stone Applications 

Thicker wear plates provide more wear life. RUBBLE MASTER impact crushers are equipped with ¾” (20 mm-) thick Hardox 450 wear plates as standard. In highly abrasive natural stone applications, thicker 1¼” (30 mm) wear plates extend the wear life, resulting in less downtime and higher profits.

3. Fit an Additional Belt Guard Plate for Natural Stone Applications 

RUBBLE MASTER offers an additional belt guard to provide optimum protection of the main discharge belt against heavy wear when processing hard stone. So how does that work?

The optional wear and guard plate is a steel plate attached to the belt guard base frame. It ensures a smooth flow of material and prevents materials that could cause damage from contacting the belt.

Note: This option is recommended for natural stone applications only. It could cause blockages if used for recycling applications. 

4. Fit Additional Cladding to the Radiator 

Airborne fines from very dry feed material may result in radiator wear. The radiator fan accelerates the particles, which almost sandblast your radiator, damaging it and causing leaks.


RUBBLE MASTER offers an optional blast guard (a stainless-steel mesh) that catches the material between the radiator and fan. As a result, material doesn’t build up in the cooling fins, extending the service life of your radiator.

5. Clean the Crusher Every Day 

Material buildup inside the crusher that touches the hammers results in premature grinding down of the hammers. That is why it is important to clean the crusher daily, especially around the rotor, and remove any accumulated material.


Here are some of the most vulnerable spots around a mobile impact crusher:

  • Material sticking to the impact plates and wear plates
  • Material build-up underneath the crusher (fines, or machine sinking into the ground)
  • Material pegging and blinding the pre-screen
  • Material pegging and blinding the screen attachment
  • Fines building up inside the engine compartment


RUBBLE MASTER’s Ground Based Service makes it easy to perform this task with ease on a daily basis. Check out this blog article for a best practice daily routine.
