How to choose the correct blow bar material?

2026-02-04

Choosing the wrong crusher blow bars material will have a series of serious negative impacts on the operation and economic benefits of an impact crusher. So, how should we choose the correct material for impact crusher parts?

1. High-manganese steels: MN13CR2, MN18R2, and MN22CR2.

Mn steel offers advantages in wear resistance and toughness, but its wear resistance is not as good as high-chromium steels.

2. High-chromium steels: CR22 or Cr26.

Cr steel offers advantages in wear resistance, but its disadvantage is that it makes the blow hammer brittle (poor toughness), unable to absorb impact energy during crushing and prone to breakage.

Impacts:

Secondary Equipment Damage: Broken hammer fragments fly at high speed, potentially damaging the crusher liner, impact frame, and even the rotor, resulting in high repair costs and extended downtime.

Safety Hazards: Flying fragments pose a serious safety hazard, potentially harming equipment and personnel.

3. Materials with added Mo include: CR27MO0.5, CR27MO1, and CR27MO2.

The advantage of Mo is that it increases microstructure and toughness, but it comes at a high price.

How to interpret the material report provided by the manufacturer?

In addition to ensuring that the main material components, such as Mn and Cr, match the quoted value, the lower the P and S values, the better; these are considered impurities.

Common Misconception: Higher hardness is not always better. For applications involving high impact and hard materials (such as granite crushing), sufficient toughness (e.g., using high-toughness alloy steel) is crucial. For applications involving high abrasiveness but low impact (e.g., limestone crushing), a higher hardness (e.g., using high-chromium cast iron) is recommended.

The correct selection method:

Provide accurate information: Provide ONA Casting with the crusher model, material type, hardness, feed size, and expected output. ONA's professional engineers can recommend the most suitable material, such as high-chromium cast iron, high-manganese steel, and alloy steel.

If price is the only consideration, the savings in blow bars purchase costs may far outweigh the significant losses caused by frequent downtime, equipment damage, and reduced production.

Therefore, choosing the right material is crucial.

How to choose the correct material for jaw cusher plate?

2026-02-04

Metso C80 Jaw crusher are widely used in mining. Their main wear-resistant component is the jaw plate. However, many users lack dedicated engineers or, due to purchasing older, secondhand machines, cannot find relevant information and have little understanding of the materials used for the jaw plates and their heat treatment processes. Today, we will provide a detailed introduction to the practical applications of crusher jaw plates.

The jaw crusher operates on a reciprocating compression principle: the motor drives the belt and pulley, which in turn moves the moving jaw up and down via an eccentric shaft. When the moving jaw rises, the angle between the jaw crusher toggle plate and the moving jaw increases, pushing the moving jaw plate closer to the fixed jaw plate. Simultaneously, the material is crushed or split, achieving the crushing purpose. When the moving jaw descends, the angle between the jaw crusher toggle plate and the moving jaw decreases, and the moving jaw plate, under the action of the return rod and spring, moves away from the fixed jaw plate. At this point, the crushed material is discharged from the bottom of the crushing chamber. With the continuous rotation of the motor, the moving jaw of the crusher performs periodic movements to crush and discharge materials, achieving mass production.

Jaw crusher wear plates are divided into moving jaw plates and stationary jaw plates(Some regions call it mantle concave). Depending on the model of the jaw crusher, there are various tooth profile sizes, generally made of high-manganese steel, i.e., high-manganese steel jaw plates. High-manganese steel has a history of over 100 years. Under conditions of strong impact abrasive wear, high-manganese steel has excellent wear resistance and is therefore commonly used in machinery and equipment in mining, building materials, and thermal power plants. Applicable materials include coal gangue, feldspar, barite, and basalt. Under low-impact conditions, the work hardening effect is not significant, and high-manganese steel cannot fully utilize its material properties.

Research has found that three major factors affect the wear resistance of high-manganese steel jaw plates during the casting process: material, purity of raw materials, and heat treatment process. Material is the fundamental element determining the wear resistance of high-manganese steel jaw plates. Adding chromium to high-manganese steel (Mn18Cr2) directly increases its wear resistance. Some manufacturers use recycled high-manganese steel as raw material, or mixed in the new raw material, which introduces harmful sulfur and phosphorus elements into the newly cast jaw plates, affecting their service life. Finally, regarding the heat treatment process of high-manganese steel jaw plates, rapid heating at low temperatures can cause cracking. Therefore, the correct procedure is to maintain a heating rate of <80℃/h below 350℃ and <100℃ above 750℃, when the casting is in a plastic state and can be rapidly heated. At 1050℃, determine the holding time based on the casting thickness (usually 1 hour/25mm); then rapidly raise the temperature to approximately 1100℃ and hold for half an hour before removing from the furnace. The casting must be immersed in water as soon as possible after removal from the furnace; the time between removal and immersion should not exceed 45 seconds, and even shorter in winter. Slow heating at high temperatures, insufficient holding time, and excessively long intervals between removal and immersion (not exceeding 0.5 minutes) all negatively impact the quality of the high-manganese steel jaw plates.

Striving for greater wear resistance in jaw plates does not necessarily require continuously increasing the proportion of high-manganese steel. Mn13Cr2 and Mn18Cr2 are suitable for most jaw plates, while Mn22Cr2 is suitable for extremely cold regions. For regions with suitable temperatures, choosing Mn22Cr2 compared to Mn18Cr2 will not only fail to significantly extend the service life but will also increase procurement costs. For better results, consider inlaying with cemented carbide, which can achieve a service life 1.5-1.8 times that of Mn18Cr2.

How to understand the material inspection report?

2026-02-04

I believe many customers know that when purchasing crusher wear-resistant parts, you can ask suppliers to provide material inspection reports. The material inspection reports provided by different suppliers are slightly different. Even the inspection reports of the same manufacturer may have some differences in different orders. Today we will briefly describe the meaning of each chemical element in the material inspection report.

Here is a sample suit for Nordberg HP300 feed plate, PN: 1055981158, material Mn13Cr2. (This material also used for crusher mantle and crusher concave, China jaw plate, cheek plate jaw crusher, etc.)

metso hp300

As the name suggests, Mn13Cr2 means that the high manganese steel content is 13% and the high chromium content is 2%. Therefore, as long as the content values are within the range, there is no problem.

The advantages of high manganese steel are wear resistance and good toughness, but high chromium steel has better wear resistance and is more expensive. The disadvantage of high chromium steel is that it is very brittle and the product is easy to break during use, so the more chromium steel, the better. The life of Cr is 2-2.5 times that of Mn.

P and S stand for phosphorus and sulfur respectively. They are impurities, so the lower their content, the better.

In addition to the above materials, we often encounter Mo. Its function is to increase the fineness of tissue particles and increase toughness, but the price is very high.

Titanium carbide, also known as cemented carbide, is expensive, but its lifespan is 1.5-1.8 times that of Mn.

If you are not sure what material is suitable for you, you can contact us and tell us the raw materials you want to crush, and our engineers will recommend the right material for you.

What are the different manufacturing procedures for bowl assembly？

2026-02-04

The production of the bowl assembly integrates advanced materials science and precision manufacturing technologies to ensure extreme durability, dimensional accuracy, and structural reliability as the core component of a cone crusher.

The key process flow is as follows:

1.Stringent Casting Process：Selected high-strength alloy steel is used to ensure the base material possesses excellent impact resistance and wear performance.Casting simulation software is employed to digitally simulate and optimize the pouring, cooling, and solidification processes.

2.Precision Heat Treatment：The rough casting undergoes a combined normalizing and tempering heat treatment. This process refines the grain structure, eliminates internal casting stresses, and uniformly enhances the hardness, toughness, and fatigue resistance of the material.

3.High-Precision CNC Machining：Critical mating surfaces—such as the threads that engage with the adjustment ring and the register (spigot) that fits with the main frame—are precision-machined using large CNC boring and milling machines.

4.Comprehensive Non-Destructive Testing (NDT)

The finished Bowl Assembly body undergoes a rigorous multi-layered NDT inspection system:OPI (Oil Penetrant Inspection): Detects minute surface cracks or flaws.UT (Ultrasonic Testing): Examines the internal structure for voids, inclusions, or delaminations.MPI (Magnetic Particle Inspection): Identifies surface and near-surface defects, especially crucial for ferromagnetic materials.

Core Components and Working Principleon

1. Sphere: Typically made of high-density cast steel (such as the ZG270-500 you mentioned), with a diameter ranging from 0.8 meters to several meters, and weighing several tons or even tens of tons.

2. Suspension System: Consists of slings, chains, and a release mechanism from a crane (or a dedicated demolition machine).

3. Working Principle: The operator manipulates the crane to lift the steel ball to a certain height. By swinging or directly releasing the ball, it accelerates along a "pendulum" trajectory to strike the target (such as walls, columns, or floor slabs). At the moment of impact, the ball's enormous mass multiplied by its velocity generates extremely strong kinetic energy, sufficient to crush concrete, brickwork, and other building materials, causing the structure to crack, break, and ultimately collapse.

Main Features

1.Immense power: Capable of quickly destroying sturdy reinforced concrete structures.

2.Simple structure: The equipment itself requires virtually no maintenance and is highly reliable.

3.Low cost: Compared to some high-tech demolition methods, the initial investment and operating costs are low.

4.Wide applicability: Particularly suitable for demolishing independent, tall structures such as bridges, chimneys, and large industrial plants.

5.No electricity/hydraulic power required: The ball itself requires no power, relying solely on a crane.

Modern Application Scenarios

1. Demolition of large industrial facilities: such as abandoned steel mills, power plants, cement plants, and other spacious factory buildings.

2. Demolition of bridge piers and abutments.

3. Controlled demolition of tall structures such as chimneys and water towers (by precisely impacting the base to cause them to collapse in a predetermined direction).

4. Secondary crushing: used to break up large concrete blocks after initial building demolition.

5. Emergency rescue: used for rapid demolition of dangerous structures on the verge of collapse after earthquakes or fires.

What is daily maintenance for a jaw crusher?

2026-02-04

The jaw crusher is a core piece of crushing equipment in industries like mining and construction. Its stable operation directly impacts production efficiency. Routine maintenance not only reduces downtime due to failures but also significantly extends the equipment's service life.

Pre-Startup Inspection

Check the tension of the V-belt, jaw plate, and the tightness of all bolts.
Inspect the equipment casing and frame for cracks and loose bolts.
Check the oil level in the hydraulic tank to ensure it is between the oil gauge lines. Check the hydraulic quality and verify that the hydraulic pump is operating properly and that there are no leaks in the oil pipes.
Clear any remaining material from the feed inlet to avoid stalling during startup. Check the discharge opening clearance to ensure it meets production requirements to prevent substandard crushing or equipment overload.

Inspection During Operation

Bearing temperature is within the normal range.
The tie rod spring is normal.

Regular Maintenance After Shutdown

Lubricate every 40 operating hours.
Lubricate the discharge opening adjustment device and inspect the rubber cover (for mechanical adjustment of the discharge opening).
Inspect the cheek plates for wear and replace if necessary.
Check the toggle plate for alignment, straightness, and cracks.
Inspect the toggle plate seat and rubber seal, and clean the toggle plate seat surface if necessary.
Check the tightness of the frame mounting bolts.
Inspect the flywheel.
Inspect the rubber shock absorber pads for wear.

Whats about Bronze Copper Spare Parts？

2026-02-04

When it comes to keeping your crusher running at peak performance, copper parts play a critical yet often understated role. These components, including eccentric bushings, socker liner, main frame pin bushing, trush washer/bearing and countershaft bushings are the quiet champions inside the crushing.

Main components include:

1. Eccentric Bushing: Installed inside the eccentric steel sleeve, located on the outside of the main shaft. Its core function is to support and guide the movement of the eccentric shaft, protecting the main shaft and eccentric steel sleeve, preventing wear of the eccentric steel sleeve, and ensuring smooth and efficient crushing action.

2. Socker Liner: Installed at the top of the main shaft. Its working surface has oil grooves and mates with the spherical surface of the moving cone, supporting the entire conical main shaft and providing a low-friction spherical bearing, allowing the moving cone to swing freely.

3. Main Frame Pin Bushing: Installed inside the horizontal shaft housing, one at each end. Its main function is to prevent direct contact between the horizontal shaft and the inside of the horizontal shaft housing, providing lubrication (bearing) and protection.

4. Thrust Washer/Bearing: Divided into upper and lower thrust bearings. They work together under the action of a lubricating oil film, enabling the eccentric sleeve assembly to perform smooth eccentric rotational movement.

5. Countershaft Bushing: Installed in the horizontal shaft housing, one at each end. Located between the horizontal shaft and the inner wall of the housing, it provides lubrication and protection, preventing direct contact and wear between the two.

The following is a list of the main copper components suit for Symons, Metso, Sandvik and Spring cone crushers：
