The pearlitic molybdenum steel lifting bar is precisely matched with the lifting conditions of the grinding mill.

Full of features, solving the pain points of material transportation!

Choose the right one and extend the lifespan of the lifting bar by 3 to 5 times.

Save 40,000 to 80,000 yuan in replacement costs every year.

The material lifting efficiency of the grinding mill has steadily increased by 20%.

The conveying is continuous without interruption.

I. Core Product Features of Pearlitic molybdenum Steel Lifting Bars

Pearlite matrix + molybdenum alloy strengthening: containing 0.8%-1.2% chromium, 0.2%-0.5% molybdenum.

The proportion of pearlite structure is ≥90%.

The matrix is dense and the strength and toughness are balanced.

The lomolybdenum element works in synergy to enhance wear resistance and impact resistance.

Its wear resistance is three times higher than that of ordinary carbon steel lifting bars.

Precise balance of hardness and toughness: After quenching and tempering treatment, the surface hardness reaches HRC38-45.

Impact toughness ≥80J/cm².

It is both wear-resistant and not prone to breakage.

Eliminate the defect of being “hard and brittle”.

Under the high-frequency impact and material friction inside the mill.

The ordinary lifting bar breaks within 1 to 2 months.

It can be used stably for 6 to 12 months.

Reduce downtime for replacement.

Anti-slip grab structure design: Trapezoidal anti-slip patterns are set on the surface.

Avoid material “slippage” and “backflow”.

It is suitable for the low-speed and high-load lifting requirements of the mill.

The material conveying efficiency has been increased by 25%.

Precise adaptation to equipment specifications: Customize length and thickness according to the model of the mill.

Its adaptability far exceeds that of general improvement strips.

Heat-resistant and corrosion-resistant dual compatibility: Can withstand temperatures below 400℃ for a long time.

The frictional heat of the mill and the residual heat of the material will not cause the material to soften.

A passivation film forms on the surface to resist moisture and pulp erosion.

It does not rust in damp outdoor or mine conditions.

Structural reinforcement and anti-deformation: Longitudinal reinforcing ribs are added to the back.

Edge arc transition eliminates stress concentration.

It can withstand the high load of the mill operating continuously for 24 hours.

Its resistance to bending deformation is 50% higher than that of ordinary flat lifting bars.

Avoid side leakage of materials due to deformation during the conveying process.

Ii. Four Core Advantages Derived from Characteristics

Heavy-duty, wear-resistant and long service life: Relying on pearlitic molybdenum steel material and anti-slip structure.

In the lifting of hard materials such as ores and slag.

Stable use for 6 to 12 months.

It is 2 to 3 times that of a regular boost bar.

There is no need to frequently shut down the machine for parts replacement.

It is suitable for 24-hour continuous production conditions in mines and building materials factories.

Material lifting efficiency soars: Anti-slip patterns enhance material grasping force.

The material conveying capacity is increased by 20% to 30%.

Avoid “idling” and “backflow”.

The overall production efficiency of the grinding mill has been improved simultaneously.

The insufficient material grasping of the ordinary lifting bar leads to delayed conveying.

The exclusive upgrade bar makes the material flow smoother.

Comprehensive upgrade of equipment protection: Double the lifespan of the entire machine.

Enhance the comprehensive benefits of the production line.

Flexible and efficient processing and adaptation: It can customize irregular structures according to the special requirements of the equipment.

Adapt to complex installation scenarios.

Installation does not require major equipment modifications.

Fixed with anti-slip bolts.

Convenient for construction, saving 30% of installation time.

Iii. Five precise application scenarios

Ball mill material lifting: Enhance grinding efficiency.

Bucket elevator accessories: Compatible with building materials production lines.

Metallurgical slag conveying equipment: Facilitating the recycling and conveying of metallurgical waste slag.

Mine hoisting equipment: Ensuring the stability of mine conveyor lines.

Building materials grinding machine parts: Wear-resistant and non-polluting to raw materials.

Ensure the quality of finished building materials.

Suitable for large-scale production.

Ⅳ. Select the right four key criteria for improvement

The material composition strictly meets the standards: high-quality lifting strips contain 0.8%-1.2% chromium and 0.2%-0.5% molybdenum.

The proportion of pearlite structure is ≥90%.

Request the material inspection report for verification.

Substandard composition can lead to a sudden drop in wear resistance and impact resistance.

It wears out and breaks within one month. We must resolutely prevent defective products.

Process guarantee characteristics are brought into full play: The “quenching and tempering treatment + mechanical processing” process is preferred.

There are no sand holes or cracks on the surface.

The anti-slip patterns are neatly formed.

It has a lifespan 30% longer than that of the casting process.

Poor-quality lifting strips are prone to anti-slip patterns falling off and the base cracking.

The core features cannot be brought into play.

Dimensional precise matching equipment: Confirm the length, thickness and curvature according to the model of the hoist.

The error is ≤1.5mm.

For instance, a Φ3m ball mill is compatible with lifting bars that are 12mm thick and 1500mm long.

Size mismatch can lead to poor adhesion.

Material side leakage + accelerated wear.

Check the mechanical performance parameters: avoid being “hard and brittle” or “tough and not wear-resistant”.

Ⅴ. Three Practical Tips for Extending Your Life

Control the feeding and working conditions: Prevent materials exceeding the particle size from entering the equipment.

A protective cushion layer should be added for over-temperature conditions.

Protection and enhancement strip.

Super-sized materials can impact and damage the anti-slip patterns.

Excessive temperature can soften the material.

It leads to a reduction of one third in lifespan.

Regular inspection and maintenance: Shut down the machine every two weeks to check the wear of the lifting bars and the tightness of the bolts.

If the anti-slip pattern is worn by more than 50%, it should be repaired by welding in time.

Tighten the loose bolts to prevent displacement.

Small wear and tear will expand rapidly if left untreated.

The displacement will accelerate the wear of the equipment body.

The maintenance cost has doubled.

Standardized installation and adaptation: Ensure that the lifting strip is closely attached to the surface of the equipment during installation.

Reserve the gap for thermal expansion and contraction.

Avoid cracking caused by welding stress concentration.

Improper installation will damage the structural integrity of the lifting bar.

Shorten the service life.

It affects the lifting effect of materials. Read More
