Material Guide

Professional selection guidance to avoid losses caused by improper selection.

• Operating Condition Analysis:Based on the customer's crushed stone type (granite, iron ore, limestone, river pebbles, etc.), stone size, weather conditions, and equipment operating time, and combined with the performance characteristics of various materials, we scientifically match the best material solutions to ensure that the products have maximum wear resistance and service life.

The core advantages of choosing the right materials:

1. Reduced replacement time, increased production time, and higher output: High-quality wear-resistant materials significantly extend the lifespan of parts, reducing downtime for replacements. Each replacement saves hours or even days, translating that time into effective production, directly increasing equipment uptime and hourly output, resulting in greater output.

2. Reduced labor costs: Lower replacement frequency means less manpower for maintenance, while simplifying installation and maintenance processes and reducing reliance on highly skilled workers. Over the long term, labor costs decrease significantly, allowing maintenance teams to focus more on equipment optimization rather than frequent repairs.

 

• Model matching: A complete model database has been established for various series of models (HP, C, CH, CS, etc.) of mainstream brands such as Metso, Sandvik, Symons, and Terex etc. Installation dimensions and fit tolerances have been strictly verified to ensure that spare parts are fully compatible with the original machine.
• Recommended wear-resistant component combination: The cutting ring and liner should be properly matched. When purchasing liners, it is recommended to buy wear-resistant components such as the cutting ring, as their main purpose is to protect the liner and extend its service life.

Installation Guide

We provide professional installation support to ensure the correct use of the product.

• Installation Manual: Provides detailed illustrated or video installation guides.

Eg: The installation video for the HP6 cone crusher eccentric assembly can be summarized in three steps:

• Clean and place the thrust bearing gaskets.
• Use a special lifting tool to smoothly install the frame bushing.
• Check the gear backlash and contact with the main shaft. For a more detailed understanding of the installation process, please watch the video below.

Eg: If you are interested in the HP cone crusher head assembly installation guide, please watch the video below.

Eg: The wedge is tightened using bolts during installation.

• Torque parameters: Provide standard tightening torque values for critical bolts (such as lock bolts, jackscrew, etc.) to ensure secure and reliable installation.
• Installation precautions: Clearly define the required wedge penetration depth, wedge clearance adjustment methods, mating surface cleaning standards, and anti-loosening measures to avoid premature failure due to improper installation.
• On-site guidance: Based on customer needs, we provide remote video guidance or on-site installation guidance services to ensure standardized installation and accurate debugging.

Problem Diagnosis and Solution

Eg: After-sales service provided for lubrication systems.

We have established a comprehensive technical service system to ensure that customer issues receive a professional response as soon as possible. After the customer provides a fault description, photos or videos, the engineer will quickly diagnose and analyze the fault, accurately locate the cause (such as abnormal wear, improper installation, overload, etc.), and provide solutions to guide on-site handling.

Drawings and Surveying Services

Solving the problems of customers lacking drawings and needing to replace old parts.

• Used Part Measurement: After the customer provides the used part, a 3D laser scanner is used to obtain accurate data. Combined with professional software modeling, this ensures that the dimensions of the new product are completely consistent with the original parts, accurately restoring the dimensions.
• Drawing confirmation: After the survey is completed, the drawings are provided to the customer for review and confirmation to ensure that the dimensions, fit tolerances, etc. fully meet the requirements before production.
• 3D Modeling: For complex components, professional software is used to create 3D models, providing multi-angle previews and dimension annotations to intuitively display the product structure and facilitate customers in confirming installation compatibility in advance.
• Reverse engineering: Performing 3D scanning and reverse design on worn parts to analyze the causes of failure, optimize structural dimensions and material properties, and make new products more durable and adaptable.

Technical Training

We offer technical training to help customer teams serve the end market more professionally and efficiently.

• Product Knowledge Training: Material properties, applicable conditions, and selection principles to help customers choose the right products.
• Installation & Maintenance Training: Standard procedures, torque parameters, clearance adjustment, and daily maintenance tips to extend product lifespan.
• Fault Identification Training: Early fault detection through abnormal sounds, vibrations, current changes, and wear patterns to reduce downtime and costs.
• Flexible Formats: Technical manuals, video tutorials, or remote training by engineers to meet diverse needs.

Technical Support Commitment

• Response Time Commitment: urgent issues resolved within 2 hours, general inquiries within 24 hours.
• Multi-channel support: phone, email, WeChat, WhatsApp, video call.
• Priority handling for urgent faults: solution provided within 2 hours to minimize downtime.
• Regular follow‑ups and continuous optimization suggestions for stable equipment operation.

Frequently Asked Questions (FAQ)

Proactively answer technical questions: We proactively provide professional answers and suggestions for common issues such as material selection, installation and commissioning, and maintenance cycles, reducing customer concerns and improving cooperation efficiency.

Q: What's the production process of crusher wear parts?

A: Pattern/Mold Making, Molding and Casting, Shakeout and Cleaning, Heat Treatment, Machining and Finishing, Quality Control and Inspection, Painting and Marking, Packaging and Shipping.

Q: How to choose the correct blow bar material?

A: The decision is made based on the crusher model, material type, hardness, feed size, and the material to be crushed. ONA's professional engineers can also recommend the most suitable material.

Q: What's the penetrant testing in crusher wear parts?

A: Penetrant testing. also known as lquid penetrant testing, is a non-destructive testing method widely used in industrial fields such as casting and forging. Its main function is to detect surface defects in mantle and concave, and other wear liners.

Its core principle is very simple and intuitive: It utlizes the capillary action of liquids to detect discontinuous defects with openings on the material surface, such as cracks, pores, and porosity.

All names, marks, models, symbols and descriptions are used for reference purposes only and it is not implied that any of the parts/brands listed are the product of any company other than ONA. We are not agents or distributors for any of the above mentioned brands nor do we have any commercial relationship or association with them.
