Roll Tooth Liner – Toothed Segments, Wolf Teeth Liners, Roller Wear Plates

Introduction

Double toothed roll crushers are widely used for primary and secondary crushing. They can process coal, coal gangue, limestone, construction waste, ore and sticky bulk materials,When the machine runs continuously, materials are squeezed, cut and hit between two rollers turning in opposite directions. This leads to heavy wear on roller parts,If the Roll Tooth Liner wears seriously or breaks, the crushing ability will fall quickly. The output material size cannot be controlled, and unexpected machine stops will cause economic losses.

Saikuang Machinery supplies OEM replacement Roll Tooth Liners for most common double toothed roll crushers.Our main products include Wolf Tooth Liners, Square Tooth Segments, Wave Tooth Roll Liners, Integral Roll Tooth Plates and Segmented Tooth Liners.

We have developed top grade High Chrome + Ceramic Composite Roll Tooth Liners as our improved material solution. This product has excellent wear resistance. Its service life is 2–4 times that of standard high manganese steel roll tooth liners.

All parts are made strictly according to original equipment drawings. Customers can install them directly. No cutting or changes are needed.

Main Roll Tooth Liner Types

1. Wolf Tooth Roll Tooth Liner

Wolf tooth liners are the most widely adopted wear parts for heavy-duty toothed roll crushers. Sharp wolf tooth structures deliver strong biting and splitting force for large lump raw materials, reducing over-crushing and powder generation. We manufacture wolf tooth liners with three material grades: standard Mn14/Mn18 high manganese steel, regular 26% high-chrome alloy, and premium high chrome + ceramic composite. Our high chrome ceramic composite version balances toughness and ultra-high abrasion resistance, perfectly solving rapid tooth wear issues under long-term continuous crushing.

2. Square Tooth Roll Tooth Liner

Square tooth liners feature thick, block-shaped teeth with strong anti-abrasion performance, designed for medium-hard and highly abrasive materials like limestone, silica ore and coke. Uniform tooth layout ensures stable finished aggregate grading. For high-abrasion silica and quartz mines, our high chrome + ceramic square tooth liners are the top pick, far outperforming common manganese steel liners in service life. Our square tooth liners adopt precision casting technology, consistent tooth thickness and spacing, effectively avoid partial wear and material blockage.

3. Wave Tooth Roll Tooth Liner

Wave tooth liners are specially customized for sticky, high-moisture materials such as wet coal, clay-containing gangue. Curved wave tooth surface prevents material adhesion and blocking inside the crushing chamber. We supply solid high manganese wave tooth liners and reinforced high chrome ceramic composite wave tooth liners, suitable for long-term continuous operation in coal washing plants with heavy abrasive feed.

4. Segmented Split Roll Tooth Liner

Segmented split tooth liners are modular bolt-fixed design, only worn single segments need replacement instead of full roller liner, greatly cutting maintenance time and spare parts cost. All split liners come with standard mounting holes, perfectly matched with original roller body installation positions. We offer split liners in high chrome ceramic composite material to extend replacement intervals significantly.

5. Integral Full Roll Tooth Liner

Integral roll tooth liners are one-piece casting for small & medium toothed roll crushers, easy for overall disassembly and installation, ideal for fixed crushing stations with low frequent replacement demands. Both manganese steel and high chrome ceramic composite material options are available.

Advantages of Saikuang Machinery Roll Tooth Liner

1. 100% Direct OEM Replacement Parts All Roll Tooth Liners are reverse-produced based on original drawings and sample measurements. Standard mounting hole positions, tooth height and radian fully match original rollers, no on-site cutting, welding or adjustment required during installation.
2. Multi-Grade Wear-Resistant Material Options, High Chrome + Ceramic Composite As Flagship Upgrade We provide three core material systems to match different working conditions, with our proprietary high chrome + ceramic composite as the top performance solution:

• Mn14/Mn18 high manganese steel: Outstanding impact resistance, self-work-hardening surface, suitable for large lump hard rock crushing; Baseline service life reference
• 26% high-chromium alloy: High surface hardness HRC 58–62, excellent anti-abrasion performance for medium-hard ore and aggregate;
• High Chrome + Ceramic Composite (Core Highlight): Ceramic particles embedded uniformly inside high-chrome matrix via special metallurgical casting process. The ceramic phase delivers ultra-high hardness up to HV2000+, while high-chrome substrate maintains anti-crack toughness. Its service life reaches 2–4 times that of ordinary manganese steel liners, drastically reducing replacement frequency, machine downtime and comprehensive tonnage cost. Perfect for high-abrasion silica, quartz, coal gangue and long-cycle continuous production lines.

3. Strict Multi-Process Quality Inspection All cast tooth liners go through heat treatment, metallographic analysis, hardness test and ultrasonic flaw detection to eliminate internal pores, shrinkage cavities and hidden cracks. Precision CNC machining guarantees tight dimensional tolerance and stable assembly. Our high chrome ceramic composite liners pass extra bonding strength inspection to avoid ceramic peeling during operation.
4. One-Stop Complete Roller Wear Parts Supply Besides Roll Tooth Liner, we also supply roller end liners, scraper wear plates, roller shaft sleeves and other matched spare parts for double toothed roll crushers, satisfying one-time bulk purchasing demand from mine and aggregate clients.

Why Choose Roll Tooth Liner From Saikuang Machinery?

Frequent equipment shutdown caused by worn or cracked roll tooth liners brings huge losses to production output. Ordinary manganese steel liners wear rapidly under abrasive materials, requiring frequent replacement and raising overall operation cost. Choosing our premium high chrome + ceramic composite Roll Tooth Liner effectively extends service life to 2–4 times of standard manganese steel products, reduces maintenance frequency and improves overall equipment operation rate.

Saikuang Machinery specializes in full-series crusher wear-resistant casting spare parts including VSI wear parts, cone liner, jaw plates and Roll Tooth Liner. We accept small trial orders and large framework bulk orders with flexible delivery cycles. Contact our sales team to get latest quotation for all types of toothed roll tooth liners, especially our high chrome + ceramic composite upgraded model.
