Tungsten carbide peg details:

FAQ for tungsten carbide pegs:

Q1: What are tungsten carbide pegs?

A: Tungsten carbide pegs (also known as carbide stirring pins or grinding pins) are wear-resistant agitator components mounted on the rotor of horizontal bead mills / sand mills. They agitate grinding media and disperse pigments, inks, coatings, and slurries. We supply both solid integral carbide pegs and brazed pegs (carbide head + steel shank).

Q2: What is the difference between integral solid carbide pegs and brazed pegs?

A: (1) Integral solid carbide pegs: Entirely tungsten carbide, no braze seam – thus zero risk of head detachment (though extreme shock may cause brittle fracture). Offers the longest service life due to the entire peg body being wear-resistant, providing significantly more usable wear length. Higher cost, requires careful thread anti-seize during maintenance.

(2) Brazed pegs: Tungsten carbide head brazed onto a steel (often carbon steel) threaded shank. Cost-effective, with tough steel threads that are easy to remove. The steel shank absorbs impact well, but under thermal/mechanical fatigue or extreme impact, the braze joint may crack or the head may detach.

Recommendation: Brazed pegs are the industry standard for general sand mill applications. For high-output, premium long-life operations where downtime is expensive, solid integral pegs are the superior choice.

Q3: What dimensional tolerance can you achieve?

A: Outer diameter tolerance of ±0.002 to ±0.01 mm. Threads follow standard metric tolerances. All finished pegs are precision ground.

Q4: How long is the service life compared with steel pegs?

A: Tungsten carbide pegs typically last 5–12 times longer than hardened steel pegs, significantly reducing machine downtime and replacement frequency. Actual lifespan depends on grinding media type, slurry abrasiveness, and rotation speed.

Q5: How do you control quality before delivery?

A: Each batch is subject to a comprehensive outgoing inspection that includes the following 11 items: chemical composition (WC and Co content), density, coercive force, transverse rupture strength, metallographic structure (grain size and binder phase distribution), porosity rating, dimensional and thread geometry, concentricity/run‑out (especially critical for brazed pegs), hardness (HRA), surface condition (freedom from cracks, pores, and burrs), and braze joint integrity (for brazed types only). Through these strict inspections, we ensure that no non‑conforming products are ever shipped out.

Q6: What’s the minimum order quantity (MOQ)?

A: Standard stock sizes normally require 5kg MOQ. Non-standard customized shapes require higher MOQ to cover mold & sintering cost.

Q7: What’s your production lead time?

A: Stock carbide pegs: 2–3 working days.
Standard carbide pegs: 10–25 days.

Details of carbide gripper inserts:

FAQ for carbide grippers:

Q1: What are carbide grippers?

A: Industrially known as cemented carbide slip inserts, carbide grippers are sintered tungsten carbide-cobalt components (tungsten carbide matrix bonded with cobalt binder). Their surfaces are precision-machined with anti-slip serrated teeth, and most variants are silver-brazed onto a 45# or 40Cr steel substrate. Relying on their ultra-hard, wear-resistant tooth profiles, they clamp drill pipes, casings, metal bars and shaft workpieces. They are divided into three core application types: slips for oilfield wellheads, chuck jaws for CNC lathes, and gripping inserts for automation robotic grippers.

Q2: How to select carbide grippers grade and their applications?

A: For YG-series carbide: higher cobalt means better toughness and impact resistance; lower cobalt means higher hardness and better wear resistance.
YG6: Low cobalt, HRA 90–91, high wear resistance. Suitable for light-load, impact-free smooth clamping pads; not for toothed load-bearing slips.
YG8: General-purpose balanced grade. Ideal for standard oilfield drill pipe slips and common steel pipe clamping. It is the most widely used grade.
YG8C / YG11C: Coarse grain, high toughness. For heavy-duty drilling, burr workpieces and frequent impact clamping, anti-chipping performance is excellent.
YG13C / YG15: High cobalt, maximum impact resistance. Used for large drill collars, downhole packer anchors and heavy mining clamps to prevent tooth breakage under severe impacts.

Q3: Do you support non-standard customization of carbide grippers?

A: We support customization based on provided drawings or samples; customers must supply complete specifications:

Q4: What’s the minimum order quantity (MOQ)?

A: Standard stock sizes normally require 3kg MOQ. Non-standard customized shapes require higher MOQ to cover mold & sintering cost.

Q5: What is the production lead time for carbide grippers?

A: In-stock carbide gripper inserts: 2–3 working days.
Standard custom orders: 10–25 working days.

HPGR studs sizes：

Tungsten carbide studs for HPGR details:

FAQ for HPGR studs.

Q1: What are HPGR studs?

A: HPGR studs are high-strength tungsten carbide pins embedded into the surface of HPGR roller sleeves. Featuring standard domed heads (optional flat tops), they form a stable self-generated autogenous material bed during operation, protecting the roller base from direct abrasion and enabling efficient inter-particle compression crushing for minerals, cement raw meal and limestone.

Q2: What are the advantages of studded rollers over hard faced welded rollers?

A: First, 10 times longer service life under identical working conditions. Second, significantly reduced downtime, as only individual damaged studs require replacement instead of full roller reconditioning. Third, consistent roller gap and uniform product granularity throughout the entire service cycle. Fourth, superior impact and fatigue resistance for harsh feeding conditions.

Q3: What tungsten carbide grades are available for HPGR studs?

A: We supply application-optimized grades aligned with Chinese GB standards:

(1)YG11: High wear resistance for limestone and cement raw meal (low abrasion, extended life).
(2)YG13: Balanced toughness and wear resistance for iron ore and gold ore (medium impact).
(3)YG15/BTD15: High-toughness grade: Maximum impact resistance for heavy-impact sites with oversized rocks and tramp metal.
Ultra-fine grain grade: Premium abrasion resistance for highly abrasive bauxite and hard minerals.

Q4: How do cobalt content and WC grain size affect the wear resistance and strength of HPGR studs?

A: (1) Hardness/Wear Resistance: Lower cobalt content and finer WC grains result in higher hardness and wear resistance; conversely, increasing cobalt content or grain coarsening leads to reduced hardness.
(2) Fracture Toughness: Coarser WC grains result in better fracture toughness.
(3)Transverse Rupture Strength: Coarse-grained material exhibits higher strength when cobalt content is below 12%; however, for grades typically used in cement grinding (where cobalt content exceeds 15%), fine-grained cylindrical inserts demonstrate superior transverse rupture strength compared to coarse-grained ones.

Q5: What is the optimal grade of HPGR studs for high-severity cement raw material processing conditions, and what is the basis for this choice?

A: The preferred choice is YG15 (medium-to-fine grain), followed by YG13. This is based on a 130-day comparative test using the same roller: YG15 fine-grain studs exhibited low wear rates and no cracking or edge chipping, while offering sufficient flexural strength—perfectly balancing wear resistance with toughness. In contrast, YG11 offered the best wear resistance but had low cobalt content and poor impact resistance, making it prone to breakage when processing large material chunks; YG16 and YG18 lacked sufficient wear resistance, and coarse-grain grades showed excessively high failure rates.

Q6: What is the typical service life of HPGR studs?

A: (1)Cement raw meal & limestone: 20,000–30,000 operating hours.
(2)Magnetite & hematite ore: 8,000–12,000 operating hours.
(3)Gold ore & bauxite: 5,000–8,000 operating hours.
Actual service life depends on ore abrasiveness, feed size distribution, roller pressure and tramp iron removal efficiency.

Q7: Do you support customized sizes and grades?

A: Absolutely. As an experienced HPGR studs manufacturer based in China, we offer full customization covering diameter, total length, head shape (domed/flat) and alloy grades, all tailored to each customer’s specific ore types and operating conditions.

Q8: What is the standard lead time?

A: Standard sizes (Φ16, Φ20, Φ25 mm) are in stock with 3–7 days delivery. Custom non-standard studs require 15-20 working days for production.
