ZZ Craftsman Secondary Belt Carbide Cleaner for Mining Conveyor Return Side

The ZZ Craftsman Secondary Belt Carbide Cleaner (also referred to as ZZ Old Craftsman or from Zhuzhou OC Precision Alloy Co., Ltd.) is a heavy-duty secondary conveyor belt cleaner designed specifically for demanding applications like mining operations. It uses tungsten carbide (carbide-brazed) blades or tips for exceptional wear resistance, durability, and cleaning performance on conveyor belts handling abrasive materials such as ore, coal, aggregates, or minerals.

Based on the information from the manufacturer, ZZ Old Craftsman, here is a detailed breakdown of this product and its capabilities.

🎯 What It Is: A High-Performance Secondary Cleaner

The “ZZ Craftsman Secondary Belt Carbide Cleaner” is a scraper blade system specifically engineered for installation on the return side of mining conveyor belts -3 -7. Its primary job is to act as a secondary cleaner. Positioned after the primary cleaner (near the head pulley), it removes the fine particles and sticky residue that the first cleaner missed, ensuring the belt is thoroughly clean before it cycles back -3 -8.

🛠️ Key Features and Technical Specifications

The cleaner’s performance is built on advanced materials and manufacturing.

Material Composition: The blade tips are made from tungsten carbide, one of the hardest materials available, brazed onto a stainless steel body. This combination provides extreme wear resistance at the cleaning edge and toughness in the support structure -2 -7.
Manufacturing Process: ZZ Old Craftsman uses vacuum brazing technology to bond the carbide to the steel. This process creates a seamless, high-strength bond without weak points, leading to a longer-lasting and more reliable product compared to older methods like induction welding -5 -7.
Hardness: The carbide tips achieve a hardness of up to 92.5 HRA (Rockwell Hardness A) -7. For context, this is significantly harder than steel, which typically ranges from 60-70 HRA -2.
Service Life: Due to its extreme hardness, the scraper boasts a service life 3 to 5 times longer than standard induction-welded scrapers -7.
Temperature Adaptability: It is designed to perform reliably in extreme environments, with an operating temperature range of -40°C to 300°C -7.

⛏️ How It Solves Mining Conveyor Challenges

Mining conveyors face unique problems, and this cleaner is designed to address them head-on -7:

Problem: High Abrasion – Mining materials like iron ore, coal, and copper are highly abrasive and quickly wear down standard scrapers.
- Solution: The tungsten carbide blade has extreme wear resistance, resisting this abrasion and maintaining a sharp edge far longer.
Problem: Material Carryback – Sticky residues left on the belt increase energy costs, require manual cleanup, and can damage rollers.
- Solution: By aggressively removing fine and sticky particles, the secondary cleaner drastically reduces carryback, improving efficiency and reducing costs -8.
Problem: Frequent Downtime – Constant scraper failures halt production and impact profitability.
- Solution: The long service life minimizes the need for replacements, leading to reported outcomes like up to 40% savings in maintenance costs and 25% less downtime -7.

📐 Available Types and Customization

ZZ Old Craftsman produces several standard shapes for their scrapers, each suited for different applications -7:

P Type: Designed for high-abrasion environments, such as iron ore processing on wide belts.
H Type: Features a reinforced structure for high-impact applications like coal transportation.
R Type: Offers precision and adaptability, often used in compact systems like underground conveyors.

Crucially, all these types can be fully customized. The company can tailor the scraper’s size, shape, and configuration to match your specific conveyor’s belt width (from 650mm to 2400mm), belt speed, and the type of ore being handled -2 -7.
