Diamond-Shaped Cold Adhesive Sheet
- Cold adhesive bonding technology — no vulcanization equipment or factory processing required, enabling fast on-site installation with minimal downtime;
- Raised diamond-pattern surface delivers superior grip on drive pulleys, preventing belt slippage and reducing lateral deviation under load;
- High-density rubber compound with excellent elasticity and anti-adhesion properties, resisting material buildup on the pulley surface in dusty and wet conditions;
- Service life several times that of conventional cast rubber lagging, significantly reducing replacement frequency and long-term maintenance cost;
- Cost-effective alternative to flat rubber sheets — widely adopted across coal mining, ports, metallurgy, and power generation for reliable drive pulley protection.
Product Introduction
Diamond-shaped cold adhesive sheets are specifically designed for lagging on drive pulleys in belt conveyor systems. The raised diamond-pattern surface creates consistent, high-friction contact between the pulley and the conveyor belt, preventing material buildup on the drum surface and significantly reducing the risk of belt deviation during operation.
Compared to flat rubber lagging sheets, diamond-shaped sheets offer superior grip geometry and better self-cleaning characteristics — making them one of the most widely adopted and cost-effective pulley lagging solutions across the bulk material handling industry. For operations that need reliable performance without the lead time and cost of hot vulcanization, this is the practical, proven choice.
On-Site Cold Bonding Installation
No vulcanization equipment needed. Fast field application with minimal conveyor downtime.
Superior Grip Through Diamond Geometry
A raised profile that prevents slippage, resists material buildup, and supports belt tracking.
Product Structure & Working Principle
From surface grip to bonding interface — how every layer of this sheet earns its place.
Diamond-Profile Surface Layer
The outermost layer of the sheet features a precisely formed diamond-pattern profile across its entire surface.
High-Density Rubber Compound Body
Beneath the diamond surface layer sits the main rubber body, formulated from a high-density compound with high elasticity and strong anti-adhesion characteristics.
Cold Adhesive Bonding Interface
The underside of each sheet is prepared for cold adhesive application, achieving a rated adhesion force of 12.6 N/mm between the lagging sheet and the pulley drum surface.
How It Corrects Belt Deviation
Belt deviation most commonly originates or worsens at the drive pulley, where tension and friction forces are highest.
