Improve belt conveying Speed with low noise
The Lan Hua stone roller features high machining precision, outer diameter radial runout of only 0.18 mm. This enables high-speed operation, increasing belt speed to over 7 m/s – significantly enhancing conveying capacity – while also reducing operational noise.
Insulating, no static electricity generation, Self-lubricating, No sharp edges will form that could cut or damage the belt
Lan Hua Stone is a special material. No static electricity while contatcing with the belt; Non attract dust particles. After 27 days of continuous friction between the stationary Lan Hua roller and the conveyor
belt, the self-lubricating property ensures that no sharp edges are formed and no sparks are
generated, providing a significant safety guarantee for production operations.
High Load Capacity , Cost Reduction
The Lan Hua stone roller offers high load-bearing capacity, with a compressive strength of 297 MPa/cm² when combined with a steel tube. This enables down-sizing applications – for example, replacing φ108 mm rollers with φ89 mm rollers to reduce procurement costs.A specialized adhesive technology ensures a precise bond between
the Lan Hua stone and the steel tube,significantly enhancing the roller's load capacity. Its thermal expansion coefficient is perfectly matched to both the steel tube and the stone substrate.
