Conveyor belts are often made rough to enhance their grip and prevent materials from slipping during transport. In heavy industries such as mining, the rough texture is crucial for effectively moving materials like ores, coal, and aggregates, which can be heavy and abrasive. The rough surface increases friction between the belt and the materials, ensuring stable and controlled movement, especially on inclines or declines. This texture also helps in the efficient transfer of materials to and from different sections of the conveyor system, reducing spillage and maintaining a steady flow. Additionally, the rough surface can assist in cleaning the belt by dislodging debris and preventing material buildup, thereby reducing maintenance needs and prolonging the belt's lifespan.
