Skirted conveyor belts (also known as corrugated sidewall conveyor belts) are specialized conveyor belts designed specifically to address the challenges of conveying bulk materials (such as ore, coal, grain, and sand and gravel) at steep angles and prevent leakage. Based on a conventional flat conveyor belt, they feature vertical "skirts" (sidewalls) added to both sides of the belt through a vulcanization process. Horizontal "partitions" are placed between the skirts, creating a closed conveying space similar to a "hopper." This overcomes the limitations of conventional conveyor belts (maximum inclination angle ≤ 18°) and enables conveying at steep angles of 30°-90° (vertical), while preventing material spillage and leakage. Widely used in industries such as mining, coal, grain, building materials, and chemicals, they are particularly well-suited for applications where space is limited and high-drop material transfer is required. They are key equipment for shortening conveying distances and reducing infrastructure costs.
