Haihui Environmental Protection Equipment Co., Ltd. manufactures durable belt conveyor carry trough idlers under the Haihui brand. These idlers are installed on the carrying side of belt conveyors to support the belt and transported material. The trough angle is available at 20, 35, or 45 degrees to suit different load capacities and material types. Made from high-quality steel tubes and sealed bearings, our idlers offer low rotational resistance and long service life. Each idler undergoes rotation resistance testing, radial runout inspection, and seal integrity checks before shipment. Haihui provides reliable, cost-effective idler solutions for mining, cement, and aggregate industries. Custom sizes and coatings are available.
