Bucket elevators (noria) is a vertical conveyor designed for transporting various bulk, granular and lumpy materials in a vertical direction The widespread use of bucket elevatorselevators in various industrial sectors is due to the significant advantages of the equipment, which makes it possible to move cargo to a considerable height with a wide range of productivity and compactness of the installation (small dimensions in the cross section). The closed body of the equipment ensures the safety of the transported cargo and protection of the environment from pollution, and the simplicity of the noria design guarantees high reliability in operation and ease of adjustment. As lifting and transport equipment, a noria or a bucket elevator has the lowest specific operating and energy costs, the price of which is directly involved in the formation of the cost price and the final profit of the activity as a whole.
