Weba Chute Systems recently completed a project for an Iron Ore mine in Postmasburg, Northern Cape, South Africa, involving the supply of a conveyor to conveyor transfer chute. The client was concerned about degradation, spillage, and uneven belt loading due to the material specifications, which included bulk density of 2.6t/m³, lump size of 31.5mm, dry material, and a maximum throughput of 1400 tons per hour.
The success of the project can be attributed to Weba Chute System's scientific approach to the dynamics of bulk materials handling. Each system is custom-designed, taking into account all factors such as belt speed, width, material size, shape, and throughput to control the direction, flow, and velocity of the material. The streamlined approach significantly reduces dust and ensures the absolute control of material during transfer, eliminating degradation.
Mark Baller, Managing Director at Weba Chute Systems, explains that controlling the transfer of material onto the conveyor belt is key to eliminating degradation, requiring an in-depth understanding of how material needs to be transferred and factors in changes of direction, impact, and height of transfer. The system's geometry must move material through the chute with gradual directional changes and controlled velocity to minimize impacts that lead to degradation and dust generation. Additionally, discharge onto the conveyor system must be correctly controlled and as close to the belt speed as possible.
The system's success was evident during a 3-month inspection, during which no spillage or wear were reported. Controlling the transfer of material onto the conveyor belt guarantees increased cost savings for clients, in addition to improved health and safety performance. Weba Chute Systems incorporates transfer chutes that have been custom-designed and engineered to suit specific applications, with optimized plant design that considers each element within the process flow. This global best practice ensures that each Weba Chute System is designed to maximize efficiency and reduce maintenance costs.
