Pipe Conveyor ensures dust-free transportation of ore concentrates

Transportadora Callao S.A. relies on a BEUMER Group Pipe Conveyor for the transportation of zinc, copper and lead concentrates of different mining companies from the warehouse to the terminal.

Transportadora Callao S.A. is a logistics operator of a special cargo terminal in the port of Callao/Peru. Callao is located directly on the Pacific Ocean. With 877,000 inhabitants, it is one of the largest cities of Peru, with the largest airport in the country and one of the most important fishing and commercial ports in South America

The pipe conveyor has the ability to navigate curves in three dimensions, the conveyor can be optimally adapted to its routing course of approx. 3000 metres. What is even more important: the conveying system prevents the concentrates from coming in contact with the environment and ensures dust-free transport to the ship's holds. BEUMER Group was responsible for engineering and supply, including the steel structure, supervision of the installation and putting the Pipe Conveyor into operation.

Pipe Conveyor: dust-free conveying

The mines in central Peru transport their concentrates to the warehouses, approx. 3 kilometres from the port. This required an absolutely protected method for the transportation of material, to prevent particle emission into the atmosphere. Transportadora Callao opted for the BEUMER Group Pipe Conveyor. The direct contact person and project partner was Helmut Wolf from BEUMER Group Austria GmbH: "Together with the responsible persons from the customer, we developed a solution that is perfectly adapted to the routing and the ambient conditions."

Due to its enclosed transport, the Pipe Conveyor not only protects the environment against harmful impacts during the transport of the lead concentrate, it also allows conveying over long distances and navigation through tight curve radii. Due to its ability to navigate curves, this belt conveyor requires a lot less or no transfer towers at all, depending on its length and the available curve radii. This results in substantial cost savings for the customer, and allows BEUMER Group to easily customise the system to the individual routing. Durable conveyor belts guaranteeing tensile strength are used. The engineers use different dimensioning programs to determine the ideal belt design. They use them to calculate tractive forces and forces that arise during acceleration and deceleration and also to determine possible curve radii. BEUMER Group provides tailor-made feasibility studies for each project. Another advantage is the reduced noise emission that the system provides. This is ensured by special idlers, as well as low-noise bearings and selecting the right conveying speed. "This improves the quality of the employees' day-to-day work environment," says BEUMER engineer Wolf. Victor Sams adds that the "noise measurements along the Pipe Conveyor resulted in values that are consistently far below the permitted limit values."

Conveying capacity: 2,300 tons per hour
