Conveying & Loading - Dust free!

Environmental Protection along the complete Transport Chain
Dust is one of the real big problems in bulk handling. It means loss of product, pollution of the environment, and trouble with the neighbours. Solutions for some of this problems are presented hereafter.

With the Beumer bulk loading head, bulk transporter vehicles can be loaded quickly and without dust.

Beumer Group is a world-leading systems provider for transporting, loading, filling and packaging bulk material. Their  portfolio includes curved belt conveyors for fast and cost-efficient transport of large quantities of bulk material from the quarry or mine to the factory or port. The belt conveyors are able to navigate long distances, high angles of inclination and tight curve radii, and can be adapted individually to the belt or pipe conveyor bulk handling solutions. Depending on the customer’s requirements, Beumer provides either troughed belt or pipe conveyor bulk handling solutions. Open troughed belt conveyors are recommended for larger throughputs, higher mass flows and wider curved radii. Closed Pipe Conveyors protect both transported items from environmental influences and the environment from falling items. Troughed belt conveyors can also be covered or encased to minimise dust formation during transport. This seal guarantees dust-free transport.

Beumer’s portfolio also includes mechanical vertical conveyors such as belt bucket elevators. They are an essential production link in the cement industry. Beumer reliably seals the shaft casings of these bucket elevators, which stops dust from escaping. Instead, the dust trickles into the bucket elevator boot that is equipped with a dynamic bottom. Wet and sticky material cannot accumulate but is fed back into the transport process.

Loading without Spilling

The Beumer Group has developed bulk loading heads for the quick and dust-free loading of bulk transporter vehicles. They are designed according to the double-wall system, where the material inlet and the dedusting unit are separated from each other. When the bulk loading head is placed on a filler neck, its sealing cone is lowered and the outlet spout opens simultaneously. The lowering level of the sealing cone is variable. You can adjust the fill level in the vehicle using the fill level meter. In order to balance out any minor positional deviations of the vehicle, the operator can move the bulk loading head laterally during placement.

The bulk loading head is also available with an integrated filter allowing you to operate the centralised dedusting units independently from the dust transporting devices. The dust removed from the bulk transporter vehicle is fed again to the material flow during loading. The filter consists of filter hoses which are positioned between the inner telescopic tube and the outer bellows. The suction is carried out by a fan fastened at the outside. The cleaning is carried out by timed compressed-air shocks.

Dust-free Loading of Open Vehicles

Beumer offers various types of telescopic loading systems for dust-free loading of open vehicles. With these systems, the bulk loading head is lowered to the floor of the vehicle and the material feed is switched on. A fill level switch in the lower dedusting hood is activated by the rising material. This causes the bulk loading head to be raised automatically. The edge of the dedusting hood always rests on the material cone while it rises, so that no dust can escape. The bellows, or the telescopic tubes for the dust extraction, are connected to a central dedusting air system. Corresponding devices or flow control gates transport the material to the system. The bulk loading heads can also be equipped with fill level indicators. Once the vehicle is loaded, they reliably turn off the material feed. Different types of fill level indicators are used depending on the properties of the material.
