DISTRIBUTION SYSTEMS FOR CONTROLLED ALTERNATIVE FUELS AND RAW MATERIALS FEEDING

Reliable material distribution systems for alternative fuels and raw materials (AFR), designed to stabilise material flow, ensure consistent extraction and support controlled feeding across cement, lime, waste processing and energy facilities.

STABLE DISTRIBUTION FOR CONSISTENT MATERIAL SUPPLY

AFR distribution and pre-feeding form the link between upstream conveying or storage and downstream feeding systems. At this stage, bulk materials are buffered and released in a controlled manner to one or multiple conveyor lines, ensuring a stable and continuous supply.

Material received from upstream systems is temporarily stored in distribution bins, where it is stabilised before being discharged via screw conveyors at a consistent rate. This stage helps balance fluctuations in supply and demand while maintaining a steady material flow to the next stage of the fuel handling process.

Ensuring consistency and control, AFR distribution systems support overall process stability and efficiency.

CHALLENGES IN ACHIEVING CONSISTENT MATERIAL DISTRIBUTION

  • Fluctuating upstream or downstream conditions

    Variations in supply or demand can create unstable feeding conditions and reduce system reliability.

  • Irregular material flow from storage

    Variations in bulk density, moisture or particle size can lead to unstable flow behaviour and inconsistent extraction.

  • Bridging and rat-holing

    Poor flow conditions inside distribution bins can restrict discharge and interrupt downstream material supply.

  • Uneven discharge across extraction points

    Inconsistent material withdrawal can result in fluctuating feed rates and uneven loading of downstream equipment.

  • Loss of controlled material supply

    Inadequate distribution can reduce the efficiency of downstream handling systems, affecting overall system performance

CONSISTENT MATERIAL FLOW THROUGH SCREW-BASED EXTRACTION

Bulk material distribution systems must do more than buffer material – they must actively control how it is discharged.

Screw-based extraction provides a reliable way to stabilise material flow within the bin and ensure consistent discharge. Unlike gravity-driven systems, screw conveyors deliver positive extraction, preventing bridging and ensuring uniform material withdrawal.

By adjusting screw speed, these systems enable precise feed rate control, supporting consistent downstream feeding even when material properties or upstream supplies fluctuate. Their enclosed design also helps minimise dust emissions and maintain safe, clean operation.

This combination of controlled extraction, flow stability and operational reliability makes screw-based systems particularly well suited to alternative fuels distribution, where materials are often variable, cohesive or difficult to handle.

BEUMER DISTRIBUTION SOLUTIONS FOR PRECISE AND RELIABLE FEEDING

BEUMER Group designs material distribution systems tailored to the specific material characteristics and process requirements of each application.

We consider factors such as material behaviour, bulk density, moisture content, required feed rates and system layout to develop a distribution solution that ensures consistent extraction and stable downstream feeding. This system-level approach helps maintain reliable operation despite fluctuating supply conditions and the varying characteristics of alternative fuels.

Screw-based technology forms a key part of these solutions. Depending on the application, BEUMER configures distribution systems different outlet or screw configurations to achieve the required level of control and flexibility. For example, the BG OptiBin D can be configured with two or four outlets using double- or single-screw arrangements moving in the same or opposing directions, while the BG OptiBin SB is designed for controlled distribution via two single-screw outlets working in opposite directions. These systems can be customised further to meet specific AFR distribution requirements.

By combining proven technologies with application-specific engineering, BEUMER Group delivers alternative fuels distribution systems that ensure consistent material flow, precise feeding and reliable long-term performance.
