FEEDflex™ upgrade

The road to Net Zero is long, but the cement industry is already making headway.

Fuel switching and energy-saving measures have enabled cement plants to bring down carbon emissions. And though it is tempting to think that the biggest changes are brought about in the largest equipment, the smaller machinery also has a part to play.

PFISTER FEEDflex is our contribution to a more sustainable future

The PFISTER® DRW Rotor Weighfeeder has been serving the cement industry for decades, providing efficient, reliable, and precise dosing of pulverised fuels such as hard-coal, lignite, or petcoke.

As the use of alternative fuels (AF) increases, fuel feeding systems that offer more highly variable feed rates are needed. But as AF use increases, there is a need for ever smaller feed rates in primary fuel feeders, which has been an obstacle for cement producers trying to maximise fuel substitution.

Our feeding experts have developed a solution to this problem, by significantly reducing the feed rates of the PFISTER DRW Rotor Weighfeeder without limiting the maximum possible feedrate.

Minimising coal consumption

The maximum feed rate is unaffected, so when you need to increase coal consumption – at kiln start-up, for example, or if AF supplies are low – you can do so. FEEDflex™ gives you the flexibility to operate with very low coal feed rates in the max. feed range of 1:100 pulsation free dosing and the scope to increase the use of low-cost, environmentally friendly alternative fuels.
