Pfister® Rotor Weighfeeder upgrades and spare parts

Key Benefits

Increased alternative fuels substitution
Lower production and maintenance costs
Improved equipment performance
Consistent and reliable feeding, guaranteed

Even the best technologies have rooms for improvement. We have identified the routes to optimised performance and lower maintenance with our DRW rotor weighfeeders. Even just one could have a big impact on your process – and your costs. Are you ready to make the small change that makes a big difference?

Rotor Weighfeeder upgrades that lower costs and increase efficiency

When it comes to performance, consistent and reliable dosing is crucial. But it’s not the only factor affecting your process – inefficiencies have a big part to play. That’s why we continue to work on upgrades to our DRW Rotor Weighfeeder, which is now available with a series of optional enhancements to optimise performance.

Four new developments offer the potential to increase the performance and reliability of your dosing equipment.

FEEDflex™: A low-cost solution to drastically reducing coal use while increasing AF. Paving the way to MISSION ZERO

PFISTER® FEEDflex is part of our strategy to support customers’ sustainability targets. It enables you to dose very small quantities of pulverized fuel pulsation-free down to 60 kg/h and without CO spikes.

This solution doesn’t affect the maximum feed rate your DRW feeder currently achieves. You can still use it up to its maximum capacity as required in the kiln start-up.

This small upgrade can have a significant impact. Adding FEEDflex techology to your Pfister® DRW Rotor Weighfeeder enables you to operate with very low coal feed rates (in the range of 1:100 pulsation free dosing) while increasing your use of low-cost, environmentally friendly alternative fuels. The investment pays off in a very short time. Get the brochure here

AutoGAP 2.0: Increase productivity and reliability, reduce maintenance and wear - all by simply controlling the gap witdth

The gap width of your PFISTER® DRW rotor weighfeeder has the potential to make or break your operations. Too small and you risk blockages. Too large and feeding accuracy is impeded – not to mention the increased wear that threatens equipment life. The gap width has to be just right.

The PFISTER® AutoGAP 2.0 eliminates the need for trial and error. It automatically adjusts and controls the upper gap width, ensuring the best possible performance of your DRW rotor weighfeeder. Three distance sensors measure and adjust the gap between the upper and lower housing during feeder operation. The motor current is also monitored constantly to support the quick-open function.

You can opt for this system to be supplied with Wi-Fi dashboard to monitor equipment performance, including motor current, speed, GAP position, and to set new parameters on your Smartphone. Get your brochure here

Your predictive maintenance becomes far easier – particularly when the system is used in combination with the Pfister® Wear Index

Central Stirrer upgrade for pre-hopper

The new accordion stirrer optimizes the pneumatic conveying of the coal dosing process and ensures a stable material flow from the coal silo to the dosing point at the kiln or calciner.

Kit of sealing plates gasket for easy and safe substitution of process fluids

Chemical consumables like the process fluids are required in the cement industry and its production equipment. But with the new PFISTER sealing plates gaskets the replacement is easier and faster. No mix-up of improper sealing material and no mistakes during the removal.
