Precise, reliable dosing of fine-grained and powdered materials
Gravimetric feeding and dosing. Accurate and easy to operate.
When it comes to precise processes like cement manufacturing, the accuracy of your feeding and dosing systems is crucial. The strength of the final product is dependent on getting the mix just right. And it’s not just product quality at stake. When dosing is not consistent, the efficiency and profitability of your process is also impacted. The PFISTER FRW Rotor Weighfeeder is designed for highly accurate gravimetric feeding and dosing of fine-grained and powdered bulk materials, such as raw meal, limestone, hydrated lime, fly ash or bypass dust. The advanced weighing electronics enable truly consistent feed rates with the utmost reliability. If you combine the rotor weighfeeder with a feed bin, you also have the option of online calibration to ensure reproducible weighing data. As the cement industry increasingly pursues a more environmentally-friendly process, the addition of waste materials such as fly ash or slag to the finish mill will make an important contribution. Accurate dosing will maintain cement strengths while reducing costs and CO2 emissions – and putting your cement plant on the path to MissionZero
FRW Rotor Weighfeeder is typically used in kiln feeding or finish mill feed applications, for cement blending. But what do you need? We will always work with you to determine the best solution for your application.
- Feed rates from 0 – 1000 t/h
- Rotary valve or flow control gate; as pre-feeding device
- Cabinet or field control solutions available
- Improved rotor design with sealings to avoid any blockage of the system and material flushing
- Suitable for installations in low or high ambient temperature environment.
High accuracy. Low maintenance. Reliably consistent.

It is typically used together with a pre-hopper equipped with load cells to enable online calibration. In a standard kiln feed installation, raw meal is transported from the silo into this pre-hopper, where it is weighed. calibrated. From the pre-hopper, the material is fed to the rotor weighfeeder via an electro-pneumatic flow control gate. The speed of the rotor is controlled by the ProsCon® advanced weighing electronics, which controls the speed inverse to the load, ensuring a consistent feed rate. The straightforward design is made even simpler by the fact that it is modular, making for easy installation and maintenance.
