Efficient and accurate weighing, feeding and dosing
Market leader with rotor weighfeeders
FLSmidth Pfister® has established its name through a vast number of technical innovations for many applications and lines of business. Pfister® is an international leader in rotor weighfeeder technology for precise dosing of various materials.
One of the many advantages of this technology: The systems can be applied multifariously – in different lines of business and for various purposes. In cement manufacturing e.g., Pfister® technologies are useful in all stages of production: from the raw mill, the kiln plant to the finish mill and cement preloading.
Our diverse and unique product portfolio
The Pfister® product range consists of classical linear dosing systems consisting of belt weighfeeders as well as the famous rotor weighfeeders and measuring scales. The performance range of these technologically advanced systems spans from dosing of fine products such as cement, coal dust, alternative fuels, raw meal or fly ashes to dosing of coarse materials such as clinker, raw coal or additives.
Especially in the field of dosing alternative fuels such as fluff, plastic, RDF, animal meal, tetra pack, biomasses etc., the rotor weighfeeder finds a broad field of employment as a multi-fuel system. Whether the materials to be dosed are pulverised, flaky or fibrous: Pfister® dosing systems are adjusted individually to the needs of the customer and each individual application.
Behind all Pfister® products and solutions stand state-of-the-art, user-friendly Pfister® control electronics.
Many feeders from other manufacturers are based on a reactive control (follow-up), but Pfister® feeders utilise pro-active control.
In the pro-active rotor weighfeeder, the material mass is measured before it leaves the rotor weighfeeder. That means that the speed of the rotor is adjusted before the material is discharged into the system. The result is extremely high short and long-term accuracy.
