Volumetric Feeder Gravimetric Feeder (Source: internal survey) Gravimetric feeding with Pfister® rotor weighfeeders has substantial advantages over volumetric feeding. These advantages are essential for constant, reliable fuel feeding to the kilns or boilers and a big step towards more economical and ecological operation of plants.
Gravimetric Feeders. Gravimetric feeders proportion chemicals by weight rather than by volume, and are accurate to within 1-2%. A gravimetric feeder is a scale, balanced to ensure delivery of a desired weight of chemical to the system. The chemical discharged by a gravimetric feeder is usually put into solution or suspension.
Gravimetric feeders compensate for variations in bulk density due to moisture, coal size, and other factors. They provide a precise weight of coal to the downstream components. In the most common gravimetric feeder system, coal is carried over a load cell that monitors the coal weight on a belt.

The gravimetric feeder compensates for the variation in bulk density and feeds a fixed weight of coal in response to a boiler fuel demand Siya Metals Private Limited Fazal Ganj, Kanpur No. 123/751, Block T-74, Pratap Ganj Gadarian Purwa, Fazal Ganj, Fazal Ganj, Kanpur - 208019, Uttar Pradesh
Generally, the gravimetric feeder receives the particulate coal in the form of a continuous stream in a fixed flow path, and delivers the coal at a controlled rate as free-falling or separately flowing particles. The rate of discharge by weight is controllable to achieve accurate control of the fuel-air ratio.
