Advanced Uses for Weigh Belt Feeder Data ...
· Advanced Uses for Weigh Belt Feeder Data. A weigh belt feeder is a device that can control the rate at which a bulk material is metered into a downstream process by weight rather than by volume. A weigh belt feeder normally is equipped with a weight-sensing device such as a load cell, as well as a belt travel device such as an encoder.
How to Calculate Hopper Drag Load, Power, & Pressure ...
In summary, the active weight of material on the feeder belt and, therefore, hopper drag load are linearly proportional to the active volume. Our example demonstrated that reducing active volume from 154 ft 3 to 77 ft 3, reduces drag load from 6,769 lbs to 3,384 lbs.

How to Design Efficient and Reliable Feeders for Bulk Solids
There are two basic types of feeders used in industrial plants: volumetric and gravimetric. As its name implies, a volumetric feeder modulates and controls the volumetric rate of discharge from a bin (e.g., cu. ft./hr.). The four most common types of such feeders are screw, belt, rotary valve, and vibrating pan. A gravimetric feeder, on the ...

Apron Feeder Calculations
· 10) If the apron feeder has inclination add for the lift resistance. 11) Calculate the material shear resistance below hopper outlet. 12) Consider about 4% extra resistance for terminal sprocket etc. 13) In case the apron pans are partially sliding below feed zone then add the resistnace for the same. 14) Add up all resistance.
Gravimetric and Volumetric Coal Feed Systems for Boilers
The STOCK® gravimetric feeder weighs material on a belt between two fixed points (span) precisely located in the feeder body. A roller, located midway in the span and supported at each end by precision load cells, supports half the weight on the span. The load cells generate an electrical signal directly proportional to the weight supported.

SECTION 2 loading the belt
Belt feeders use flat belts almost exclu-sively. This is because feeders are gener-ally very short, and they must fit into operations where there is little room to form the belt into a trough. Feeders typi-cally operate with very high loads and use heavy-duty idlers. Many feeder belts can reverse direction. To move a large material

Belt Widths The belt widths are as follows: 18, 24, 30, 36, 42, 48, 54, 60, 72, 84, and 96 inches. The width of the narrower belts may be governed by the size of lumps to be handled. Belts must be wide enough so that any combination of prevailing lumps and finer material does not load the lumps too close to the edge of the conveyor belt.

The belt feeder discharge is positive volumetric in nature. The typical capacity range is up to 1500 m3/hour, for regularly used belt widths. However, belt feeders of higher capacities are also possible. As an example, a mine in Germany has 6400 mm wide belt feeder for handling lignite at much higher capacity. 1.3.2 Apron feeders
What is a Weigh Feeder ?
Weigh Feeder. The load cell measures the weight of a fixed-length belt section, yielding a figure of material weight per linear distance on the belt. A tachometer (speed sensor) measures the speed of the belt. The product of these two variables is the mass flow rate of solid material "through" the weigh feeder: A small weigh feeder (about ...
