Belt Conveyors for Bulk Materials - Fifth Edition - Chapter 6

89 Belt Tension Calculations W b =weight of belt in pounds per foot of belt length. When the exact weight of the belt is not known, use average estimated belt weight (see Table 6-1) W m =weight of material, lbs per foot of belt length: Three multiplying factors, K t, K x, and K y, are used in calculations of three of the components of the effective belt tension, T

They do operate at slower speeds than belt feeders, but for a good reason. Normally, the optimal speed of an apron feeder is 0.05-0.40 m/s. If the ores are non-abrasive, the speed can increase to above 0.30 m/s due to the likely reduced wear.

Thermo Scientific Belt Conveyor Scale Handbook

The weight on the conveyor belt is measured by sensing the force on one or more conveyor idlers. The motion of the material is measured by sensing travel of the belt with a device which produces an "output" representing a fixed distance of belt travel. Because the measured force represents weight per unit length (i.e., kg/m or lbs/ft),

The purpose of continuous gravimetric feeding is to uniformly discharge process material at an accurately controlled weight-based rate (e.g., lb/hr or kg/min). This section introduces three operating principles typically employed in plastics processes to accomplish this purpose: Loss-in-Weight, Weigh Belt, and Weigh Meter feeding.

Weigh Belt Overview. Principle. A weigh-belt feeder primarily consists of a short belt-type conveyor that moves the material from inlet to discharge. As material enters the feeder it passes through an inlet shear gate, forming a shallow bed of consistent cross-sectional area. During transport the material bed is weighed, and belt speed is ...

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.

Considerations in Belt Feeder Design & Operation

How Belt Feeders Work. A belt feeder consists of a hopper positioned directly over a belt conveyor. The belt conveyor "pulls" material out from under the hopper, while an adjustable vertical strike-off plate controls the height of material allowed to advance as the belt moves forward, or in other words, the material profile on the belt.
