Hopper SOME EXTRACTS FROM THE BOOK BELT FEEDER

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

2.Feeder Loads Design EquationsConsider the mass-flow hopper and feeder of Fig 13 It needs to be noted that the depth of the hopper Zg should be such that Zg/D > 0 67 in order to ensure that the surcharge pressure Pg can be adequately supported by the upper section of the hopper walls The design equations used to determine the feeder loads are

CONCEPTS OF FEEDER DESIGN AND PERFORMANCE IN

The basic design features of belt and apron feeders is presented. The need for feeders and mass-flow hoppers to be designed as an integral unit to promote uniform feed is emphasised. The essential requirement is to promote uniform feed with the whole of the hopper/feeder interface active. The methods for determining feeder loads and

done either on a continuous basis (the feeder modulates the mass per unit time of material discharge) or on a batch basis (a certain mass of material is discharged and then the feeder shuts off). The two most common types of gravimetric feeders are loss-in-weight and weigh belt. Gravimetric feeders should be used whenever

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.

Conveyor belt Wikipedia

A conveyor belt is the carrying medium of a belt conveyor system (often shortened to belt conveyor). A belt conveyor system is one of many types of conveyor systems.A belt conveyor system consists of two or more pulleys (sometimes referred to as drums), with a closed loop of carrying medium—the conveyor belt—that rotates about them. One or both of the pulleys are powered, moving the belt
