belt feeder calcualtion with multiple hoppers in uganda

Figure 1 HopperFeeder combinations for loading conveyor belts ii Feeder The feeder controls and meters the flow of bulk material from the hopper to meet the specified discharge flow rate The importance of the hopper and feeder to be designed as an integral unit cannot be too greatly emphasised A well designed hopper may be prevented

The belt feeder discharge is positive volumetric in nature The typical capacity range is up to 1500 m3hour 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 132 Apron feeders

Some belt feeders are wellsuited to hoppers while others are better for augers Again the feeder style depends on the required accuracy level the operations and the kind of products in auger conveyors as an example these systems are responsible for churning liquids slurry or solid materials

vibrating conveyors SEP004 is an instrument that uses vibration to “feed” material to a process or are mainly used to transport a large number of smaller objects to the belt conveyor bucket elevator multihead weigher etc Standard Hopper volume 800mm X

STEP 2 Calculate the hopper angle for mass flow It is usually desirable to have a mass flow happening in silos or hoppers Jenicke has tabulated for different wall friction angle and internal friction angle the maximum hopper angle for which we can get a mass flow 14 Feeders used at discharge of hopper Feeders are positioned after a

A feeder must be designed so that it is an integral part of the hopper the feeder supplements the forces of gravity as in silo design and does not impose additional consolidation pressures into the product – this is of utmost importance when handling cohesive high

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 eg cu fthr The four most common types of such feeders are screw belt rotary valve and vibrating pan A gravimetric feeder on the

hopper shown in Figure4 has an elongated material outlet the outlet width can be half that of a coneshaped hopper without causing material bridging When using a planeflow hopper however you must ensure that the feeder below the hopper is designed to effectively work with the elongated hopper outlet discussed below Expandedflow hopper

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 61 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
