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. 1.3.2 Apron feeders

The conveyor following the belt feeder commonly employs a belt scale. A belt scale weighs the material on the conveyor in order to confirm the desired feed rate. Belt scales are particularly useful when material is prone to flow problems such as ratholing as it can help to indicate when a reduction in feed rate has occurred.

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 load feeder belts often run at high ten-sion making it difficult to trough a belt. In addition the high head load of belt feed-ers makes sealing difficult. This difficulty

Mar 07 2007 Free-of-charge Bulk Conveyor Calculation Program For many years Jansen amp Heuning is providing a calculation program for belt conveyors bucket elevators screw conveyors and chain conveyors. The program is very easy to use in the English language and has extended help files to explain how the calculations are done and based on what formulas or data.

May 03 2009 Hi everybody I am designing a belt feeder to convey coal at 450 TPH having 35 deg troughing1200mm wide belt and BD of 850 Kgcu.m. while I was calculating the capacity for optimum selection I found that the feeder has to run at 1 ms. but I am in doubt for the maximum speed for belt feeders. Many of readymade belt feeder manufacturers suggests a maximum speed of 0.6ms.

Conveyor belts are most commonly used to transport bulk material. Allegheny Manufacturing designs and manufactures heavy- duty conveyor systems for many different applications from fine powders to large lump materials. We provide a total capability relative to the design manufacture and installation of custom engineered belt conveyors and .

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

Notes As a rule of thumb the maximum angle for conveying cardboard boxes is 25 degrees. If conveying plastic containers 15 degrees is typically the maximum incline. The conveyor can be inclined up to 30 degrees. Use our Box Tumbling Calculator to find the maximum incline angle for your containers. You may also be interested Incline Conveyors.
