The calculations prove the correctness of the described methodology The results for the calculated motor power are close to the values of the installed motor power of the apron feeders although they are manufactured by different companies INTRODUCTION Apron feeders AF are widely used in the mining industry for
Apron Feeders are generally used as a primary or bin feeder application designed for varying applications from lightduty to severeduty from low tonnage to high tonnage of material They are the feeder of choice for reliability high uptime and high returns on
We deliver apron feeders that are durable efficient and cost effective When designing apron feeders we take into account many factors such as the type of application the nature of the bulk material the size of the bulk material the capacity of production and
Apron Feeder Calculations bulkonline Forums Nov 23 2006 You would be amazed at how little power it takes to run an apron feeder as they are run through a gear box that is usually reduced down from 3450 rpm or less to x which is the speed of the final driven shaft which powers the sprockets which drive the apron itself The average apron feeder is also capable of running in reverse as well
methods for determining feeder loads and power requirements are presented The interaction between the flow pattern developed and wall pressures generated in mass flow hoppers and the manner in which these influence feeder loads is discussed A simplified methodology is presented for the design of belt feeders and feed hoppers with
The Apron Feeder for mining showcases cast manganese steel aprons SALT chain components and forged alloy steel main shafts The impact loads are absorbed by a natural material bed on top of the feeder and in combination with heavy duty impact beams in the feeding area the Apron Feeder is designed to handle the toughest operational conditions
T 5 wdsc where T tons of ore per hour w effective width of feeder in feet d depth of the layer of ore in inches s speed of feeder in feet per minute c number of cubic feet of broken ore per ton By giving d and s their maximum and minimum values the range of the feed rate can be obtained
Apron feeders are a reliable solution for extracting or feeding ores that are wet sticky dry or even frozen Metso apron feeders diversity can be found throughout the mineral processing circuit fitting different applications with robust designs and high uptime for a more efficient operation
and apron feeders is presented The need for feeders and massflow hoppers to be designed as an integral unit to promote uniform feed is emphasised The acting on feeders in hopperfeeder combinations and the corresponding power requirements Figure 3 illustrates the loads acting in a hopper and feeder
