Gravel is being dumped from a conveyor belt at a rate of 50 cubic feet per minute It forms a pile in the shape of a right circular cone whose base diameter and height are always equal How fast is the height of the pile increasing when the pile is 22 feet high
Belt Conveyors for Bulk Materials Calculations by CEMA ·Determine the density of the material in pounds per cubic foot lb/ft3 3 Choose the idler shape 4 Select a suitable conveyor belt speed 5 Convert the desired tonnage per hour tph to be conveyed to the equivalent in cubic feet per hour ft3/hr ex 1000 tph x 2000 / 60 = 33333 ft3/hr 6 Convert the desired capacity in cubic feet per
Belt Speed Expressed in feet per minute FPM S=D x RPM x 2618 x Belt Load At one time when the load is known per square foot P= G 1 x C in feet x W in feet At one time when load is known by pounds per hour P=G 2 / S x 60 x C in feet Horsepower Level Conveyors HP= F x S x P M /33 000 Inclined Conveyors HP= P x B P M x F
4 ·Feet Per Minute FPM is a standard measure of conveyor speed It measures the number of feet the belt moves in one minute Conveyor speeds are typically in the 5 200 FPM range Skip to content Search Search Contact Us 513 753 6000 Configurator; Conveyors Product Overview
relatively short conveyor less than 100 feet long a belt speed of 600 FPM would result in a low frequency factor meaning the conveyor requires a belting with a very heavy and costly belt top cover thickness But if the conveyor is 1 200 feet long the frequency factor increases allowing min imal top cover thickness In many long conveyor

Stop throwing thousands of dollars at renting gravel conveyors each month and get your own equipment that meets all of your conveyor system needs Dirt sand cement aggregate you name it our gravel conveyors are built to last and increase your profit on every job Moves up to 100 Cubic Yards per hour 70 foot slinging distance
This calculator will allow users to input the parameters for the conveyor belt and display the calculated speed based on the formula $$ text{Speed FPM } = frac{text{Length of the Belt} times text{RPM} times pi}{60} $$ Where Speed is in feet per minute FPM Length of the belt is the distance covered in one complete revolution in feet
