Face Width – The length of a pulley's cylindrical body.This area is intended to act as the contact surface for the conveyor belt.
You desire your conveyor to operate at 90 Feet Per Minute. Calculate as follows: (1/2 X 90) / 65 = .69. You should select the next highest horsepower or 3/4 Hp. This formula should provide you with a good estimate, but it's always best to confirm it with conveyor experts. Ask us to do a complete horsepower calculation if this causes any concerns.
Dec 08, 2016· Benefits of VFD's on Bulk Material Handling Conveyors. When installed on bulk material handling conveyors, VFD's provide the following benefits: Equipment start-up control. When started "across the line", an AC motor can draw a significant amount of current, often as much as eight times the normal full load current normally drawn by the ...
conveyors and those handling all other materials. • Maximum incline using standard equipment is 5°. Conveyors can be inclined to a maximum of 10° using close spaced flights. • Riley Equipment is not responsible for the capacity of conveyors on an incline, unless approved by our engineering department.

STANDARD PRODUCT CATALOGUE: engineered material handling systems: return to main page: Technical Page 2 HORSEPOWER CALCULATIONS The Basic Principles "Horsepower" is a measure devised by 19th century manufacturers of steam engines (literally "engineers") to compare the work performed by their machines with the amount more traditionally achieved using horses and pit ponies.
Jun 12, 2012· For example, simply calculating the total resistance that the motor has to overcome involves the weight and friction of the conveyor itself carrying the load, additional friction when a box hits the stop, plus the efficiency of the gear unit itself attached to the motor. Here is the calculation for determining the resistance force of the ...
Jul 21, 2017· 7 foot conveyor discharge height x 5000 bushels per hour = 35,000 divided by 26,500 = 1.3208 5000 bushels per hour divided by 1325 (curve section factor) = 3.7736 Add 4.5455 + 1.3208 + 3.7736 = 9.6399 total required horsepower (Round up to the nearest motor means this conveyor requires a 10 HP electric motor.)
