Motor sizing results. variable speed belt conveyor. the motor sizing results are as follows well need to findotor that meets these primary requirements. we will skip required stopping accuracy and other requirementor this example. load inertia 58,752 ozinequired speed 19.138.2 rpm.
Calculating the optimum motor size depends on considering all the variables and following the right equations. 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 whenox hits the stop, plus the efficiency of the.
The first step in sizingcrew conveyor is to determine the diameter. the diameter isunction of the rate of the conveyed material, its density, trough fill level, screw pitch and speed of the screw. to ease the calculation, most screw conveyors are full pitch, meaning the distance from flight to flight is the same as the diameter, and are.

The design of the screw is based on the theory of the inclined plane. the screw conveyor began to evolve in the late 1800s and was used aseans of increasing food and grain production to meet the needs of the rapidly growing american population. the first feed mills used screw conveyors throughout the process.
All conveyors require an additional belt tension in order to allow the pulley to drive forward an effective tension without slipping. inase ofimple horizontal conveyor t1 is the sum of the effective tension te and the slack side, the tension t2. for the inclined conveyor, additional tensions are induced due.

Example model ta, 11 ft long requires 12 hp motor at 65 feet per minute forotal load of 320 pounds. you desire your conveyor to operate at 90 feet per minute. calculate as follows 120 65 .69. you should select the next highest horsepower or 34 hp. this formula may be used to give youood estimate, but we.
Inutshell if your trying to sizeotor you start at the conveyor and work backward accounting for the different loads, gearboxes, couplings etc then you have too allow for efficiencies and friction as well as deciding how quickly you want the system up to full speed, this last requirement alone will haveassive affect on motor size.
