conveyor power calculator. use this calculator to calculate the force, torque and power required from a conveyor to move a load at an angle. if your conveyor is horizontal enter an angle of 0. enter your values for the mass, diameter, beltspeed, friction and angle; select your units as required.
calculated idler load (lbs) = cil = ((11+ (55 x 1.0)) x 4.5) + 0 = 297 lbs where: wb = 11 lbs/ft wm = (1000 x 2000) / (60 x 600 ) = 55 lbs/ft q = 1000 tons per hour vee = 600 fpm si = 4.5 ft kl = 1.0 iml = 0 calculated return idler load (lbs) = cilr = (11 x 10) + 0 = 110 lbs si = 10.0 ft 1 lbf = 4.45 n
required to move the conveyor and the load at a constant speed. the calculation of the total tension is based on a constant speed of the belt including the necessary basic conditions to overcome the frictional resistance and tension forces. in a basic way the effective tension is composed of: • the tension to move with an empty belt, tx; • the tension of move the load horizontally, ty;
the calculation is actually quite simple. if the speed reduction of the chain or belt drive is n:1, then the gearmotor output speed should be n times the speed calculated for the conveyor roller and the torque output should be 1/n times the torque calculated for the conveyor roller.
from your 3000tonnes per hour and a given length of conveyor belt you can work out the power required to shift that amount from :-. (3000/3600)*2m * 9.81 = 16.35kw.
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 x s)/33,000. effective tension. pull needed to move belt and load
2. roller bed belt conveyor - this conveyor increases the amount of load which can be conveyed. this is because the belt is now traveling over rollers which have a very low coefficient of friction. 3. live roller conveyor - live roller conveyors are available in three types: a. belt driven b. chain driven c. spool
the calculation is actually quite simple. if the speed reduction of the chain or belt drive is n:1, then the gearmotor output speed should be n times the speed calculated for the conveyor roller and the torque output should be 1/n times the torque calculated for the conveyor roller.
typical conveyor capacity. 1 in = 25.4 mm. 1 ft3/h = 0.028 m3/h. 1 ft/min = 5.08 x 10-3 m/s. the product cross sectional area is defined by the idler trough shape and the product pile on top of the idler trough the trapezoid shape. this section on top of the trapezoid can be described with a circle and the angle this circle makes with the belt
conveyors, since inclination is a limiting factor. items 1-7 determine the speed and width of the conveyor belt, the power needed for the drive, the type of drive, the number of belt plies, and size of pulleys, shafts and spacing of idlers. items 8-10 determine the quality and thickness of the rubber cover on the belt.
to the live load on the conveyor, add the weight of all the moving components. belting and roller weights are listed in weights and tables add a best estimate of the weight of drive components such as worm gears, chain and sprockets etc. which will vary from system to system.
acceleration: the acceleration of the conveyor belt can be calculated as: a= (tbs – tb)/ [l*(2*mi + 2*mb+mm)]……………………eqn.1.6. where, a is in m/sec2. tbs = the belt tension while starting in n. tb = the belt tension in steady state in n. l = the length of the conveyor in
solids are further classified into two main groups: unit load and bulk material. the successful design of a conveyor belt for bulk material handling begins with an accurate appraisal of the characteristics of the material to be transported. the behavior of bulk materials greatly depends on the moisture content and particle size distribution of the
most importantly, the payload and size of the conveyor will determine the size of the drive and idle rollers. this in turn will influence the size of bearings and other items like timing belts. a subframe for a conveyor carrying a high payload may also require additional strengthening to ensure its integrity. conveyor stand design

e. calculation of the load on idler roll considering troughing idler is used in conveyor system. troughing idler are of two types (1). equal roller, which have all roller of equal size, (2). unequal roller which have middle roller smaller than other roller. the load distribution will
leave the rotor inertia jo and the gear ratio i blank if you have not selected any motor (or geared motor) yet. then, fill in the rest of the form. the software will temporary calculate the acceleration torque with a load/rotor inertia ratio of 5:1. select a product based on the required torque and the required speed.
l = conveyor length in meters. conveyor length is approximately half of the total belt length. g = acceleration due to gravity = 9.81 m/sec 2. mi = load due to the idlers in kg/m. mb = load due to belt in kg/m. mm = load due to the conveyed materials in kg/m. δ = inclination angle of the conveyor

use this calculator to determine the maximum angle for your incline conveyor before a box will tumble. the maximum incline angle is 30 degrees without using a cleated belt. with a cleated belt you may be able to incline up to 45 degrees. this calculator assumes the weight is evenly distributed in the box. contact us if you have a top heavy box.
cerned with vertical curves on the carrying run of the belt conveyor. concave vertical curves a conveyor belt is said to pass through a concave vertical curve when the center of curvature lies above the belt. (see figure 9.1.) in such cases, the gravity forces of the belt and the load (if present) tend to hold the belt down on the idlers while
company, bemdorf. the conveyor is equipped with a hopper for loading product, an almost fully enclosed heat box and a discharge outlet as seen in figure 1. the single belt conveyor is driven by an electric motor in the rear of the conveyor which drives the rear roller through a roller chain and sprocket attachment. this conveyor system is used
determine the overall diameter of the roller plus the thickness of the belt. for example, if the conveyor belt you are using is 1/2-inch thick, the overall diameter is the core diameter, 8 inches, plus twice the thickness of the belt, 1 inch, for a total of 9 inches.
calculation. the design of a roller conveyor begins with calculation of conveyor elements for given initial data: total length, l =20 m, inclination angle, β. =3°, unit c apacity, z =180 unit/h
the additional force from the product is a simple equation based on the material in contact with the rollers. the formulae is simply f=uw where u is the rolling friction and w is the weight of the product in pounds. for u us the following for steel conveyor rollers. metal u = 0.01 to 0.02 plastic u = 0.02 to 0.04 wood u = 0.02 to 0.05
load torque with respect to drive pulley periphery = (aforesaid total resistance) x (drive pulley radius) load torque with respect to motor shaft = (aforesaid torque) divided by { (gear box ratio) x (drive efficiency as a fraction of 1)}. conveyor is composed of
