Power Calculations V-Belt . Power is a measure of performance or capacity and is defined as the amount of work performed in a given time. The most work accomplished in the least amount of time, equals greater power. This formula also shows the relation between torque and HP. Power in hp (HP) can be calculated using the following formulas:

Feb 07, 2013· HP = Total horsepower * All assumptions and calculations in this study are assumed using a full auger. Figure 1 shows the overall capacity of all three feeder sizes with various size augers. The 8-, 10-, and 12-in. are not part of the standard auger for these types of feeders, but are shown for completeness of data.
Belt Widths The belt widths are as follows: 18, 24, 30, 36, 42, 48, 54, 60, 72, 84, and 96 inches. The width of the narrower belts may be governed by the size of lumps to be handled. Belts must be wide enough so that any combination of prevailing lumps and finer material does not load the lumps too close to the edge of the conveyor belt.

Amps = HP × 746 V × η × PF. Thus, the current in amps is equal to horsepower times 746 divided by the voltage times the efficiency η times the power factor. For example, let’s find the current draw in amps of a 1 horsepower motor that runs at 120 volts with a 90% efficiency. Amps = 1 HP × 746 W 120 V × .9. Amps = 746 120 V × .9.
Since one horsepower (HP) = 33,000 ft-lbs/min, required conveyor drive power may be expressed in HP as follows, (Te in lbs) x (V in fpm)/ ((33,000 ft-lbs/min)/HP) = HP After calculating Te, it is important to calculate T2 slip (slack side tension required to resist slippage of the belt …
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 …

May 16, 2014· Belt Speed (BS): The calculator computes the belt speed (BS) in meters per second. However, this can be automatically converted to other velocity units via the pull-down menu. The Math. The formula for the speed of the belt is: BS = (D •π • R)/(2π) = ½•D•RPM. where: BS is the Belt Speed; D is the diameter of the pulley
May 31, 2016· Feeders are driven by less than one horsepower up to 40-hp motors, depending on feeder size and expected load. The main point to consider in selecting a feeder is that it must provide an even flow of material to the primary crusher. The size of the feeder and its speed should provide a capacity 25-35% greater than the capacity of the crusher.
Power in hp (HP) can be calculated using the following formulas: HP = [T x RPM] / 63025, When T is given in lb-in or HP = [T x RPM] / / 5252, When T is given in lb-ft Hp to Kilowatts, HP = Kw x 1.341

The minimum number of teeth are found in the horsepower tables on pages 6-19. To determine, first calculate the Horsepower Table Rating (HP Table) from the following
In summary, the active weight of material on the feeder belt and, therefore, hopper drag load are linearly proportional to the active volume. Our example demonstrated that reducing active volume from 154 ft 3 to 77 ft 3, reduces drag load from 6,769 lbs to 3,384 lbs. This, in turn, reduced required conveyor drive power from 23.2 HP to 12.2 HP.
Oct 19, 2018· The belt speed calculation always involves certain element of subjectivity, because most suitable speed will depend upon the exact nature of material and belt feeder …
The belt feeder discharge is positive volumetric in nature. The typical capacity range is up to 1500 m3/hour, for regularly used belt widths. However, belt feeders of higher capacities are also possible. As an example, a mine in Germany has 6400 mm wide belt feeder for handling lignite at much higher capacity. 1.3.2 Apron feeders
BELT CONVEYORS & BELT DRIVEN LIVE ROLLERS + Product (Total Live Load)* + Belt Weight** + Roller Weight (N/A on Slider Bed Belt Conv.)** + Drive Weight (250#) = Subtotal x Friction Factor (See Chart This Page) x 1.25 (25% Contingency Factor) = Effective Belt Pull x Speed of Conveyor ÷ .95 Chain Reductions ÷ .85 GRE / Reducer Losses = Horsepower
The original design for this feeder was to deliver 18 tonnes per hour with a belt speed of 0.026 meters per second. The original design for kimberlite feeder was for a hopper slot length of 20 meters.

A belt feeder consists of a hopper positioned directly over a belt conveyor. The belt conveyor “pulls” material out from under the hopper, while an adjustable vertical strike-off plate controls the height of material allowed to advance as the belt moves forward, or in other words, the material profile on the belt.
Jan 11, 2008· One with a calculator can reconstruct these figures working from HP transmitted to driving pulley diameter and RPM. That said: The Gates Heavy Duty V Belt Drive Design manual shows that a "A" V-belt section will transmit about 2.2 HP per belt for a minimum pulley OD of 3" at 1750 RPM. Derate non-linearly for smaller diameter.
In summary, the active weight of material on the feeder belt and, therefore, hopper drag load are linearly proportional to the active volume. Our example demonstrated that reducing active volume from 154 ft 3 to 77 ft 3, reduces drag load from 6,769 lbs to 3,384 lbs. This, in turn, reduced required conveyor drive power from 23.2 HP to 12.2 HP.
