Milling Horsepower Calculator. Calculate the horsepower required for a milling operation based on the feed rate and depth of cut, which are used to determine the material removal rate (or metal removal rate). Also required is the unit power, which is a material property describing the amount of power required to cut that material.
If you know the maximum torque rating of your spindle motor, T max, it is easy to calculate the max cutting force using the formula below, where T max is in inchlbs, and r tool is in inches. If the maximum cutting force calculated from the spindle torque rating is higher than from the maximum power rating, then we will use that value.

Batches per hour is design capacity per hour divided by tons per batch = tph/3 tons per batch = batches per hour. Cycle time = 60 minutes per hour/ batches per hour = minutes per batch. Converting to seconds per cycle = x 60 = 288 seconds per mixer cycle.
1 Answer. Sorted by: 1. Torque, τ τ, is required for rotational acceleration, τ = Iα τ = I α, and for viscous losses, τ = bω τ = b ω. Here I'm using ϕ ϕ for angular position, ω ω for angular velocity, and α α for angular acceleration. I I is the moment of inertia as "seen" by whatever you care about, and b b is damping constant ...

If a mill rolls 80 % of the calendar year, that is 365 x 24 x = 7008 hours. If the mill rolls 800,000 tons per year, it runs at an average production rate of tons/hour. If the utilization can be improved by 1 %, the available rolling hours is 365 x 24 x =, creating extra rolling hours.
At least 60+ inLb torque at whatever your speed, but 175 RPM is a sweet spot. Mine is a 1725 RPM 1/3 HP that gives me 100 inLb torque at 172 RPM with aid of a 10:1 ratio gearbox (reducer). This is an easy motor to find on ebay. So, I'd not go any less than 1/4 HP, to directly answer your question. OP. A.
The torque at the huller is equal to 1 ft x lb = ftlb. The torque at the grinder is equal to 1 ft x lbs = ftlb. The total torque can be measured by adding all the torque from the prototype and is equal to + = ft lb . Figure 3. Free Body Diagram of the measurement of Torque

Using a ⅛" (.125") diameter cutter instead of a ¼" (.25") cutter the required RPM for aluminum example will be:. 500SFM X / .125 = 15,280rpm. This would be in the range of a typical cnc router. The next issue would be the feedrate. Using an RPM of 15,280 would give a feedrate of 122 in/min.
If feed is valued at 300 per ton and the shrink (loss) is %, the cost of the shrink would be 300 x .0081 = per ton. If the feed mill produces 6,000 tons per week, the shrink loss value at per ton would be 14,500. That is significant, and that is why shrink must be measured and managed to keep it at a minimum.
The proper sizing of threephase induction motors saves energy and reduces downtime.
To calculate load torque, multiply the force (F) by the distance away from the rotational axis, which is the radius of the pulley (r) . If the mass of the load (blue box) is 20 Newtons, and the radius of the pulley is 5 cm away, then the required torque for the application is 20 N x m = 1 Nm. Typically, a safety factor is used so that the ...
Roller mills accomplish size reduction through a combination of forces and design features. If the rolls rotate at the same speed, compression is the primary force used. If the rolls rotate at different speeds, shearing Hammermills and Roller Mills Kim Koch Northern Crops Institute North Dakota State University Fargo, ND
The bulk deformation flattens the (mostly equiaxed and recrystallised) grains (Fig. ), further aligns the constituent and dispersed particles (Fig. ), and generates the typical FCC rolling texture (Fig. ).Cold rolling significantly strain hardens the material, as it generates a high dislocation density present in a stable and fine subgrain structure (about μm subgrain ...
tor to the spindles, thus obtaining higher torque. The correlations between rotational speed and power and torque, respectively, using different gears are shown in Figs. 6 and 7. Note how each correlation gives symmetrical curves for all gears. Peripheral speed Peripheral speed is determined by wheel diameter and rotational speed.
Here's what I got: 3450 RPM 5 HP motor with a 2" pulley Mandrel with a 4" to 2" step Pulley Mandrel with an 8" pulley and a coupling to drive the grain mill. First belt 2" drive (at 3450 rpm) to 4" driven resulting in 1725 RPM Second Belt 2" drive (at 1725 rpm) to 8" driven resulting in RPM operating speed of the mill.
We will need to know the number of inches pre revolution. This is pretty easy since it's the screw # of threads per inch. You will also need to know the pi. Pi is half of a circle in radians, or rounded to the ten millionth. The formula is as follows: Torque = ( (weight) (inches/revolution))/2 (pi) (efficiency).
