# how to calculate load inertia for a ball mill

Sep 29, 2016 · Inertia of load driven by belt (or rack and pinion) m = mass of load + mass of belt (or pinion) Also, the radius in this case is the outer radius of the pulley, since this is the axis around which the belt and load are being rotated

We believes the value of brand, which originates from not only excellent products and solutions, but also considerate pre-sales & after-sales technical services. After the sales, we will also have a 24-hour online after-sales service team to serve you. please be relief, Our service will make you satisfied.

• Calculating a grinding circuit’s circulating loads based on Screen Analysis of its slurries. Compared to %Solids or Density based Circulating load equations, a more precise method of determining grinding circuit tonnages uses the screen size distributions of the pulps instead of the dilution ratios. Pulp samples collected around the ball mill or rod mill …

In leadscrew with one start, pitch = lead. With multiple starts pitch = lead / # starts. In many leadscrew catalogues, the equation listed for translating a load's linear mass into angular inertia is: J l o a d = m × ( 1 2 π p) 2. where: m is the mass of the load. p is the pitch in threads per inch

• ### etap motor starting study for 600kw ball mill- electric

From what I've seen of ball mills, the chamber would have a certain amount of inertia, but at a very low speed. The balls and the charge in the mill would seem to work against the inherent inertia. Seems like a pretty high torque load with somebody's foot on the brake pedal all the time

• ### ball mill design/power calculation

The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or …

• ### the fundamentals of ball screws| machine design

Calculate the equivalent axial load, F m, using: where F i = each increment of axial load (N); q i = percent of stroke at load F i ; and n i = rotational speed at load F i (rpm)

• ### motor sizing calculations

Theoretically, inertia is factor of mass so it should not include gravity, however, practically we can not easily measure mass on the earth. Oriental Motor commonly provides inertia in oz-in². Then, when we calculate the Acceleration Torque in Torque Calculation we divide the total the total inertia by the gravity from. Gravity = 386 in/sec²
