It was also observed from the experimental results that in order to increase the milling efficiency of a ball mill towards optimum production of material in the desired size class there is a need to correlate the ball size and the feed size distributions.
Jul 05 2020 The balls which could be of different diameter occupy 30 – 50 of the mill volume and its size depends on the feed and mill size. The large balls tend to break down the coarse feed materials and the smaller balls help to form fine product by reducing void spaces between the balls. Ball mills grind material by impact and attrition.
1. Feed and product size distribution of a ball mill are given in the following table Work index Wi of the ore ground is 12 kWh per ton Calculate the energy required for this size reduction if the capacity of the mill is 150 th what would be the power consumption in the mill 20 pnts Mill Product Mill Feed Size fractions um Wt.
Influencing the size of product. Ball mill that works on the principle of impact is an efficient technique of size reduction through grinding. The size reduction is an important factor for many industrial applications as this process is carried out to increase the surface area to intimate mixing and to improve dissolution rate solubility binding strength and dispersion properties.

Rod mills behave differently from ball mills or SAG AG mills. Ball mills need very large balls to begin to break down a hard crushed particle like taconite. They tend to not be very efficient and produce a lot of very fine product especially if the balls arent big enough to smash the largest particles.
Mar 08 2021 It is better to choose a grate discharge ball mill when the required discharge size is in the range of 0.2 to 0.3 mm. Grate discharge ball mill is usually applied in the first grinding system because it can discharge the qualified product immediately. Overflow discharge ball mill
Ball Mill With Product Size Mesh. Feed rate and product particle size particle size measurement from cyclone or other classier overow is the industry practice today the psi 300 particle size analyzer can provide particle size measurements in realtime and with great accuracy as a major supplier of grinding mills
size of rock going into a ball mill. Jaw and gyratory crushers are used for initial size reduction to convert big rocks into small stones this is generally followed by a cone crusher a combination of rod mill and ball mills are then used if the ore must be ground below mesh m instead of grinding the ore dry slurry is used as feed for rod or ball mills to avoid dusting

Ball mill factors influencing the size of productTherefore it is important to maintain the size of products there are many factors that influence the size of product some of these factors are Feed rate – With a high feed rate less size reduction is effected since in this case the material is present in the mill for a shorter time.As a leading global manufacturer of crushing equipment .
If a ball mill uses little or no water during grinding it is a dry mill. If a ball mill uses water during grinding it is a wet mill. A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills.
Ball Mill Working Principle. To be chosen according to the grinding material material is composed of a ball mill feed end of the hollow shaft is arranged in the tube body when the ball mill cylinder rotation time grinding body due to inertia and centrifugal force the effects of friction making it attached to the cylinder liner on the cylinder body away when taken to the height of a .

The ball mill accepts the SAG or AG mill product. Ball mills give a controlled final grind and produce flotation feed of a uniform size. Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds.
Ball Size Distribution In practice at mill startup instead of charging a single size of ball usually a range of ball sizes is initially added.7.6 A ball mill is to produce a grind of 34 micron Pso product from a feed size of 200 microns at a rate of 1.5 th.
