Product size is estimated as a func tion of size and hardness of the mill feed and milling operating conditions napiermunn et al 1996 a more reali stic approach is the socalled population
Effect of liner type on the ball mill product size ball mill 1 700kw with current working amper 1000 a average product size d80 45 micron critical speed 7580 ore work index 12kwht solid percent 7080 ball mill charge 40 and 60 mm no hydrocyclone with first ball mill ie open circuit
Ball size as initial charge commercial ball sizes 10 150 mm number size and mass of each ball size depends on mill load and whether or not the media is being added as the initial charge for the initial chargin of a mill coghill and devaney 1937 defined the ball size as a function of the top size of the feed ie dv 040 kf
Sep 01 2013 it is possible then to incorporate this information into a grinding model and investigate the effect of the makeup ball size on the mill performance with various feed and product specifications concha et al 3 was the first to combine a grinding circuit model with a ball wear model to optimize the makeup ball charge
13082014 1 class exercise product size distribution a hard ore is ground in a ball mill and the product size distribution is shown as grind a in the table the downstream process was giving problems and was found to be sensitive to large particles in order to eliminate these problems the mill is modified with the aim of producing a grind with a smaller average particle size
The starting point for ball mill media and solids charging generally starts as follows 50 media charge assuming 26 void space between spherical balls nonspherical irregularly shaped and mixedsize media will increase or decrease the free space 50 x 26 13 free space add to this another 1015 above the ball charge for total of 23 to 25 product loading so as a rule of thumb we use 25

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
Retsch is the world leading manufacturer of laboratory ball mills and offers the perfect product for each application the high energy ball mill e max and mm 500 were developed for grinding with the highest energy input the innovative design of both the mills and the grinding jars allows for continuous grinding down to the nano range in the shortest amount of time with only minor warming
Ball mill is the key equipment for deep grinding of materials after primary crushing it is widely used in cement silicate products new building materials wearresistant materials fertilizers ferrous and nonferrous metal mineral processing and glass ceramics industries
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 pulp density feed size as f80 and maximum chunk size product size as p80 and maximum and finally the type of circuit openclosed
In coarse grinding when the product size is 13mm the processing capacity of the rod mill is greater than that of the ball millusually the feed size of rod mill is 1523mm in fine grinding when the product size is 05mm the grinding effect of the ball mill is greater than that of the rod millthe feeding particle size of ball mill is generally 525 mm
It is better to choose a grate discharge ball mill when the required discharge size is in the range of 02 to 03 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
Low price small size ball mill mini ball mill with 501000 kgh capacity ball mill this machine works in both dry and wet methods intermittently to mill mix and discharge materials such as feldspar quartz and clay the slurry can pass through 1000 sieve pore
Ball mill is a type of grinder used to grind materials into extremely fine powder for use in mineral dressing processes it works on the principle of impact size reduction is done by impact as the balls drop from near the top of the shell
Furthermore you are able to minimize the feed ball size to achieve higher degree of efficiency of ball grinding which is exceedingly useful for a large amount of grinding this type of rod mills normally feeds balls of less than 15 to 30 mm in diameter to produce 80 product size 500 to 1000m
In ball milling of dry solids the main independent variables are mill diameter mill speed media size solids loading and residence time for most companies the production mill already exists so we can ignore mill diameter and focus on the other variables
First a jar mill grindability test requires a 5 lb 2 kg sample and produces a direct measured specific energy net hphrt to grind from the design feed size to the required product size the second test a bond work index determination results in a specific energy value net hphrt from an empirical formula
Ball mill classifier systems have been improved over time and are now capable of achieving much finer products in the past a particle size with a d97 of 10 microns was only possible now particle sizes down to a d97 of less than 35 microns can be achieved with a d50 in the range of 15 microns
The rods grind the ore by tumbling within the the mill similar to the grinding balls in a ball mill to prevent the conditions leading to rod charge tangling the length to diameter ratio is maintained at 14 to 16 rod mills accept feed up to about 50 mm 2 in and produce a product in the size range of 3000 to 270 mm 4 to 35 mesh
