Feeding >15mm to a ball mill this size is not typical much larger ball mills (>21'' or diameter) typically get 1216mm feed (from what I have seen in my experience) With regards to " 4" media, typically for Ball mills of this size (16''), max size of ball used should be around the 5060mm.
1. Introduction. The ball size is one of the critical factors for determining the mill performance of ball mills. It is well known that larger balls are needed for the effective breakage of largesize particles, whereas smaller balls are more effective for the breakage of fine particles.

Dec 03, 2010· Re: Ball Mill Load feed. Dear GKS, You are correct in stating that main drive kw only increase when less grinding media charge and small size of grinding media feed size and feed rate. However, it was to be stated in my reply that Kwh/t of material increases in chocked condition of the mill as there is no output from the mill. Warm regards
W is the work index measured in a laboratory ball mill (kilowatthours per metric or short ton) P 80 is the mill circuit product size in micrometers; F 80 is the mill circuit feed size in micrometers. Rod mill. A rotating drum causes friction and attrition between steel rods and ore particles. [citation needed] But note that the term ''rod mill ...
A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotati
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.
Jun 15, 2018· Then, Maximum ball size for ball mill grinding is B(mm) Example: Size of the mill feed (80% passing in microns'' size) = 15000 microns (15mm) Work index for the feed = 18 kwh/ %age of mill in critical speed = 70%. Specific gravity of the feed = gm/cm3. Mill effective diameter = m.

For ball mill, Bond (1958) was proposing an empirical formula giving the top size of balls (makeup balls) DM function of the feed size xG (80% passing size µm), the ore true specific gravity sg, the ore Bond Work Index Wi (kWh/st), the fraction of critical speed fc and the inside mill diameter D (m):
feed size of iron ore to ball mill Ball Mills an overview ScienceDirect Topics. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually times the shell diameter (Figure ).The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing ...
minetomill optimisation effect of feed size on mill throughput no8 srk consultings international newsletter one of the most valuable aspects of blasting is the generation of very fine particles e, smaller than 12mm that will pass through the primary mills and onto the secondary ball mill circuits, alleviating a common bottleneck.
Minetomill optimisation: effect of feed size on mill... SRK Consulting mills and onto the secondary ball mill circuits, alleviating a common bottleneck. Modifying blasting practices to achieve a more suitable mill feed size – which ...
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. The feed to ball mills (dry basis) is typically 75 vol.% ore and 25% steel. The ball mill is operated in closed circuit with a particlesize measurement device and sizecontrol cyclones.
How can one select ball size in ball milling and how much material should be taken in mill pot? ... If the powder is feed for milling then smaller ball size is preferred for homogeneous mixing and ...
Closed Circuit Ball Mill System. Clinker, Gypsum and other desired additives are fed to the ball mill in specific proportions based on the quality requirement. Feed material is ground in the ball mill, discharged and fed to a classifier with the help of a bucket elevator for classification of the ground cement into two streams – coarse and fines.
For efficient operation of ball mills necessary to observe the right balance between balls size and feed material size. If the feed material contains many large lumps and grinding balls can''t crush them, it leads to a gradual accumulation them between the balls. As a result, mill suspends own operation.
How ball mills work. A ball mill grinds material by rotating a cylinder filled with media (typically metallic or ceramic balls) mixed with a continuous flow of feed and recycled material. At slower rotational speeds, the grinding media creates a cascade motion where the media is mainly rolling and shear forces for grinding are generated.
Jun 20, 2019· Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill .
Jun 25, 2018· Specific gravity of the feed = gm/cm3. Mill effective diameter = m . 335 is a constant used for dry grinding with steel balls in the mill. Actual size of media is taken is lower than the calculated value. It is around 80 to 90 mm. If you Wants to reduce the maximum ball size, thenreduce the feed size by using pregrinding operation.
