Very large tonnages can be ground with these ball mills because they are very effective material handling devices. Ball mills are rated by power rather than capacity. Today, the largest ball mill in operation is 8.53 m diameter and 13.41 m long with a corresponding motor power of 22 MW (Toromocho, private communications).
15-10-2015· B) Overflow Discharge Mills operating at low ball fillings slurry may accumulate on top of the ball charge; causing, the Total Charge Filling Level to be higher than the Ball Filling Level. Grate Discharge mills will not face this issue. C) This value represents the Volumetric Fractional Filling of the Voids in between the balls by the retained slurry in the mill charge. As defined, this value should never exceed 100%, but in some cases particularly in Grate Discharge Mills

Ball Mills. Ball mills have been used for the preparation of coal–oil and conventional coal–water slurry fuels, also in large sizes up to a capacity of 50 tonnes of coal per hour (Austin et al., 1984).
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 particle-size measurement device and size-control cyclones.
For overflow ball mills, the charge should not exceed 45% of the mill volume . For grate discharge mills, the charge should occupy about 50% of the mill volume . Bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge, He, and the radius of the mill, R, i.e.,
27-01-2021· Charging capacity of grinding medium: 230 ton. The raw material for cement production has a high abrasion rate. Consequently, when calculating the assortment the balls with increased volumetric hardness have been taken into account. Into the first chamber of two-chamber mill is loaded with balls from 80 to 40 mm in diameter.

A Ball mill is a horizontal cylinder partly filled with steel balls (or occasionally other shapes) that rotates on its axis, imparting a tumbling and cascading action to the balls. Material fed through the mill is crushed by impact and ground by attrition between the balls. The grinding media are usually made of high-chromium steel.The smaller grades are occasionally cylindrical ("pebs

Ball mill machine is mainly composed of feeding part, discharging part, rotary part and driving part which includes reducer, small drive gear, electrical machine and electronic control. In powder grinding plant, ball grinding process flow includes crushing, milling,air classifying,packing,silos,bucket elevator,conveying,etc. Grinded material discharges from outlet grit fluently.
23-06-2020· One way of fully utilising the capacity of a ball mill is to convert it from an overflow to a grate discharge. This can allow an operation to increase plant throughput or reduce the product size, which can each contribute to higher revenue, but there are several factors to consider before the decision to convert is made.
The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill. AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill.
1. Add fine crusher before the grinding stage can reduce the particle size of grinding materials, thus effectively reducing the load of the ball mill and improving the productivity of ball mill. 2. Keep even feeding can guarantee the running state of ball mill, then improve the production capacity of ball mill. 3.
Media and Product Ball Mill Loading Guide. (Percentages are based on total volume of cylinder) NOTE: With media load at 50%, voids are created equal to 20% of cylinder volume. These voids are filled when product is loaded into the mill. Mills can be loaded by volume
