Generally, filling the mill by balls must not exceed 3035 of its volume. Productivity of ball mills depends on drum diameter and the relation of drum diameter and length. Optimum ratio between length L and diameter D, L D is, usually, accepted in the range 1.561.64.

Jan 22, 2020 Shaft depth and mill throughput data. Full profiles of select mines and projects. Heavy mobile equipment. HME type, model, size and quantity. ... The combined product goes to the ball mill sump before cycloning. The coarse cyclone product is directed to the ball mill. Milling is
The BondMill Throughput spreadsheet was designed to estimate the Grinding Capacity of a given mill of known dimensions and operating conditions - Net Power Draw in particular - based on the traditional Bonds Law and the Hogg amp Fuersteneau Power Model see Mill PowerBall Mills spreadsheet for further details on such model.
The SAG mill 7.925 m . diam. x 3.734 m . long 3,650 KW operates together with a ball mill 5.486 m diam. x 8.839 m long 4,474 KW to reduce the ore to about 80 passing 60 m to 85 m, depending on the ore type and its hardness. The ball mill operates in closed circuit with cyclones. About
measure both ball load and pulp slurry positions inside a running mill. The main data are provided in terms of toe and shoulder angles. Figure 6. The pulp density is an important parameter which influences the grinding efficiency. In iron ore, for instance, a variation of 2

The ... functions are designed to use plant historical data to automatically assist engineers and technicians in the assessment of loop performance, the ...
of the cyclone underflow back to SAG mill, introduction of a second classification stage as well as introduction of a second ball mill. The evaluation of breakage tests and survey data revealed the following the Bond work index obtained for the current ore ranges between 17.20 -
Mill Power Draw Models. The mill power draw models are used to predict how much power will be consumed by a particular type of mill, mill geometry and set of mill operating conditions. This power is transferred to the ore and used to predict the throughput when combined with the specific energy consumption models.
geometallurgy and multi-scenario simulation in the design of a circuit featuring AGSAG mills. The method relies in using statistics to analyze geometallurgical and mining data to model the variability of specific energy requirements of SAB SAG and ball mill and SABC SAG and ball mill with-pebble
Aug 01, 2019 The laboratory ball mill 305 150 mm used for this wet grinding is shown in Fig. 3, it mainly formed of a motor, an inverter, a mill shell, a torque sensor and a data acquisition system. The mill shell was constructed from a steel drum, mounted on the mill shaft, and lined with 12 pieces of trapezium lifters equally spaced.
To prevent spillage and overload, the control scheme must allow the ball mill circuit to accept almost any amount of feed rate without overload. At high feed rates, this will compromise the grind size, so the SAG mill feed rate limits must be managed to ensure the right grind size versus throughput tradeoff is
Single stage SAG Mills are very beneficial in reducing CAPEX for plants with a staged throughput approach. When future tonnage is to be increased, the SAG Mill can feed downstream ball milling to boost capacity. Fuller-Traylor SAGAG Mills range in size from 4.3m through 12.2m in diameter with powers as high as 28,000 kW.

Using composite liners also cuts the weight of the liners to about 50 percent of standard steel cast liners, making it possible to work with a higher ball charge level without increasing the total weight of the mill. Both of these benefits result in a higher throughput. The higher throughput must be considered over longer periods of time.
Hello Dear Friends, We are working in a plant with single stage grinding using three parallel wet three compartment ball mill. Each ball mill operates in a close circuit with Classifier. The fineness of ball mill product is OK so the circulating load is insignificant 44 Kgh. The overall data of

Davis data infers a relative throughput of 2.3 against the open circuit at 500 circulating load where the model only predicts an increase in relative throughput to 1.83. When the bond baseline C1 2.5, E1 100 is considered, Davis ... in the product of the ball mill, reduces the throughput of the circuit. It
The Bond ball mill work index BWI data were used to determine the ball mill power requirement. Table 1 summarises the 75th percentile values for the various comminution parameters used to determine plant throughput and mill power draw. A more complete list of comminution data is provided in Appendix 1.
