The overflow type of Ball Mill is designed to overflow and discharge materials from the trunnion on the outlet side. By combining it with a mechanical classifier or wet-processing cyclone, you are able to extensively use this type for grinding in closed circuit or for special applications such as re-grinding in open circuit.

Three surveys were carried out with the mill operating under different solids concentrations. In each of these surveys, samples of the fresh feed, the overflow and underflow from the hydrocyclones, and the discharge of the ball mill were collected in 15 min increments for two hours during a period of stability of the circuit . Size analysis and ...

Overflow discharge mills are used when a product with high specific surface is wanted, without any respect to the particle size distribution curve. Overflow discharge mills give a final product in an open circuit. Grate discharge mills are used when the grinding energy shall be concentrated to the coarse particles without production of slimes.

are grate discharge and ball mills are mostly overflow (a few, however, are grate discharge). In overflow mills the belly length inside liners, which is what the model requires to be input, is very close to the flange-to-flange length. In grate discharge mills it is the length as measured from the inside face of the

The ore discharge of overflow type ball mill mainly depends on the pulp itself high over the lower edge of the hollow shaft bushing. 2. Performance and application differences between grid type ball mill and overflow type ball mill. Compared with the overflow type ball mill, the ore discharge of grid type ball mill is low-level forced discharge.

The lack of constraints in ball mill capacity in the published ball mill models may result in unrealistic predictions of mill throughput. This paper presents an overfilling indicator for wet overflow discharge ball mills. The overfilling indicator is based on the slurry residence time in a given mill and given operational conditions.

Overflow ball mill is a kind of ball grinding mill which works in wet water state. It belongs to a type of wet ball mill and is a very common grinding equipment in the concentrator. Ball grinding mills are classified according to the discharge methods and can be divided into overflow ball mill and grate ball mill.

Grate discharge Dry Grate discharge Wet Overflow discharge Wet Figure 8.5 Effect of mill filling on power draft for ball mills. The data is taken from Rexnord Process Machinery Reference Manual, Rexnord Process Machinery Division, Milwaukee, 1976 The effect of varying mill speed on the power drawn by the mill is shown graphically in Figure 8.4

Overflow Discharge Ball Mill. Furthermore The Ball Mill Of A Large Capacity Has Been Available To A Very Extensive Range Of Applications In Both Dry And Wet Processing Features Overflow Type The Overflow Type Of Ball Mill Is Designed To Overflow And Discharge Materials From The Trunnion On The Outlet Side

The slurry of overflow type ball mill is discharged automatically through the discharge port, while the grid type has the function of forced discharge because of the grid plate, so as to increase the processing capacity and reduce the over crushing of ore.

Ball mill is a essential equipment for further grinding the material after it is crushed. It continues to grind minerals by grinding media to reach a certain fineness to achieve a better grinding effect. Most of mines use overflow ball mill. The mineral will gradually flow to the discharge end with the rotation of the cylinder and the movement ...

WORK PRINCIPLE. ball mill could wet grind and dry grind many kinds of minerals and grindable material, according to different ore discharge methods, there are grid type and overflow type ball mill. High manganese steel plate is more wear-resisting and it has longer service life.

Main Technical Parameters of Wet-Grinding Overflow-Discharge Rod Mill. Note: 1. The cylinder diameter refers to the internal diameter of the cylindrical section, and the cylinder length refers to the effective length of the cylindrical section. 2. The …

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.

Discharge of pebbles, finer rock, ball scats and slurry from mills and its flow through trommels, and into other processing operations has strong impacts on overflow ball mill performance.

The discharge port may be covered by a grate to prevent oversized ore exiting the mill, or it may have no grate (overflow type ball mill). As the balls wear due to abrasion, they are replaced with new balls ('green' balls). If large particle sizes are retrieved from the ball mill, the process is known as a 'coarse grind'.

For an overflow discharge ball mill, the gross slurry pool volume can be calculated from the mill geometry data (mill radius, length, trunnion radius) and the slurry level. In the slurry pool, the immersed ball media occupy space and reduce the effective volume for slurry to be held in the pool. On the other hand, in a rotational ball mill, the ...

The overflow mills use much simpler trunnion bearings to support the mill, whereas grate-only discharge mill would require a tire gear around the shell which is expensive and involves complex manufacturing process as the grate has to withstand the pressure exerted by the steel ball charge and allow slurry to discharge effectively."

Overflow discharge ball mill can grind ores into the size under 0.2 mm, so it is very suitable for the second grinding system. The capacity of it is about 15% lower than grate discharge ball mill in the same specification, and the loaded grinding medium is …

Converting a ball mill from overflow to grate discharge involves installing a grate inside the mill at the discharge end. The grate holds the balls inside the mill but allows the slurry to pass through, and it is then pumped out of the mill by the pulp lifters.
