Closed circuit ball mill with two compartments for coarse and fine grinding and a drying compartment with lifters are generally found in cement plants for raw material grinding. Compartments (filled with grinding media) are divided by a double diaphragm with flow control to utilize maximum mill length for effective grinding.

Ball mills with high efficiency separators have been used for cement grinding in cement plants all these years. Ball mill is a cylinder rotating at about 70-80% of critical speed on two trunnions in white metal bearings or slide shoe bearings for large capacity mills. Closed circuit ball mill with two compartments for coarse and fine grinding ...

Grinding circuits are fed at a controlled rate from the stockpile or bins holding the crusher plant product. There may be a number of grinding circuits in parallel, each circuit taking a definite fraction of the feed. An example is the Highland Valley Cu/Mo plant with five parallel grinding lines (Chapter 12).

Metallurgical ContentOpen Circuit GrindingClosed Circuit GrindingGrinding Circuit Process Control VariablesGrinding Operating Costs The simplest grinding circuit consists of a ball or rod mill in closed circuit with a classifier; the flow sheet is shown in Fig. 25 and the actual layout in Fig. 9. This single-stage circuit is chiefly employed for coarse grinding when a product finer than 65 ...

For this purpose, influences of 250, 350 and 450 g/t of dosages of an amin-based commercial GA on the cement grinding circuit was compared with the condition in which GA was not used. The effects of GA dosage on the ball mill and air classifier were examined in detail considering the change in the residence time of the material.

Mill Type Overview. Three types of mill design are common. The Overflow Discharge mill is best suited for fine grinding to 75 – 106 microns.; The Diaphram or Grate Discharge mill keeps coarse particles within the mill for additional grinding and typically used for grinds to 150 – 250 microns.; The Center-Periphery Discharge mill has feed reporting from both ends and the product discharges ...

Cement milling Question 34. We operate one open circuit two chambers ball mill of size 4m dia X 13.5m long for Cement grinding. Capacity:100tpd drive motor: 2x1500 kW (twin drive) Power drawn: 2500 kW (more data on grinding media). >We are maintaining a blaines of 2700 to 2800.

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.

01-11-2017· Cement Mill Grinding Media. Dear Experts, I want to know about the GM size wise percentage distribution in a 2 chamber close circuit OPC ball mill. Mill dim. 3.4 x 12.5. Media load 128 MT high chrome. Also let me know how do the supplier selected 80mm as max. Ball size in this mill? Please share the formula as well.

There are efficiency factors for dry grinding, open circuit ball milling, mill diameter, oversize feed, grinding finer than 75 microns and too large or too small reduction ratios. For cement application, the dry grinding (EF1), mill diameter (EF3), oversize feed (EF4) and fine product (EF5) factors are relevant.

to the volumetric mill filling which influences grinding media wear rates, throughput, power draw, and product grind size from the circuit. Each of these performance parameters peaks at different filling values. In order to contin-uously optimize mill operation, it is vital to obtain regular measurements of the ball load and pulp position.

For this purpose, influences of 250, 350 and 450 g/t of dosages of an amin-based commercial GA on the cement grinding circuit was compared with the condition in which GA was not used.
