Plant Upgrades. The 2-Stage Koesep is specially developed for roller press (HPGR) applications. Using the HPGR in semi-finish grinding mode, overgrinding in the ball mill is reduced. This results in lower specific energy consumption and at the same time an increased production capacity of the grinding system.
High pressure roller press can be introduced as a pre-grinding step for the ball mill, in order to decrease specific power consumption in finish grinding and/or to increase the output of finish mill. Grinding capacity of finish mill increases by about 30%. Up to capacity increases are reported in India with the use of this approach.
The roller press consists of a pair of rollers set 0.25" to 1.25" apart rotating against each other, through which the feed is introduced and compressed at up to 300 MPa.

The equipment of ball mill used in cement plant includes vertical cement mill, roller press and ball mill, etc. The cement ball mill in cement plant is usually divided into 2-4 silos, the most representative of which are the "new type of high fineness cement ball mill" and "open flow high fineness cement ball mill".
A 10 MW cement mill, output 270 tonnes per hour. A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement. Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.
The two-compartment ball mill operating in a closed circuit with a high efficiency separator is thus still the most preferred arrangement for new cement grinding installations although the vertical roller mill now has emerged as a viable alternativedesign of closed circuit cement mill,process design of closed circuit vertical roller mill for ...
Plant 1 feed was the product of a wet AG-pebble mill circuit and the specific energy consumption was 39 kWh/ton. Plant 2 feed was the product of wet rod mill-ball mill grinding circuit with F 80 of about 20 mm. The energy consumption was 25.5 kWh/ton for this application. As given in Table 3, the HPGR circuit consumed 8 kWh/ton. These results ...
