The substitution ratios (ratio of the specific energy required by the ball mill to that required by the roll press at the same fineness) vary between 1.4 and 1.8 for cement. These figures obtained by means of the FCB-Index correspond to grinding energy values of ball mills under optimal conditions and therefore are minimum values.
Ball mill is mainly used for grinding in mining (metallic minerals and non-metallic minerals), cement, refractories, chemical, power plant, aluminum, building material, glass, ceramic, steel slag and fly ash, ect.

When grinding cement the abrasion of the ball mill is g/t while that of the roller press is 0.5g/t so it can meet the requirements of grinding white cement. Low Noise The noise of the ball mill is more than 110d while the cement roller press is about 80dB. Chat Online Cement Roller Press Roller Press In Cement Plant AGICO
The use of the high-pressure grinding roll for finish-grinding permits maximum energy sav-ings. In comparison with conventional ball mill grinding systems, up to 50 % of energy can be saved. Feed material with up to 6 % moisture content is dried in the separator. Material with higher moisture contents is dried in a separate
In this study, in order to evaluate and compare the performances of these cement grinding technologies, industrial scale data were collected from HPGR-ball mill, VRM, Horomill and multi-chamber ball mill closed circuits. The grind abilities of the raw materials of all circuits were varying in a narrow range of 14–20 kWh/t.
Roll presses are also used in, particularly in upgrading existing ball mill circuits as pre-grinders to increase production or to reduce specific power consumption in grinding operation. Ball mills for cement raw material and coal equipped with a drying compartment adequately air swept with hot gas (2.5-3.5M/sec above the ball charge), can ...

The cement roller press has a high energy utilization rate and remarkable energy-saving effect in the material grinding process. In cement plant, cement roller
Ball mills (Fig 1.1) are coming in cement plant areas of raw grinding, coal grinding and cement grinding which in turn as raw mill, coal mill and cement mill. Ball mills are horizontal tube mills having single or two compartments for grinding, Balls as …
FCB has just developed a new mill, HOROMILL ®, for grinding cement, raw meal and minerals.This new grinding process is designed for finish grinding and also for pregrinding. The energy saving is similar to the roll press, roughly 30% to 50% better than the ball mill, but with a moderate circulating load and grinding pressure.

The cement industry makes use of four mill types: the ball mill, the vertical mill, the roller press (also known as high-pressure grinding roll) and the horizontal mill. Grande, with the difference that both separators precede the roller press [9].
Reliable and effective grinding technology for diverse applications. With more than 100 years of experience in developing this technology. Outotec has designed, manufactured and installed over 8,000 ball and pebble mills all over the world for a wide range of applications.
The closed-circuit grinding system of the ball mill is shown as follows: materials mixed in a certain proportion will firstly enter the cement ball mill for grinding and then be sent to the powder concentrator by bucket elevator. The powder concentrator divides the materials into coarse and fine materials.
The grinding of the raw mix in a cement plant, can be carried out either wet or dry but because of the nature of the cement can, grinding it has to be carried out dry. Quality The quality expected will be the determinant of which ball milling process to be used.
with rods horizontal stone. ball grinding mill. L14 series. Rotational speed: 42 rpm - 69 rpm. ... Rod / Ball Mills are Rubber coated and manufactured in Double and Triple Roll models.
