A diaphragm separates the two compartments and allows only particles below a certain size to pass to the second compartment. Ground material exits the mill through the discharge grate which prevents grinding balls from leaving the mill. A proportion of material, mostly fines, is „„air swept‟‟ out of the mill.

Deflectors can be switched 180° and therefore start a second lifecycle. This allows for constant classifying efficiency during the lining's lifecycle. Key Benefits: Liner weight reduced by 20 to 35% depending on mill diameter. E.g. for a mill in the 4.4 to 4.6m diameter range, weight is reduced by 465 to 310kg/m².

HPGR pre grinding and ball mill intermediate diaphragm grate design on grinding capacity of an industrial scale two compartment cement ball mill . Comparing ball mills and VRMS for cement grinding. The comparative advantages of ball mills and VRMs in cement grinding block the slots of the mill diaphragm World Cement is a portal to added value

By means of the open lifter diaphragm, the drying chamber integrated into the mill tube is separated from the grinding compartment. The steel grades used can easily withstand the up to 400°C hot gases found in the drying compartment.

The classifying lining provides efficient finer grinding of the coarse ground material. In the second compartment the material is primarily ground using pressure and friction, whereby the classifying lining retains the grinding balls with the largest diameter at the beginning of the compartment and the successively smaller balls at the end of the grinding path.

Water Spray in Cement Mills. Water spray installed generally in second compartment of ball mill to control cement temperature. Cement discharge temperature should be kept below about 110 o C but, the same time should allow some 60% dehydration of gypsum to optimize cement strength without excessive false set.

SAG Mill Liner Design Mineral Processing Metallurgy. To a more significant degree than in other comminution devices SAG Mill Liner Design and Configuration can have a substantial effect mill performance As with rod and ball mills liner designs for autogenous and semi autogenous mills have been in a state of flux for a number of years If the discharge …

Mills with central discharge are fitted with a double outlet diaphragm. The material is transported from both head sides of the mill towards the diaphragm, then out through the openings in the mill shell. For mills with central discharge (opposite material flow direction)

A diaphragm in the form of a composite sieving device for use in a rotary grinding mill containing loose grinding bodies for grinding solid materials is disclosed. The device comprises a sandwich structure which includes a plurality of plate-like members in intimate contact with one another. The plate-like members acting in combination prevent the passage of the grinding bodies and …

The size reduction takes place in a two- compartment tube mill; the first compartment of the mill is shorter than the second compartment. The coarse clinker is ground in the first compartment where larger balls (80, 60, 50 mm) are used and the fine grinding is done in the second compartment where smaller balls (below 25 mm) are used.

The two compartments are separated by a partition diaphragm. The specific power requirement of a two-compartment separator mill is about 5 % lower than that of a single-compartment mill. DOUBLE ROTATOR® The DOUBLE ROTATOR® (a central discharge mill) is used for grinding even the hardest and most abrasive materials.

I claim: 1. A one stage open circuit tube mill comprising a cylindrical body, a lining, grinding body, a feed port, an output port, a first partition means and a second partition means provided to separate the cylindrical body longitudinally into a coarse grinding compartment which is in communication with the feed port, a first fine grinding compartment being next to said first …

Two-compartment separator mill Two-compartment separator mills can accept ores with up to 30 mm lump size and 6 % moisture content. The grinding circuit has the same configuration as that of a single-compartment mill. The first grinding compartment (with lifter plate lining and large grinding media) is for coarse grinding.

1.2 Closed Circuit Mills These are usually two compartment mills : Compartment 1: For pre crushing of Clinker by larger size of grinding media Compartment 2: Fine – Grinding smaller size of grinding media • Once the material has gone through the mill it is transported to a separator where it is divided into two fractions.
