The CryoMill has been specially designed for cryogenic grinding. The grinding jar is continually cooled with liquid nitrogen from the integrated cooling system before and during the grinding process.
Thus the sample is embrittled and volatile components are preserved. The liquid nitrogen circulates through the system and is continually replenished from an autofill system in the exact amount which is required to keep the temperature at –196 °C. The automatic cooling system guarantees that the grinding process is not started before the sample is thoroughly cooled. This results in reduced consumption and guarantees reproducible grinding results.

The Atritor DCM Mill is one of the most universal milling systems available with independently driven grinding and classifying sections.
It has a wide range of applications producing materials in some instances to less than 15 microns.
Feed material is metered into the mill pneumatically and first passes into the classifier zone where any fraction of the feed that is already inside specification is removed as product, thus avoiding any over-grinding. Oversize is recycled internally to the grinding zone and is returned to the classifier after further size reduction. This process produces a steep size distribution curve.
Adjustment of the classifier speed controls the size of the product leaving the mill. The product is conveyed pneumatically to a collecting cyclone and/or bag filter. With the application of heat to the inlet air flow, simultaneous drying can be undertaken.

Ball mills are used primary for single stage fine grinding, regrinding, and as the second stage in two stage grinding circuits
Grinding of materials in a tumbling mill with the presence of metallic balls or other media dates back to the late 1800's. Since that time, Metso
Minerals and its predecessor companies, MPSI, Sala, Marcy, Hardinge, Kennedy Van Saun (KVS), Denver Equipment, Allis Chalmers, Boliden
Allis, and Dominion Engineering, have designed and manufactured more than 8,000 grinding mills.
Metso overflow ball mill sizes range from 5 ft. x 8 ft. with 75 HP to 26 ft. x 41 ft. with 20,000 HP.
Normal feed size to a Metso Minerals ball mill is 80% passing 1/4" (6mm or finer) for hard ores and 80% passing 1" (25mm or finer) for soft ores.
Product size is typically 35 mesh or finer.
Operation
Ball mills operate either in open or closed circuit. Open circuit operation is best utilized when:
Another stage of grinding follows the mill
Reduction ratio is small
Feed material is already fine and one pass through the mill produces the desired results
Product size control is not critical and oversize material can be tolerated in the product

Ball mill is an efficient tool for grinding many materials into fine powder. The Ball Mill is used to grind many kinds of mine and other materials, or to select the mine.2 It is widely used in building material, chemical industry, etc. There are two ways of grinding: the dry way and the wet way. It can be divided into tabular type and flowing type according to different expelling mine.
To use the Ball Mill, the material to be ground is loaded into the Neoprene barrel that contains grinding media. As the barrel rotates, the material is crushed between the individual pieces of grinding media that mix and crush the product into fine powder over a period of several hours.
Quite simply, the longer the Ball Mill runs, the finer the powder will be. Ultimate particle size depends entirely on how hard the material you're grinding is, and the time how long the Ball Mill runs. Our Ball Mills have been used to grind glass, powder food products, creat custom varnishes,make ceramic glaze, powder various chemicals, and make Black Powder.
1) Easy and safe operation
2) Stable performance
3) Even product size
4) Low energy consumption
4) Low invest, high return

With the proven use of gearless drive technology, the limitation of AG/ SAG mill size due to gearing constraints has been eliminated. Metso Minerals is the world's leading supplier of gearless AG/SAG mills.
The experience gained from installation and operation of these mills enables us to offer mills of up to 35,000 installed horsepower or more.
Today a single grinding line with a Gearless SAG mill and appropriate ball mills can process over 100,000 mtph.
Gearless AG/SAG Mills
Gearless drives (ringmotors) have been used on tumbling mills for several decades. The design features motor rotor elements bolted to a mill shell,
a stationary stator assembly surrounds the rotor elements, and electronics covert the incoming current from 50/60 Hertz to about 1 Hertz. The mill
shell actually becomes the rotating element of a large low speed synchronous motor. Mill speed is varied by changing the frequency of the current to
the motor. The ringmotor can be used to inch and spot the mill for maintenance.
Our engineers welcome the opportunity to assist you with circuit and circuit control design as well as start-up, operation, and optimization of the milling plant.

Fives FCB owns a remarkable tool for mill sizing, in the form of a grindability test so-called "FCB-Index" simulating for the best the grinding in a tube mill. Indeed, Fives FCB has developed and improved for many years a precise basic grindability batch test needing less than 50 kg of material and which makes it possible to define:
The specific energy necessary to grind a given material when using an optimised closed circuit grinding plant with a modern separator
The characteristics of the finished product which will be obtained in the a.m. industrial optimised circuit
The corrective solutions allowing to reach the optimum performances from an existing industrial grinding plant.
Using this tool, Fives FCB is capable to size a new grinding installation or to define the modifications of an existing one, with the determination of their expected performances (ref. "Modelling of grinding plants and grindability of materials in cement plants" - G. Flament, V Saint-Etienne, A. Cordonnier, P. Tête - World Cement 1991, Vol 22, n° 8, pp 14-26).
