The FRITSCH Soil Deagglomerator almost completely automates the deagglomeration of soil samples and simultaneous removal of stones and a high sample throughput.
Field of application
Preparation of soil samples for chemical and physical analysis, e.g. to determine the active ingredients relative to crop yield or identification of pollutants. Agglomerates are reduced to 2 mm grain size, e.g. as per the sewage
sludge code or DIN 19683.
Method of operation
Agglomerated soil samples are crushed by the combined forces of impact and friction. Rotating spiral nylon brushes in a cylindrical grinding chamber gently deagglomerates the sample, simultaneously conveying the sample along a 2 mm perforated plate within the chamber. The processed sample is collected in a container at the base of the mill, whilst larger components (stones, glass, wood, etc.) are retained and finally separated out at the end of the grinding chamber.
Advantages
- Gentle deagglomeration
- No crushing of stones
- Automatic removal of components > 2 mm

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.

The Atritor Cell Mill is a highly efficient mechanical mill with multiple rotors mounted on a vertical shaft.
The construction is modular, providing great versatility for customised design.
It will produce material with mean particle sizes below 20 microns and can be fitted with an integral dynamic classifier if the control of top size is particularly important.
Product quality is optimised by control of mill speed through a frequency inverter, which also limits the starting current.
As an airswept mill this versatile unit is an effective flash dryer and, in some circumstances, can be fed directly with a slurry, producing a dry, fine powder.
Contact parts can be manufactured in many materials to suit most applications.
The Cell Mill is extensive in its applications, ranging from minerals through chemical, dyes and pigments to foodstuffs.

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.

The Sturtevant Micronizer® is a jet mill employing compressed air or gas to produce particles less than one micron. Inside the Micronizer, precisely aligned jets create a vortex. Material is fed into this vortex along an engineered tangent circle and accelerates. High-speed rotation subjects the material to particle-on-particle impact, creating increasingly smaller fines. While centrifugal force drives large particles toward the perimeter, fine particles move toward the center where they exit through the vortex finder.

The Atritor Opposed Jet Mill is probably the most efficient fluid energy mill available. Unlike many mills of this type, it directly entrains the feed material into the high pressure gas for maximum acceleration to near sonic velocity before two opposing streams impact directly in a compact grinding chamber.
The energy imparted to the accelerating particles is instantly expended in inter-particulate collisions and no energy is wasted.
Specific energy consumption is significantly lower than comparable systems.
The grinding chamber is lined with tungsten carbide for maximum resistance to abrasive materials.
An independent classifier is used to ensure the most efficient separation, uncompromised by interference from the grinding process. The oversize fraction is recycled to the grinding system.
Products with top sizes less than 10 microns and mean particle sizes of less than 2 microns are typical.
Dry, oil-free compressed air ensures an uncontaminated product. For heat sensitive materials the air is cooled or hot air will provide some drying capability.
The system is fully automated for un-manned operation.
Each plant is custom designed to specific performance requirements with individual line capacities up to 2t/h.
|
|
Application
Intensive industrial use
Reduction ratio: up to 20:1
Working principle
The feed is succed into the mill, when a fast rotating rotor generates a fan effect. The product is smashed by swing hammers on to the lining, bolted on the upper cover. A screen controls the final corn size.
