Chemicals: The attritor mill is used for grinding and mixing chemicals, producing fine powders and dispersions. Food: The attritor mill is used for grinding and mixing food ingredients, producing fine powders and pastes.
The circulation Attritor is used for difficult to grind and disperse materials and for the ultimate in micron size and quality. The main advantage of the "Q" series is the very narrow particle size distribution that can be achieved. Large quantities of material can be ground with a smaller investment of grinding media and Attritor equipment.
Important specifications when selecting grinding mills and pulverizers include, The size of the mill can range from pilot/lab to production,, to 1600 cu. ft. Feed size, material, and hardness of feed must be considered. Output size ranges. Mills can handle dry or wet input, or both.
HSA Series. The HSA High Speed Attritor is generally used in a continuous mode. The material is charged into the mill at the top and is discharged out the bottom side, making use of centrifugal force. The HSA is used when smaller particle size (generally 40 mesh) materials are fed into the machine and micron size end product is desired.
Grinding Media One of the key differences between the two is the type of grinding media they use. In ball mills, the media consists of metallic or ceramic balls that are used to crush and grind materials. In contrast, attritor mills use grinding media made of small metallic or ceramic beads.

Fig. 11 shows the stress energy averaged over 5 s of simulation for both the attritor mill and the planetary ball mill. Since the maximum difference of average stress energy between the planetary ball mill and the attritor mill is of 4 orders of magnitude, the semilogarithmic scale was used for Fig. 11.

Produce particles within narrow size rangesfrom 10 to 100 mesh. Attrition Mills from Munson Machinery are ideally suited for reducing fibrous and friable materials within a relatively narrow particle size range from coarse down to 100 mesh. Typical applications include materials that cannot be reduced by impact (hammer mills or pin mills) or by ...
Mechanical alloying for commercial production is carried out in ball mills of up to 3000 lb capacity (Fig. 5). The milling time decreases with an increase in the energy of the mill. For example, a process that takes only a few minutes in the SPEX mill can take hours in an attritor and a few days in a commercial mill.
MIKRONS ® Attritor is used for producing fine homogenous dispersions quickly repeatedly under controlled conditions. Used for the manufacture of ceramics, inks, paints,coatings, metal oxides, ferrites, chocolates, chemicals pharmaceuticals. The Attritor is often referred to as a agitated ball mill.
Highenergy milling parameters of a planetary ball mill using cylindrical vial [26]. Energy dissipated per hit versus the rotation speed of the planetary ball mill (Fritsch " Pulverisette 5 " [11 ...
Planetary Ball Mills 101 from Union Process Inc. Planetary ball mills share the same design as other basic ball mills a grinding jar filled with media and rotated on its own axis. But their unique design takes advantage of centrifugal force and the Coriolis effect to grind materials to a very fine or even micron size. These forces come into ...
Samples with 10 µm particle size were activated in The Fritsch Pulverisette 5 Ball Mill (Two Chamber Mill) at 400 rpm at different solid/ball ratios (1/10, 1/20, 1/30) and at different times (0 ...
The Attritor is a grinding mill containing internally agitated media. It has been generically referred to as a "stirred ball mill." A useful and simple equation describing the grinding momentum is M x V (mass x velocity), which enables us to see how the Attritor fits into the family of mills. For example, ball mills use large media, normally 1/2"
As this method often operates at lower rates than impact mills, with cooler temperatures, and with more respect for particle sensitivity, attrition milling is commonly specified for spices, seeds, and other products where maintaining the unadulterated nature of the material is paramount. It's certainly a challenge for a processor to know not ...
Difference Between Ball Mill and Rod Mill Rod Mills. The principal field of rod mill usage is the preparation of products in the 5 mm— mm (4 mesh to 35 mesh) range. It may sometimes be recommended also for finer grinding. Within these limits a rod mill is usually superior to and more efficient than a ball mill. The basic principle for rod ...
The Attritor's design accounts for much of the difference: conventional ball mills turn the entire drum or tank containing the media and the material, while Attritors stir the media in a stationary tank with a shaft and attached arms or discs resulting in a more efficient use of energy for the milling process.
attritor type, vibratory type, and tumbling type. In the vibratory type of ball mill, grinding of the materials can be performed with vibratory motions with high frequencies and low amplitudes. The ball's velocity in the vibratory milling apparatus is much greater than that of planetary ball mill system; there
Ball mills may be used for primary, secondary, tertiary and regrind applications. In the 1950s and 1960s ball mills dominated primary grinding, however they were supplanted in the 1970s by AG and SAG mill which also replaced two stages of crushing. ... The difference in the media properties leads to different breakage modes in these ...
The attritor, or stirred ball mill, is a grinding mill containing internally agitated media. There are quite a few types of attritors; they can be categorized as dry grind, wet grind, regular speed (to 400 rpm) and high speed (4001,800 rpm) attritors. A useful and simple equation describing the grinding momentum is M x V (mass x velocity ...
In summary, the main differences between a ball mill and an attritor are the design and construction, the grinding mechanism, the speed of operation, and the particle size achieved. Ball mills are more commonly used for larger particle sizes and in industries such as mining, ceramics, and paints.
milling processes, viz. planetary ballmilling and attritormilling, were employed to investigate the asmilled and sintered microstructure of the W7 wt.%Ni3 wt.%Fe (now onwards referred to as W7Ni3Fe) alloy. Thus, the focus of the present paper is to compare the milling behavior in the two types of mills and understand the

It was found that the ball mill consumed kWh/t energy to reduce the F 80 feed size of µm to P 80 product size of µm while stirred mill consumed kWh/t of energy to produce the product size of µm. It also showed that stirred mill produced finer product than the ball mill at around 40% lesser consumption of energy.
The "SC" Series Attritor meets this special processing requirement. Available with tank capacities ranging from 7 gallons to 245 gallons and horsepowers ranging from to 125, these powerful grinding mills feature a tapered tank to reduce load on the bottom arms for easy starting. A special lifter arm raises media and product off the ...
