The High Energy Ball Mill Emax and MM 500 were developed for grinding with the highest energy input. The innovative design of both, the mills and the grinding jars, allows for continuous grinding down to the nano range in the shortest amount of time with only minor warming effects. These ball mills are also suitable for mechano chemistry.
The ball mill splits the sample because of the hits against the balls. It moves along an arc of a semi circle due to the dragging of the pitcher in the cylinder motor. Isolated jars prevent the contamination of samples. Its function and design makes it suitable for mill works in laboratories of public
The widest ball mills in RETSCHs comprehensive range of ball mills comprises High Energy Ball Mills, Planetary Ball Mills and Mixer Mills. Whereas the Mixer Mills are used for dry/wet/cryogenic grinding and homogenizing small sample volumes, the Planetary Ball Mills meet and exceed all requirements for fast and reproducible Wet grinding Dry grinding Grind size Adapters for disposable vials ...
Ball mills designed for long life and minimum maintenance overflow ball mill sizes range from 5 ft. x 8 ft. with 75 HP to 30 x 41 . and as much as 30,000 HP. Larger ball mills are available with dual pinion or ring motor drives. Our mills incorporate many of the qualities which have made the Marcy name famous since 1913.
The first phase classification takes place right at the feeding point, the coarse and grits fall down in the air stream and shall go back to mill for further grinding via reject air slide. This separation saves a lot in term of pressure drop across the separator as well power consumption. The grits get separated from the fines before reaching LV pockets and rotor .

The second phase classification takes place in LV pockets due to velocity change and needs no energy to do that. This second phase classification removes a significant amount of coarse material before reaching the rotor for final separation. The 1st and 2nd phase classification reduces dust load going to the rotor and in return gives Low power consumption Low pressure drop High separation efficiency
Third phase of classification takes place at rotor. As most of the coarse is already separated in feeding point and LV pockets, the rotor has much less work to accomplish and consequently the separation efficiency is the maximum possible in present range of separator.
