AIR CLASSIFYING MILL - MODEL EASY ACCESS
Model EA is the latest addition to the Mikro product line of milling equipment. The Model EA design can be
supplied with either independent or coaxial drives.
These mills are designed for applications requiring frequent product
changeover. The Model EA is designed for ease of access, removal of
components and ease of cleaning the internal surfaces of the mill.
The Model EA mill operates and performs the same as the
original Mikro ACM® - Air Classifying Mill, however the internal
components are designed to be removed quickly and easily. The
mill is designed with an internal liner assembly which stands
on its own in the grinding chamber and is not mechanically
secured. The shroud & baffle, liner assembly, classifier and rotor
can be easily removed to open the entire chamber area for
inspection and cleaning.
This model is unique in that it has an external coarse recycle system which extracts oversize material and returns it to the grinding chamber for additional processing. The feed design of the Model E introduces product from under the main rotor; ensuring that 100% of the feed material comes in contact with the impact rotor for optimal grinding efficiency.
It can also be used for grit reduction applications when tight particle top size control is required, such as in the case of Carbon Black, Iron Oxides, and Clays.
The processing of light density materials may become problematic as the lighter material will float in the classifier zone and will not easily be recycled to the impact zone of the mill. The external recirculation system of thethis model and the bottom feed ensure that all product is returned to the grinding chamber for more efficient size reduction.
Cohesive materials can in some instances stick and build up in the standard Air Classifying Mill, due to the expanded surface area of shroud and baffle assembly and the reduced tangential air velocity.
This model has no internal shroud and baffle and therefore no internal components to assist in accumulation of product. also the internal airflow is allowed to develop maximum velocity thereby keeping the mill chamber walls free from accumulation.
