It is an air-swept by an air current Mill, which drags the particles produced in the grinding chamber to a high efficiency dynamic type classifier where the fine cut is removed without disturbing the grinding of the coarse product. This coarse product enters the grinding chamber automatically and at a controlled rate according to the power consumed by the Mill motor or by the fan motor. Achieving fineness between 25 microns (500 mesh) and 150 microns (100 mesh).
Due to the technology, hardness and simplicity of those pendular mills, they are a more economic solution than the hydraulic vertical mills if we talk about small productions. Achieving a cost reduction of 50%.
CHANGE OF FINENESS INSTANTLY
The changes of the fineness is carried out at distance with the mill running and in a very easy way from the control panel.
FEED AUTOMATIC CONTROL
Feed rate is adjusted automatically with the mill capacity, that is, increasing or reducing it according to the production, for it, the mill and main fan consumption’s are taken into account.
The whole plant is practically under negative pressure, in such a way that although there are openings in the air circuit, dust does not get out to the outside ambient. Furthermore, all the circuit breathes through a bag filter.
SIMULTANEOUS DRYING AND GRINDING
These plants are designed to have the possibility of a simultaneous drying, when the product moisture content so requires it, making in this way the production costs quite more economic. This option is very interestig if our aim is to grind mineral fuels as coal or petcoke.
