Mill development led to the reform of powder industry
When the vertical roller mill machine is working properly, motor through reducer drive disc rotates, the material through the air lock feeder from the inlet falls central disc, while hot air from the air inlet into the mill. With the rotation of the disc, the material under the effect of centrifugal force, moving to the edge of the disc, the disc passes through the annular groove on the roller by rolling and crushing, the material crushed by the wind at the edge of the ring disc with high-speed air from large particles fall directly on the disc re-grinding, the material flow through the upper part of the separator, the role in the rotation of the rotor, meal bucket fell from the cone disc re-grinding, qualified powder together with a mill stream, through close dust collection devices, namely products, materials containing moisture in contact with the hot air in the process of being dried by adjusting the air temperature, the humidity of materials to meet different requirements, to achieve the required product water. By adjusting the separator can achieve the desired thickness of the different products.
Vertical milling machine is grinding mill machine equipment on behalf of the product, according to the conditioning tower and filter location, there are two different layout scheme, namely three fan system and dual fan systems. Product collected using a cyclone dust collector. This arrangement reduces the negative pressure system and work by the amount of gas precipitator. Electric dust collector can also be used as a final bag filter dust removal equipment; dust collection device can be used in electrostatic precipitator or a bag filter, the mill gas directly into the dust collector, the system reduces the number of equipment units simplify the system configuration.
Vertical milling machine three-dimensional structure, small footprint, complete and strong, finished powder expected from the block independent self-contained production system; finished powder fineness of uniform rate of 99% through sieve, which is the other milling equipment difficult to have; machine adopts airtight gearing and pulley gear box, transmission smooth, reliable operation; important parts are made of high quality steel, wear-resistant parts are made of high-performance materials, machine wear, reliable operation; Electric The system uses centralized control, milling workshop basic operations can be realized nobody, and easy maintenance.
