LUM series of ultra-fine vertical roller mill mainly consists of motor, reducer, roller device, disc apparatus, pressure equipment, separator, body and petrol stations and other components. It turned out to make a one-time completion of superfine powder grinding, grading and transfer operations of the idea of ??reality, the process parameters, mechanical properties and finished powder quality and other technical indicators are comparable level with Taiwan. Multi-rotor separator: 1. Each rotor frequency control; 2. No low-grade material, a winnowing demand can be achieved fineness;
Auger feeder: to ensure stable feeding center. Superfine vertical milling machine structural characteristics
Superfine vertical milling machine structural characteristics of the three inlets: to achieve full access to the air flow.
Double cylinder: precise control of the pressure roller. Superfine vertical milling machine structural characteristics
Vertical milling machine structural characteristics of ultra-fine frequency control motors: adapt extensive material.
Working principle
Driven by the main motor reducer rotating disc, while wind from the air inlet into the LUM superfine vertical mill, the material to the next through the screw feeder spout landed central disc, the centrifugal force of the material from the disc center to the edge evenly moving through the area when the grinding disc on a roller by rolling mill rolls, bulk material directly crushed fine material is formed after the extruded material bed intergranular pulverization. Crushed material to the disc edge continues to move until it is taken away by the strong airflow at the air ring, while the larger particulate material again fall on the disc continues to crush, airflow through the upper portion of the material in the separator, the rotor the role of the blade, coarse grinding disc back on qualified powder together with the air out of the grinding, is collected powder collector system, it is collected in vertical mill ultrafine powder is milled products. When mixed into the mass of iron and other debris along with material moved to the edge of the disc, which can not be due to the large wind from its own weight, fall to the mill to be installed at the bottom of the lower chamber disc scraper plate scraped into slag discharge port outside the machine .
