LM900 Vertical Roller Mill

LM900 Vertical Roller Mill

Overview
LM series vertical grinding mill is one advanced powder making mill through our engineer research & experience and bringing in advanced technology of the world. It is ideal equipment for superfine milling industry which integrated with crushing, drying, grinding and collecting. It is widely used in cement, power, metallurgy, chemical, non-metallic minerals industry .Vertical mills are mainly used for comminuting lump, granular and powdered materials into specified size powder. When buying grinding mill through GUIKUANG, customer benefits from high output, low power consumption, wide-rang applications, easy operation, stable performance, simple structure, small vibration and low running noise. LM vertical mill is a good solution for the industry grinding mill’ technical problems, such as low output, high power consumption and strong noise ,etc.
Working Principle of Superfine Vertical Mill
Motor runs under the condition that tapered planetary gear reducer drives nether millstone. The materials fall into the center of device through screw conveyor, and hot air comes into the mill through air inlet. With uniform rotation of the millstone , the materials ,under the function of centrifugal force, move to the edge of millstone and comminuted by hydraulic tension of millstone when they come by annular chute. The grinded material will be taken up by high-speed air circulation from the air inlet. When the material in the airflow go through blade classifier, under the action of centrifugal force of rotating rotor, the bigger powder will fall down for regrinding and the qualified powder will be collected by collecting device as to be final product. Materials containing water will be dried when they contact with the hot air. Different humidify materials can be dried to the requirement through adjusting the temperature of hot air. Adjusting the rotating speed of driving system, separator and blower can get the required fineness powders.
