Under the premise of ensuring the micro-negative pressure of the high-temperature fan outlet (two 20 to two 50 Pa), the valve 3202 should be opened as much as possible, and it is better to open it all. The purpose is to Let the hot air coming out of the kiln pass through the limestone vertical mill to dry the materials in the vertical mill.
In addition to raising the coal temperature inside the mill for drying and better grinding, the same air works as the transport medium to move the pulverized coal out of the mill: it travels through the annular space between the fixed trunnion tubes and the rotating hot air tube onwards to the classifier. Coal-laden air passes through double ...

Coal mill hot air inlet temperatures should never be more than 600 ° F and the outlet temperature should not exceed 200°F on Raymond coal mills If the flow of raw coal to the coal mill is interrupted for any reason (for example: plugging, failure of the coal feeder, etc), the outlet temperature of .
When LM series vertical mill plant works, main motor will drive the grinding disc with the reducer, meanwhile hot air coming into the mill via air inlet.Material fall into the center of cavity from feeding .
coal and reducing the air temperature. This minimizes the amount of fine coal dust subjected to hot air or hot equipment surfaces. The potential for fires is greatly reduced. Utilize a pulverizer air by-pass design to dry the coal with increased air mass flow rather than just air temperature.
The Hot Air Generators can be classified as. 1. Conventional type. A. Horizontal floor mounted type (Double Shell) B. Vertical standing type; 2. Fluidised bed type. Major Components of Horizontal Hot Air .
Vertical Roller Mill Operation. The motor drives the grinding table through decelerator. The materials fall down the center of grinding table from feed opening. At the same time, hot air comes into the mill from the air inlet. Due to the centrifugal force, materials move to the edge of the grinding table.
Working Principle. The motor of LM Vertical roller mill through reducer drive disc rotates, the material through the air lock feeder from the inlet falls central disc, while the hot air from the inlet into the mill.
