Working Principle
This machine is really a skeleton pattern ball mill with horizontal cylindrical turning gear,drive by outer gear and two hopers.The fabric would go to the very first hopper following the spiraling by the quil shaft fro m the feeding equiment,The hopper has ladder sheathing or corrugated sheathing with steel ball s inside,that will fall under the result of centrifugal force by barrel embracing ram hard and grind material.Following the kibbling in the first hooper,by monolayer partition panel,the material will enter the second hooper,that has plane scale board with steel ball inside to grind material.The powder material will be discharge from the grid plate to finish the grinding.
Coal Mill Operation Process
Majority of coal is pulverized by coal mill before burning, usually 80% passing 200 mesh (75 micron). The coal mill functioning process and its effect goes as follow:
• Coal mill pulverizing increases the surface area
– Faster combustion
– More complete combustion
• Pulverizing also increases tendency to auto-ignite
• Raw coal does not present a deflagration hazard but fires in storage piles and silos are not unusual
– Fires usually occur around perimeter or near surface
– Sulphur and moisture are factors in stock pile fires, auto oxidation is the primary mechanism
BINQ coal mill operation process can be used in any degrades of coal milling industry.
