Hopper Design Principles - Chemical Engineering .

For funnel flow hoppers, the outlet must be large enough to prevent a cohesive arch and stable rathole from developing. To prevent the formation of a stable rathole, the hopper outlet diagonal should equal or exceed the critical rathole diameter, D F. The critical rathole diameter is calculated by first determining the major consolidating pressure, σ 1, on the powder. In some cases, the ...

The mill outlet temperature of coal-air mixture is maintained between 65 to 90 degree centigrade in the case of low and medium volatile coal. In the case of high volatile coal, while the lower limit generally remains as 65 degree centigrade, the upper limit is restricted to a lower level depending on percentage of volatile content in coal. This is mainly done to avoid mill fire and mill explosion.
