Re: Pulverized Coal Bin Design
Nobody can give u a figure for a D min it depends on a number of parameters (Material properties, wall friction, internal angle of wall friction etc.). Get your material tested for these properties then D min could be calculated. ■
Silo Opening
Dear Talreja
it is difficult to suggest solution based on application. you can provide rotary feeder or screw feeder.
In case your system requirement does not permit use of rotary feeder you can provide bunker bottom portion with polymer or ss liner. Pl donot provide opening less than 400 mm dia you can provide rack and pinion gate at hopper out let for reducing material flow rate

Discharge Of Fine Coal
It is possible to give a reasonably safe guide to the outlet conditions needed for this application, but to optimise the design one would need to measure wall friction and shear strength of the specific coal as the description -100 microns can cover a wide range of conditions. Considerations should also be given to the ambient temperature of the coal and the way that it is loaded intothe bin, particularly from empty conditions. The design of the screw feeder is also important. Ajax would be pleased to put forward a proposal for the feeder and advise on the bin design on receipt of the relevant information to lyn@ajax.co.uk ■
Pulverized coal bin design
Can any one guide me to decide the minimum opening of a coal bin of approx 100 Tons capacity, the throughput required is 45 Tons/hour, material is - Pulverized coal ( -100 microns ), moisture less than 2 %, the material of construction will be Carbon Steel, Is a mechanical agitator required at the discharge, Is air purging required, a screw feeder will be fitted at the discharge for the coal from the bin ■
