It is going to go ahead in this way. Conveying the powder of coal ( sizing: 80 micron) with disc elevator ( powder flight conveying method).Capacity is 6 t/h and the density of powder it 500 kg/m3. Let me know if there is any problem or not. What about the explosion?

Dear Mr. Amir,

The arrangement of your equipment is not clear. Is it circular disc attached to the rope at the center and then this rope is moving in a loop form in two independent tubular casing? There will be many discs located at regular spacing. If your equipment is like this and your concern in only about the explosion, then how about using wooden / plastic disc instead of steel?

Bucket Elevator

Bucket elevator

May I have your opinion about my request

It is going to be checked some parameters in a Bucket elevator design. It is supposed that to handle coal powder (0-80 micron) up to 14m. Some modification should be considered to prevent explosion in it and I don’t know. Also in general consideration is there any wrong parameter in following or not?

Capacity: 6 tons/hour

Conveying speed: 0.6m/s

Power: 2.2 kw

Drum Dia.: 600 mm

Case dimension: 400x1000mm

Bucket volume: 2.1 lit

Distance between buckets: 400 mm

Belt width: 300 mm

Your bucket elevator seems to be going rather slow unless it is designed as a 'continuous bucket' type?

With coal you are likely to have an explosive atmosphere present internally. You should consider fire resistant, anti-static belting, belt slip monitoring and belt alignment monitoring.

You may also wish to consider explosion venting in the case that an explosion does occur (and venting to a safe area).
