1.The size and capacity of the mill
2. Type of material to be separated ( For example : kernel/shell or fibre/shell Separation ( the mill size)
Please make your order by email to director.engineer@yahoo.com :
DESIGN EXAMPLE :
Mill throughput : 60 tonnes/hr
Nut to FFB ratio : 12% (wet basis)
Air to cracked mixture ratio : 2.5 : 1 (by weight)
Air density : 1.18 kg/m3
Conveyor velocity : 16 m/s
Separation velocity : 11 m/s
System pressure : 180 mm W.G.
Efficiency of fan : 85%
Fan Capacity
Based on the data above, the calculation of fan capacity is as below,
Therefore,
Quantity of cracked mixture produced from ripple mill per hour,
= quantity of nut fed into ripple mill per hour = (mill throughput) X (nut to FFB ratio)
= (60 X 1000) X 0.12
= 7 200 kg/hr
Weight of air,
= (quantity of cracked mixture produced) X (air to cracked mixture ratio)
= 7200 / 2.5
= 18 000 kg/hr
Volume of air required = (weight of air) / (air density)
= 18000 / 1.18
= 15254.24 m3/kg
As 1.25 services factor required for extra air losses and leakage be appeared between the ducting and connection.
Hence,
Fan capacity = (volume of air required) X (service factor)
= 15254.24 X 1.25
= 19067.80 m3/hr
= 19068 m3/hr
Ducting Sizing
Below is a calculation to determine ducting diameter.
Therefore,
Pipe cross sectional area, A = (air volume required) / (conveyor velocity)
= 19068 X (16 X 60 X 60)
= 0.33 m2
Thus,
Diameter of pipe, D = √ (4A/π)
= √ (4 X 0.33 / π)
= 0.65 m
