Designing a Screw Conveyor for Modulling Sand
Bulk Density and Loading Efficiency
The bulk density of sand is given as 1.6 tonne/m^3. Loading efficiency is 0.125, which means that only 12.5% of the available volume will be filled with sand.
Capacity and Length of Conveying
The required capacity is 60 tonne/hour, and the length of conveying is 25 meters.
Inclination and Inclination Factor
The screw conveyor is to be designed to convey sand at an inclination of 20 degrees with the horizontal. The inclination factor is 0.65.
Screw Pitch and RPM
The screw pitch is equal to the nominal screw diameter. The RPM is 50.
Progress Resistance Coefficient
The progress resistance coefficient is given as 4.0. This value is used to determine the power required to move sand through the conveyor.
Diameter Calculation
To calculate the diameter of the screw conveyor, we can use the formula:
D = 1.15 * (Q / n * K)^0.5
Where,
D = Diameter of the screw conveyor
Q = Mass flow rate in tonne/hour
n = RPM of the screw conveyor
K = Progress resistance coefficient
Substituting the given values, we get:
D = 1.15 * (60 / 50 * 4)^0.5
D = 0.81 meters
Therefore, the diameter of the screw conveyor required to convey sand at an inclination of 20 degrees with the horizontal is 0.81 meters.
Power Calculation
The power required to move sand through the conveyor can be calculated using the formula:
P = (Q * H * SG) / (K * η)
Where,
P = Power required in kW
Q = Mass flow rate in tonne/hour
H = Total conveyor height in meters
SG = Bulk density of sand in tonne/m^3
K = Progress resistance coefficient
η = Mechanical efficiency of the system
Substituting the given values, we get:
P = (60 * 25 * 1.6) / (4 * 0.65)
P = 692.3 kW
Therefore, the power required to move sand through the conveyor is 692.3 kW.
Bulk Density and Loading Efficiency
The bulk density of sand is given as 1.6 tonne/m^3. Loading efficiency is 0.125, which means that only 12.5% of the available volume will be filled with sand.
Capacity and Length of Conveying
The required capacity is 60 tonne/hour, and the length of conveying is 25 meters.
Inclination and Inclination Factor
The screw conveyor is to be designed to convey sand at an inclination of 20 degrees with the horizontal. The inclination factor is 0.65.
Screw Pitch and RPM
The screw pitch is equal to the nominal screw diameter. The RPM is 50.
Progress Resistance Coefficient
The progress resistance coefficient is given as 4.0. This value is used to determine the power required to move sand through the conveyor.
Diameter Calculation
To calculate the diameter of the screw conveyor, we can use the formula:
D = 1.15 * (Q / n * K)^0.5
Where,
D = Diameter of the screw conveyor
Q = Mass flow rate in tonne/hour
n = RPM of the screw conveyor
K = Progress resistance coefficient
Substituting the given values, we get:
D = 1.15 * (60 / 50 * 4)^0.5
D = 0.81 meters
Therefore, the diameter of the screw conveyor required to convey sand at an inclination of 20 degrees with the horizontal is 0.81 meters.
Power Calculation
The power required to move sand through the conveyor can be calculated using the formula:
P = (Q * H * SG) / (K * η)
Where,
P = Power required in kW
Q = Mass flow rate in tonne/hour
H = Total conveyor height in meters
SG = Bulk density of sand in tonne/m^3
K = Progress resistance coefficient
η = Mechanical efficiency of the system
Substituting the given values, we get:
P = (60 * 25 * 1.6) / (4 * 0.65)
P = 692.3 kW
Therefore, the power required to move sand through the conveyor is 692.3 kW.
