CEV504 – PARTICLE AND BULK MATERIAL HANDLING
CASE STUDY
The design system must combine the hopper (as the feeder) and pneumatic pipeline
(combinations of both horizontal and vertical) section. You are provided with a collection
of data to support your design consideration. At the end of the findings, include the
followings in the summary:
A conical hopper is directly connected to the pipeline of the pneumatic system. The hopper serves
as a temporary storage of the dust and also as a feeder to feed the dust directly into the pipeline.
Shear cell test on the food particle give the variations of following information:
The pneumatic dust collection system will connect to only one receiving bin which is 3500 m away
from the dust collection facility and to be installed at 3 m to the basement. The system uses a
positive pressure pneumatic transport system which is able transport dry dust particle of the
following ranges of:
a. 150 mm
b. 300 mm
c. 450 mm
Additional data:
gas friction factor of 0.005,
density of gas = 1.5 kg/m3
viscosity of gas = 25.1 x 10-6 Pa.s.
voidage in the pipe at choking velocity = 0.9980
The following data are provided to estimate the friction factor of the particles:
Conical hopper
Advantages and disadvantages of mass flow of a conical hopper
Philosophy of hopper design
Environmental application of hopper
Definition of pneumatic conveying
Philosophy of pneumatic transport design
Environmental application of pneumatic conveying
Advantages and disadvantages of pneumatic conveying
Major components in pneumatic conveying systems
Characteristics of sustainable dust collection system (compare with current method of
waste collection)
All information must be reported in paragraph, supported with related diagram and pictures.
Include as Section 1: Introduction of dust collection system (hopper and pneumatics) and its
applications.
Illustrate the overall pneumatic system by providing a schematic diagram of the design
system (include with hopper)
Highlight the major components involve and explain its function.
Explain how your design system works in collection and transfer of dry dust to the
receiving bin
Summary of design details:
i. Specify one constant value of:
- Mass flow rates of solids
- Bulk particle size
ii. Horizontal length
iii. vertical length
iv. Number of bends and its angle
v. Friction factor, fP
vi. Pipe size
vii. Saltation velocity
viii. Total system pressure loss
All findings must be supported with relevant calculation steps and assumptions. Include all
information in Section 2: Hopper and Pneumatic Transport Design System
i. Justify the selection of the semi-included angle and critical outlet diameter to give
mass flow.
ii. Justify the calculated and allowable pressure loss in pneumatic system.
From the calculation made in task 2, propose with justification of the hopper outlet diameter and
pipe diameter selection. Provide a summary of design details of the selection. Justify your
answer and report the comparison in Section 3: Comparison study.
