1, Base aggregate feeding system
A. general introduction of ground feeding system of aggregate
Cold feeding system is fixed in front of drying, which is used for
storing aggregate of different diameters.
Below each hopper, there is separate belt feeder, feeding certain
amount of aggregate onto the long belt conveyor under hoppers
according to the ratio.
Feeding amount of belt feeder is controlled and adjusted by
transducer adjusting motor speed, combining with appropriate
opening degree of feeding door.
The hoppers need to be maintained by visual inspection in case of
abrasion and damage, once necessary, carry out proper maintenance.
B. Wall vibrator
It's often happened that hopper is difficult to empty wet aggregate
or sand, then to install a wall vibrator is necessary to avoid
discharging difficulty. The vibrator is a special electromotor,
which has eccentric block to generate vibration, and is controlled
by time-adjust program. The parameter of vibration is presetted and
amplitude-change is not needed to adjust. Please consult to the
manuals provided by relevant electromotor manufacturers for
Maintenance for cold feeding system of batch type hot mixing
asphalt drum plant
a. Usual faults elimination of cold feeding system
⑴. Feeding not freely
Sundries in cold hoppers.
Aggregate is too wet and agglomeration occurs.
Wall vibrator works abnormally.
⑵. Daily maintenance
Grease all bearings according to their cycle. refer to
Check belts for abrasion and rupture, and replace them in time.
Belts cannot be polluted with grease or machine oil. Remove any
Keep driving chains tensioned properly, and lubricate them
according to schedule.
Check supporting roller for agility.
n. Electromotors and reducers
Refer to manufacturer specification.
