Start smoothly&ratio control hot mix asphalt plant with
anti-bonding conveying belt with sweeper
Steps for setting of control system for batch type asphlt mixign
Before mixing, it is required to set the following formula
a. Hot aggregate formula storage. (see the following menu)
The ration of Maxi(NO5cabinet)； Unit:1％
The ration of coarse(NO.4 cabinet/bin)； Unit:1％
The ration of medium(NO.3 cabinet)； Unit:1％
The ration of fine(NO.2cabinet)； Unit:1％
The ration of sand(NO.1cabinet) Unit:1％
The ration of lime filler Unit:1％
The ration of added filler. Unit:1％
The ration of asphalt. Unit:0.01％
Mixing time Unit:S
At the monitoring menu, click the symbol formula keyboard,you can
enter the formula storage menu.
At the upper figure, click the menu ‘add formula’, you could enter
the calling menu of hot aggregate formula.
b. Cold aggregate formula storage.
The ration of NO.1 cold cabinet unit:1％
The ration of NO.2 cold cabinet unit:1％
The ration of NO.3 cold cabinet unit:1％
The ration of NO.4 cold cabinet unit:1％
The ration of NO.5 cold cabinet unit:1％
At the upper figure, click the menu ‘cold aggregate formula’, then
you could enter the calling menu of cold aggregate formula.
At the upper figure, click ‘add formula’, you could enter cold
aggregate formula storage menu. (described as the following figure)
c. Set the preseted value of aggregate, filler, asphalt etc.(see
the following figure)
The preseted value of aggregate, filler, and asphalt is the
benchmark of automatic ration, and the computer according to
overweight will correct the secondary ration automatically.
d. Preset slow discharging of hot aggregate.
The system has cursory and meticulous metering mode. The preseted
parameter is the threshold value for the cursory metering to be
stopped during ration. For example, if the needed material is 200
kg, and the presetted slow discharging parameter is 50 kg, then,
the cursory metering door will close when it reaches 150 kg and the
meticulous metering will continue. In this way, we could gain
better weighing precise.
⑸. Operate and control ignition of the burner
Before igniting, be sure that the control system is started fully
and without fault firstly, and then ignite.
The operation of the burner refers to user’s manual for details.
⑹. The start-up of cold bins and feeding adjustment.
a. After system booted and burner ignited, click cold aggregate
icon,enter cold feeding menu (see the following figure).Choose the
preseted formula, input the value of weight(t/h) actually used, click ‘ST’, the feeders will be started in sequence
according to the dosage of each bin.
|1||Slope belt conveyor/ inclined belt conveyor||driving drum||1|
|2||driving sprocket wheel||P=25.4||1|
|5||driven sprocket wheel||P=25.4||1|
|7||conveyor belt||B=800 L =25000||1|
|8||lower support roller||φ76 L=895|
|9||upper support roller||φ76 L=280|
