What is the difference between LB Series and DHB Series Asphalt/bitumen Plant?

1. Mixing system:

LB series is batch mixing type, using forcing mixer to mix, mixing asphalt is much more equably than DHB series.

DHB series is continuous mixing type, using drum mixer to mix.

2. Weighing system:

LB series with accurate weighing system for aggregate and bitumen and filler…, so asphalt quality is much higher.

DHB series with rough weighing way.

3. Vibrating screen:

LB series vibrating screen to make sure the aggregate size accuracy.

DHB series without screen.

4. Design:

LB series design is perfect, and with higher quality.

DHB series design is simple, and with lower cost.

5. Capacity:

LB series: 40t/h-400t/h.

DHB series: 20t/h-100t/h.

6. Asphalt quality:

LB series is higher, is applied to high way and normal road normally.

DHB series: is applied to normal road normally.

The problem cases of baghouse dust collector of asphalt equipment in use

when The baghouse dust collector of asphalt mixing plant ran about 1000 hours, the smoking that the pipe of baghouse dust collector emitted is not only a high-speed stream, but also with a large number of ashes, and the operator found the bag is very serious blockage, A lot of holes on bag already, some sand holes on the pulse spray blowpipe. Dust bag change frequently. By the technical exchange and communication of technical personnel and Japanese experts, draw the conclusion: when baghouse dust collector leaving the factory, its dust collector box is out shape due to the defects of production process. Porous plate of deformation can't perpendicular to the air, which caused the tilt Angle. so the root reason of broken bag is that tilt Angle and some sand holes. Once the bag is damaged, the heat flow with the soot particle will directly through the dust bag - flue pipe - chimney - the atmosphere. If it is not a thorough overhaul, it not only can make the enterprise into the equipment maintenance cost and production costs greatly strengthen, reducing the production efficiency and quality, serious ecological environment pollution, causing a vicious cycle.

A common fault analysis of asphalt mixing plant - Filler Supply System

1. Material level is not normal

Diagnosis:

check the level meter output is normal or not;

check whether mineral powder played too hard, causing material level meter does not work properly.

Exclude:

output is not normal, the indicator to repair or replace the indicator;
if mineral powder played too tight, Filler Supply System should be cleaned, until normal.

2. Measuring nowadays powder is slow
Diagnosis:

check whether the butterfly valve switch is normal;
check whether the rotating feeder blade is stained with mineral powder;
Check whether the mineral powder is bulging in the tank.
Exclude:

Butterfly valve opening is not normal, to adjust its opening to the normal condition;
Rotary feeder with powder: ornamental butterfly valve, open the cover plate of screw machine ,open feeder, with a hammer knock the enclosure of feeder, until the feeder blade clean.
Mineral powder is bulging: first pressure breaker arch, if the result is bad, then with a hammer knock powder cans, and then if the result is bad, open of the powder tank entrance, broken arch by manual shovel powder.

A common fault analysis of asphalt mixing plant - the fault and solution of the dust collector

1. Dust leakage

Open the upper cover plate of baghouse dust collector, and check for cloth bag, take corresponding measures according to condition. Cleaning dust on the top of upper chamber, check if there is dust into the bag.

2. The problem of bag

a. the temperature of dust gas is too high

The temperature of dust gas must not exceed the maximum allowable temperature. The cloth bag can generally be under 200℃ high temperature, if the inlet temperature more than this value, the damper should be opened for the introduction of cold air cooling.

b. the humidity is too large

The bag is blocked if the climate is wet, so the wet cloth bag should be dried or replaces a new bag.

c. dust accumulation

If the dust accumulates at the bottom of the bag in the dust collector, the bag will accelerate wear. At this time, you shall check the running status of dust discharging device and check for leaks, and take corresponding measures.

d. bag wear

The inside of bag is dirty, because the dust is into the bag, which also caused the wear. In addition, if the dust is accumulated in the powder outlet, in order to prevent bag damage, the powder feeding device of the dust collector should be checked and the dust bag should be replaced.
