160 Ton QLB-2000 asphalt mixing plant with weighing accuracy reaches 0.1%

Working condition of asphalt plant:

1, Water content of aggregate ≤5%
2, Environmental temperature +0+50
3, Altitude ≤1000m
4, Proportion of average density is 1650kg/m3
5, Heating value of fuel≥10000kacl/kg
6, Residual water content of the mixture≤0.3%
7, Max diameter of aggregate is 40mm
8, 3mm aggregate screening efficiency≤35%
9, The productivity includes 5~10% powder and asphalt
10, The aggregate should be in normal shape and should not have a lot of holes or water suction.
The productivity ranges from ±10% as the effect of surrounding environment and material parameter
Max dust content of the aggregate is 250mg/Nm3

When adopting the SMA modified asphalt additives, because of extending of mixing time and increasing temperature of the finished asphalt mixture, it would influence the productivity to reduce by 10%.

Features:

1, mixing arm and blade are made of high strength high chrome alloy steel for longer service life.

2, Quantity of aggregate silo reaches up to seven for various sizes and specifications

3, Cold aggregate bin adopts two-hopper-integral type, inlet of each bin has separated screen for rough & waste materials, operation platform and material shortage alarm device, with two wall vibrators.

4, Hot aggregate elevator adopts double row plate link chain to prolong service life

5, Straight type screen driven by imported vibration motor decreases failure rate

6, Adjustable flame profile of burner realizes best match with various drying drums
