Internationally renowned brands ,LB1000 ASPHALT MIXING PLANT long warranty

1) Hopper adjusts quantity of material by leather belt in control room.

2) Optimization designed Turndown rig of dryer which has a logical placement is either to improve efficiency or to avoid overheat of aggregate.

3) Hot material elevator use loop chain transmission, life is long, convenient maintenance, fine reliability.

4) Screening plant which uses middle four layers circular screen of single axle is high in efficiency, not easily blocked. Vibrancy bearing which has a cooler fan solves middle vibrancy bearing overheat problem. Screening plant reduces influence of noise on complete appliance by second shock absorption. Consequently decreasing influence on measuring system. The body of screen is airproofed in the cover to avoid pollution of dust, the cover is locked by spring device, easily disassembled.

5) Door of Storage bin is single one which is big gap, avoiding block and leakage of material.

6) Door of measuring bin is in compaction and reliable, also avoiding block and leakage of material, shaft sleeve of bin is made of graphite, dry lubrication, no needing lubricant at work.

7) Bitumen is nebulized and injected into the mixer coercively, mixed equality, time is reduced accordingly.

8) Shaft tip of mixer uses chevron seal, avoiding leakage of material.

9) Lining board in the mixer is high intension bearing material, after abration of blade, it’s direction can be changed, then using it newly.

10) Discharge door of mixer is form of push and pull, discharge hole is big, time of discharge is short. Dependability is good.

11) Dust collection system is a two grades system, the first is cyclone collection, after collection the filler goes into the hot material elevator and recycled. The second grade is wet collection, which is made up of two water pumps drenching the material. Efficiency of dust collection is improved very strongly. Bag collection is used in the second collection.

12) Complete appliance is controlled by industrial computer, easy to study and understand, precision is high, Dependability is good. Printer can print working form. Electrical components use oversea and domestic famous brand products. Dependability of hardware is guaranteed.

3. Working process

Asphalt mix material is made up of bitumen, aggregate, powder. The main work of Asphalt mixing plant is to mix the hot aggregate with bitumen, powder after they are measured by electronic scale, producing asphalt mix material which has certain graduation , certain temperature.

Working process as follows:

1) Loaders load various sandstone material into the cold aggregate hoppers, material is conveyed to the dry device after quantity of various material in each hopper is roughly adjusted. Material is conveyed to vibrating screen upstairs by elevator. By screened, various hot aggregates are screened into hot hopper apart according to graduation, by controlling small gate under hot hopper, material is put into measuring hopper, then the quantity can be confirmed. Measuring which is a control system is made up of electronic sensor, electronic scale, small gate, pneumatic cylinder, solenoid valve, controlling quantity of each material in hoppers by opening and closing gate. After measured, material is put into mix cylinder.

2) Hot bitumen is conveyed into mixing plant and injected into mix cylinder after measured by bitumen measuring jar.

3) Filler is elevated to filler storehouse of mixing plant and put into mix cylinder after measured.

Three materials are mixed and changed into final product.
