Brief Introduction to LB Series of Modular Asphalt Mixing Plants atures: 1. The original modular design of the mixing plant makes transport and installation work quick and convenient. It canseparate extra-large flotsam from usable stuff. 2. The loop belt feeder for the measuring hopper has a frequency-conversion speed regulator which can provide high and low speed. Its originalstructure facilitates belt change and makes material feeding more fluent, which reduces power consumption. Besides, there is a warning light which will remind the user when the machine uses up rawmaterial. 3. The high-efficiency and heat-preservation drying drum and the special vanes make heat exchange more sufficient. Moreover, the high-efficiency and energy-saving imported burner can useboth heavy oil and diesel, which reduces energy consumption. 4. The vibrating screen adopts the linear and completely-closed design with the vibrator placed outside. The sieving efficiency is high,the maintenance and changing of screen is easy, and the imported bearings are more reliable. 5. The hot aggregate bin is equipped with a continuous level indicator which enables the operator to knowthe level of material at a glance. The measurement of aggregate is conducted twice through large and small doors, which greatly improves the measuring precision. The unique structure of the materialemptying door reduces the chance of blockage and will work more reliably. 6. The main mixing machine designed with European technology has double reducers with a high-speed synchronization tely-weighed asphalt can be directly pumped into the agitating kettle and powder material can be conveyed into the agitating kettle through the helix, which makes agitating more even andspeedy. Besides, it has an opening to add wood fiber and an inlet to add used material to be recycled. 7. The dust-removing system adopts imported NOMEX bags which limit the density of dustdischarged into the air within 50mg/m3, which is completely up to the national standard of environmental protection. The dust blown down will be collected into the collection tank through the dustlifter for reuse to avoid secondary pollution. 8. The control system adopts the SIEMENS integrated solution which plays a leading role in the industrial automation field. It also uses the PROFIBUSfield bus to form a large and medium-sized distributed automatic system. In operation, the equipment adopts the technology of double hot standby on the industrial computer, dynamic display andbuttonless design. All operations are done through the mouse. It has the real-time fault monitoring and control system with functions like parameter setting, data management and fault diagnosis. Itmeasures precisely and can be controlled automatically, semi-automatically and manually, showing a stable and reliable performance. chnical Parameters [table][tr][td] Type[/td][td]LB500[/td][td] LB750[/td][td] LB1000[/td][td] LB1500[/td][/tr][tr][td] Rated production[/td][td] 40t/h[/td][td] 60t/h[/td][td] 80t/h[/td][td] 120t/h[/td][/tr][tr][td] Cold Aggregate Bin[/td][td]4X6m3[/td][td] 4X6m3[/td][td] 4X9m3[/td][td] 4X9m3[/td][/tr][tr][td] Dry Cylinder[/td][td] 1.1mX4.2m[/td][td] 1.3mX5m[/td][td] 1.5mX6m[/td][td] 1.8mX7m[/td][/tr][tr][td] Bag-typeDust-collector[/td][td] CNM156[/td][td] CNM240[/td][td] CNM357[/td][td] CNM476[/td][/tr][tr][td] Emission Standard[/td][td] 50mg/nm3[/td][td] 50mg/nm3[/td][td] 50mg/nm3[/td][td]50mg/nm3[/td][/tr][tr][td] Vibrating Screen[/td][td] 4 layers[/td][td] 4 layers[/td][td] 4 layers[/td][td] 4 layers[/td][/tr][tr][td] Hot Aggregate Bin[/td][td] 12t[/td][td] 12t[/td][td] 26t[/td][td]26t[/td][/tr][tr][td] Mixing Kettle Capacity[/td][td] 500kg[/td][td] 750kg[/td][td] 1000kg[/td][td] 1500kg[/td][/tr][tr][td] Mixing Cycle[/td][td] 45s[/td][td] 45s[/td][td] 45s[/td][td]45s[/td][/tr][tr][td] Mineral Powder Tank Volume[/td][td] 30t[/td][td] 30t[/td][td] 26+36t[/td][td] 26+36t[/td][/tr][tr][td] Asphalt Tank Volume[/td][td] 30000L[/td][td] 30000L[/td][td]50000L[/td][td] 50000L[/td][/tr][tr][td] Heat Conduction Oil Stove[/td][td] 200,000 kcol/h[/td][td] 200,000 kcol/h[/td][td] 300,000 kcol/h[/td][td] 300,000 kcol/h[/td][/tr][tr][td] End-productContainer Volume[/td][td] 50t[/td][td] 50t[/td][td] 90t[/td][td] 90t[/td][/tr][tr][td] Control System[/td][td] Manual /Semi-auto / Automatic[/td][/tr][tr][td] Weighing Accuracy[/td][td]Aggregate[/td][td] ±4%[/td][td] ±4%[/td][td] ±4%[/td][td] ±4%[/td][/tr][tr][td] Powder Material[/td][td] ±3%[/td][td] ±3%[/td][td] ±3%[/td][td] ±3%[/td][/tr][tr][td] Asphalt[/td][td]±2%[/td][td] ±2%[/td][td] ±2%[/td][td] ±2%[/td][/tr][tr][td] General Installed Power[/td][td] 190kw[/td][td] 210kw[/td][td] 230kw[/td][td] 320kw[/td][/tr][/table] [table][tr][td] Type[/td][td]LB2000[/td][td] LB2500[/td][td] LB3000[/td][td] LB4000[/td][/tr][tr][td] Rated production[/td][td] 160 t/h[/td][td] 200 t/h[/td][td] 240 t/h[/td][td] 320 t/h[/td][/tr][tr][td] Cold AggregateBin[/td][td] 5X11m3[/td][td] 5X11m3[/td][td] 5X11m3[/td][td] 5X11m3[/td][/tr][tr][td] Dry Cylinder[/td][td] 2.2mX8m[/td][td] 2.35mX9m[/td][td] 2.5mX10m[/td][td] 2.8mX11m[/td][/tr][tr][td] Bag-typeDust-collector[/td][td] CNM654[/td][td] CNM832[/td][td] CNM1012[/td][td] CNM1308[/td][/tr][tr][td] Emission Standard[/td][td] 50mg/nm3[/td][td] 50mg/nm3[/td][td] 50mg/nm3[/td][td]50mg/nm3[/td][/tr][tr][td] Vibrating Screen[/td][td] 5 layers[/td][td] 5 layers[/td][td] 5 layers[/td][td] 5 layers[/td][/tr][tr][td] Hot Aggregate Bin[/td][td] 5/40t[/td][td] 40t[/td][td]80t[/td][td] 100t[/td][/tr][tr][td] Mixing Kettle Capacity[/td][td] 2000kg[/td][td] 2500kg[/td][td] 3000kg[/td][td] 4000kg[/td][/tr][tr][td] Mixing Cycle[/td][td] 45s[/td][td] 45s[/td][td]45s[/td][td] 45s[/td][/tr][tr][td] Mineral Powder Tank Volume[/td][td] 30+43t[/td][td] 30+43t[/td][td] 50+35t[/td][td] 60+35t[/td][/tr][tr][td] Asphalt Tank Volume[/td][td] 50000L[/td][td]50000L[/td][td] 50000L[/td][td] 50000L[/td][/tr][tr][td] Heat Conduction Oil Stove[/td][td] 500,000 kcol/h[/td][td] 500,000 kcol/h[/td][td] 800,000 kcol/h[/td][td] 1,000,000 kcol/h[/td][/tr][tr][td]End-product Container Volume[/td][td] 110t[/td][td] 110t[/td][td] 200t[/td][td] 200t[/td][/tr][tr][td] Control System[/td][td] Manual /Semi-auto / Automatic[/td][/tr][tr][td] WeighingAccuracy[/td][td] Aggregate[/td][td] ±4%[/td][td] ±4%[/td][td] ±4%[/td][td] ±4%[/td][/tr][tr][td] Powder Material[/td][td] ±3%[/td][td] ±3%[/td][td] ±3%[/td][td] ±3%[/td][/tr][tr][td]Asphalt[/td][td] ±2%[/td][td] ±2%[/td][td] ±2%[/td][td] ±2%[/td][/tr][tr][td] General Installed Power[/td][td] 400kw[/td][td] 530kw[/td][td] 720kw[/td][td] 820kw[/td][/tr][/table]
