LB asphalt mixing plant produced independently by our company offers a wide range of specifications from LB1000 to LB 4000.
LB asphalt mixing plant produced independently by our company offers a wide range of specifications from LB1000 to LB 4000, and can be equipped with different dust-cleaning apparatus and different structures of end product bins according to customer's requirements. LB asphalt mixing plant has the characteristics such as performance stablehigh reliabilityhigh rate of qualified productlow breakdown rate, etc. which can meet requirements of all kinds of high-quality asphalt mixing, it has received unanimous appraisal from our old customers.
Main Equipment Features:
1. Primary material proportioning system adopts step-less frequency control of motor speed, the quantity of feeding materials is stable and the adjustment is convenient.
2. The burner system adopts high quality foreign burner, the quality requirements for fuel is extensive, the adjusted ratio is large, and the heat efficiency is high. Friction drive is applied in drying drum. Heated parts and rubbed parts in drum are made of special steel, which improves heat and friction resistance and keeps a longer life.
3. Screening system adopts high-performance and high-reliability LZSF asphalt screen.Vibrator is outfitted outside with good heat shrinkable and bearing life can be improved greatly. The vibrating screen adopts 4-6 classifications screening according to mixing plants requirements with the features of large handling capacity, long service life, high screening efficiency.
4. We adopt advanced measuring system the function of automatically correction of measurement error. It has the function of automatically correction of measurement error. The system has the features of high measurement accuracy and precise propertioning ratio.
5. The control system adopts computer control to achieve real-time monitoringfault diagnosising and automatic alarm.It has both automatic and manual operation, avoiding being forced to stop production as a result of automata failure and then impacting the progress of construction works.
6. The valves of insulation asphalt and conducting oil in pipe system are a new model cylinder stopcock developed and made by our company. No filling is between faucet and out shell for seal. There is no leakage or pollution. And it is free to start, easy for automatic control and remote control. Three-way valve and Two-way valve simplify pipeline design. In the system the three-way valve adopted makes the asphalt and hot oil pipeline optimizedsuccinct, and is beneficial for the reduction of temperature loss and reduction of cost.
7. The dust-cleaning system adopts two-stage dust-cleaning way of cyclone and bag. It applies pulse valve to blow dust, especially when there is high thickness of dust to purify, effect is remarkable. It can decrease air pollution effectively and comply with the environment protection requirements.
8. The design and structure of mixer is reasonably, small filling rate, short recycle period, strong mixing capability. The mixing is evenly and completely. Mixer plate and vane are made of high intensity of wear resistant material. Service life can be up to 50000 times.
9. The finished product bin has felt proof and isolation proof technique, emptying door assisting heating with electricity. Its capacity is 100 ton(single bin), 200 ton(double bin). It has two forms of construction: scraper type and bucket elevator type.
Scraping conveyor can transfer finished product continuously and is air tight and good in temperature preservation without influence from outside.
Bucket elevator adopts frequency control of speed which effectively reduces electric current and machinery impact produced by hoisting and falling of bucket loader. Period of stroke is less than that of mixing to guarantee continuity and efficiency of production.
