Introduction In order to satisfy the need of high-grade highway construction, has cooperated with domestic Relevant scientific researching institutions, absorbing the advantages of foreign bituminous mixed-materials mixing equipments and developed Type No: QLB-1000, Type No: QLB-2000, and Type No: QLB-1500 bituminous mixed-materials mixing equipments, which are at the leading level at home, A complete set is formed by a mainframe mixing machine, drying system, advancing system for providing and delivering materials, stone powder advancing system, sieving and measuring system, heat conduction and oil heating bitumen supply system, pulse bag type dust removal system, as well as a finished materials storing system, The complete set of equipments is adopted by the computer automatic controlling system, and is protected by high quality armor. BAGHOUSE DUST CATCHING SYSTEM The bughouse dust catching system has compact construction, easy to remove dust, This system use named material bag, can resist high temperature up to 250 degree. The air vent concentration less than 100 mg/Nm3, this system can meet the environmental requirement of China. The control system inquired with high temperature and low temperature alarm device. When high temperature alarm occurs, heating system will auto. Cut off. The system will automatic control the blow clean cycle time. Particular design of bughouse makes the dust catching system has high reliability, enormous filter area, high efficiency of dust catching. Filter bag no eddy to dew or burn out. The dust cached on bag will return to the dust recycle bin and can reuse this dust. FINISHED PRODUCT STORAGE BIN SYSTEM The large capacity of finished product storage bin system uses the heat conduction oil to heat and circulate the system to keep the system of rated temperature; This system decorated by chromatic steel plates has a very nice appearance. The special design foldaway rails, special brake system, lorry speed automatic control system, ensured the lorry move stable and stop/start at a accurate position. BITUMEN FEEDING SYSTEM Heat conduction oil system use high quality imported burner, manometer, thermostat, The burner had the functions of automatic ignition, automatic survey working state, The system can full automatic working; You need only set the scope of working temperature and pressure. Bitumen tank equipped with special coiled tubes for heat exchange, there is a check valve on the coiled tube, it will control the heat conduction oil flow rate according to the bitumen set up temperature. Parameters Type No QLB-1000 QLB-1500 QLB-2000 Specified productivity ratio (T/h) 60~80 90~120 120~160 The capacity of the mixing jar(Kg) 1000 1500 2000 The power absorption (Kw) 245 333 450 The fuel consuming rate (Kg/T) 6~7
