Cold Aggregate Feeding System
- The belt feeder use frequency conversion speed control, speed adjust rang is wide, high working efficiency.
- Every hopper discharge gate have material shortage alarming device, if material shortage or material arching, it will alarm automatically.
- On the sand bin, there is vibrator, so it can guarantee normal working.
- There is isolation screen on top of cold bin, so can avoid large material input.
- The conveyor belt use circular belt without joint, steady running and long performance life.
- At the input port of feeding belt conveyor, there is one simple screen can avoid big material input which can enhance hot efficiency and make sure the drying drum, hot aggregate elevator and vibration screen work reliability.
- The blade geometry of the dryer has been optimized to deliver an exceptionally efficient drying and heating process with reduced energy consumption,improve heating efficiency 30% than conventional design; Because of High heating efficiency, drum surface temperature is relatively low, so the cooling time after operation is considerably shorted.
- Fully insulated and clad aggregate dryer. Drive by electric motors and gear unit through polymer friction drive support rollers.
- Adopt famous brand HONEYWELL temperature intelligent control system.
- Adopt high combustion efficiency Italian brand burner, make sure low exhaust gas emission (like CO2,low No1 & No2, So2).
- Diesel, heavy oil, gas, coal or multi-fuel burners.
- About asphalt mixing plant, specially designed heavy(light) oil burner, has high effect, stable air volume, save oil and electricity.
- Coal burner and oil burner are available, coal burner with low product cost, is only 1/3 of oil burner, is the ideal choice for customer. The oil burner can use heavy and light oil, has no need to change any component, the consumption is less than 6.5kg/t(finished product) under standard condition.
- Adopt international standard components, with low maintenance cost.
- Improved vibration and amplitude to optimize impact on the available screen.
- Wear-resistant charging system with uniform distribution of the particle mix.
- Wide open doors for easy access and screen meshes are simple to replace, so the down time is reduced.
- The best combination of vibrating direction & screen box dip angle, ensure ratio and screening efficiency.
- Adopt famous brand METTLER TELEDO weighing sensor, make sure accurate weighing, in order to make sure the asphalt mixture quality.
- Mixer are designed by 3D mixing design, with long arms, shortened shaft diameter and a bi-directional mixing blades array.
- The discharging process has been completely redesigned, the discharge time is minimal.
- The distance between blades and bottom of the mixer is also restrained to the optimal minimum.
- Bitumen is sprayed from multi-points evenly over aggregate by one pressurized bitumen pump to achieve full coverage and high mixing efficiency.
Dust Collecting System
- Gravity primary dust collector collecting and recycling bigger fine, saving consumption.
- Bag house secondary dust filter control emission be lower than 20mg/Nm3, eco-friendly.
- Adopt USA Dopont NOMEX filter bags, high temperature resistance and long service life, and the filter bags ban be replaced easily and quickly with no need for special tools.
- Intelligent temperature and control system, when the dust air temperature is higher than set data, cold air valve will be opened automatically for cooling, avoid the filter bags are damaged by high temperature.
- Adopt high voltage pulse cleaning technology, contributing to a lower bag wearing, longer lifespan and better dust removal performance.
Bitumen supply system
-Bitumen tank is sturdy and durable. Different sizes and capacity of bitumen tank can be provided according to the customers requirements. The bitumen tank is covered by rock wool insulation layer and galvanized sheet, which maximally decrease the heat loss.
-Bitumen tank is heated by the heat conduction oil, which make sure the temperature of the bitumen.
- Adopt Germany SIEMENS electrical element, working stably even in harsh working environment.
- Adopt Japan ORMON PLC and touch screen, have high data processing capacity, with automatic data sheet control, various operation data can be saved real-times.
- All system power switches can be controlled via control panel,easy operation and control.
- Multi-language compatibility, display language can be selected according to the customer’s preference.
- Control cabinet adopt IP55 safety protection class which can match highest industrial standard in whole global.
- Containerized control room, with heat insulation and sound insulation layer.
- Global remote automatic detection function.
