Features

LB1000 asphalt batching plant is a stationary hot mix asphalt plant developed and manufactured by Handa in accordance with the needs of the market after absorbing the international advanced technology. The mixing plant adopts a modular structure, fast transportation and convenient installation, compact structure, small cover area and high cost performance. The total installed power of the device is low, saving energy, can create considerable economic benefits for the user. The plant features accurate measurement, simple operation and stable performance which fully meets the requirements of highway construction and maintenance. 
1. Skirt type feeding belt to ensure more stable and reliable feeding.
2. Plate chain type hot aggregate and powder elevator to extend its service life.
3. The world's most advanced pulse bag dust collector reduces emission to be below 20mg/Nm3, which meets the international environmental standard.
4. Optimized design, while using high energy conversion rate hardened reducer, energy efficient.
5. Plants pass through the EU, CE certification and GOST(Russian), which are in full compliance with U.S. and European markets for quality, energy conservation, environmental protection and safety requirements.

 

Main Structure

1. 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.

2. Drying System   

- 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.

3. Vibrating screen

- 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.

4. Weighing system

- Adopt famous brand METTLER TELEDO weighing sensor, make sure accurate weighing, in order to make sure the asphalt mixture quality.

5. Mixing system

- 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.

6. 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.
