Features

LB1500 asphalt batching plant is a stationary asphalt mixing plant developed and manufactured by Handa in accordance with the needs of the market after absorbing the international advanced technology. The asphalt 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. It has the advantages of accurate measurement, simple operation and stable performance, and 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 hoist, to improve the life of the hoist.
3. Using the world's most advanced technology pulse bag dust collector, soot emissions below 20mg/Nm3, meet the highest international environmental standards.
4. Optimized design,while using high-energy conversion rate hardened reducer, energy efficient.
5. Plants pass through the EU, CE and GOST(Russian), the products in full compliance with U.S. and European markets for quality, energy conservation, environmental protection and safety requirements.

1. The asphalt mixer uses the high strength wear-resistant materials which increases the service life;
2. The installation of first-lever cyclone dust filter and second-lever water filter systems, together with negative-pressure dustproof design of the plant body, substantially save investment costs for customers due to their superior economy as well as practicality;
3. The linear-mode vibrating sieve is driven by imported vibration motor which helps improve the screening efficiency and reduce the plant failure frequency.
4. The aggregate elevator is lifted by plate chain, which not only raises the service life of the hoisting machine but improves the running stability;
5. Optimized chain board type drying drum makes the drying system more effective and stable;
6. Overall modular design makes it fast and convenient to transport and install;
7. Full automatic computer/man control system with a self-diagnosis and feedback program guarantees an easy and safe operation.

Drying System

Drying system is the key part of the whole equipment, its drying ability affects the mixing capacity directly, the aggregate temperature can directly affect the finished product temperature, the drying efficiency influence the fuel consumption greatly. Therefore the design of structure rationality is very important.

Drying system includes drying cylinder, main burner and fuel feeding sytem. There are four gear reducers connected to four friction wheels by cross head univesal shaft to drive the drier, with the advantages of installation deviation compensation, high driving efficiency, stable dricing and so on. The external insulating  layer and the specially designed blades ensure that maximum heat is transfered to the aggregate. The thermal efficiency is high and the exhaust temperature at the end of the cylinder is below 120 degree. The world advanced burner is adopted. The usable fuel includes diesel, heavy oil, residual oil, gas, coal and so on. Another alternative burner developed by ourselves has the same performance with 8:1 adjusting rate, economical efficiency and adaptability with the former. All components of the advanced infared temperature measuring and controlling syystem are imported from famous overseascompanies to ensure the temperature control accuracy and reliability.

Dust Collecting System

German techniques are adopted to combine the two-level dust collectors in order to save the floor space specially designed first-stage inertial dust separator has the simpler structure and the higher efficiency. The bag dust collector is designed with the flat bags. The structure is compact and the dust can be easily cleaned out. The filter bags are made of the fire-resistant material, which can satisfy the requirement of environmental protection standard. 

The high-low temperature alarm device and the automatic flame out device for too high temperature are designed in the control system. The unique designed blow back system and other special design ensure the dust removal system to work reliable.


                                                                                                                                                                                                     

Burning system

- 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.
