LB3000 Asphalt Batching Plant is a new type of product developed and producted by our company in accordance with the needs of the market after absorbing the international advanced technology.It adopts a modular structure, fast transportation and convenient installation,compact structure,small occupation 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. 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 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.
Drying System Burner Control System
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.
