DHB Series and MDHB Series(mobile) are drum mixing asphalt plant; drying drum has functions of drying and mixing; their output is 20 ̴ 100tph,fitting for small and medium-sized road construction project.
◆ 1. Integrated structure , less land occupation;
◆ 2. Convenient for transportation and mobilization; MDHB series equipped with mobile chassis can be pulled by truck or vehicle.
◆ 3. Cold aggregate equips with weight sensor and variable frequency motor; aggregate feeding rate is remote controlled; precise aggregate feeding.
◆ 4. Drying drum have functions of drying, heating and mixing, low heat loss; optimized inner structure, fast heating and well mixing .
◆ 5. Low initial investment, highly cost-effective.
Model and Parameter
◆ Coal Burning system
The high efficient coal crusher integrated with speed adjustable coal powder supply,it provides the coal powder with size of less than 50 micron far the burner.the burner adopts oil supply device and wind supply device,and can provide sufficient heat energy for the mixing plant.
◆ Mixing Mainframe
Integrated drying,heating and mixing in the whole part the aggregate material will form an inadequate material flow in the drying section and go ahead promptly for preheating ,and then it will form a sufficient material flow and heat quickly in the heating section.in the mixing section, the asphalt and will be sprayed into the aggregate material, which makes the aggregate material and asphalt mixing equably.
◆ Cold Aggregate supply System
It can make aggregate material of four different sizes mixed well according to the construction requirement, for the oversized grain, it will be separated by the middle screen, and the qualified material will be conveyed into drying drum by tilted belt conveyer.
◆ Control System
The heat overload protect breaker is safe and reliable, the whole set control system is integrated on the operation platform, which is convenient and shotcut, the equipment has two operation modes: inter-lock operation and single-machine operation, which is convenient for equipment commissioning and production.
