SLHB-8 type double drum mobile intermittent asphalt mixture mixing machine
Our factory's SLHB-8 type double-drum mobile intermittent asphalt mixture mixing machine adopts a trailer structure where the drying drum and the mixing drum are integrated as a whole. The overall machine occupies a small area, and the installation period for moving and positioning is short. The fuel application range is wide. It features simple operation, convenient maintenance, stable and reliable performance, excellent quality of finished materials, high degree of automation and standardization, etc. It can meet the maintenance and construction operations of various high-grade asphalt pavement under various geographical conditions. It is especially suitable for medium and small-sized road maintenance teams as a supporting equipment for maintenance and construction operations.
This model is equipped with two types of engines for users to choose from: the fuel-type SLHB(Y)-8 and the dual-fuel type SLHB(M)-8.
The specific performance features of the SLHB-8 mixer are as follows:
1.The main unit can be moved by towing as a whole. The relocation, disassembly and reinstallation process is short, the operation is simple and the maintenance is convenient.
2. Adopting hydraulic support feet, the installation and adjustment are effortless and time-saving, and the stability is reliable.
3. The dust removal system adopts a double-tube type cyclone dust collector, which has a good dust removal effect.
4. The drying drum is made of 16Mn steel with a thickness of 16mm, and the main beam is constructed by welding together 18# heavy-duty channel steel into an integral frame structure.
5. The hot asphalt metering and conveying device adopts the method of conveying through asphalt pumps and metering by liquid level relays, ensuring accurate asphalt-to-gravel ratio.
6. The control system is highly integrated and automated. The main controller and display adopt the programmable controller and display terminal of Omron PLC from Japan, enabling automatic and manual centralized control of the system.
7. For the key components of the electrical control cabinet, internationally renowned brand components are adopted, including:
Buttons, contactors, motor starters, molded-case switches, terminal blocks: Siemens;
PLC programmable controller, programmable display, time relay: Siemens.
8. The combustion furnace assembly can be used for both coal and fuel oil combustion. It adopts an electronic automatic ignition device. The applicable fuel range includes pulverized coal or diesel, heavy oil, residual oil, etc., which are combustible fuels. If a coal grinding and powder supply device is selected, it can also realize the entire working process from crushing small coal lumps, grinding, blowing to automatic ignition, complete combustion, and automatic slag discharge. Moreover, the supply of coal can be directly adjusted to regulate the flame size, and the output temperature of the finished product can be conveniently adjusted to meet the requirements of different construction conditions. The new combustion furnace assembly has high technical content, low fuel consumption, and remarkable economic effects. It is particularly suitable for the usage requirements of users in various geographical conditions. All specifications and models of the combustion furnaces in this series use high-performance indicators of formed refractory bricks to build the furnace chamber. Ordinary workers can easily complete the installation and replacement of furnace bricks according to the random installation diagram, greatly facilitating on-site production.
9. This equipment effectively overcomes the inherent defects of domestic straight-tube continuous mixing equipment, such as:
⑴ Asphalt is prone to aging.
(2) The continuous measurement accuracy of the aggregates and asphalt is difficult to guarantee.
