Bitumen mixing station

Ingredient System

• Variable-frequency control belt feeding, precise primary mixing.

• Material shortage alarm with de-caking device.Prevent empty or short-filled materials.Operates efficiently and smoothly.

• Set-styleHardened spur gear reducer, compact structure, high transmission efficiency, low failure rate, easy maintenance.

2. Dust Removal System

• German dust removal technology, a combination of inertial dust removal and pulse bag dust removal, dust emission less than 20mg/Nm³㎥Eco-friendly.

• Over-temperature Protection System, Dual Protection:When exhaust temperature is too high, the cold air valve automatically opens, and when the exhaust temperature is extremely high, the burner automatically shuts off.

3. Drying System

• The internal scraper blade of the drum is made from high-temperature and wear-resistant material, ensuring even distribution of the curtain and sufficient heat exchange, resulting in a long service life.

• Low-pressure atomization technology, mechanical-assisted atomizationAdjustment ratio up to 1:10.Adaptable to various fuels (diesel, heavy oil, low noise).

• Four-wheel friction drive, high transmission efficiency, and smooth operation.

4. Hot Aggregate Lifting System

• The bucket elevator features a double-row chain structure, offering low noise, smooth operation, and a long service life.

• The hopper is made of low-alloy high-strength structural steel, with wear-resistant strips added to the rim and treated with surfacing welding, ensuring robustness, stability, and a long service life.

5. Screening System

• Self-developed dual-axis exciter linear sieveExcitingThe vibrator motor combines with a twin horizontal (eccentric) shaft design, ensuring efficient operation. The screen mesh can be replaced quickly and easily, boasts a long service life, and requires no maintenance for the bearings.

• Design for excess material, triple protection: Sifting bin material level gauge, accurate monitoring; overflow pipeline, automatically releases material when full; excess/limit material channel, releases material when aggregate volume is too large or does not meet standards.

6. Measurement System

• The aggregate scale utilizes a tensile force sensor for cumulative measurement, featuring an automatic correction for splashing errors. Large-tonnage equipment employs dual aggregate scales for simultaneous measurement, with high measurement accuracy.±2.5%。

• The material scale uses a three-point tension sensor for cumulative measurement, with high accuracy.±2%。

• Bitumen weighbridge utilizes a three-point tension sensor, with secondary tracking measurement, achieving measurement accuracy of±2%。

7. Blender Tank

• Double-shaft mixer with high-strength, durable liners and bladesNickel-chromium alloyLong service life.

• Linkage flip gate for material discharge, quick opening and closing, no jamming.

• The finished goods warehouse is insulated, ensuring that the mixed material temperature drops ≤5℃ within 12 hours when the ambient temperature is between 15-25℃.

8. Control System

• German SIEMENS component PLC control cabinet, capable of automatic, semi-automatic, and manual control. Features include recipe input and storage, automatic correction of splatter errors, parameter adjustment, weighing calibration, dynamic tracking of oil stone ratio, automatic fault diagnosis, automatic alarms, and numerical report printing functions.

9. Installation & After-Sales Support

• Modular design for easy installation, maintenance, and quick relocation and transportation.
