Mobile Concrete Plant SUMAB K-30 (30 m3/h) Sweden

The K-30 mobile concrete plant from the Swedish company Sumab is designed to produce high-quality concrete and concrete mixes at a capacity of 25-30 m³ per hour.

The mobile concrete plant is equipped with a user-friendly control cabin and an automatic plant control system. A modern Siemens computer system allows for the production of over 100 concrete formulas and grades.
It is possible to print out the kilograms and percentages of aggregates or cement for each finished batch during concrete mixing.

The mobile plant is mounted on a container frame, simplifying its relocation to a new site.

The basic plant configuration includes the following components:
1. Aggregate bins, 4 x 2.4 m³, with the option to extend the sides to 3.9 m³.
Panels made from specially pressed sheets, as well as a dismountable structure connected with bolts, ensure the bins are strong and wear-resistant. Discharge from one electropneumatically controlled gate on each hopper.

2. Aggregate weighing sensors. Located under the pan mixer. Dosing accuracy +/- 100 g. Siemens, Germany.

3. Aggregate conveyor from the hoppers to the mixer, including the electric motor (0-1500 kg). Equipped with four load cells with a high level of dosing accuracy.

4. Turbo mixer, capacity 1200/800 liters, lined with a 12 mm layer of Hardox 400 special steel.
5 quick-release paddles with fiberglass tips. Automatically opening concrete feed flap.
The special arrangement of the paddles in the mixer ensures coverage of all parts of the mixer during mixing, thereby ensuring high-quality concrete. The mixing paddles are angled to ensure rapid mixing of the mixture.

5. Cement batcher (0-300 kg) is equipped with a load cell for precise material weighing. A positive pressure hose is also installed to ensure accurate weighing. For more efficient unloading, the batcher is equipped with a vibrator and a galvanized service cover. Unloading into the mixer is accomplished via a pneumatically controlled rotary valve.

6. Galvanized water tank, 250 liters, with a built-in Danfoss pump and water supply metering device.

7. Compressed air system. Includes a compressor, pneumatic cylinders, pneumatic distributors, valves, air regulators, and compressed air supply hoses.

Maximum operating pressure: 10 bar.

8. Automated control system for the mobile concrete plant using a reliable Siemens S7-1200 programmable logic controller (PLC). The Siemens touchscreen panel allows for both automatic and manual operation. 9. The control cabin is a metal structure covered with sandwich panels.
10. Chemical additive pump with hose, automatically controlled by a PC.

Additional options:
1. Cement feed auger – 220 mm in diameter, 4.5 meters long.
Equipped with a 4.5 kW motor and gearbox and galvanized service covers.
• Capacity: 20 tons/hour
2. Conveyor for ready-mixed concrete from the mixer. Length: 12 m, width: 1000 mm
3. Cement silo, 30-100 tons (including level indicators, filter, ladder, railings, etc.).
The cement silo is collapsible
