Manufacturer: SKAKO
Year of Construction: 1993

1) Feeding and distribution plant for aggregates consisting of:

1 x Feeding bunker
- Dimensions: 3,0 m x 3,6 m
- Bunker volumen: approx. 25 m3
- Robust safety grating, truck passable max. 12 t axial pressure
- 2 x Vibrating feeder
- Capacity in total: approx. 60 kg/s
- Control system of the feeding and distribution plant
- Belt conveyor with centre distance: 96 m, bandwidth: 800 mm, drive: 31 kW, gradient: 15°, capacity: 210 m3/h, Belt conveyor speed: 1,5 m/s, belt conveyor runway
- Movable distribution belt conveyor, reversible, for the feeding of 12 aggregates compartments in 4 tower silos, maintenance bridge
- 20 x Level warning device

2) Silo plant for aggregates

4 x Sheet steel-round silo
- Manufacturer/type: SKAKO HS 750
- Designed for aggregate grain sizes between 0-64 mm at bulk weight of 1,8 t/m3
- Silo-diameter: 8000 mm
- Total height: 21 m
- Geometrical content of each silo: 750 m3
- Number of silo aggregates compartments (each silo): 3 compartments (120°)
- Total content 12 x 250 m3 = 3000 m3
- Dewatering of the silo compartments

The silo interior space (all parts screwable and demountable in transportable segments) are splited by vertical standing partition walls. There is an entrance to the upper section of the silo plant through the runway of the belt conveyor. At the top area of the silo plant is an maintenance platform which were installed at both sides of the distribution belt conveyor. The silo housing consists of PVC coated sheet steel and reaches to the ground.
The upper part and the connection bridges are housed.

4 x Supporting structure for the für Sheet steel-round silo

3) Dosing system for aggregates

12 x Electromagnetic vibrating feeder for the outlet of the individual aggregates,
control system allowes coarse and fine dosing, adjustable for each grain size
3 x Dosing belt conveyor for Liapor 0/4 and 0/8
2 x Weighing belt conveyor, centre distance: 28 m and 27 m, bandwidth 800 mm

The measured value transmission happens over torque load cells which are hanging on the under edge of the silos.

2 x Weighing container for aggregates, weighing range 750 - 7500 kg and 480 - 4800 kg
