MOBILE AND FIXED QUARRY PLANTS-CRUSHERS
VERTICAL AXIS- ROTORS- HAMMERS- CONES- JAW HOLDERS- ROLLER MILL
Plant design & machinery supply focusing
in productivity and time lasting
Smart time management, through software developed based on strict specifications, further increases the productivity of the unit in relation to its theoretical performance.
Crushing machinery (stationary or full mobile) & granular classification units (screens) for aggregates taken directly from quarries (mining boulders, crushed stone, gravel, sand) through mining activities.
Procedure:
- Transportation & line feed via special conveyor belts
- Collection in feeding hoopers
- Prescreening through heavy duty rejection grid
- Natural shape classificationvia vibratingor rotating screens
- Crushing procedures (Jaw, Impact, Cone crushers)
- Crushed material classification in vibrating screens
- Further size reduction for smaller granules (vertical shaft crushers)
- Stockpiling in selected areas (or in containers) per granulometry via conveyor belts.
STEFAS ERGONoffers also mobile crushing and screening units: the best solution in bringing the machinery near the project area, reducing that way the functional costs. They are powered from the local power network or through power generator. STEFAS ERGON offers also full self-standing units (autonomous – in trailersor tracked) carrying Dieselengines.
The detailed design of the units with absolute dedication to the quality final result, characterizes STEFAS ERGON. We record the customer’s requirements, we study and design, ensuring the economy in the consumption of energy resources, the minimum environmental burden and we offer reliable quality & certified equipment of great durability over time.

ROTATING SCREENS-WHEELS-VIBRATING SCREENS AND VIBRATING FEEDERS
Proper management of raw materials is the factor of excellent quality in the final result
Complete plants for the management, cleaning & grading of aggregates (sand, gravel, crushed stone) taken in their natural shape direct from the environment.
Procedure:
- Transportation & line feed via special conveyor belts
- Material grading using vibrating/rotary rinsing screens
- Cleaning via pressured water from nozzles or in overflow tanks
- Stockpiling in selected areas (or in containers) per granulometry via conveyor belts.
STEFAS ERGON undertakes on behalf of the customer the detailed recording of production demands as well as the area availability for the installation. Then studies, designs & installs the plant, combining the compatibility & the versatility of the offered machinery with the result.
Great importance is always given to:
- Compact & ergonomic design
- Functional simplicity & minimum infrastructure costs
- Low environmental nuisance along with low energy usage
- Construction quality with long lasting certified materials
- Low operational & maintenance costs
