Steinhaus Airspring systems

Increased lifetime of screening machines
Within the steel construction of a screening machine usually various other aggregates as pumps, conveyor belts, log washers, etc. are in the perimeter. These units also emit vibrations set a steel construction in motion. Such external influences frequently lead to damage and premature failure of the screening machine. Due to the air suspension, the screening machine is optimally decoupled from the steel construction, disturbing external influences can no longer damage the screening machine.

5 – 10% energy saving
The reduction of lost energy through vibrations in the substructure results in an increased amplitude. If the increased amplitude is not used for a performance/production increase, one may scale back the centrifugal weights. This will result in a reduced current consumption by approx. 5-10% (up to 40% have been achieved max).

Improved durability for bearings
When the centrifugal weights are reduced to maintain the amplitude, another positive effect aside the reduced energy consumption is noticeable: The bearings of the screening machine are less loaded and achive a higher durability.

Calmed structural steelwork
The transmission of vibrations from screening machine to steelworks is reduced by approx. 80%. Vibrations in the perimeter are prevented, damages counteracted.

Raised Production /Improved Screening Result
As less energy is lost within the structure, the amplitude of the screening machine is increased. This produces a superior screening result and an increased production throughput, considering the approved acceleration by the fabricator. By this method, an increase in turnover by €44.000,-/month was verified.

Maintenance friendly
The lifetime of the airspring bellows is designed as a 7 years cycle. A change of a bellow can be easily done; after deflating the bellows the screening machine rests on the passive buffers. In opposite to steel springs the bellows can be changed without any lifting gear within a few minutes.

Workplace Safety
The danger of crushing, especially when the machinesshut down, is eliminated. Employer’s liability insurance often demands a surrounding for the springs to avoid accidents; this maintenance unfriendly demand is no longer required. The reduction of the vibration transmission is reducing the noise emission, improving the quality and safety of the workplace noticeable.

Constant Screening Result
In opposite to conventional steel springs or rubber springs, the airsprings never wear out from fatigue. This feature guarantees a constant screening result over the years, in addition to the capital saved.

Flexibility
The airspings can change the inclination of the screen by several angular degree. By this the screening machine can be adapted easily to changes in the bulk material.

Smart Control
Every set of airsprings is optionally equiped with an intelligent sensor system. The sensor system adjusts the machine fully automatically to changing parameters, either in the process or environmental. As an example, the airspring can adjust itself to a wavering ship, scaling the screen.Variations in the bulk can be automatically leveled by the inclination and pressure adjustment
