1. A bellows system for a screening machine for screening, preparing, or refining gravel, sand, or other bulk material, the bellows system comprising:
a bellows interior space adapted to be filled with compressed gas, a gas pressure source connected to the bellows interior space by an gas line, wherein an inlet valve is arranged in the gas line, wherein when the inlet valve is open pressurized gas flows into the bellows interior space, wherein when the inlet valve is closed pressurized gas does not enter the interior space, a sensor, wherein the sensor measures gas pressure inside the bellows interior space, an exhaust valve, wherein the exhaust valve is connected to the bellows interior space, wherein the when the exhaust valve is open pressurized gas flows out of the bellows interior space, wherein when the exhaust valve is closed pressurized gas does not flow out of the bellows interior space, a control unit and a control line, wherein the control line connects the control unit to the inlet valve, wherein the control unit is in communication with the sensor, wherein the control unit receives gas pressure information from the sensor, wherein the control unit automatically or manually adjusts the position of the inlet valve and the position of the exhaust valve based on the gas pressure measurement inside the bellows interior space, and wherein the bellows system is configured to support the screening machine. |
