Our powerful solution for low emissions when delivering dust-intensive bulk materials.
RUBERG Gutter dust extraction plants are available as a vibrating hose extraction wall, a jet hose extraction wall or as an extraction wall with a decentralised filtering device.
RUBERG Lamella dumping gutter
Input gutters with a high use frequency can be fitted or also retroactively fitted with an additional lamella system. This sealing system closes the grid device at the top so that no dust-air mixture can escape. Using RUBERG lamella dumping gutters means that fewer modules are required for the suction power of the gutter dust extraction plant which results in lower investment and energy costs.
Threshold limit values are significantly below average for all design variants.
Extracted air can, for example, be released outdoors via a silencer and a deflector hood. An air curtain as a circulating air airlock in the approach area is a further possibility for using the exhaust air.
RUBERG Vibrating hose extraction wall
Here, we work with a modular design, i. e. a cabinet module (2.000 mm W x 2.100 mm H x 500 mm D) consists of the suction cascade, the filter hose series, the vibrating beam with the unbalance motor, inspection hatches and the connector. During the pouring-in process when a product is delivered, the dust cloud is guited via the cascade into the interior of the filter hose series. Dust and coarse particles remaind attached to the walls of the hose series. The pure air is then fed outside through the connector via fans. After unloading is finished, the extraction is switched off. The vibrating mechanism starts up and the product falls from the filter hose walls back into the loading gutter.
RUBERG Jet hose extraction wall
We also work with a modular design here, i. e. a cabinet module (2.000 mm W x 2.100 mm H x 500 mm D) consists of the suction cascade, the filter hose series, magnetic valves, compressed air reservoirs, the pressure difference measurement device and the filter controller. During the pouring-in process when a product is delivered, the dust cloud is guited to the filter hose series. Dust and large particles remain attached to the outer walls of the hose series. Compressed air pulses in the counterflow, triggered by the pressure difference device and the filter controller, clean the filter hoses during the entire unloading process. The dust is constantly quited downwards into the delivery gutter.
RUBERG Extraction wall with a decentralised filtering device
The input gutter contains just one sheet suction cascade with an air collector pipe above it which is fed to a decentrally positioned RUBERG flexible hose nozzle filter. This is a flexible hose filter with a radial fan directly downstream, a silencer and a discharge air line with a deflector hood at the end. The dust is separated out in the filter and returned for further use via a RUBERG discharge valve.
