As a blending silo with a capacity from 100 litres to 20.000 litres or as a large-capacity blending silo with a capacity of up to 100 m³. In a position suitable for inside or outside assembly. Low operating costs thanks to low required power, low-maintenance and wear.
Product-friendly homogenizing, drying, cooling and dyeing can for example be carried our in one working cycle.
The sizes and designs are variable and therefore can be adapted to nearly every field of application and site. The blending silo diameter and height are optional and have no influence on the blending quality.
Complete RUBERG Blending Silos in steel 1.0037, primed and lacquered, depending on the tasks to be fulfilled. Alternatively complete silo in stainless steel or in combined excecution, e. g. blending chamber housing in aluminium, blending screw in steel 1.0037, stainless steel or manganese high-carbon steel.
Feeding either in the lower part, whereby the components are fed by hand, or lateral feeding screw, e. g. with BIG-BAG feeding stations of bag feeding. With all necessary protecion devices and safety limit switches for covers and flaps, as well as with all necessary corresponding electrical safety locks.
Additional equipment such as cooling or ventilation connecting sleeve at the blending chamber. Filter connection piece or point filter on top of the housing cover to separate the dust particles from the outgoing air and simultaneous refeeding to the operating cycle. Blending silo standing on a weighing device (load cell) for weight recording or dosing. Heating, cooling or air drying plants for different operating cycles, complete with switch cabinet or SPC control.
Depending on its characteristics the product to be blended is fed either on top or at the side. It is also possible to feed it directly into the blending screw which is in the lower part. The blending screw consists of a sturdy central tube with welded anger-type helixes. The conical diameter and the progressive ascending slope are the decesive characteristics of the blending tools. They are chosen according to the silo diameter. Thanks to the special geometry of the open, slow turning blending anger the product can slowly flow from all horizontal levels of the silo towards the centre, where it is fed upwards with a slowly increasing feeding speed.
