The use of weighing load cells in combination with the Sac Master can ensure that large volumes of material can be discharged direct from an IBC with accuracies of +/- 0.5 percent. Volumetric and gravimetric feeding is also possible if a Schenck Process MechaTron feeder is integrated. The complete system can also be controlled and monitored using the Disocont and Disomat technology.
The SacMaster has a modular design that allows it to be used anywhere for a variety of process requirements. The SacMaster empties even the most difficult bulk solids from bulk bags of all types and sizes: from free-flowing plastic granules to poorly flowing titanium dioxide or calcium carbonate.
It is fitted with a PosiFlow discharge aid that has adaptive paddle movement to ensure optimal product discharge. The functions and features of the PosiFlow can be varied for use with different products and set to fit any size of bulk bag. The continuously adjustable telescoping rack also allows the height of both the bulk bags and the feeders to be adjusted.
To provide greater flexibility partially emptied bulk bags can remain in the discharge station until further processing is required. An optional iris valve closes the receptacle until processing has continued and the special docking station prevents dust from escaping into surrounding areas.
The modular design of Schenck Process SacMaster enables it to be used with a large number of materials and process areas and is easily incorporated into factory layouts for new build or refurbishment projects.
For liquid bulks, Schenck Process has launched a dynamic rail weighbridge. The weighing of liquids transported in tank wagons is a particularly challenging task for measuring and weighing technology, the company said. These substances are in almost constant motion, so precisely gauging their weight requires special techniques and methods.
MULTIRAIL LiquidWeight is Schenck Process’ solution, a weighbridge specifically for the legal-for-trade weighing of liquids transported by rail.
Using MULTIRAIL LiquidWeight, the company says it is now possible to obtain a precise, verifiable (as per OIML R106-1) reading of the weight of tank wagons and even of entire trains. Depending on a customer’s specific requirements, the weighbridge system can generate figures with an OIML accuracy class of 0.2 or 0.5 for wagons with a weight of up to 150 tonnes. MULTIRAIL LiquidWeight has been specially designed with a concrete weighing sleeper that is fitted with high-precision sensors which transmit all forces and moments and which provide an ultra-accurate reading of the vertical force components.
A special feature is how the system is integrated into the track without the cutting of rails or use of foundations. This eliminates interference from unwanted wagon motion while they pass over the weighbridge. The system can be calibrated to suit wagon speeds of up to 10km/h as well as allowing trains to travel at the full speed permitted for a particular line if they are not to be weighed. Germany’s Federal Railway Authority (Eisenbahn-Bundesamt, EBA) has approved the use of the weighing sleeper.
