Automatic milling and pressing system (AMP)
The fully automatic grinding and pressing system can be used to convert bulk material samples into test specimens for an XRF or XRD analyzer.
The fully automatic transport of bulk material samples to the laboratory is carried out by our Pneumatic Tube Systems, which are individually designed and manufactured for your spatial conditions. The material sample transferred from the sampling system is automatically filled into a conveying box. It is then transported to the desired location via a transport tube system, which can be several hundred meters long. There, the conveyor box is automatically opened and the material sample is emptied. The sample obtained in this way can be further processed in the automatic sample preparation systems that we also manufacture, such as the automatic grinding and pressing system for the production of test specimens for XRF/XRD analysis.
The control system of a Pneumatic Tube System is of particular importance, as it is not only responsible for the correct functioning of the individual machines and their interaction, but must also take over the sample documentation. The control system must therefore be adapted to your operational requirements on the basis of our standard procedures.
The manual sending/receiving station is used by the operator to manually insert or remove feed cans from the conveyor tube. At the manual sending station, the operator fills the feed can with sample material, closes it and places it in the station’s input device. After manually locking the door, the feed box can be removed. When used as a receiving station, the door must be opened after receiving the feed box and the feed box removed. A manual lid puller, which is available as an option, makes it easier to open the feed box.
The fully automatic sending station can be used to fill a bulk material sample into a feed can without manual intervention and feed it into the Pneumatic Tube System’s transport tube. For this purpose, the empty conveying box is automatically removed from the conveyor tube, opened and placed under a sample material filler neck. After filling with sample material, the feed bush is closed again and inserted into the guide tube. A geared motor and several pneumatic cylinders are used to reliably position the conveyor bush at the internal stations.
Depending on the sampling situation, mixers and dosing devices can be connected upstream of the fully automatic sending station. The mixer mixes the subsamples taken by the sampler. The dosing device in turn separates a partial quantity from this collective sample to ensure a sufficient quantity for the subsequent processes in the laboratory.
The fully automatic receiving station accepts the sample-filled feed can from the conveyor tube and empties it. To do this, the feed can is opened upside down in the receiving station so that the bulk material it contains can run out freely into a collecting funnel. Once the feed box and the collecting hopper have been emptied, they are blown out using air nozzles. Finally, the feed box is closed again and is ready to be discharged into the conveyor pipe. The fully automated processes are carried out in the station using pneumatic cylinders.
To be able to connect several transmitter stations to a receiver station in the laboratory, for example, it is necessary to install guide tube switches. Up to four transmitter stations can be connected to one receiver station with the guide tube switch. A geared motor is used to position the preselected direction of travel.
Precision guide tubes, tube bends, tube connectors, guide tube contacts, guide tube bushes, side channel compactors and various fastening elements are also required for the safe and reliable operation of the Pneumatic Tube System.
