Designed for large volume samples
To cover a broad range of applications the input weight can be between 1 and 15 kg. The maximum particle size, which can be introduced in the HP-BTM2, is 50 mm. The general application of the HP-BTM2 is particle size reduction and sub-sampling in order to obtain a representative sample for final analysis with X-ray fluorescence. To eliminate operational risks, the sample weights are monitored after each preparation step.

Modular design
The machine consists of the following main individual working units: Crusher/ linear Splitter (HP-BT), cup handling device (HK-RX3), 2x mill HP-M1500. The first preparation step is a size reduction done by a jaw crusher. A vibration feeder which is located below the crusher ensures a constant material flow into the subsequent linear splitting unit. The linear splitter allows a representative sub-sampling of adjustable volumes into two cups (1.5 l). Calculating the desired splitting ratio (sample/residue material) is done automatically. Residual material is discharged via a vibration feeder to a waste bucket or a de-dusting system. The cup handling between the single compounds is done by a swivel- mounted 2 axis handling device with a robot gripper. These mills allow fine grinding of the crushed material to a particle size suitable for creating a final sub-sample. This pulverized sub-sample can be used, e.g., forthe preparation of fused beads for chemical analysis by XRF.

Perfectly developed for the mining industry
The operator selects one of the available individual programs by pushing a button on a separate front panel. The input flap will open automatically. All further preparation steps including cleaning are fully automatic without the need for operator`s invention. The operator just removes the ready ground material for further processing.
