Pulverising mills - fast, fine pulverising of mineral samples

The HP-M1500 Automatic Pulverising Mill is a large-capacity, fully automated disc-mill designed for grinding up to 1.5 kg of sample material. The HP-M1500 is also available with a 1500 ccm chromium steel grinding vessel or a smaller 500 ccm chromium steel grinding vessel. It efficiently processes minerals, ores, and other materials for analytical purposes such as X-ray fluorescence diffractometry and other analytical processes.

The HP-M1500 can be operated as a standalone machine or connected to an 8 or 30-position sample magazine or linear or robot automation for unattended operation and to further streamline your sample processing. Optional extras to further enhance your efficiencies and accurate sample processing include automated grinding aid dosage (liquid), loadcell for input and output weight measurement, and quartz or glass bead flushing of the grinding vessel.

Sample quality and integrity is paramount which is why our HP-M1500 is rigorous in its automated cleaning. After milling is completed and the pulverised material is discharged into the sample cup, and the cup presented back to the operator with the product, automatic cleaning with compressed air is initiated prior to the machine accepting the next sample. Fine dust is removed by an external dust extraction system (option), which can be controlled via the machine programmable logic controller (PLC). It is efficient, and it also minimises the risk of carryover between successive samples. As an option quartz or glass bead flushing is available to flush the grinding vessel between samples.

Our HP-M1500 keeps your operator safe from exposure to dust, noise, and heavy lifting. It also removes the risk to the operator that comes from dropping a large bowl or puck. This means your operators are free to work safely and comfortably without the need for wear hearing protection, glasses, face masks or steel cap shoes.  

The HP-BTM is a modular machine that is designed for the preparation of coarse ores, minerals and similar materials in the range of 1 to 15 kg input weight with a particle size of less than 50 mm to split off a representative sample of approx. 250g to 1,000g of finely pulverized sample material for analysis.

The machine consists of two individual working units: crusher/ linear Splitter (HP- BT) and mill HP- M1500. The crusher/linear splitter HP-BT is equipped with a manual sample input for coarse material, a weighing system, a lift for transporting the sample into the internal in feed position, a jaw crusher, a vibration feeder, a linear splitter as well as an output for residue material and an input for empty sample cups. The HP-M1500 pulverising mill includes a sample take over the device from the crusher to the mill, a cup lift for transporting the sample into the grinding vessel, a sample outlet device, a cup weighing unit and a cup output transport.

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 pulverised material for further processing. As an option, the HP-BTM2 can be fitted with a 5,10 or 15 position loading magazine, freeing up valuable operator time.

The HP-BTM2 is a modular machine that is designed for the preparation of coarse ores, minerals and similar materials in the range of 1 to 15 kg input weight with a particle size of less than 50 mm to split off a representative sample of approx. 250g to 1,000g of finely pulverized sample material for analysis. To eliminate operational risks, the sample weights are monitored after each preparation step.
The machine consists of the following main individual working units: Crusher/ linear Splitter (HP-BT), cup handling device (HK-RX3), 2x HP-M1500 pulverising mills. 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., for the preparation of fused beads for chemical analysis by XRF.

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. As an option, the HP-BTM2 can be fitted with a 5,10 or 15 position loading magazine, freeing up valuable operator time.
