A perfect solution for the mining industryHerzog Maschinenfabrik have recently introduced a new combined crusher, splitter and pulverising mill for coarse ores, drill cores, minerals and other similar materials. The HP-BTM is the perfect solution for harsh environments due to its robust construction. Its compact design also ensures easy installation in small compartments.
The sample input weight has a range of 1 to 15 kg, with a maximum input particle size of 50mm. The general application of the HP-BTM is particle size reduction and sub-sampling in order to obtain a representative sample for final analysis via X-ray fluorescence (XRF).
The crusher/splitter unit is equipped with a manual sample input for coarse material and a weighing unit. The material is transported by a lift into the internal in-feed position to the jaw crusher. After crushing, the material is split using a linear splitting device. A vibration feeder ensures a constant material flow into the subsequent splitter unit. Based on the weight of the input material the desired splitting ratio of sample and residue material is automatically calculated. Therefore, the HP-BTM will always provide the desired absolute sample weight independent from the input weight. The design of the splitter and the control algorithm are according to relevant ISO standards.
The pulverising unit includes a transport device from the splitter to the mill. The sample material is weighed before and after the pulverising process, and the sample cup is transported to the output conveyor belt. After each preparation cycle the system is cleaned by compressed air. The machine is totally enclosed, sound isolated and requires minimum operator assistance.
Easy to modify
Due to the modular design the machine is easily modified to accommodate an additional pulverising mill to increase the sample throughput (HP-BTM2). In this case the sample cups within the pulverising unit are transported using a swivel-mounted two axis handling system with a robot gripper (HR-RX3). Furthermore, an input magazine for buckets and a dosing unit for discharge of the pulverized material into smaller cups or vials can be included.
