Advantages
Specially designed for large sample volumes
The HP-M1500 is the optimal pulverizing mill for grinding of big volume samples. Depending on the density of the material it can accept up to 1500 g of material smaller than 5 mm in diameter. The large capacity of the HP-M1500 carries many advantages like processing of high-surface material, improved sample representativeness, and more efficacious homogenization.
Proven technology for various material types
The HP-M1500 allows full control of grinding parameters and comes with an extensive set of standard and optional equipment. For that reason, the HP-M1500 is suitable for a wide range of different applications and material including ores, concentrates, electronic scrap, catalysts, lime stone, coal and many others. The HP-M1500 is designed for stand-alone operation, connection to a magazine or integration into automation.
Optimum grinding results
The disc mill HP-M1500 allows efficient pulverizing of varying and disparate sample material from soft to brittle. The grinding vessel is mounted on a precisely aligned spring supported system for effective horizontal oscillations without tumbling. The whirling movement accelerates the ring and stone via centrifugal forces and starts the grinding process based on impact and friction.
The HP-M1500 has been designed to guarantee sample comminution within the targeted grain size and the shortest possible processing time. Accordingly, all relevant machine parameters like, e.g., oscillatory frequency can be flexibly controlled using the machine HMI or the HERZOG Prepmaster software. Special milling sets with hardened chrome-steel stone and rings are available for susceptible samples to ensure a gentle pulverizing procedure. For particular applications, a continuous/open-circuit version of the HP-M1500 is offered.
Efficacious cleaning measures
The machine is self-cleaning after each sample preparation cycle. All parts of the machine being in contact with sample material are automatically cleaned by compressed air. Fine dust will be removed by an external dust collector (option) which is controlled by the machine PLC. Therefore, cross contamination between samples can easily be minimized. For special requirements, automatic solid cleaning of the grinding vessel with, e.g., quartz sand, or plastic granulate is available as an option. The cleaning material container can be flexibly placed next to the machine for comfortable refilling by the operator. Depending on the material types processed with the HP-M1500 can be also delivered with a wet cleaning functionality.
