HMK-1901 Planetary Ball Mill

Overview

Planetary Ball Mill HMK-1901 is a lab ball mill designed and manufactured for requirement of fine milling industry.It integrates all traditional mixing and size reduction process and at the same time HMK-1901 planetary ball mill uses high centrifugal forces to generate high pulverization energy. It works efficiently and takes very short milling times. HMK-1901 Planetary Ball Mill is a convenient benchtop ball mill for size reduction and mixing purpose.Materials are milled in max 4 grinding stations.

The HMK-1901 is a benchtop model with 4 stations. It is equipped with 4 jars, 2 x 100 or 125 mL and 2 x 50 mL.

Applications
  • Planetary ball mills are widely applied to production fields of geology, mining, metallurgy, electronics, building materials, ceramics, chemicals, light industry, medicine, environmental protection, such as electronic ceramics, structural ceramics, magnetic material, lithium cobalt oxides, lithium manganate, catalyst, fluorescent powder, long afterglow luminescent powder, rare earth polishing powder, electronic glass powder, fuel cell, ceramic capacitor, oxygen zinc varistor, piezoelectric ceramics, nanometer materials, wafer ceramic capacitor, MLCC, thermistor(PTC,NTC), ZnO varistor, valve disc of arrester, strontium titanate ring varistor, ceramic filter, dielectric ceramics, piezoelectric transducer, piezoelectric transformer, chip resistor, thick film circuit, potentiometer, alumina ceramics, zirconia ceramics, ZnO powder, cobaltous oxide powder, Ni-Zn ferrite, Mn-Zn ferrite, and etc.
Principle
  • Planetary ball mill has four ball grinding tanks installed on one turntable. When the turntable rotates, the tank axis makes planetary movements, the balls and samples inside the tanks are impacted strongly in high speed movement, and samples are eventually ground into powder. Various kinds of different materials can be ground by the mill with dry or wet method. The size of ground powder can be reduced to as small as 0.1 micrometer.
  • The main disc is driven by a motor, the motor rotates and drives the disc rotates. There are four milling pots fixed on the main disc, they are under rotation and revolution at the same time. There are milling balls inside the milling pots and mill the sample to powder.
