A vertical planetary ball mill is a laboratory grinding machine designed for fine grinding, mixing, and homogenizing various materials. It operates through the simultaneous rotation and revolution of grinding jars, generating strong impact and friction forces to achieve efficient particle size reduction.
The XQM Series Vertical Planetary Ball Mill is suitable for grinding ceramics, minerals, chemicals, metal powders, battery materials, and other laboratory samples. It can process various dry and wet materials, depending on the grinding jar and ball materials selected.
A planetary ball mill uses both rotation and revolution to generate high-energy grinding forces, making it suitable for fine grinding and small-batch laboratory applications. Conventional ball mills mainly rely on the rotation of a grinding cylinder and are commonly used for larger-scale material processing
Yes. Vertical planetary ball mills can generally perform both dry and wet grinding. Dry grinding is suitable for moisture-sensitive materials, while wet grinding can help reduce dust and improve dispersion. The appropriate method depends on the material properties and experimental requirements.
Grinding jars and balls should be selected according to material hardness, chemical compatibility, contamination requirements, and desired particle size. Common materials include stainless steel, zirconia, alumina, and tungsten carbide. Selecting suitable grinding media helps improve grinding efficiency and minimize sample contamination.
An automatic oxygen bomb calorimeter is a laboratory instrument used to determine the calorific value of combustible materials. It measures the heat released when a sample burns in a sealed oxygen-filled vessel under controlled conditions. The automated system helps simplify testing procedures and improve measurement consistency.
The JZLR-9000 Series Automatic Oxygen Bomb Calorimeter is designed for calorific value testing of suitable combustible materials, such as coal, coke, biomass fuels, and certain solid waste samples. Sample compatibility depends on the instrument configuration, testing method, and safety requirements.
An oxygen bomb calorimeter works by burning a weighed sample in a sealed vessel filled with high-pressure oxygen. The heat released during combustion causes a measurable temperature change in the calorimetric system. The instrument uses this temperature change and its calibrated heat capacity to calculate the sample’s calorific value.
Automatic oxygen bomb calorimeters offer simplified operation, automated data acquisition, precise temperature monitoring, and efficient calorific value calculation. These features help reduce manual intervention, improve testing consistency, and support routine laboratory analysis.
