How does an agate grinder work? Planetary ball milling principle for efficient sample processing

Sample pretreatment is a crucial step in determining the accuracy of analysis results in industries such as soil, geology, environmental protection, agricultural product testing, and resources and environment. The agate grinder efficiently and uniformly grinds samples through mechanical force, meeting the preparation needs of various types of samples and providing a reliable sample foundation for subsequent heavy metal analysis, element detection, and physicochemical property testing, significantly improving data accuracy and experimental efficiency.

Working principle of agate grinder

The agate grinder is based on the principle of planetary ball milling, and achieves multidimensional mechanical action on the sample through high-speed relative motion between the grinding tank and the main disk. Its core working mechanism includes:

Multi dimensional force composite effect: By comprehensively utilizing impact force, shear force, and friction force, effective treatment of samples with different characteristics such as brittleness, fiber, and low to medium hardness can be achieved;

Planetary transmission structure: The main disk and grinding tank rotate at high speed in reverse at a ratio of 1:2, generating strong eddy currents and ball milling effects to ensure sufficient and uniform sample grinding;

Multiple operating modes: supporting various working modes such as one-way continuous, one-way interval, two-way alternating interval, and timed stop, to meet the processing needs of different samples.

This device achieves dry or wet grinding through mechanical force control, avoiding chemical contamination, and is particularly suitable for analysis scenarios with high purity requirements.

Technical advantages and core functions
