Description
Soil Grinding and Screening Machine
Product Introduction
This machine is designed for heavy metal analysis in soil, equipped with 4 agate grinding jars. The sealing pressure of the agate grinding jars is adjustable via a graduated scale. The grinding jars rotate reversely around their own axes while revolving around the turntable axis. Samples inside the jars collide and rub against each other at high speed, achieving sample crushing, grinding, mixing and dispersion. It supports dry grinding, wet grinding and vacuum grinding. Two or four grinding jars can work simultaneously at a time.

Working Principle
This machine is used for heavy metal analysis in soil, equipped with 4 agate grinding jars. The sealing pressure of the agate grinding jars is set by a graduated scale. The jars revolve around the turntable axis and rotate reversely around their own axes at the same time. Samples in the jars collide and rub against each other during high-speed movement, so as to crush, grind, mix and disperse samples. It can be used for dry grinding, wet grinding and vacuum grinding. Two or four grinding jars can operate at the same time.

This powered benchtop mill with integrated glove box requires adherence to electrical safety and sample containment protocols. The rotating jar assembly and motorized drive present pinch and entanglement hazards during operation.
- Electrical Grounding: Connect the mill to a grounded outlet and verify the control box is free from moisture before powering on.
- Glove Box Integrity: Inspect the glove box seals and gloves for punctures or leaks prior to processing hazardous or air-sensitive materials.
- Jar Sealing Adjustment: Adjust the jar sealing pressure using the graduated scale, ensuring it does not exceed the maximum indicated setting to prevent jar failure.
- Sample Containment: Always operate the mill with the glove box door closed when grinding samples containing heavy metals to prevent aerosol release.
Follow these steps to safely load and operate the mill in glove box mode. Proper sealing and speed selection minimize risk of sample leakage or mechanical damage.
Required Equipment: Agate Grinding Jars, Glove Box Enclosure, Control Box with Variable Speed Controller
- Inspect Equipment
Inspect the glove box seals, grinding jar threads, and electrical cables for any visible damage before starting. - Load Sample and Jar
Load the soil sample and appropriate grinding media into the agate jar, then secure the lid and tighten it to the indicated sealing pressure. - Install Jar in Mill
Place the sealed jar into the mill holder and lock it in position by rotating the retaining ring until it clicks. - Close and Purge Glove Box
Close the glove box door and, if processing air-sensitive samples, purge the interior with inert gas for at least two minutes. - Set Operational Parameters
Set the desired rotation speed and grinding time using the control box, ensuring the speed does not exceed the jar's rated maximum. - Start Grinding Cycle
Press the start button to begin the grinding cycle and monitor the operation for abnormal noise or vibrations. - Unload Jar After Cooling
After the cycle ends, allow the jar to cool for five minutes before opening the glove box and removing the jar.
What is the trade-off between achieving 0.1 μm fineness and throughput on the XQM-0.2S planetary ball mill with its 90W motor?
The XQM-0.2S can achieve a discharge particle size as fine as 0.1 μm for soil samples, as stated in the specifications. However, the 90W motor inherently limits batch size and grinding speed; reaching submicron fineness typically requires extended grinding times and smaller sample volumes to maintain effective planetary motion.
Can the XQM-0.2S be used with stainless steel grinding jars for soil heavy metal analysis, or are agate jars required?
For soil heavy metal analysis, agate jars are mandatory to avoid metallic contamination. The XQM-0.2S standard configuration includes four 250 ml agate grinding jars and 700 agate grinding balls; using stainless steel or other metal jars would introduce metal ions and compromise trace heavy metal detection.
What are the specific handling and infrastructure requirements for operating the XQM-0.2S glove box mill, particularly regarding jar sealing and control box placement?
The XQM-0.2S is a mini glove box type mill designed for operation inside a glove box; its main unit dimensions are 390×220×270 mm and the separate control box is 200×180×240 mm. The sealing pressure of the agate grinding jars is adjustable via a graduated scale and must be set appropriately before grinding to prevent leaks, especially when working under vacuum or inert atmosphere.
The Atomfair XQM-0.2S planetary ball mill offers a compact glove-box design with variable speed up to 1160 rpm, enabling efficient soil grinding for heavy metal analysis. It integrates both grinding and sieving, but requires careful attention to feed size limitations and batch capacity.
Positive
- Multi-Mode Grinding Flexibility: Supports dry, wet, and vacuum grinding with adjustable sealing pressure, enabling versatile sample preparation for different analysis requirements.
- Integrated Sieving Capability: Built-in electric screener with multi-layer sieves allows immediate particle size separation from 20 to 200 mesh, streamlining the workflow.
Trade-offs
- Feed Size Constraint: Maximum feed particle size is 10 mm for soil and 3 mm for other materials, requiring pre-crushing for larger samples.
- Limited Batch Capacity: Standard configuration includes four 250 ml grinding jars, total capacity of 1 liter per batch, suitable for small-scale lab use.
