Overview
The DECO DECO-PBM-S-0.4L Soil Grinder is a highly efficient Sample Handling device designed for the analysis of heavy metals in soils. The device uses an agate grinding tank, which rotates in reverse around its own axis while rotating around the axis of the turntable. The samples collide and rub with each other through high-speed motion to achieve crushing, grinding, mixing and dispersion. Supports dry grinding, wet grinding, vacuum grinding and other methods, and can work two or four grinding tanks at the same time.
Features
1. Various grinding tank materials are available: cemented carbide, stainless steel, tungsten carbide, agate, corundum, zirconia, ceramics.
2. Support a variety of grinding methods: dry grinding, wet grinding, vacuum grinding.
3. Can work multiple grinding tanks at the same time: two or four can work at the same time.
4. Stepless speed regulation function: Rotation speed stepless adjustment is realized by brand frequency converter.
5. Automated operation: Automatic setting of forward and reverse rotation and automatic shutdown.
6. Flexible working environment: optional vacuum, inert gas, low temperature or high temperature ball milling.
7. High Accuracy Discharge: The minimum discharge particle size can reach 0.1μm.
8. Long-term Operating Capacity: Continuous Operating Time up to 72 hours.
9. Supporting screening equipment: equipped with electric Sieve Shaker, up to seven layers of sieves, sieve range 20-200 mesh.
Principle
Soil Grinder rotates around its own axis while rotating around the turntable axis through the grinding tank. The samples in the tank collide and rub with each other in high-speed motion to achieve the purpose of crushing, grinding, mixing and dispersing the samples. The transmission mode adopts belt and gear transmission to ensure stable and efficient movement.
Applications
Soil heavy metals analysis, sample crushing, grinding, mixing and dispersion
Steps
1. Select the grinding tank material and capacity (such as agate tank 50ml or 100ml).
2. Load the sample to ensure that the material and grinding medium do not exceed two-thirds of the tank volume.
3. Rotation speed: revolution 0-450rpm, rotation 0-850rpm.
4. Stepless speed regulation through the frequency converter, and set up forward and reverse rotation and automatic shutdown.
5. Set running time: total time 1-9999min, alternating time 1-9999min.
6. Start the device to grind.
7. After the grinding is completed, use the matching Vibration sieve for screening (sieve 20-200 mesh).
Notice
• Feed particle size limit: Soil material does not exceed 10mm, Miscellaneous material does not exceed 3mm.
• Loading volume control: the material and grinding medium do not exceed two-thirds of the volume of the grinding tank.
Voltage requirements: 220V AC power supply is used.
• Running time setting: continuous operation for no more than 72 hours, timer range 0-9999h.
• environment selection: according to the requirements of vacuum, inert gas, low temperature or high temperature ball milling environment.
• Screening operation: When using an electric Sieve Shaker, the sieve diameter range is 20-200 mesh.
