Glen Mills Inc is the primary supplier of equipment to comply with the Mechanical Sample Preparation section of "Procedures for the Determination of Levels of Regulated Substances in Electrotechnical Products" produced by the IEC ACEA ad hoc Working Group. Download Version 1.0 (PDF 605 kb). This standard is the precursor to RoHS (Reduction of Hazardous Substances) and WEEE (Waste Electronic and Electrical Equipment) legislation being proposed in Europe and the US.
Glen Mills provides one-stop shopping for the three major components of the sample prep section: SM2000 for coarse grinding, Turbula T2F for homogenizing, ZM200 for fine grinding.
|
 Coarse grinding: The SM2000 Heavy Duty Knife Mill is used for coarse grinding step. Two passes through the mill are recommended by the specification. Our clients have experimented with various screen sizes and have found that the 10mm and 4mm screens generally give the best results. Screens from 20mm down to 0.25mm are available.

 Homogenizing:The Turbula®T2F is used to provide a completely homogenized mix prior to fine grinding. A sub-sample is removed from the mixture after the mixing cycle, this sub-sample is completely representative of the bulk sample. More info on Turbula® T2F click here.

 Fine grinding: The sub-sample removed from the Turbula® is further processed in the ZM200 Ultra Centrifugal Mill. A 250 micron (0.25mm) tungsten carbide coated screen is recommended along with a 6-tooth tungsten carbide coated rotor. A pre-grind with a 1mm screen maybe required for some materials. Cryogenic grinding is also an option with this mill, certain materials will require freezing prior to processing to ensure they are brittle enough to be ground. Optional extras include a vibratory feeder and cyclone collecting vessel for larger quantities. More info on ZM200 click here.
