1. Pretreatment of solid materials
Solid materials, sludges and suspensions are fully characterised and pretreated to allow further processing. After full characterisation (WDXRF, ICP-OES, microwave digester, TXRF) metal-containing solid materials, sludges and suspensions are pretreated to allow further processing.
Available equipment: ball mill, mixer mill, mortar grinder, vibratory sieve
Planetary ball mill Fritsch Pulverisette 7
The Fritsch Pulverisette 7 is a planetary ball mill (micro mill) for the milling of solid material using impact force. Grinding bowls and balls are available in tempered steel and stainless steel and various sizes. Depending on the material, powders of less than 0.1 μm can be obtained in both dry and wet conditions. The rotational speed of the main disk can be varied between 100 and 1000 rpm.
Mortar grinder Fritsch Pulverisette 2
Automated mortar grinder for wet (suspension) and dry grinding, mixing and homogenisation of organic and inorganic samples, using pressure and friction without thermal load, suitable for hard, medium-hard, soft, brittle, fibrous and abrasive materials. The fineness of the obtained product is 10-20 μm.
Vibratory sieve shaker Fritsch Analysette 3 Pro
The Fritsch Analysette 3 Pro is a vertically oscillating shaking sieve system for sieving dry and wet samples with quantities up to 2 kg into different particle sizes ranging between 5 μm and 63 mm.
Ball mill Retsch Mixer Mill MM 400
The Mixer Mill MM 400 is a multipurpose ball mill, specifically for dry and wet grinding, mixing and homogenization of small sample amounts (powders and suspensions). Two samples can be grinded at the same time, with a volume of 0.2 to 20 mL per sample. The final fineness of the powder is lower than 10 μm.
