Cryogenic Grinding Retsch

Grinding component: 1 25mm steel ball each Feed material: Quartz gravel particles approx. 4.0 – 6.0mm Feed quantity: 8ml Frequency: 30 Hz Example 2: Emission value with regard to workplace L pAeq = 66,3 dB(A) Operating conditions: Receptacle: 4 5ml steel grinding jar Grinding component: 2 8mm tungsten carbide balls each

Apr 10, 2013 The grinding ball moves freely inside the grinding jar which allows for thorough pulverisation of the sample, in contrast to other cryogenic mills with differently shaped grinding tools. Based on an extensive dialogue with users of the CryoMill, Retsch was able to integrate a variety of suggestions into the further development and optimisation

Mar 01, 2018 Cryogenic grinding in the CryoMill offers the advantage of continuous cooling of the grinding jar with LN2, thereby reducing the temperature of jar and sample to -196 C within minutes. This consistent temperature is guaranteed even for long grinding times without the

Retsch CryoMill, 100-240 V, 50/60 Hz The CryoMill is tailored for cryogenic grinding. The grinding jar is continually cooled with liquid nitrogen from the integrated cooling system before and during the grinding process. Thus the sample is embrittled and volatile components are preserved

The CryoMill is a cryogenic grinder designed with user safety in mind. The liquid nitrogen flows through the closed system and the user never comes into direct contact with LN 2 which ensures a high degree of operational safety. The automatic cooling system guarantees that the grinding process is not started before the sample is thoroughly cooled

The Autofill system avoids direct contact with LN2 and makes cryogenic grinding very safe. Its versatility (cryogenic, wet and dry grinding at room temperature) makes the CryoMill the ideal grinder for quantities up to 20 ml. Application Examples animal feed, bones, chemical products, food, hair, oil seeds, paper, plant materials, plastics

RETSCH has created the CryoMill as an advancement of the MM 400, offering the benefit of constant cooling of the grinding jar with liquid nitrogen, keeping the temperature of the sample and the jar at −196 C even during long grinding processes. In case intermediate cooling is needed, it is possible to program cycles of grinding and cooling

The optimum solution for these types of materials is cryogenic grinding. It involves embrittlement of the material with dry ice or liquid nitrogen which substantially improves the breaking behavior. RETSCH offers a wide range of laboratory mills suitable for cryogenic grinding: CryoMill, Mixer Mill MM 400, Ultra Centrifugal Mill ZM 200, Knife Mill GRINDOMIX GM 300

The CryoMill is a cryogenic grinder designed with user safety in mind. The liquid nitrogen flows through the closed system and the user never comes into direct contact with LN 2 which ensures a high degree of operational safety. The automatic cooling system guarantees that the grinding process is not started before the sample is thoroughly cooled

RETSCH offers a range of laboratory mills which allow for gentle and efficient cryogenic sample preparation. Their use considerably reduces both the cost and labor required for low-temperature grinding. A selection of suitable accessories ensures that the grinding process is carried out safely
