The A 11 is a batch mill for impact and cutting grinding by means of interchangeable tools. The high-grade stainless steel beater enables the impact grinding of hard, brittle, or non-elastic grinding materials and can be used for a Mohs hardness up to 6 (included with delivery). A cutting blade is available separately for pulverizing soft, fibrous materials. Moist and gluey materials can be pulverized by adding water.
The grinding chamber is made of glass fiber-reinforced PTFE with a stainless steel inlet (useful volume 80mL) and has excellent resistance to chemicals and tow temperatures. A polycarbonate grinding chamber with a useful volume of 250mL is also available separately.
