техническа информация

Език:

Мелницата Emax е напълно нова концепция на топкова мелница с високоенергийно смилане. Уникалната комбинация между интензивно триене и удар позволява смилане до екстремно финни частици за много кратки времена.

  • по-бързо и по-фино смилане от всяка друга топкова мелница
  • скоростта от 2000 об/мин позволява ултрабързо смилане на пробата
  • водното охлаждане позволява непрекъснат режим на работа без спирания за охлаждане
  • температурен контрол по време на смилане
  • тесен диапазон на големината на смлените частици благодарение специалния дизайн на смилащия цилиндър, подобряващ хомогенизирането на пробата

Faster - Finer - Cooler - the most powerful Ball Mill

  • Max. speed 2000 rpm
  • Up to 5 mm feed size and 0.08 µm final fineness

Unique grinding jar geometry

The High Energy Ball Mill Emax combines high-frequency impact, intensive friction, and controlled circular jar movements to a unique and highly effective size reduction mechanism.

No more cooling breaks Highly Efficient
Cooling System

The greatest challenge when developing a high energy ball mill is keeping the temperature under control as the enormous size reduction energy leads to considerable heat built-up inside the grinding jar.

RETSCH solved this problem with an innovative integrated water cooling system. Hence, the Emax usually doesn’t require cooling breaks which are typical for long-term processes in conventional ball mills, even at low speed.

In the Emax the cooling system cools the grinding jars via the jar brackets. This is very effective because heat is more easily discharged into water than into air. The user can choose between 3 cooling modes: in addition to the internal cooling, the mill can be connected to a chiller or the tap to further reduce the temperature.

Grinding jars in 3 different materials

Grinding jars in 3 different materials

Available grinding jar sizes are 50 ml, 80 ml and 125 ml, materials include stainless steel, tungsten carbide and zirconium oxide, ensuring contamination-free sample preparation. Grinding balls are available in sizes from 0.1 mm to 25 mm, depending on the material.

Aeration lid

Aeration lid

RETSCH offers a special aeration lid for the grinding jars designed for applications where a special atmosphere is to be maintained in the ball mill jar.
