RETSCH - High Energy Ball Mill Emax

High Energy Ball Mill Emax

General Information

The Emax is an entirely new type of ball mill for high energy milling. The unique

combination of high friction and impact results in extremely fine particles within the

shortest amount of time.

The high energy input is a result of an unrivaled speed of 2000 min-1 and the

optimized jar design. Thanks to the revolutionary cooling system with water, the

high energy input is effectively used for the grinding process without overheating

the sample. Due to the special grinding jar geometry, the sample is thoroughly

mixed which results in a narrow particle size distribution.

Unlike other high energy ball mills, the Emax is capable of continuous grinding

operation without interruptions for cooling down. This dramatically reduces the

grinding time. The high energy input in combination with the unique cooling system

provides perfect conditions for effective mechanical alloying or grinding down to the

nanometer range.

A wealth of safety features such as the integrated safety closure of the grinding jar,

temperature control with automatic start/stop system, and integrated imbalance

controls make operation of the bench-top mill Emax very user-friendly.

Application Examples

alloys, bones, carbon fibres, catalysts, cellulose, cement clinker, ceramics,

chemical products, clay minerals, coal, coke, concrete, fibres, glass, gypsum, iron

ore, kaolin, limestone, metal oxides, minerals, ores, paper, pigments, plant

materials, polymers, quartz, semi-precious stones, sewage sludge, slag, soils, tea,

tobacco, waste samples, wood, ...
