Cross beater mill for fine and coarse size reduction
In the field of material processing, situations arise requiring the reduction of medium-hard and brittle materials, like coal or glass, to specific particle sizes. Challenges include maintaining consistent output fineness and efficient discharge for larger sample quantities, especially when processing heat-sensitive samples.

Adjustable speed for precise size reduction
The Cross Beater Mill SK 300 by Retsch is designed for both coarse and fine size reduction, catering to both batch and continuous operations. It excels in processing medium-hard and brittle materials, such as cement clinker, coal, and ores. This mill offers adjustable speed settings ranging from 2000 to 4000 min-1, allowing you to optimize the milling process for different applications. The device’s central locking mechanism and push-fit grinding insert simplify cleaning, while the optional cyclone unit aids in processing heat-sensitive samples by enhancing sample discharge and cooling. Its wide array of accessories, including various rotors and sieves, provide flexibility in achieving the desired final fineness with aperture sizes from 0.12 to 10 mm. The inclusion of a gravity outlet with 5L or 30L collecting vessels further supports efficient sample collection, making it suitable for industries like agriculture, geology, and environmental recycling.
