Frequently Asked Questions

Where is Retsch located?

Retsch is located in Haan, Germany, and their headquarters have recently been modernized and an application laboratory has been put into operation. Retsch celebrated its 100th anniversary in the same location and also expanded their product range with their line of big crushers and grinders, Retsch XL.

What is the CryoMill?

The CryoMill is an advanced laboratory ball mill designed for cryogenic grinding. It features an integrated cooling system that constantly cools the grinding jar with liquid nitrogen, preserving volatile components and embrittling the sample for efficient grinding.

What is the difference between a ball mill and a rod mill?

The main difference between a ball mill and a rod mill is that the former has a smaller processing capacity and a finer particle size than the latter. The finesse of the material milled by the ball mill is 0.074mm-0.4mm, while particles from the rod mill can achieve a fineness of 0.833-0.147mm. Additionally, the rod mill requires more power to operate compared to a ball mill due to its different shape; the barrel of the rod mill is a long cylinder type while the barrel of the ball mill is usually cone shaped.

What are the different types of ball mills?

Ball mills come in two varieties, dry and wet. Dry mills are characterized by their longer drum length compared to its diameter, while wet mills typically have a shorter drum length compared to its diameter. Tube mills are also available, which feature a drum length that is greater than 1.5 times the diameter.

What industries commonly use sieving equipment?

Sieving equipment is widely used in industries including food, pharmaceuticals and construction materials for quality control and particle size analysis.
