Jaw Crusher BB 50 RETSCH reliable sample preparation

The Jaw Crusher BB 50 is a robust and powerful forced-feed crusher. The feed material passes through the no-rebound hopper and enters the crushing chamber. Size reduction in the Jaw Crusher takes place in the wedgeshaped area between the fixed crushing arm and one moved by an eccentric drive shaft. The elliptical motion crushes the sample which then falls under gravity.

Retention Time in Continuous Vibratory Ball Milling

2020-5-25  Discussion of Results: The experimental data reported in this paper show that for a vibratory ball mill operating continuously in open circuit, at constant power input, size moduli of the products are determined by total retention time within the mill, regardless of feed rate. Thus, for a continuously operating low-level discharge mill retention time determines how long any given particle is subjected to the mill action.
