Retsch Jaw Crusher BB 400 XL Retsch Mill NEW PRODUCT
"The Jaw Crusher BB 400 XL is used for the rapid, effective crushing and pre-crushing of medium-hard, hard, brittle and tough materials. Its variety of materials offered, including heavy-metal free steel, its efficiency and safety makes it ideal for sample preparation in laboratories and industrial plants.
For small amounts of sample the BB 400 XL is used batch-wise; for larger amounts it can be operated continuously. Control of the gap width and zero point adjustment allow for reproducible results.
Thanks to the modular construction of housing and frame this jaw crusher is suitable for a wide range of applications." (RETSCH)

*depending on feed material and instrument configuration/settings
"The Jaw Crusher BB 400 XL is a robust and powerful forced-feed crusher. The feed material passes through the no-rebound hopper and enters the crushing chamber.
Size reduction takes place in the wedge shaped area between the fixed crushing arm and one moved by an eccentric drive shaft. The elliptical motion crushes the sample which is moved towards the crushing gap under gravity.
As soon as the sample is smaller than the discharge gap width, it falls into a removable collector within the jaw crusher. The continuous gap width setting with scale ensures optimum size reduction in accordance with the set gap width." (RETSCH)
