Retsch® Jaw Crusher BB 300 with Manganese Steel Breaking Jaws & Stainless Steel Wearing Plates, 220 V, 60 Hz, 20.054.0005Designed for rapid, effective crushing and pre-crushing of medium-hard, brittle and tough materials. Other breaking jaws and wearing plates materials are available to meet your needs, even a unit with heavy-metal free steel. This unit can be used either batch-wise for small samples or operated continuously for larger amounts. Belleville spring washer protects the unit from overloads and along with the central lubrication guarantees a long service life. Efficiency and safety makes this instrument ideally suited to sample preparation in laboratories and industrial plants. Robust and powerful forced-feed allows material to pass through the no-rebound hopper and enter the crushing chamber. The size reduction 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. As soon as the sample is smaller than the dischare gap width, it falls into a removable collector. The continuous gap width setting with scale ensures optimum size reduction in accordance with set gap width.
