BB 400 Jaw Crusher

Overview

The Jaw Crusher BB 400 is a robust, forced-feed jaw crusher for rapid, effective crushing and pre-crushing of medium-hard, hard, brittle and tough materials. It is used for sample preparation in laboratories and industrial plants and is offered in a variety of materials including heavy-metal free steel. Technical specifications include a jaw width of 220 x 90 mm, material feed size < 220 x 90 mm, final fineness < 2 mm, and collector capacity 10 l. Material of grinding tools: manganese steel, tungsten carbide, heavy-metal free steel. Gap width is continuously adjustable with scale and zero point adjustment (Gap width setting: 0 1 30 mm; gap width display: scale; zero point adjustment: yes). Wearing rate display: yes, up to minus 10 mm. Drive is a 3-phase motor with drive power 5.5 kW; electrical supply data: different voltages; power connection: 3-phase; protection code: IP 55. Overall dimensions W x H x D closed: 695 x 1399 x 719 mm; net weight: ~ 400 kg; standards: CE. Base frame: vario frame (adjustable for continous crushing). The BB 400 is intended for coarse and pre-crushing and for sample preparation tasks, handling medium-hard to tough feed materials. It can be used batch-wise for small sample amounts and continuously for larger amounts, with a removable collecting receptacle and outlet for continuous operation. Fields of application explicitly listed are chemistry / plastics, construction materials, engineering / electronics, environment / recycling, geology / metallurgy, and glass / ceramics. Application examples given include alloys, basalt, cement clinker, ceramics, chamotte, coal, coke, construction materials, feldspar, glass, granite, minerals, quartz, ores, oxide ceramics, rocks, silicon and slag. Operational and safety features that support these use cases include a no-rebound removable feed hopper, front door for cleaning, overload protection, sample collector with safety switch, connector for dust extraction, and an optional special version with automated sorting of undersize (3 fractions) and oversize (1 fraction) (2 2 6 mm available).
