Its variety of materials offered, including heavy-metal free steel, its efficiency and safety makes this jaw crusher ideal for sample preparation in laboratories and industrial plants.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFunction Principle\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eThe Jaw Crusher BB 250 XL is a \u003cstrong\u003erobust and powerful forced-feed crusher\u003c\/strong\u003e. 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.\u003c\/p\u003e\n\u003cp\u003e\u003csmall\u003eSubject to technical modifications and errors\u003c\/small\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eProduct Advantages\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cul id=\"\"\u003e\n\u003cli\u003ehigh crushing ratio\u003c\/li\u003e\n\u003cli\u003efront door facilitates cleaning\u003c\/li\u003e\n\u003cli\u003einfinite\/continuous gap width setting\u003c\/li\u003e\n\u003cli\u003eoverload protection\u003c\/li\u003e\n\u003cli\u003ewide range of materials for contamination free grinding\u003c\/li\u003e\n\u003cli\u003eno-rebound feed hopper, removable\u003c\/li\u003e\n\u003cli\u003esample collector with safety switch\u003c\/li\u003e\n\u003cli\u003ecollecting receptacle with outlet for continuous operation\u003c\/li\u003e\n\u003cli\u003econnector for dust extraction\u003c\/li\u003e\n\u003cli\u003ecentral lubrication (optional)\u003c\/li\u003e\n\u003cli\u003esuitable for integration in automatic installations\u003c\/li\u003e\n\u003cli\u003especial version with automated sorting of undersize (3 fractions) and oversize (1 fraction)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eApplications\u003c\/td\u003e\n\u003ctd\u003ecoarse and pre-crushing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eField of application\u003c\/td\u003e\n\u003ctd\u003echemistry \/ plastics, construction materials, engineering \/ electronics, environment \/ recycling, geology \/ metallurgy, glass \/ ceramics\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFeed material\u003c\/td\u003e\n\u003ctd\u003emedium-hard, hard, brittle, tough\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSize reduction principle\u003c\/td\u003e\n\u003ctd\u003epressure\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial feed size*\u003c\/td\u003e\n\u003ctd\u003e\u0026lt;
