The Extec X44 SBS Cone Crusher: A Robust Solution for Secondary Crushing

The Extec X44 SBS (Sized By Specification) cone crusher stands as a significant model in the history of mobile crushing and screening equipment. Representing a collaboration between Extec Screens & Crushers and Rock Processing (before 's full acquisition of Extec), the X44 incorporated advanced cone crushing technology into a highly mobile tracked chassis, designed specifically for demanding secondary crushing applications.

Core Specifications and Design Philosophy

Built around the proven CH440 (previously known as Hydrocone H4800) كسارة مخروطية, the X44 was engineered for high productivity and efficient reduction of hard, المواد الكاشطة. specifications defining its capability include:

1. Cone Crusher Unit: CH440 / H4800 Hydrocone.
2. Cone Head Diameter: 44 بوصة (1120 مم).
3. محرك: A robust Caterpillar C13 Acert diesel engine, generating 328 كيلوواط (440 hp). This provided ample power for both the crushing process and hydraulic systems driving conveyors and tracks.
4. فتح الأعلاف: Capable of accepting feed material up to approximately 8.5 بوصة (215 مم) في الحجم, depending on feed arrangement and material characteristics.
5. Crushing Chamber Options: Offered various chamber configurations (على سبيل المثال, المفوضية الأوروبية - Extra Coarse, ج - Coarse, م - Medium, F - Fine) to optimize performance for different feed sizes and desired end products.

6. إعداد الجانب المغلق (CSS) يتراوح: Wide hydraulic adjustment range, typically from approx. 10mm to 40mm (3/8” to 1 5/8”), allowing precise control over product size without needing to change concaves/mantles immediately.
7. سعة: Production rates varied significantly based on feed material type, تدرج, chamber selection, وإعدادات CSS. Under optimal conditions with suitable feed, potential throughput could reach several hundred tonnes per hour.
8. Product Conveyor: High discharge conveyor with excellent clearance under the crusher discharge point. Features included variable speed control, high abrasion-resistant belting, hydraulic raising/lowering for transport and maintenance access, and often a hydraulic folding function.
9. التنقل: Mounted on a heavy-duty tracked undercarriage providing good stability during operation and mobility around site or between sites.
