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) triturador de cone, the X44 was engineered for high productivity and efficient reduction of hard, materiais abrasivos. specifications defining its capability include:

1. Unidade britador de cone: CH440 / H4800 Hydrocone.
2. Diâmetro da cabeça do cone: 44 polegadas (1120 milímetros).
3. Motor: A robust Caterpillar C13 Acert diesel engine, gerando 328 kW (440 HP). This provided ample power for both the crushing process and hydraulic systems driving conveyors and tracks.
4. Abertura de alimentação: Capable of accepting feed material up to approximately 8.5 polegadas (215 milímetros) em tamanho, depending on feed arrangement and material characteristics.
5. Crushing Chamber Options: Offered various chamber configurations (por exemplo, CE - Extra Coarse, C - Grosso, M - Médio, F - Multar) to optimize performance for different feed sizes and desired end products.

6. Configuração lateral fechada (CSS) Faixa: Wide hydraulic adjustment range, typically from approx. 10mm to 40mm (3/8" para 1 5/8”), allowing precise control over product size without needing to change concaves/mantles immediately.
7. Capacidade: Production rates varied significantly based on feed material type, gradação, chamber selection, e configuração CSS. Under optimal conditions with suitable feed, potential throughput could reach several hundred tonnes per hour.
8. Transportador de Produto: 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. Mobilidade: Mounted on a heavy-duty tracked undercarriage providing good stability during operation and mobility around site or between sites.
