The Extec X44 SBS Cone Crusher: Technical Specifications and Operational Profile

The Extec X44 SBS cone crusher represented a significant step in mobile crushing technology when introduced prior to Extec's acquisition by . Designed for high productivity and versatility in demanding secondary and tertiary crushing applications, the X44 combined robust construction with advanced cone crusher design principles. While no longer in production as Extec models transitioned under the Mobile Crushers and Screens banner (with successors like the QH440/QH441), understanding its specifications remains valuable for operators managing existing units or evaluating used equipment.

المواصفات الأساسية:

1. Cone Crusher Unit:
نموذج: 44SBS Cone (Extec sourced and integrated cone units).
Cone Head Diameter: 44 بوصة (1,118 مم).
سحق تصميم الغرفة: Optimized geometry based on 's SBS (Spring Box Support) design for efficient reduction and consistent product shape.
الحد الأقصى لحجم التغذية: Up to approximately 8 بوصة (200 مم), depending on material type and chamber configuration.
