Abstract

The invention discloses aggregate crushing multi-stage screening equipment applied to asphalt mixture preparation, relates to the technical field of asphalt raw material screening, and aims to solve the problem that a gap between a movable cutter and a fixed cutter cannot be automatically adjusted according to actual requirements of mixture preparation in the crushing process. The device comprises a bottom plate and a machine table plate arranged above the bottom plate in a suspended mode. According to the invention, on one hand, the processing step of recycling the asphalt aggregate to complete crushing and screening is adopted, and the completely crushed asphalt aggregate is continuously subjected to fine screening; on the other hand, the crushing efficiency of the current equipment is comprehensively judged by measuring the crushing coefficient through the intelligent industrial control module, and the gap between the movable cutter and the fixed cutter is automatically adjusted according to the measured crushing coefficient, so that the gap between the movable cutter and the fixed cutter meets the aggregate crushing machining requirement of the recycling requirement, continuous fine screening is completed, and finally crushing and screening integrated machining is achieved; the continuous supply of raw materials for preparing the asphalt mixture is facilitated.
