AI Technical Summary
Existing reciprocating crushing devices use a vertical single reciprocating impact mechanism, which requires the equipment to be completely stopped before the feed inlet can be opened or closed. This results in the loading and unloading process and the crushing operation not being able to proceed in parallel, leading to low overall production efficiency and poor material handling continuity.
The system uses an eccentric cam to drive multiple breaker hammers to simultaneously impact and crush materials, and uses a screening component to screen them in real time. This enables the synchronous operation of the feeding, crushing, and screening processes, allowing materials to flow continuously within the equipment, avoiding downtime for loading and unloading, and achieving continuous production throughout the entire process.
It realizes continuous production throughout the entire process of manufactured sand crushing, improves production efficiency, avoids process interruptions caused by the shutdown and unloading of traditional equipment, and facilitates rapid adjustment of screening accuracy.
