The continuous and compact coal crushing plant is widely deployed across diverse open-pit mining operations. Centered on the mineral sizer as the primary crushing unit, the system integrates feeding, crushing, screening, and conveying functions for a broad range of bulk materials.
Materials are gravity-fed directly into the feed hopper and subsequently conveyed uniformly to the primary mineral sizer via an apron feeder. The mineral sizer reduces oversized feed (800–1500 mm) to a medium-size product fraction (250–500 mm).
The medium-size material stream is conveyed to the vibrating screen via a belt conveyor for size-based classification, thereby preventing over-crushing and preserving product integrity.
Oversize material retained on the vibrating screen is gravity-fed via a dedicated chute to the secondary mineral sizer, where it is reduced to the specified final product size (30–100 mm). The resulting product is then conveyed to the stockpile area or downstream processing equipment by the main belt conveyor.
