Equipped with a mobile chassis, the whole unit can relocate independently and be put into use on‑site without building a fixed production site. It can directly enter various construction sites to complete on‑site crushing operations. Featuring high flexibility, fast commissioning and cost‑saving performance, it is widely applied in mine exploitation, construction waste recycling, road infrastructure construction, river rock processing, solid‑waste treatment and other fields, and has become mainstream crushing equipment in the sand‑aggregate industry and engineering construction sector.

2. Working Principle of Mobile Crushing Station

Mobile crushing station adopts an integrated vehicle‑mounted design. The crushing main unit, vibrating feeder, multi‑layer vibrating screen, belt conveyor system and electric‑power control system are highly integrated on the mobile chassis. After transported to the construction site, no concrete pouring or equipment assembly is required. It can be quickly put into production only after simple leveling and commissioning. Raw stones, construction waste, ores and other materials are evenly fed into the crushing host by the feeder and finely processed through extrusion, impact, inter‑particle crushing and other technologies. Then materials are graded and screened by screening equipment to separate finished sand and aggregate of different specifications. The whole set of production procedures including crushing, screening and discharging are completed in one‑stop manner, greatly simplifying the crushing production process and improving construction efficiency.
