How mobile impact crusher plant works? In the mining and quarry industry, a mobile impact crusher plant is usually the secondary crushing machine to process rocks or ores from the primary jaw crusher plant. After impact crusher machine crushing, precisely shaped cubical end products are fed to vibrating screen to get different size material, 0-5mm, 5-10mm, 10-20mm, 20-40mm, or some other required size. The vibrating screen is designed to be on the same level as the impact crusher. The oversized material from the first layer could be fed to the impact crusher directly to crush again. Another required size is sent to stock ground by belt conveyor. Compared to a stationary stone crusher plant, it has good mobility and can extend together with the raw materials site or construction site, and has many types of combinations to satisfy the processing needs of different materials.
