Integration of CRS cross roll screen and PCKF reversible hammer crusher 1. Much less overcrushing 2. Energy and cost saving 3. Small space occupation (less than 3m high) 4. More screening to reduce crusher load Features: 1. Creative integration of CRS roller screen and PCKF reversible hammer crusher 2. Functions: screening, material distribution, fine crushing 3. Small space occupation (total height of the machine less than 3m) 4. Just one storey is enough for the machine (save construction cost) 5. Applicable to various ROM coal, middlings, wet coal and high moisture coal 6. High screening efficiency to reduce crushing load 7. Crushing mechanism adopts advanced large crushing chamber and short cylindrical hammer. It is equipped screening deck to guarantee 100% qualified particle size. Working Principle: The coal gets into the screening mechanism (CRS cross roller screen), qualified coal particles go though the screen, while large coal lumps move forward to the crushing mechanism for fine crushing.
